BACKGROUND OF THE INVENTION
This invention relates to a document editing apparatus for editing
documents or manuscripts containing characters and images without any hand
work.
The rationalization of the office works is now under way under the name of
the office automation. For the office works a most important consideration
is paid to the proper management and utilization of documents. In order to
utilize, for example, the documents without being hoarded, it is desirable
to edit them in more utilizable form.
A simplest editing method is to manually stick cut regions of documents on
a sheet. This method is very uneconomical from the standpoint of the
preservation of the documents as well as the effective utilization of
labor. As a solution to this problem, the following methods may be
considered.
A first method is to enter specific marks and symbols designating an
editing operation on a specific sheet and read out them by a facsimile
unit so that the editing operation is carried out. In this method, it is
necessary for an editor to designate cut regions of documents and
corresponding sticking regions of the sheet. With the editing designation
marks entered on the document, the document is soiled, presenting a
document management problem. The use of the specific sheet prevents the
wide acceptance of the image editing apparatus.
A second method is to perform an editing operation utilizing a computer. In
this method, an editing mode and editing regions are designated through a
keyboard, while displaying the document on a display unit. This method is
desirable from the standpoint of the management of documents, because the
documents can be stored as image data. It is necessary, however, for the
editor to designate the cut regions of the documents and corresponding
sticking regions of the sheet to the apparatus through the keyboard. It is
difficult and time-consuming to prepare a new document by, for example,
cutting desired regions from a plurality of documents and sticking them on
a sheet of paper. For this reason, the editing operation depends much on
the skill of the editor.
SUMMARY OF THE INVENTION
An object of this invention is to provide an image editing apparatus which
can prepare a new document by extracting out of existing documents the
image data of any proper regions and synthesizing them, whereby a ready
editing operation is performed.
According to this invention a plurality of basic sticking patterns are
initially prepared, according to which a plurality of cut regions from a
plutality of documents are stuck on a sheet. A sticking region computer
calculates the coordinates of those sticking regions corresponding to the
cut regions in connection with the respective sticking patterns. An image
processor causes image information of the respective cut regions which are
stored in a first RAM to be transferred to the memory location of a second
RAM which is designated by the calculated coordinate data of the sticking
regions. An image editing process is performed with respect to the
respective basic sticking patterns and displayed on a CRT display.
According to this invention no complicated operation is required, because a
plurality of cut regions are automatically stuck on a sheet according to
the sticking patterns which are initially prepared in the image editing
apparatus. During the editing operation, the sticking of the cut regions
are performed in substantially fixed manner. If three patterns of high
frequency are initially prepared, they are applicable to almost any case.
It is possible for the editor to select a desired one out of the documents
which are edited according to a plurality of patterns.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
An editing apparatus of FIG. 1 comprises an input section 11, output
section 12, control section 13, image processor 14, instruction input
section 15, sticking region computer 16 and reduction circuit 17. An
editing operation is automatically performed by control section 13 and
image processor 14 which are comprised of a microcomputer such as Intel
8085. Control section 13 controls the whole operation of the apparatus,
and image processor 14 effects the editing control such as the calculation
of sticking regions on a sheet and transfer of the image information.
Reference numeral 20 designates a control signal bus connecting control
section 13 to the associated parts and reference numeral 21 designates a
bus for image processing signals which connects image processor 14 to the
parts associated with the editing operation. Reference numeral 22 denotes
an image signal bus for connecting image processor 14 to those parts which
handle the image information.
The editing properly performed by the image editing apparatus of this
invention is to stick, for example, cut regions C.sub.1 and C.sub.2 of a
first document 101 and cut region C.sub.3 of a second document 102 on one
sheet 103 as shown in FIG. 3. According to this invention a plurality of
basic sticking patterns are prepared to permit a plurality of cut regions
to be stuck on one sheet. Where a plurality of basic patterns are found
which permits the sticking of a plurality of cut regions, it is possible
to select one of them. For convenience of explanation it is assumed that
documents 101, 102 to be cut are of the same size (for example, an A4
size) as that of sheet 103 on which the cut regions are stuck.
