BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an image data supervising system used in
an image data processing apparatus in which image data derived from an
electronic still camera, a video camera and the like are converted into
magnetic signals or electric signals, and thereafter recorded on a
recording medium for storage.
2. Description of the Related Art
Very recently, electronic still cameras, video cameras and the like have
been proposed so as to acquire image data. These appliances employ either
magnetic recording mediums such as video floppy disks and video tapes, or
electronic recording mediums such as semiconductor memories.
In the electronic still cameras, video cameras, and the like for converting
the image data into the corresponding magnetic signals or corresponding
electric signals to be recorded on the recording mediums, no definite
confirmation can be made as to what image data have been recorded on the
recording mediums unless these image data are reproduced on a television
monitor, or the like.
Under such a circumstance, the more the quantity of the recorded recording
mediums increases, the more the recording medium supervision becomes
complex. Thus, cumbersome operations are necessarily required. In specific
cases, a large quantity of searching time is needed in order to search a
desirable image from the recording medium.
On the other hand, a strong demand is made such that a certain message or
the like is additionally applied to the image data which have been
produced by operating the electronic still cameras, video cameras, and the
like.
To this end, in the conventional floppy disk type electronic still cameras,
a queue track for recording the supervising data is additionally provided
on the entire recording area of the floppy disk in addition to the image
recording track region thereof.
Since, however, the recording capacity of the above-described queue track
is rather small as compared with that of the recording track region, any
messages for a plurality of image data which have been recorded on the
recording track region cannot be recorded on the queue track.
In, on the other hand, the conventional video cameras, the superimposing
function capable of superimposing such messages on the recorded image
information is specifically provided on some types of video cameras.
However, such video cameras equipped with the superimposing function have
the following drawbacks. That is, as the image data are recorded on the
recording medium under the condition that the messages have been
superimposed, no new message can be inserted into these image data once
the photographing operation by the video camera is completed. In addition,
the messages which have been superimposed during the photographing
operation cannot be deleted, or changed into other messages.
SUMMARY OF THE INVENTION
The present invention has been made in an attempt to solve the
above-described problems of the conventional image data processing
apparatus, and therefore, an object of the invention is to provide an
image data supervising apparatus in an image data processing apparatus
capable of readily supervising image data which have been recorded by
electronic still cameras, video cameras, and the like, or a recording
medium on which these image data have been recorded.
To achieve the above-described object of the invention, an image data
recording apparatus comprises:
a housing;
image signal producing means provided in said housing, for producing an
electric image signal from an optical image of an object to be imaged;
recording means provided in said housing, for recording the electric image
signal produced by said image signal producing means on a recording medium
detachably stored in said housing;
a case detachably stored in said housing;
data input means provided in one of said housing and said case, for
inputting at least information data and identification data for
identifying said recording medium;
memory means provided in said case, for storing at least said information
data and said identification data input from said data input means; and,
memory control means provided in one of said housing and said case, for
controlling a read/write operation of said memory means, and for
processing said information data and said identification data, as a single
piece of data having a relationship between said information data and
identification data.
With the above-described arrangement, there are particular advantages of
the present invention that either the image data which have been recorded
by electronic still cameras, video cameras, or the like, or the contents
of the recording mediums on which these image data have been recorded can
be readily confirmed without reproducing these data on the television
monitor, or the like.
Furthermore, the messages for the image data which have been recorded by
electronic still cameras, video cameras, or the like can be recorded and
stored, and also the messages once inputted in the image data can be
easily and simply deleted, or changed by other messages, according to the
image data supervising apparatus of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Construction Of First Electronic Still Camera System
Referring now to FIGS. 1 to 8, a construction of an electronic still camera
system according to a first preferred embodiment of the present invention
will be described.
First, FIGS. 1 through 3 represent a photographing apparatus or machine 11,
a reproducing machine 12 and a data supervising unit 13 which comprise the
electronic still camera system.
A construction of the photographing machine 11 shown in FIG. 1 will be
first of all explained. A finder 14 and a supervising unit mounting
section 15 are provided on a rear surface of the photographing machine 11.
The supervising unit mounting section 15 is so constructed that the
above-described data supervising unit 13 is detachably mounted thereon,
and includes a connector 16 for electrically connecting an electronic
circuit (will be discussed later) provided within the photographing
machine 11 and the data supervising unit 13 when the data supervising unit
13 is mounted thereon.
