image data of a document, original, or the like on a pixel unit basis, for
converting it into a digital signal, and for processing this digital
signal and, more particularly, the present invention relates to an image
processing system capable of processing one pixel of image data by both of
the binary digital signal and the multivalue digital signal.
2. Related Background Art
Hitherto, there has been generally known an image processing system in
which image data such as diagram, document, or the like is read on a pixel
unit basis by a photoelectric converting device or the like and converted
into a binary digital signal and subjected to processes such as editing,
display, storage, and the like. On the other hand, in recent years, there
has been developed an image processing system in which image data is
converted into a multivalue digital signal and processed in order to
process image data having a half tone expression such as a photograph or
the like and further to perform image processes such as gradation
conversion, edge emphasis, cut-out of a target image data, etc.
However, in the image processing system for performing image processes on
the signal (hereinafter, referred to as the binary image data) derived by
converting image data into a binary digital signal, the image processes
cannot be performed on the signal (hereinafter, referred to as the
multivalue image data) derived by converting image data into a multivalue
digital signal. In addition, even in the image processing system for
performing image processes on multivalue image data, the image processes
cannot be performed on the binary image data. In other words these image
processing systems lack flexibility.
Hitherto, there has been known a method whereby multivalue image data is
expressed as a pseudo half tone by binary image data on the basis of a
dither method, a density pattern method, or the like. However, there is a
drawback such that the picture quality deteriorates because of the
deterioration of the gradation and resolution, the occurrence of the
moire, and the like.

In consideration of the foregoing points, it is an object of the present
invention to eliminate the above-mentioned drawbacks.
Another object of the invention is to provide an image processing system
having a high degree of generality in which binary image data and
multivalue image data are integrated and image processes such as document
editing, print-out, and the like can be performed.
Still another object of the invention is to provide an image processing
system having binary image processing means and multivalue image
processing means capable of performing the transmission and reception of
data therebetween.
Still another object of the invention is to provide an image processing
system having binary image processing means, multivalue image processing
means, and A/D converting means for converting a video signal into
multivalue image data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
An embodiment of the present invention will be described in detail
hereinbelow with reference to the drawings.
FIG. 1 is a constitutional diagram of an image processing system to which
the invention is applied.
In FIG. 1, reference numerals 1-1, 1-2, . . . , 2-1, and 2-2 denote binary
image processing work stations (hereinafter, referred to as binary WS)
which can edit and display binary image data; 3-1, 3-2, . . . indicate
image readers (hereinafter, referred to as binary RD) to binarize and read
image data; and 4-1, 4-2, . . . represent image printers (hereinafter,
referred to as binary PR) to print the binarized image data. The binary RD
3-1, 3-2, . . . and binary PR 4-1 and 4-2 are connected to the binary WS
2-1, 2-2, . . . , respectively. The binary WS 2-1, 2-2, . . . can transmit
and receive binary image data to and from reader/printer systems
(hereinafter, referred to as binary RD/binary PR systems) 5-1, 5-2, . . .
each consisting of the binary image reader and binary image printer
through a network (hereinafter, abbreviated to LAN) 12, respectively.
With the foregoing constitution, the binary WS 1-1, 1-2, . . . can receive
the binary image data from either one of the binary RD/binary PR systems
5-1, 5-2, . . . through the LAN 12 and perform the editing such as
cut-out, of the binary image data, and enlargement, reduction, rotation,
movement, synthesis, etc. of the cut-out binary image data while
displaying the editing content on a display device. These binary WS can
transfer the binary image data obtained finally to either one of the
binary RD/binary PR systems 5-1, 5-2, . . . through the LAN 12 and can
print this data. In addition, the binary WS can also store the binary
image data in an external memory device of the binary WS or into either
one of memory device file servers (hereinafter, referred to as FS) 6-1 and
6-2 connected via the LAN 12. The binary WS 2-1, 2-2, . . . can also
transmit and receive binary image data to and from the binary RD/binary PR
systems on the network, can directly read the binary image data from the
binary RD 3-1, 3-2, . . . connected, and can also print the binary image
data using the binary PR 4-1, 4-2, . . . .
