`
`
`
`
`
`The present invention relates to an information
`
`
`
`
`
`
`
`
`
`
`
`
`
`signal processing apparatus for processing an in-
`formation signal and, more particularly,
`to an in-

`
`
`Description of the Related Art:
`
`
`
`
`
`
`
`
`
`
`
`
`
`An electronic still video system has heretofore
`been known as one example of an information
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`signal processing apparatus for processing an in-
`formation signal. The electronic still video system
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`is arranged to record information signals, such as
`image signals or sound signals, on a plurality of
`
`
`
`
`
`
`
`
`
`concentric recording tracks which are formed on a
`
`
`
`
`
`
`
`
`magnetic disk, and to select an arbitrary recording
`
`
`
`
`
`
`
`
`track from among the recording tracks formed on
`
`
`
`
`
`
`
`
`the magnetic disk and reproduce the information
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`signal, such as the image signal or
`the sound
`signal, recorded on the selected recording track.
`
`
`
`
`
`
`
`Such an electronic still video system is ar-
`
`
`
`
`
`
`
`ranged to record the image signals or the sound
`
`
`
`
`
`
`
`
`
`signals on the recording tracks formed on the mag-
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`netic disk,
`in the state of analog signals. However,
`a new system has recently been proposed which is
`
`
`
`
`
`
`
`
`
`arranged to store digitized image signals or sound
`
`
`
`
`
`
`
`
`signals in a memory card including a plurality of
`
`
`
`
`
`
`
`
`
`RAMS (random access memories) made from
`
`
`
`
`
`
`semiconductor memory elements such as D-RAMs,
`
`
`
`
`
`
`S—RAMs or EEP~ROMs.
`
`
`
`
`
`
`
`
`
`However, the storage capacity of the memory
`card is limited because of the limited storage ca-
`
`
`
`
`
`
`
`
`pacity per chip of the memory device or the limits
`
`
`
`
`
`
`
`
`
`
`of the number of chips of a memory element which
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`can be mounted on a single memory card. Further,
`since the memory element is more expensive than
`
`
`
`
`
`
`
`
`other recording media,
`it is presently economically
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`difficult to utilize the memory card as a recording
`medium of large storage capacity.
`
`
`
`
`
`is known as a
`In contrast, a hard disk unit
`
`
`
`
`
`
`
`
`
`
`recording medium having a larger storage capacity
`
`
`
`
`
`
`
`than the memory card, and there has recently been
`
`
`
`
`
`
`
`
`
`provided a hard disk unit which is removably at-
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`tachable to an apparatus body similarly to the
`
`
`
`
`
`
`
`
`
`
`
`memory card.
`If such a hard disk unit is used with
`
`
`
`
`
`
`
`
`an electronic still video camera as a recording
`medium,
`is possible to construct comparatively
`it
`
`
`
`
`
`
`
`inexpensively a system having a large storage ca-
`
`
`
`
`
`
`
`
`pacity.
`Various kinds of hard disk units are provided
`
`
`
`
`
`
`
`
`for various specifications such as recording capac-
`
`
`
`
`
`
`
`
`
`
`
`
`ity, weight, power consumption and recording
`speed.
`If the system is constructed so that plural
`
`
`
`
`
`
`
`
`
`kinds of hard disk units can be attached,
`is
`it
`
`
`
`
`
`
`
`
`
`
`
`
`
`possible to meet a variety of demands of users.
`
`
`
`
`
`
`
`
`
`The aforesaid system is constructed to record
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`a digitized image signal
`(i.e.,
`image data) or a
`digitized sound signal (i.e., sound data) in a record-
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`ing medium such as the memory card or the hard
`
`
`
`
`
`
`
`
`disk unit
`in the following manner. The recording
`area of the recording medium is divided into an
`
`
`
`
`
`
`
`
`
`information data recording area and a management
`
`
`
`
`
`
`
`data recording area, and the image data or the
`
`
`
`
`
`
`
`
`
`sound data is divided into units each corresponding
`
`
`
`
`
`
`
`
`to what is called "cluster". and each of the units is
`
`
`
`
`
`
`
`
`
`
`
`recorded in one cluster
`in the information data
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`recording area.
`Information data indicative of the
`state of use of each cluster is
`recorded in the
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`management data recording area.
`If image data or sound data is to be recorded
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`over a plurality of clusters, during recording of the
`image data or the sound data, while the position of
`
`
`
`
`
`
`
`
`
`
`a cluster in which the image data or the sound data
`
`
`
`
`
`
`
`
`
`
`
`is recorded is being stored in a management data
`
`
`
`
`
`
`
`
`
`memory provided in a system control circuit, the
`
`
`
`
`
`
`
`
`image data or the sound data is recorded in the
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`information data recording area. After the comple—
`the recording of
`the image data or
`tion of
`the
`
`
`
`
`
`
`
`
`
`
`sound data,
`the information data indicative of the
`
`
`
`
`
`
`
`
`state of use of each cluster, which is stored in the
`
`
`
`
`
`
`
`
`
`
`
`management data memory provided in the system
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`control circuit,
`is recorded in the management data
`recording area.
`
`
`However,
`if the amount of data of the image
`
`
`
`
`
`
`
`
`
`the sound data to be recorded in the
`data or
`
`
`
`
`
`
`
`
`
`
`recording medium is increased and the number of
`
`
`
`
`
`
`
`
`clusters used for recording the image data or the
`
`
`
`
`
`
`
`
`
`sound data is increased for the purpose of record
`
`
`
`
`
`
`
`
`ing high-quality-image data or high-quality-sound
`
`
`
`
`
`data, it is necessary to provide a management data
`
`
`
`
`
`
`
`
`
`memory of large storage capacity within the sys—
`
`
`
`
`
`
`
`tem control circuit so that the positions of clusters
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`used for recording the image data or the sound
`data can be stored during the recording of
`the
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`image data or the sound data. With such an ar-
`
`
`
`
`
`
`
`
`rangement,
`is extremely difficult
`to reduce the
`it
`size, weight and cost of the apparatus.
`
`
`
`
`
`
`
`On the other hand,
`if a memory of small stor-
`
`
`
`
`
`
`
`
`
`age capacity is used as the management data
`
`
`
`
`
`
`
`
`memory provided within the system control circuit,
`
`
`
`
`
`
`
`the size, weight and cost of the system can be
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`reduced. However, the management data memory
`of small storage capacity does not have a sufficient
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`storage capacity to store the positions of clusters
`used during recording of
`the image data or the
`
`
`
`
`
`
`
`
`
`sound data. Accordingly,
`the management data
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`memory of small storage capacity needs to repeat
`the processing of stopping once the operation of
`
`
`
`
`
`
`
`
`recording the image data or the sound data in the
`
`
`
`
`