Input section 11 includes a scanner 111 and a document file 112 using an
optical disc or a magnetic disc. A document to be edited is an input
document 18 to be read out by scanner 111 or a document stored in file 112
which is retrieved by instruction input section 15. Such document is
displayed on a first CRT (cathode ray tube) display 121 of output section
12. While observing the document on display 121, two points P.sub.C0 and
P.sub.C1 on a diagonal line of a rectangular region to be cut which is
shown in FIG. 2 are designated by a light pen of instruction input section
15. As a result, the coordinate (X.sub.C0, Y.sub.C0) and (X.sub.C1,
Y.sub.C1) on the two points are detected in instruction input section 15
and these coordinate data are stored in a RAM (random access memory) in
sticking region computer 16. The other regions to be cut of the same
document and/or the regions to be cut of another document are designated
in a similar manner. When the regions to be cut are so designated, image
processor 14 extracts the image information of the cut regions on the
basis of the coordinate data of the cut regions to permit them to be
stored in first buffer 124 (512 K byte RAM). When the designation of all
the cut regions is completed, the coordinate data (X.sub.D0, Y.sub.D0
through X.sub.D5, Y.sub.D5) of the sticking regions as indicated by
D.sub.1 D.sub.2, D.sub.3 on a sheet 103 of FIG. 3 are calculated on the
basis of the coordinate data of the cut regions which are stored in
sticking region computer 16.
Stated in more detail, sticking region computer 16 comprises a RAM for
storing the coordinate data of the cut regions and ROM (read only memory)
for storing the process steps. ROM further stores information on six basic
sticking pattern as shown in FIGS. 5A to 5F, as to how cut regions
C.sub.1, C.sub.2, C.sub.3 are stuck on sheet 103 and data (X.sub.max,
Y.sub.max of sheet 103 as shown in FIG. 4) as to the size of sheet 103.
Image processor 14 judges whether or not all the cut regions C.sub.1,
C.sub.2, C.sub.3 can be stuck on sheet 103 in connection with all the
basic sticking patterns on the basis of the coordinate data of the cut
regions which are stored in sticking region computer 16, judges whether or
not the reduction of the cut regions is necessary for sticking, and finds
the coordinates X.sub.D0, Y.sub.D0 through X.sub.D5, Y.sub.D5 of regions
D.sub.1, D.sub.2, D.sub.3 which can be stuck on sheet 103 as shown in FIG.
3. The coordinate data of sticking regions D.sub.1, D.sub.2, D.sub.3 are
computed with respect to those basic patterns which are judged as fit
patterns. These coordinate data, together with the coordinate data of the
cut regions, are stored in RAM. In an example of FIG. 3, cut regions
C.sub.1, C.sub.2, C.sub.3 are stuck on sheet 103 according to the basic
pattern as shown in FIG. 5A.
When the sticking regions are computed, the image editing process is
performed. In the image editing process, the transfer of image information
is carried out. That is, image processor 14 designates the addresses of
sticking regions Dl, D2, D3 of a second buffer (512 K byte RAM) 125 on the
basis of the computed coordinate data and transfer the image information
of the cut regions stored in first buffer 124 to the memory locations of
second buffer 125 which are designated by these addresses.
The image information of sticking regions D.sub.1, D.sub.2, D.sub.3 are
stored in the A4 size memory locations of second buffer 125 in such a
relation as indicated on the right side of FIG. 3 which shows an edited
document. The "edited" information are stored in second buffer 125 for
each basic pattern which permits the sticking of cut regions C.sub.1,
C.sub.2, C.sub.3. The "edited" image information associated with A4 size
which are stored in second buffer 125 are displayed on second CRT display
122 for each fit basic pattern. The editor can select a desirable pattern.
The image information edited according to the selected pattern may be
stored in image file 112 and/or may be printed out by a printer 123 as a
hard copy 19. The operation of the editing apparatus of FIG. 1 will be
described below in more detail by referring to a flow chart.
FIG. 6 shows a whole flow chart associated with the operation of the image
editing apparatus.
At the start of an editing operation, the editor retrieves a to-be-edited
document stored in image file 112 through a keyboard of instruction input
section 15 at step S.sub.1. The document to be edited may optically be
read out by scanner 111. At step S.sub.2, the retrieved document is
displayed on first CRT display 121. The editer goes ahead with the editing
operation, while watching first CRT display 121.
When the document is displayed on CRT display, the editor designates a cut
region C, as shown in FIG. 2, by pointing at two points P.sub.C0, P.sub.C1
on the cut region C with the light pen of instruction input section 15.