Further, numerals 7-1, 7-2, . . . , 8-1, 8-2, . . . denote multivalue image
processing work stations (hereinafter, abbreviated to multivalue WS)
capable of editing and displaying multivalue image data; 9-1, 9-2, . . .
indicate image readers (hereinafter, referred to as multivalue RD) to
convert image data into multivalues and read; and 10-1, 10-2, . . .
represent image printers (hereinafter, referred to as multivalue PR)
capable of printing the image data converted into the multivalue data by
reproducing half tones.
The multivalue WS 7-1, 7-2, . . . , 8-1, 8-2, . . . can receive the
multivalue image data from either one of the multivalue RD, can edit and
display it, can transfer the multivalue image data to either one of the
multivalue PR, can print, and can also store in either the FS 6-1 or the
FS 6-2 in a manner similar to the case of the binary WS. The multivalue
image data can be also subjected to editing such as cutout, enlargement,
reduction, rotation, movement, synthesis, etc. of the cut-out portions,
gradation conversion, edge emphasis, etc.
Either one of a television (TV) camera input device 68, a VTR (video tape
recorder) 69, and a television (TV) tuner 70 is connected to the
multivalue WS 8-2.
FIG. 2 is a block diagram showing an internal constitution of the binary WS
1-1, 1-2, . . . , 2-1, 2-2, . . . . As fundamental components, there are
provided: an input keyboard 13; a pointing device 14; a keyboard interface
KBD-I/F 15; a CPU 22; a program memory 23 including an MMU (memory
management unit); an interface FD/HD-I/F 24 to drive a hard disk and to
drive a floppy disk; a hard disk drive (hereinafter, referred to as an HD)
25; a floppy disk drive (hereinafter referred to as an FD) 26; a CRT
display 16; and a video RAM (hereinafter, referred to as a binary VRAM) 17
for display. A bit manipulation unit (hereinafter, referred to as a BMU)
18 can transfer a large amount of data at a high speed on a word unit
basis and on a bit unit basis among the program memory PMEM 23, the binary
VRAM 17, the input/output apparatuses, etc. without passing through the
CPU 22. The BMU 18 further has the logic arithmetic operating function of
transmission side data and reception side data, a rotating function, and a
variable magnification function. For the variable magnification function,
binary image data such as a diagram or the like and multivalue image data
such as a photograph or the like can be individually variably magnified.
Further, the binary WS has a compressing/expanding circuit (or compandor)
(hereinafter referred to as an MMR) 19 having the function to compress and
expand data and an interface LAN-I/F 20 to connect the binary WS and the
LAN. The binary WS may also have an optical disk (hereinafter, referred to
as an OD) 29 if a file of a large memory capacity is necessary and an
interface OD-I/F 28 for the OD 29.
The binary WS also has an interface binary LC-I/F 27 to directly connect
either or both of the binary RD3 and the binary PR4. Since the internal
structure of the LC-I/F 27 is well known, it is omitted. However, the
LC-I/F 27 has therein a buffer to store binary image data and has a
function to directly transfer the read data from the binary RD 3 to the
binary PR 4 and to realize the local copy.
The binary WS 1-1, 1-2, . . . receive the binary image data transmitted
through the LAN 12 by the LAN-I/F 20 and expanded by the MMR 19 and
transfer the image data to the PMEM 23 or binary buffer of the binary
LC-I/F 27. This data is edited by use of the function of the BMU 18 and
transferred to the binary VRAM 17, thereby enabling the edited image data
to be displayed on the CRT display 16. The edited binary image data can be
also stored into the HD 25, FD 26, and OD 29 and can be also transferred
to the binary PR 5-1 and 5-2 or FS 6-1 and 6-2 shown in FIG. 1 via the LAN
12. A multivalue/binary CV 21 has a function to convert multivalue image
data into binary image data and converts the multivalue image data
transferred through the LAN 12 into the binary image data and stores in a
binary buffer (BUF). Its internal constitution is as shown in FIG. 10. The
corresponding density pattern is transferred from a binarization pattern
ROM 54 to a binary BUF 55 in correspondence to one pixel of the multivalue
image data. Thus, the binary WS 1-1, 1-2, . . . , 2-1, . . . can
synthesize and edit the binary image data and multivalue image data as the
same binary image data and can transfer the resultant data to the binary
PR 4.