`information data recording area, reading informa—
`tion data indicative of

`
`indicative of the state of use of each cluster, re-
`
`
`
`
`
`
`
`
`
`cording the read information data in the manage-
`

`tion of recording the image data or the sound data

`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`in the information data recording area. As a result,
`
`
`
`
`
`
`
`
`
`
`there is the problem that the speed of recording of
`the image data or the sound data lowers remark-
`
`
`
`
`
`
`
`
`ably while image data corresponding to a plurality
`
`
`
`
`
`
`
`of images or sound data corresponding to a long-
`
`
`
`
`
`
`
`
`time sound is being continuously recorded.
`
`
`
`
`
`
`The data files of the image data or the sound
`
`
`
`
`
`
`
`
`
`
`data which are recorded in the recording medium,
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`such as a memory card or a hard disk unit,
`in the
`above-described manner, are read from the record-
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`ing medium in units of one data file and transmitted
`
`
`
`
`
`
`
`
`to an external device, such as an external com—
`puter, a printer and a data transmission device.
`In
`
`
`
`
`
`
`
`
`
`the external device, various processing such as
`
`
`
`
`
`
`
`operational processing, printing processing or data
`
`
`
`
`
`
`transmission processing is performed. Each of the
`
`
`
`
`
`
`
`recorded in the recording medium is
`data files
`
`
`
`
`
`
`
`
`handled as an independent file.
`
`
`
`
`
`
`
`
`
`
`
`
`
`To prevent a wrong data file from being errone—
`ously read out together with a desired tile recorded
`
`
`
`
`
`
`
`
`
`in the recording medium or to prevent a wrong
`
`
`
`
`
`
`
`
`
`data file from being erroneously erased during era-
`
`
`
`
`
`
`
`sure of a desired file recorded in the recording
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`medium,
`it
`is necessary to individually add a dis-
`crimination number to each data tile during record-
`
`
`
`
`
`
`
`ing of the data files in the recording medium so
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`that each of the data files can be identified. For
`example, a system which records image data files
`
`
`
`
`
`
`
`
`in the recording medium is arranged to count the
`
`
`
`
`
`
`
`
`
`number of photographic pictures recorded during
`
`
`
`
`
`
`photographing and recording operations, store the
`
`
`
`
`
`
`counted number of recorded photographic pictures
`
`
`
`
`
`
`in a system body, generates a discrimination num—
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`re-
`ber corresponding to the stored number or
`
`
`
`
`
`
`corded photographic pictures, add the generated
`discrimination number to an obtained image data
`
`
`
`
`
`
`
`file, and record the image data file in the recording
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`medium together with the generated discrimination
`number.
`
`Since the above-described electronic still video
`
`
`
`
`
`
`camera is a portable device, a supply of electric
`
`
`
`
`
`
`
`
`
`power depends on a battery and,
`if the remaining
`
`
`
`
`
`
`
`
`
`amount of battery power becomes less during
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`photographing and recording,
`it will be necessary
`
`
`
`
`to replace the battery.
`
`
`
`
`
`
`
`
`
`If the remaining amount of power in the battery
`provided in the system body is insufficient or the
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`battery is removed from the system body for bat-
`
`
`
`
`
`
`tery replacement,
`the number of recorded photo—
`graphic pictures which has been stored in the
`
`
`
`
`
`
`
`
`system body in the above-described manner will