When the designation of one cut region is completed, the editor indicates
the completion of the designation, through the keyboard. At step S.sub.4,
judgement is made as to whether or not the designation of the cut region
is completed. If the designation of cut region is completed, then the
process goes to step S.sub.5.
At step S.sub.5, image processor 14 stores the coordinate data (X.sub.C0,
Y.sub.C0, X.sub.C1, Y.sub.C1) on the two points P.sub.C0, P.sub.C1 of the
cut region C which are detected at instruction input section 15 in the RAM
of sticking region computer 16 and the image information of the cut region
of document in first buffer 124 on the basis of the detected coordinate
data. When the retrieval of the documents to be edited and the designation
of the regions are completed, the process goes to the next step.
In designating the coordinates of the cut region at step S.sub.3, the
editor may input, through the keyboard, information as to the attributes
of the cut region, such as the priority, inhibition of the reduction and
the order of cutting. The information as to the attributes, together with
the coordinate data, are stored in RAM of sticking region computer 16.
The steps heretofore mentioned involve the intervention of the editor.
When, as shown in FIG. 3 for example, the cut regions C.sub.1, C.sub.2 of
first document 101 and cut region C.sub.3 of second document 102 are
designated, the coordinate data (X.sub.C0, Y.sub.C0) through (X.sub.C5,
Y.sub.C5) on points P.sub.C0 through P.sub.C5 of the cut regions are
stored in RAM and the image information of the cut regions are stored in
first buffer 124 according to the order of the designation.
At step S.sub.7, the sticking regions corresponding to cut regions C.sub.1,
C.sub.2, C.sub.3 are calculated.
As will be set out below, at this step, examination is made as to whether
or not the cut regions C.sub.1 C.sub.2, C.sub.3 can be stuck on the sheet
according to the basic sticking patterns as shown in FIGS. 5A through 5F.
The coordinates of the sticking regions are computed for each fit basic
pattern. These coordinate data, together with the coordinate data of the
cut regions, are stored in the RAM of sticking region computer 16. If size
reduction is necessary for sticking, the coordinates of the reduced
sticking regions are calculated. When the coordinates of the sticking
regions are calculated, the image editing (the transfer of the image
information) is carried out at step S.sub.8. Namely, at this step, image
processor 14 transfers the image information from first buffer 124 to
second buffer 125 on the basis of the coordinate data of the sticking
regions. The image editing is carried out for each fit basic pattern.
At step S.sub.9, the image processor 14 reads the "edited" image
information out of second buffer 125 for each fit basic pattern according
to an instruction of the editor and displays them on CRT display 122.
At step S.sub.10, the editor can select a desired edited document through
the keyboard, while viewing the screen of second CRT display 122. A step
S.sub.11, the selected document is printed out by printer 123 or stored in
image file 112.
The sticking region computing process will be explained below by referring
to a detailed flow chart of FIG. 7 which is related to the sticking region
computing step of FIG. 6.
At step S.sub.701, judgement is made as to whether or not the cut regions
can be stuck on the sheet, according to the basic patterns as shown in
FIG. 5A to 5F, on the basis of the coordinate data of cut regions C.sub.1,
C.sub.2, C.sub.3 which are stored in the RAM in sticking region computer
16.
When the coordinates of two points on the diagonal line of cut regions
C.sub.1, C.sub.2, C.sub.3 are determined as shown in FIG. 4, the lateral
length (the width) X and longitudinal length (the height) Y of the cut
regions can readily been obtained and examination is made as to whether or
not the cut regions can be stuck on the sheet 103 of a dimension X.sub.max
.times.Y.sub.max according to the basic patterns.
FIG. 5A shows a basic pattern for sticking three cut regions in the
vertical direction and FIG. 5B shows a basic pattern for sticking three
cut regions such that one cut region is arranged at the upper section of
the pattern with the remaining two cut regions located side by side in the
horizontal direction. FIG. 5C shows a basic pattern for sticking three cut
regions such that two cut regions are arranged side by side at the upper
section of the pattern with the remaining one region located at the lower
section thereof. FIG. 5D shows a basic pattern for sticking three cut
regions side by side in the horizontal direction. FIG. 5E shows a basic
pattern for sticking three cut regions such that one cut region is
arranged on the left side with the remaining two cut regions located one
above the other on the right side of the pattern. FIG. 5F shows a basic
pattern for sticking three cut regions such that two cut regions are
arranged one above the other at the left side of the pattern with the
remaining one cut region located at the right side thereof. In this
embodiment, as stated above, it is assumed that the document to be edited
is of the same size as that of the document on which the cut regions are
stuck. Therefore, the width (X.sub.1, X.sub.2, X.sub.3) of the cut region
is below X.sub.max and the hight (Y.sub.1, Y.sub.2, Y.sub.3) thereof is
below Y.sub.max.