FIGS. 3 and 4 are block diagrams (the same components as those shown in
FIG. 2 are designated by the same reference numerals) showing internal
constitutions of the binary RD/binary PR systems 5-1, 5-2, . . . , FS 6-1,
6-2, . . . . In this constitution, the binary RD/binary PR systems 5-1,
5-2, . . . read image data and send as the binary image data to the LAN
12. Or, the systems 5-1, 5-2, . . . receive the binary image data from the
LAN 12 and print or can locally copy. On the other hand, the FS 6-1, 6-2,
. . . have functions to perform the ordinary file management and to store
binary and multivalue image data in the HD 25, FD 26, and OD 29.
FIGS. 5 and 6 (the same components as those shown in FIG. 2 are designated
by the same reference numerals) are block diagrams showing internal
constitutions of the multivalue WS 7-1, 7-2, . . . , 8-1, 8-2, . . . and
of the multivalue RD/multivalue PR systems 11-1, 11-2, . . . ,
respectively. The difference between these multivalue systems and the
binary RD/binary PR systems is the presence of a video RAM 32 and a
multivalue LC-I/F 34. The multivalue LC-I/F 34 is needed to connect the
multivalue RD 9 with the multivalue PR 10. To display multivalue image
data as an image, the multivalue VRAM 32 is necessary.
The multivalue LC-I/F 34 is constituted as shown in FIG. 7. The multivalue
RD 9 controlled by a controller 37 has functions to read out image data
through a thinning circuit 45 and write in a multivalue BUF 39 and to
separate the image data into an image area for the binary image data such
as diagrams, characters, etc. and an image area for the multivalue image
data having half tones such as a photograph or the like as necessary. The
image area separation data is stored in an image area BUF 40 through an
image area separation circuit 46. The data such as diagrams, characters,
etc. is binarized by a binarization circuit 42 and stored in a binary BUF
38. The multivalue image data in the multivalue BUF 39 can be also
transferred to the multivalue PR 10 and printed.
The binary image data in the binary BUF 38 is converted into the multivalue
data by a multivalue forming circuit 41 and is multiplexed with the
multivalue image data from the multivalue BUF 39 through a multiplexer
circuit 43 and can be transferred to the multivalue PR10. The multivalue
VRAM 32 is constituted as shown in FIG. 8. The VRAM 32 can store
multivalue image data in a multivalue BUF 53 and can display on the CRT
display 16. In addition, the binary image data can be stored in a binary
BUF 52 and can be multiplexed with the multivalue image data by the
multiplexer circuit 51 and can be displayed.
A binary/multivalue CV 33 has a function to convert binary image data into
multivalue image data or from multivalue image data into binary image
data. The internal constitution of the CV 33 is as shown in FIG. 11. The
CV 33 reads out the data from a multivalue BUF 56 and transfers the
corresponding density pattern from a binarization pattern ROM 57 to a
binary BUF 58 in correspondence to one pixel. If the binary image data is
the data such that the half tone expression is expressed by a density
pattern, the data is read out of the binary BUF 58 and the multivalue data
to express the gradation of corresponding one pixel is read out of a
multivalue forming pattern ROM 59 and transferred to the multivalue BUF
56.
Due to this, the multivalue WS 8-1, 8-2, . . . can synthesize and edit the
binary image data and multivalue image data as the same image data and can
also transfer the resultant data to the multivalue PR 10 and to the binary
PR 4.