A release switch 17 is provided on an upper surface of the photographing
machine 11 and a lens 18 is mounted on a front surface thereof.
A magnetic recording apparatus 19 is provided within a left side section of
the photographing machine 11. A rear surface of the left side section of
the photographing machine 11 is formed as a pivotal cover 20 which is
pivotally journalled with respect to a bottom surface section. When this
pivotal cover 20 is rotated toward the rear side surface, a video floppy
disk 21 can be inserted into the photographing machine 11 and also ejected
therefrom.
In the reproducing machine 12 shown in FIG. 2, there are formed an FD
(floppy disk) inserting section 22 at the front surface thereof, into
which the floppy disk 21 on which the still image data has been recorded
by the photographing machine 11 is inserted. Under the FD inserting
section 22, there are provided operation keys for controlling various
operations of a floppy disk reproducing device (not shown in detail), such
as a rewind key 23, a fast forward key 24, a reproduction key 25, a stop
key 26 and an eject key 27. At a right side of the FD inserting unit 22, a
supervising unit mounting unit 28 on which the above-described data
supervising unit 13 can be detachably mounted is formed. This supervising
unit mounting unit 28 has the same construction as the above-described
photographing machine 11 and includes a connector 29. When the data
supervising unit 13 is mounted, an electronic circuit (will be discussed
later) provided within the reproducing machine 12 is electrically
connected to the data supervising unit 13 by this connector 29.
In the data supervising unit 13 as illustrated in FIG. 3, there are
provided a key input unit 30 and a display unit 31 capable of displaying
either data or time entered by this key input unit 30. On this key input
unit 30, there are provided a numeral key 32, a character input key 33 and
various function keys 34 to 43. As the function keys 34 to 43, there are
employed a shutter key 34 for setting a shutter speed and diaphragm key 35
for setting a diaphragm value of the photographing machine 11 when the
data supervising unit 13 is mounted on this photographing machine 11. As
further function keys, a DISK key 36 and a TRACK key 37 are operated while
this data supervising unit 13 is mounted on either the photographing
machine 11 or reproducing machine 12. These function keys 36 and 37 are
utilized when the disk numbers and track numbers of the respective floppy
disks are designated, or when the data is retrieved by utilizing the disk
number and track number. A memory key 38 is used to input the message data
with respect to the image data which has been recorded on the floppy disk
21, whereas a transfer key 39 is used for superimposing the
above-described message data on the image to be reproduced when the data
supervising unit 13 is mounted on the reproducing machine 12. In addition,
a cursor key 40 is used to instruct movements of the cursor displayed on
the display unit 31 when entering the data by means of the numeral key 32
and character input key 33, and also to instruct the recording track or
reproducing track when the data supervising unit 13 is mounted on the
photographing machine 11 or reproducing machine 12.
A DATE key 42 is utilized to input as date data the data which has been
input by the numeral key 32. A mode key 43 is to set a mode of this data
supervising unit 13 for switching between a single mode in which the data
process and the like are performed by only the data supervising unit 13,
and a cooperation mode in which the data process and the like are executed
by the photographing machine 11 in conjunction with the reproducing
machine 12.
In the electronic still camera system comprising the above-described
photographing machine 11, reproducing machine 12, and data supervising
unit 13, the still image data is recorded while the data supervising unit
13 is mounted on the photographing machine 11, and also reproduced while
the data supervising unit 13 is mounted on the reproducing machine 12.
The functions of the data supervising unit 13 are to control the shutter
speed, the diaphragm, the recording track of the floppy disk and the like
with respect to the photographing machine 11 when mounted on this
photographing machine 11, and also to supervise the recording of the disk
number, track number, and message data input by the various keys for every
recorded still image data. Furthermore, when the data supervising unit 13
is mounted to reproducing machine 12, this unit 13 controls the
reproducing track, or the like of this reproducing machine 12, to identify
the floppy disk which has been inserted into the reproducing machine 12,
and to transfer the message data which should be superimposed to the image
to be reproduced.
Arrangements Of Photographing/Reproducing Machines And Data Supervising
Unit
The internal circuit arrangements of the above-described photographing
machine 11 and reproducing 12, and also the data supervising unit 13 will
now be described.
In FIG. 4, there are shown internal arrangements of the photographing
machine 11 and data supervising unit 13.
In the photographing machine 11, a photographing operation control unit 44
is provided so as to control overall operations of the photographing
machine 11.