At step S.sub.701, image processor 14 finds a sum (Y.sub.1 +Y.sub.2
+Y.sub.3) of heights of cutting regions C.sub.1, C.sub.2, C.sub.3. If
Y.sub.1 +Y.sub.2 +Y.sub.3 .ltoreq.Ymax, the cut regions C.sub.1, C.sub.2,
C.sub.3 are judged as being capable of being stuck on the sheet according
to the sticking pattern of FIG. 5A. If X.sub.1 +X.sub.2 +X.sub.3
.ltoreq.Xmax, the cut regions C.sub.1, C.sub.2, C.sub.3 are judged as
being capable of being stuck on the sheet according to the sticking
pattern of FIG. 5D.
For sticking the cut regions on the sheet according to the pattern of FIG.
5B, there are three sticking ways depending on which one of the cut
regions C.sub.1, C.sub.2, C.sub.3 is located at the upper section of the
pattern. When X.sub.2 +X.sub.3 .ltoreq.X.sub.max, Y.sub.1 +Y.sub.3
.ltoreq.Y.sub.max, it is judged that the three cut regions C.sub.1,
C.sub.2, C.sub.3 can be stuck on the sheet according to the pattern of
FIG. 5B with the cut region C.sub.1 located at the upper section of the
pattern. When X.sub.1 +X.sub.3 .ltoreq.X.sub.max, Y.sub.1 +Y.sub.2
.ltoreq.Y.sub.max and Y.sub.2 +Y.sub.3 .ltoreq.Y.sub.max, the three cut
regions can be stuck on the sheet according to the pattern of FIG. 5B with
the cut region C.sub.2 located at the upper section of the pattern. When
X.sub.1 +X.sub.2 .ltoreq.X.sub.max, Y.sub.1 +Y.sub.3 .ltoreq.Y.sub.max and
Y.sub.2 +Y.sub.3 .ltoreq.Y.sub.max , the three cut regions C.sub.1,
C.sub.2, C.sub.3 are stuck on the sheet according to the pattern of FIG.
5B with the cut region C.sub.3 located on the upper section of the
pattern. In this way, the judgement is continued until one of the three
sticking ways is found usable. With respect to each of the basic patterns
as shown in FIG. 5C, 5E and 5F, there are three sticking ways and such
judgement is made according to the respective requirements.
When, at step S.sub.702, the cut regions are judged as being not capable of
being stuck on the sheet according to the respective basic pattern as they
stand, a reduction flag is attached at step S.sub.703 to the data of the
respective cut regions, indicating that it is impossible to stick the cut
regions on the sheet according to the judged basic pattern. At step
S.sub.704, examination is made as to whether or not the judgement is made
in connection with all the basic patterns. If the answer is in the
negative, the process goes back to step S.sub.701. Then, the cut regions
are judged in connection with the next basic pattern. Where the judgement
of the cut regions in connection with all the basic patterns is completed,
judgement is made, at step S.sub.705, as to whether or not there is any
basic pattern with no reduction flag attached thereto, i.e., any basic
pattern which permits the sticking of the regions C.sub.1, C.sub.2,
C.sub.3. If the answer is in the affirmative, the basic pattern with the
reduction flag attached thereto is discarded at step S.sub.706. That, at
step S.sub.705, the answer is in the negative means that there is no basic
pattern with no reduction flag attached thereto, i.e., it is impossible to
stick the cut regions on the sheet according to each of all the basic
patterns without being reduced.
At step S.sub.707, judgement is made as to whether or not it is necessary
to reduce the cut region in connection with the individual basic pattern
on the basis of the reduction flag. If reduction is necessary, the
reduction process is carried out at step S.sub.709. At step S.sub.701, the
coordinate data of a new cut region which has been subjected to the
reduction process are stored in the RAM of sticking region computer 16. If
reduction is not necessary, the first coordinate data of the cut region
are stored.