On the other hand, when the TV camera input device 68 or VTR 69 is
connected to the multivalue WS or when the TV tuner 70 is connected
thereto through the VTR 69, in order to monitor these input data, the
multivalue VRAM 32 has functions to repeatedly write the multivalue image
data through a video signal sampling circuit 71 and an A/D converter 72
and to hold the data at that time by the operation to make a shutter of
the TV camera input device 68 operative. Further, the multivalue VRAM 32
has a function to transmit various kinds of monitoring commands of the TV
camera input device 68.
In the foregoing constitution, the multivalue WS can realize the functions
similar to those of the binary WS with respect to the multivalue image and
can process a multivalue image together with a binary image as necessary.
In order to discriminate the binary image data and multivalue image data as
mentioned above and to discriminate the data transfer among various kinds
of apparatuses, a data format on the LAN 12 can be realized as shown in
FIG. 9. In the diagram, reference numerals 47 and 48 denote ID
(identification) numbers indicative of the transmission side (i.e.,
transmitter) and the reception side (i.e., receiver). These ID numbers are
added from the transmission side. Numeral 49 denotes an ID number
indicative of the content of data. The number indicative of a binary image
is added in the binary RD/binary PR system or binary WS connected with the
binary RD. The number indicative of a multivalue image is added in the
case of the multivalue RD/multivalue PR system or multivalue WS connected
with the multivalue RD. The binary image or multivalue image is stored
into a data area 50 in accordance with the data ID 49. Binary image or
multivalue image is stored into the data area 50.
The operation of the foregoing embodiment will now be described in
accordance with document edition flowcharts shown in FIGS. 12(1) and
12(2).
First, in step S1, the binary image from the binary RD, the multivalue
image from the multivalue RD, document, figure, table, graph, binary
image, or the multivalue image stored in the HD, multivalue image from the
camera input device or VTR, integrated document of them, or white paper is
selected and displayed. In the next step S2, the processing routine is
branched to the following processes on the basis of the kinds of documents
displayed and the designated command. The processes include: a printing
process S4; a document input editing S6; a figure edition S8; a table
editing S10; a formation of a graph S12; binary image editing S15; a
multivalue image editing S19; a cut-out of data S22; and a synthesis of
data S24.
When the binary/multivalue conversion is designated for the binary image,
the binary image is converted into the multivalue image in step S16 and
the multivalue image editing in step S19 is executed.
On the other hand, when the multivalue/binary conversion is designated for
the multivalue image, the multivalue image is converted into the binary
image in step S20. The binary image editing in step S15 is executed.
In the binary image edition, figures, characters, etc. are cut-out and the
cut-out portions can be enlarged, reduced, rotated, moved, and
synthesized. In the multivalue image editing, the gradation conversion,
edge emphasis, cut-out of a target image data, and the like can be
performed in addition to those image processes.
When the document editing has been completed in step S25, the document is
written in step S26 and printed out, displayed, and stored in a hard disk
or the like. Then, this flow is finished.
In the image processing system having the foregoing constitution, a
document as shown in FIG. 13 can be displayed and edited in the multivalue
WS 7-1, 7-2, . . . , 8-1, 8-2, . . . in FIG. 1. In FIG. 13, reference
numeral 60 denotes an integrated document including a document 61, a FIG.
62, a graph 63, a table 66, a multivalue image 64 such as a photograph or
the like, and a binary image 65 such as a figure or the like. Numeral 67
denotes a display area to instruct editing commands which differ in
dependence on the editing state.
The document 61, FIG. 62, graph 63, and table 66 are developed as bits in
the binary BUF 52 in FIG. 8 from the code data, respectively. The binary
image 65 is thinned out by the variable magnification function of the BMU
18 in FIG. 5 and transferred to the same binary BUF 52. On the other hand,
the multivalue image 64 is transferred to the multivalue BUF 53 in FIG. 8
by the function of the BMU 18. Desired image data is read out of the
multivalue BUF 53 and multiplexed and displayed on the CRT display 16 in
FIG. 5.
Further, a video signal from the TV camera is input by use of a display
pattern as shown in FIG. 14 in step S1. Namely, for example, when the
integrated document 60 is displayed, a monitor screen 73 is displayed over
it.