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`be reset. If photographing and recording operations
`are executed after the battery replacement, a dis-
`
`
`
`
`
`
`
`crimination number
`identical
`to a discrimination
`
`
`
`
`
`
`
`
`number which is already added to an image data
`
`
`
`
`
`
`
`
`
`file recorded in the recording medium is added to a
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`new image data file, and the new image data file is
`recorded together with the already used discrimina-
`
`
`
`
`
`
`
`
`
`
`
`
`
`tion number. When a predetermined image data
`
`
`
`
`
`
`
`
`
`
`file recorded in the recording medium is to be read
`out and transmitted to an external device, such as
`
`
`
`
`
`
`
`
`
`an external computer, a printer and a data trans-
`
`
`
`
`
`
`
`
`mission device for the purpose of executing various
`
`
`
`
`
`
`
`
`processing such as operational processing, printing
`
`
`
`
`
`
`processing or data transmission processing in the
`
`
`
`
`
`
`
`external device, there is the problem that a wrong
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`data file is erroneously read out together with the
`desired file. Otherwise, when a predetermined data
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`file recorded in the recording medium is
`to be
`erased,
`there is the problem that a wrong file is
`
`
`
`
`
`
`
`
`
`
`erroneously erased in place of the desired file.
`
`
`
`
`
`
`
`
`To solve the above-described problems, anon-
`
`
`
`
`
`
`volatile memory may be provided in the system
`
`
`
`
`
`
`
`
`body so that the counted number of recorded pho—
`
`
`
`
`
`
`
`
`tographic pictures is stored in the nonvolatile mem-
`
`
`
`
`
`
`
`ory during photographing and recording operations.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`With this arrangement,
`it the remaining amount of
`power in the battery provided in the system body
`
`
`
`
`
`
`
`
`
`becomes insufficient or
`the battery is
`removed
`
`
`
`
`
`
`
`from the system body for battery replacement, it is
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`possible to prevent resetting of the counted num-
`
`
`
`
`
`
`
`ber of recorded photographic pictures which are
`stored in the nonvolatile memory within the system
`
`
`
`
`
`
`
`
`body in the above-described manner. However, the
`
`
`
`
`
`
`
`number of times of data rewriting of the nonvolatile
`
`
`
`
`
`
`
`
`
`memory is limited, and it the number of times of
`
`
`
`
`
`
`
`
`
`
`rewriting of data about
`the number of recorded
`
`
`
`
`
`
`
`
`photographic pictures exceeds the allowable num~
`
`
`
`
`
`ber of times of data writing of the nonvolatile mem-
`
`
`
`
`
`
`
`
`
`ory, data about
`the number of recorded photo-
`
`
`
`
`
`
`
`graphic pictures is not correctly updated. As a
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`result, a discrimination number identical
`to a dis-
`
`
`
`
`
`
`
`
`crimination number which is already added to an
`image data file recorded in the recording medium
`
`
`
`
`
`
`
`
`is added to a new image data file, and the new
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`image data file is recorded together with the al-
`ready used discrimination number.
`
`
`
`
`The above-described system is also arranged
`
`
`
`
`
`
`in the following manner.
`It a digitized image signal
`
`
`
`
`
`
`
`
`
`(i.e.,
`image data) or a digitized sound signal
`(i.e.,
`
`
`
`
`
`
`
`
`
`sound data) are to be recorded in a recording

`
`
`
`

`
`
`
`
`

`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`stored in an image memory once, the image data
`or the sound data stored in the image memory is
`
`
`
`
`

`
`
`
`
`read out and recorded in the recording medium.