At step S.sub.711, judgement is made as to whether or not it is necessary
to reduce the cut region in connection with all the basic patterns. If the
answer is in the negative, those steps beginning with step S.sub.707 are
repeated in connection with the remaining basic patterns. If the answer is
in the affirmative, at step S.sub.712, calculation is made of the
coordinates of the sticking regions D.sub.1, D.sub.2, D.sub.3 in the fit
basic pattern according to an order of the areas of cut regions C.sub.1,
C.sub.2, C.sub.3 as will be set out later in more detail. At step
S.sub.713, judgement is effected as to whether or not the calculation of
the sticking regions in connection with all the basic patterns is
completed. If the answer is in the affirmative, then an image editing
process is performed.
Step S.sub.712 at which the sticking regions are calculated will be
explained below by referring to FIG. 8.
At step S.sub.720, image processor 14 calculates the areas of new cut
regions C.sub.1 ', C.sub.2 ', C.sub.3 ' on the basis of the coordinate
data of the new cut regions to be stuck and determines the order of these
areas. For example, assume that C.sub.1 '>C.sub.2 '>C.sub.3 '. For
convenience of explanation, let it be assumed that the areas of the cut
regions are originally C.sub.1 (=C.sub.1 ')>C.sub.2 (=C.sub.2 ')>C.sub.3
(=C.sub.3 ').
At step S.sub.721, the coordinates of sticking region D.sub.1 are
calculated. The coordinates (X.sub.D0, Y.sub.D0) on a point P.sub.D0 of
region D.sub.1 are stored, as the head address of the basic pattern of
FIG. 5A, in the ROM of sticking region computer 16. Thus, the coordinates
on the point P.sub.D1 are calculated as X.sub.D1 =X.sub.D0 +X.sub.1 and
Y.sub.D1 =Y.sub.D0 +Y.sub.1. At step S.sub.722, the coordinates of
sticking region D.sub.2 is calculated and the coordinates on the point
P.sub.D2 are found as X.sub.D2 =X.sub.D0 and Y.sub.D2 =Y.sub.D1 +.alpha.,
where .alpha. corresponds to a predetermined spacing. The coordinates on
the point P.sub.D3 are calculated as X.sub.D3 =X.sub.D2 +X.sub.2 and
Y.sub.D3 =Y.sub.D2 +Y.sub.2. At step S.sub.723, the coordinates of
sticking region D.sub.3 are found. The coordinates on the point P.sub.D4
are found as X.sub.D4 =X.sub.D0 and Y.sub.D4 =Y.sub.D3 +.alpha.', where
.alpha.' also corresponds to a predetermined spacing. The coordinates on
the point P.sub.D5 are found as X.sub.D5 =X.sub.D0 and Y.sub.D5 =Y.sub.D4
+Y.sub.3. In this way, the coordinates of the sticking regions D.sub.1,
D.sub.2, D.sub.3 are found in connection with each of the fit basic
patterns. The coordinate data of those sticking regions are stored in the
RAM of sticking region computer 16 for each basic pattern.
The image editing process will be explained below by referring to the flow
chart of FIG. 9.
At step S.sub.730, image processor 14 reads image information in cut region
C.sub.1 out of first buffer 124 to temporarily store them therein. At step
S.sub.731, image processor 14 designates that address of a memory area of
second buffer 125, on the basis of the calculated coordinate data of the
sticking region D.sub.1, where the image information in cut region C.sub.1
are to be stored. At step S.sub.732, image processor 14 writes the image
information in cut region C.sub.1 into the address which is designated by
second buffer 125.
At step S.sub.733, judgement is effected as to whether or not the transfer
of the image information of all the cut regions is completed. If the
answer is in the negative, the above-mentioned steps are repeated. As a
result of these processes, the image information of sticking regions
D.sub.1, D.sub.2, D.sub.3 are stored in an A4 size memory area of second
buffer 125 in that relation as shown in FIG. 3. The edited image
information is stored in second buffer 125 for each of fit basic patterns.
The resuction process step S.sub.709 will be explained below in more detail
by referring to FIG. 10.
At step S.sub.740 the attributes of the cut regions are judged and if the
reduction is not inhibited for the cut regions, the process goes to step
S.sub.741. At step S.sub.740 if reducible cut regions C.sub.1, C.sub.2,
C.sub.3 are edited such that they are arranged vertically according to the
basic pattern as shown, for example, in FIG. 5A, the heights Y.sub.1 ',
Y.sub.2 ', Y.sub.3 ' of the cut regions C.sub.1, C.sub.2, C.sub.3 are
arbitrarily found to provide Y.sub.1 '+Y.sub.2 '+Y.sub.3
'.ltoreq.Y.sub.max. At step S.sub.742, judgement is performed as to
whether or not Y.sub.1 ', Y.sub.2 ', Y.sub.3 ' are greater than Y.sub.min.