This function can be realized by repeatedly writing input video signals
from the TV camera input device 68 into the portion corresponding to the
monitor screen of the multivalue BUF 53. Commands 74 are displayed to
remote control the TV camera input device 68 in the multivalue WS 8-2. The
display content is as shown in, e.g., FIG. 15. Commands of brightness,
contrast, focus, zoom, stop, shutter, and UP, DOWN, LEFT, and RIGHT of the
tilting base of the TV camera are displayed. When the brightness or
contrast is designated in this case, its value is sent to the TV camera
input device 68.
On the other hand, with respect to the focus, zoom, and stop, while the
corresponding portions of FAR, NEAR, TELE, WIDE, OPEN, and CLOSE are
respectively continuously designated, these commands are continuously sent
to perform the designated adjustments.
The adjustments are also similarly performed with regard to UP, DOWN, LEFT,
and RIGHT.
When the shutter is designated, the monitor is stopped and the data in the
multivalue BUF 53 at that time is specified as input data.
A multivalue image is edited hereinbelow in a manner similar to the above.
Although the image processing system coupled by a network has been
described in the above embodiment, the invention is not limited to this
constitution. A part of the system may be omitted or modified. The
invention can be also realized in a single apparatus.
Since the image processing system of the invention has been constituted as
described above, it is possible to provide an image processing system
having a high generality in which even a stereoscopic object photographed
by a video camera or the like can be also soon interposed and edited as a
photograph into a document.
As described in detail above, since the image processing system of the
invention has been constituted, even in an image processing system for
processing an image by multivalue image data, binary image data can be
image processed and an image processing system having a high generality
can be provided.
As described in detail above, since the image processing system of the
invention has been constituted, it is possible to provide an image
processing system having a high generality in which image processes can be
performed even by binary image data, multivalue image data, and their
multiplexed image data.
The invention can be also applied to another embodiment which is
constituted in a manner such that data indicative of the attribute of a
terminal connected to the system, for example, with respect to whether the
terminal is the WS for processing binary data, WS for processing
multivalue data, binary RD/PR system, multivalue RD/PR system, or the like
is properly constructed as an attribute file into the FS or memory of each
WS, and the attribute on the transmission side and the attribute on the
reception side are compared and the data is converted so as to always
reduce the time which is occupied by the data on the LAN 12 or data bus.
FIG. 16 shows a flowchart for explaining the foregoing processes. An
explanation will now be described on the basis of a constitution such that
the FS for management controls the whole system. However, the invention is
not limited to this constitution. First, when the power supply is turned
on, the attribute file is initialized (step S1). The attribute data of all
of the (n) terminals is set into the attribute file (steps S2 and S3). In
the next step S4, a check is made to see if a data transfer has been
requested or not. If NO, for example, the image editing or the like is
performed in each terminal and the attribute file is updated in accordance
with this process (step S5).
If the data transfer has been requested in step S4, the attributes on the
transmission and reception sides are compared. Only the case of
multivalue/binary will be explained here. A check is made to see if the
transmission side is the terminal to process binary data and the reception
side is also the same terminal, or the transmission side is the terminal
to process multivalue data and the reception side is also the same
terminal (type 1), or the transmission side is the terminal to process
binary data and the reception side is the terminal to process multivalue
data (type 2), or the transmission side is the terminal to process
multivalue data and the reception side is the terminal to process binary
data (type 3) (step S6). If the type 2 has been determined in step S6, the
binary data is directly transferred and at the terminal for processing the
multivalue data on the reception side, the binary data is converted into
the multivalue data by the binary/multivalue CV 33 in FIGS. 5 and 6 which
have already been described. In the case of the type 3, the multivalue
data is converted into the binary data on the transmission side in order
to reduce the transfer load on the LAN and data bus and transferred to the
terminal for processing the binary data on the reception side. In the case
of this embodiment, the multivalue/binary CV 21 which has been described
in FIGS. 2 and 3 is provided in FIG. 5 or 6.