A photographing unit 45 controlled by the photographing operation control
unit 44 is provided in the photographing machine 11. The photographing
unit 45 comprises an optical system 46 having a lens, a diaphragm and the
like, a shutter 47, and an image sensor 48 which comprises a solid-state
imaging system such as a CCD (charge-coupled device). In the optical
system 46, a lense position, and a diaphragm open degree are set in
response to a control signal derived from the above-described
photographing operation control unit 44. The opening-time period of the
shutter 47 is under the control of the photographing operation control
unit 44. The image sensor 48 is driven under the control of the
photographing operation control unit 44 so as to produce an electric
signal (referred to as "a video, or picture signal" hereinafter) in
response to an object image which is focused thereon via the optical
system 46 and shutter 48. This video signal from the image signal is
output to a video signal processing unit 49.
The video signal processing unit 49 processes the video signal output from
the image sensor 48 in response to the control signal derived from the
control unit 44 in order to produce an (Y+S) signal containing a luminance
signal and a synchronization signal, and also color difference signals
(R-Y) and (B-Y). After these signals have been frequency-modulated and
then synthesized with each other, the resultant synthesized signal is
output to a magnetic recording signal processing unit 50 by this video
signal processing unit 49.
The magnetic recording signal processing unit 50 outputs the synthesized
signal derived from the video signal processing unit 49 as the magnetic
recording signal to a magnetic head 51 of a magnetic recording device 51.
Into the magnetic recording signal processing unit 50, an ID
(identification) data such as disk number data derived from the control
unit 44 is supplied, and is also output as the above-described magnetic
recording signal to the magnetic head 51.
In response to the magnetic recording signal furnished from the magnetic
recording signal processing unit 50, the magnetic head 51 enables both the
image data and ID data to be recorded on the floppy disk 21. The relative
position of this magnetic head 51 with respect to the floppy disk 21 is
under control of the magnetic head position control unit 52 in order that
the data are recorded on a predetermined track of the floppy disk 21.
It should be noted that the magnetic head position control unit 52 moves
the magnetic head 51 in response to a control signal supplied from the
photographing operation control unit 44.
A single recording track capacity of the floppy disk 21 is equal to 1-field
image data of the NTSC (National Television System Comittee) type color
television signal. The floppy disk 21 contains 50 tracks for recording the
image data and 1 queue track for recording the ID data such as disk number
and the like.
Also connected to the photographing operation control unit 44, are a
release switch 17, a light measuring unit 53, a distance measuring unit
54, a memory unit 55 and a timer unit 56.
The release switch 17 includes a first switch 17a and a second switch 17b.
The first switch 17a is turned on when the release switch 17 is operated
over a half push travel and the second switch 17b is turned on when the
release switch 17 is operated over a full push travel.
The light measuring unit 53 senses the brightness of the incoming light and
outputs the sensing signal to the photographing operation control unit 44.
The function of the distance measuring unit 54 is to measure a distance
from this distance measuring unit 54 to the object to be image (not shown
in detail).
The memory unit 55 receives the data such as the shutter speeds and other
data which have been key-input in the data supervising unit 13, and then
input via the photographing operation control unit 44.
The control operations of the photographing unit 44 are as follows. In
response to the ON signal of the first switch 17a produced when the
release switch 17 is operated over a half push travel, the photographing
operation control unit 44 controls the lens position of the optical system
46 based upon the data derived from the distance measuring unit 54, and
also controls the diaphragm opening degree of the optical system 46 based
upon either the diaphragm value data, or the data supplied from the light
measuring unit 53 which has been stored in the memory unit 55.
Furthermore, the photographing operation control unit 44 drives the shutter
47 based upon either the data output from the light measuring unit 53, or
the shutter speed data which have been stored in the memory unit 55 in
response to the on-signal of the second switch 17b produced when the
release switch 17 is operated over a full push travel.
The timer unit 56 continuously counts seconds, minutes, hours, days, months
and years. The resultant date data are output via the photographing
operation control unit 44 to a data supervising unit 13 in response to the
on-signal produced when the release switch 17 is pushed over a full travel
distance.
A connector 57 connectable to another connector 16 of the photographing
machine 11 is provided on the data supervising unit 13. Thus the data
supervising unit 13 is electrically connected to the photographing machine
11 by way of this connector 57. Also to this connector 57, a data
supervising control unit 58 is connected.
The key input unit 30, a display unit 31, an address supervising unit 59,
and a data memory unit 60 are connected to the data supervising control
unit 58.