With the height of a pre-edited display character and readable minimum
value of the reduced character representing A and B, respectively,
Y.sub.min is given by
Y.times.B/A
At step S.sub.741, judgement is made as to whether or not Y.sub.1
'.gtoreq.Y.sub.1min, Y.sub.2 '.gtoreq.Y.sub.2min and Y.sub.3
'.gtoreq.Y.sub.3min. If the answer is in the negative, i.e., the reduced
character is illegible, the basic pattern as shown in FIG. 5A is
abandoned. If at step S.sub.742 the answer is in the affirmative, the
process goes to step S.sub.743 in which reduction rates Y.sub.1 '/Y.sub.1,
Y.sub.2 '/Y.sub.2 and Y.sub.3 '/Y.sub.3 are calculated the reduction rates
are stored in the RAM of sticking region computer 16. The coordinates of
points P.sub.D1 through P.sub.D5 of sticking regions D.sub.1, D.sub.2,
D.sub.3 as shown in FIG. 3 are calculated on the basis of the reduction
rates. Where the sticking pattern as shown in FIG. 3 is involved,
calculation is made of the coordinates of the sticking regions which are
reduced in the Y-axis direction only. These coordinate data are stored in
the RAM of sticking region computer 16. In the editing process, the image
information to be stored in that address of second buffer 125 which is
designated by image processor 14 and based on the reduced coordinates is
supplied from image processor 14 through reduction circuit 17 to second
buffer 125. Reduction circuit 17 reduces the image information in
accordance with the reduction rate for each region. The reduction process
is performed for each basic pattern as shown in each of FIGS. 5A through
5F. Those basic patterns which make the image not readable upon reduction
are discarded.
It is desirable to calculate the sticking regions according to the
designation order of the cut regions, i.e., the order of cutting. As set
out above, those data (hereinafter referred to the designation data)
relating to the order of cutting are obtained at step S.sub.3. Suppose,
for example, that designation is effected in the order of cut regions
C.sub.1, C.sub.2 and C.sub.3 as shown in FIG. 3. The coordinate data and
designation data are stored in the RAM of sticking region computer 16. The
following steps correspond to the steps in FIG. 7. Like step 701,
judgement is made as to whether or not cut regions C.sub.1, C.sub.2,
C.sub.3 can be stuck on the sheet, according to the basic patterns of
FIGS. 5A through 5H, on the basis of the coordinate data of the cut
regions.
It is to be noted that, in this case, the requirement is given that the cut
regions C.sub.1, C.sub.2, C.sub.3 are stuck on the sheet in this order
according to the basic pattern. In connection with the basic pattern as
shown in FIG. 5A, judgement is made as to whether or not cut regions
C.sub.1, C.sub.2, C.sub.3 can be stuck on the sheet as shown in Fig. 11A.
In connection with the basic patterns as shown in FIGS. 5B through 5F,
judgement is effected as to whether or not cut regions C.sub.1, C.sub.2,
C.sub.3 can be stuck on the sheet as shown in Figs. 11B through 11F. This
judgement is the same as that at step 701 and is performed by the sum of
heights or widths of cut regions C.sub.1, C.sub.2, C.sub.3. The sticking
regions of the sheet are calculated hereinafter in the order of cutting by
the same processing steps.
In the above-mentioned embodiment, three cut regions have been used, but
two or four or more cut regions may be used. In this case, the basic
sticking pattern data is stored in the ROM of sticking region computer 16
for each number (2, 3, 4 . . . ) of used cut regions.
The cut region has been explained as being a rectangular region, because
the designation of the rectangular region is easiest. Circular, square and
polygonal regions may be designated at the user's request. Not only the
rectangular coordinates, but also the polar coordinates, may be used for
coordinate designation. The rectangular region may be designated by two
points on the diagonal, as well as one point and length of two sides.
Although, in the embodiment of this invention so far described, reduction
circuit 17 is used, a circuit for selectively performing reduction and
enlargement of image information may be used.
An image editing apparatus of this invention may be coupled to a facsimile
unit so as to edit received documents and transmit the edited documents.