`However,
`
`
`
`

`
`
`
`
`
`an operator cannot make ajudgement as to wheth-

`
`
`
`
`
`
`
`
`the storage capacity of the image memory contains
`a data storable portion. Such an electronic still
`
`
`
`
`
`
`
`
`
`
`
`
`
`camera, therefore, involves the following operation-
`al disadvantages. For example,
`if the operator op-
`
`
`
`
`
`
`
`erates a recording start
`instructing switch to con-
`
`
`
`
`

`
`
`
`
`
`
`it may be impossible to start
`the photographing

`and recording operations.
`If the operator operates

`instructing switch
`
`
`
`
`
`
`
`remains operated, the photographing and recording
`
`
`
`
`
`
`operations are restarted at an unintended timing for
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`the operator, so that unintended image data or
`sound data will be recorded in the recording me-
`
`
`
`
`
`
`
`
`dium.
`is particularly difficult for the operator to
`It
`
`
`
`
`
`
`
`
`
`make a judgement as to the timings of starting,
`
`
`
`
`
`
`
`
`
`resuming and ending of
`the photographing and
`
`
`
`
`
`
`
`recording operations during a continuous-shooting
`
`
`
`
`
`recording mode.
`
`
`
`
`
`
`
`
`
`Such an electronic still camera has also con-
`ventionally been realized as an apparatus capable
`
`
`
`
`
`
`
`of recording and reproducing still
`image data and
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`sound data in a recording medium using a mag-
`netic disk called a still video floppy disk. An elec-
`
`
`
`
`
`
`
`
`
`tronic still camera is also proposed which uses a
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`memory card including a solid-state memory ele-
`
`
`
`
`
`
`
`
`
`
`ment, such as a DRAM, an SRAM or an EEPROM,
`which is packaged in card form.
`
`
`
`
`
`
`If the still image data and the sound data are to
`
`
`
`
`
`
`
`
`
`
`
`be recorded in the recording medium described
`
`
`
`
`
`
`
`above, the still image data and the sound data are
`
`
`
`
`
`
`
`
`
`
`recorded in file form on picture-by-picture basis,
`
`
`
`
`
`
`
`
`
`
`
`
`
`and combination information indicative of a cor—
`respondence between each image file and each
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`sound file is also recorded as a control file. On the
`basis of the combination information in the control
`
`
`
`
`
`
`

`
`
`
`
`
`
`
`
`
`the image files and the sound files are com-

`
`
`
`
`
`
`
`
`bined so that reproduction or transmission can be
`performed.

`
`

`
`
`
`

`if the control file is erased, the
`correspondence between the image files and the
`
`
`
`

`
`
`sound files is lost, so that it
`is impossible to op-
`
`
`
`
`
`
`

`
`
`
`timumly combine the image files with the sound
`

`
`
`capable of solving the above—described problems.
`Another object of
`invention is to
`the present
`
`
`
`
`
`
`
`
`provide an information signal processing apparatus
`
`
`
`
`
`
`which is capable of recording an information signal
`
`
`
`
`
`
`

`
`
`
`
`
`
`
`
`
`having a large amount of information in a recording

`medium without
`lowering a recording speed and
`
`

`ac—
`To achieve the above-described objects,
`cording to one aspect of
`the present
`invention,

`
`
`
`
`there is provided an information signal processing
`
`
`
`
`
`
`
`apparatus which is arranged to record an informa-
`
`
`
`
`
`
`
`tion signal in a recording medium and which com-
`
`
`
`
`
`
`
`
`prises recording means for recording the informa-
`
`
`
`
`
`
`
`
`
`
`
`
`
`tion in the recording medium, and temporarily stor—
`ing means for receiving, as its input, an information

`
`mation signal and storing therein management in-
`
`

`
`
`formation prepared during a recording of the in-
`
`
`
`
`
`
`
`
`
`
`
`
`
`formation signal in the recording medium.
`Another object of
`the present
`invention is to
`
`
`
`
`
`
`
`
`provide an information signal processing apparatus
`
`
`
`
`
`
`of good operability which is capable of preventing
`
`
`
`
`
`
`
`
`erroneous discrimination information from being ad-
`
`

`the information signal, so that the information signal
`
`
`
`
`
`
`

`
`
`
`
`
`
`can be recorded in the recording medium with
`correct discrimination information added to the in-

`
`
`
`
`
`
`
`
`various processings in the external device.