The address supervising unit 59 includes a number memory 61 for storing
track numbers and disk numbers, and also an address memory unit 62 for
storing a read/write address for the data memory unit 60 corresponding to
the respective track number stored in this number memory 61.
A data memory unit 60 stores either the data which have been supplied from
the photographing machine 11 and reproducing machine 12, or the data which
have been input from the key input unit 30 in response to the control by
the data supervising control unit 58.
The functions of the data supervising control unit 58 are to output either
the data input from the key input unit 30, or the data stored in the data
memory unit 60 to either the photographing machine 11 or reproducing
machine 12, and to receive or fetch the data from the photographing
machine 11 and reproducing machine 12 under the control of either the
photographing machine 11 or reproducing machine 12.
Internal Arrangement Of Reproducing Machine
Referring now to FIG. 5, an internal arrangement of the reproducing machine
12 will be described.
Overall operations of the reproducing machine 12 are under control of a
reproducing operation control unit 63.
The reproducing operation control unit 63 outputs various control signals
in response to signals supplied from the operation keys 23 to 27 and a
data supervising unit 13.
The reproducing machine 12 is equipped with a magnetic reproducing device
64. The magnetic reproducing device 64 includes a magnetic head which is
exclusively used for reproducing the data which has been recorded on the
floppy disk 21. The relative position of this magnetic head 65 to the
floppy disk 21 is controlled by a magnetic head position control unit 66
which is operated based upon the control of the reproducing operation
control unit 63. The magnetic head 65 reads out the data recorded on a
predetermined track of the floppy disk 21.
The data signal read out from the floppy disk 21 by way of the magnetic
head 65 is supplied to a magnetic recording signal processing unit 67.
This magnetic recording signal processing unit 67 amplifies the data
signal supplied from the magnetic head 65, outputs the image data to the
video signal processing unit 68 when the amplified data signal corresponds
to the image data, and also outputs the ID data to the reproducing
operation control unit 63 when the amplified data signal corresponds to
the ID data.
The functions of the video signal processing unit 68 are to separate the
video signal which has been supplied thereto from the magnetic recording
signal processing unit 67 into the synthesized signal (Y+S) containing the
luminance signal and synchronization signal and also color difference
signals (R-Y) and (B-Y), and thereafter frequency-demodulates these
separated signals. Furthermore, the FM-demodulated signals are converted
into the NTSC signal and then the resultant NTSC signal is output to the
superimposing circuit 69.
The superimposes circuit 69 superimpose the message data output from the
reproducing operation control unit 63 on the NTSC color television signal
supplied from the video signal processing unit 68 to produce an image
signal. This image signal is then output to the video signal output
terminal.
A memory unit 70 is connected to the reproducing operation control unit 63.
In this memory unit 70, a track No. memory 71 and a memorandum data memory
72 are provided. The track No. data output from the data supervising unit
13 and either the message data corresponding to the track No., or timer
data are supplied via the reproducing operation unit 63 to the memory unit
70 for the writing purpose.
Electronic Still Camera Operation
The operation of the above-described electronic still camera according to
the first preferred embodiment will now be described.
First, an operation to photograph an object to be imaged will be described,
utilizing the photographing machine 11.
The data supervising unit 13 is mounted on the supervising unit mounting
unit 15 of the photographing machine 11 and then this data supervising
unit 13 is set to the cooperation mode for photographing the object. FIG.
6 is a flowchart for explaining various operations of the photographing
machine 11 under the above-described conditions.
Under these circumstances, in case that a user wants to set a specific
shutter speed, or a diaphragm value, the numeral keys 32 and either the
shutter key 34 or diaphragm key 35 provided on the data supervising unit
13 are operated so as to input either a desired shutter speed or diaphragm
value. Thus, either the entered shutter speed data, or diaphragm value
data is transferred via the data supervising control unit 58 in the data
supervising unit 13 to the photographing operation control unit 44 and
stored into the memory unit 55 (steps S1, S2, and S3).
When a still picture is recorded on a predetermined track of the floppy
disk 21, a disk number is designated by manipulating the numeral key 32
and track key 37 in the data supervising unit 13. The above-described
designated track number data is stored via the data supervising control
unit 58 and photographing operation unit 44 to the memory unit 55 (steps
S1 and S4).
It should be noted that when the track number is not designated in the data
supervising unit 13, a first track (for instance, 1 track in case of an
used disk) of empty tracks (namely tracks on which no still pic | | |
