`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
`15 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(cid:173)
`tion of the recording of the image data or 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
`data or the sound data to be recorded in the
`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(cid:173)
`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(cid:173)
`rangement, it is extremely difficult to reduce the
`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(cid:173)
`tion data indicative of reading
`information data,
`stored in the management data recording area,
`
`Background of the Invention:
`
`Field of the Invention:
`
`The present invention relates to an information
`signal processing apparatus for processing an in(cid:173)
`formation signal and, more particularly, to an in(cid:173)
`formation signal processing apparatus for recording
`an information signal in a recording medium.
`
`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(cid:173)
`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(cid:173)
`ranged to record the image signals or the sound
`signals on the recording tracks formed on the mag(cid:173)
`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(cid:173)
`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.
`In contrast, a hard disk unit is known as a
`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(cid:173)
`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, it is possible to construct comparatively
`inexpensively a system having a large storage ca(cid:173)
`pacity.
`Various kinds of hard disk units are provided
`for various specifications such as recording capac(cid:173)
`ity, weight, power consumption and
`recording
`speed. If the system is constructed so that plural
`kinds of hard disk units can be attached, it is

`
`indicative of the state of use of each cluster, re(cid:173)
`cording the read information data in the manage(cid:173)
`ment data recording area, and restarting the opera(cid:173)
`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(cid:173)
`ably while image data corresponding to a plurality
`of images or sound data corresponding to a long(cid:173)
`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(cid:173)
`ing medium in units of one data file and transmitted
`to an external device, such as an external com(cid:173)
`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
`data files recorded in the recording medium is
`handled as an independent file.
`To prevent a wrong data file from being errone(cid:173)
`ously read out together with a desired file recorded
`in the recording medium or to prevent a wrong
`data file from being erroneously erased during era(cid:173)
`sure of a desired file recorded in the recording
`medium, it is necessary to individually add a dis(cid:173)
`crimination number to each data file during record(cid:173)
`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(cid:173)
`ber corresponding to the stored number or re(cid:173)
`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(cid:173)
`tery replacement, the number of recorded photo(cid:173)
`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(cid:173)
`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(cid:173)
`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, a non(cid:173)
`volatile memory may be provided in the system
`body so that the counted number of recorded pho(cid:173)
`tographic pictures is stored in the nonvolatile mem(cid:173)
`ory during photographing and recording operations.
`With this arrangement, if 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(cid:173)
`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 if 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(cid:173)
`ory, data about the number of recorded photo(cid:173)
`graphic pictures is not correctly updated. As a
`result, a discrimination number identical to a dis(cid:173)
`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(cid:173)
`ready used discrimination number.
`The above-described system is also arranged
`in the following manner. If a digitized image signal
`(i.e., image data) or a digitized sound signal (i.e.,
`sound data) are to be recorded in a recording
`medium such as a memory card or a hard disk
`unit, after the image data or the sound data is
`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.
`During photographing and recording operations, if
`the storage capacity of the image memory is filled
`with the image data or the sound data stored in the
`image memory once, the photographing and re(cid:173)
`cording operations are interrupted once and the
`image data or the sound data stored in the image

`
`memory is transmitted to and recorded in the re(cid:173)
`cording medium. Thus, if a storage capacity ca(cid:173)
`pable of storing the image data or the sound data
`occurs in the storage capacity of the image mem(cid:173)
`ory, the system is placed in the state of being able
`to restart the photographing and recording oper(cid:173)
`ations.
`the case of the electronic still
`in
`However,
`camera having the above-described arrangement,
`an operator cannot make a judgement as to wheth(cid:173)
`er the photographing and recording operations are
`interrupted because the storage capacity of the
`image memory is full or the photographing and
`recording operations can be performed because
`the storage capacity of the image memory contains
`a data storable portion. Such an electronic still
`camera, therefore, involves the following operation(cid:173)
`al disadvantages. For example, if the operator op(cid:173)
`erates a recording start instructing switch to con(cid:173)
`tinue the photographing and recording operations,
`it may be impossible to start the photographing
`and recording operations. If the operator operates
`the recording start instructing switch during an in(cid:173)
`terruption of the photographing and recording oper(cid:173)
`ations and the recording start 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(cid:173)
`dium. It is particularly difficult for the operator to
`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(cid:173)
`ventionally been realized as an apparatus capable
`of recording and reproducing still image data and
`sound data in a recording medium using a mag(cid:173)
`netic disk called a still video floppy disk. An elec(cid:173)
`tronic still camera is also proposed which uses a
`memory card including a solid-state memory ele(cid:173)
`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(cid:173)
`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
`file, the image files and the sound files are com(cid:173)
`bined so that reproduction or transmission can be
`performed.
`However, in the case of the conventional elec(cid:173)
`tronic still camera, 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
`files so that reproduction or transmission can be
`performed.

`
`Summary of the Invention:
`
`It is, therefore, an object of the present inven(cid:173)
`tion to an information signal processing apparatus
`capable of solving the above-described problems.
`Another object of the present invention is to
`provide an information signal processing apparatus
`which is capable of recording an information signal

`signal, temporarily storing therein the input infor(cid:173)
`mation signal and storing therein management in(cid:173)

`information signals to be recorded in a recording
`medium in predetermined units is to be added to
`the information signal, so that the information signal
`can be recorded in the recording medium with
`correct discrimination information added to the in-
`formation signal. In such an information signal pro(cid:173)

`out the information signal recorded in the recording
`medium in the predetermined units so that the read
`information signal can be erased or subjected to
`various processings in the external device.
