Description

  The present invention relates to an imaging apparatus, for example, in a camera-integrated video tape recorder, in which an imaging result is sequentially and cyclically recorded in a prescribed storage means, and an imaging result at a prescribed time immediately before recording of the imaging result is started on a recording medium. By holding in this storage means, it is possible to effectively avoid deterioration of mobility and to record without missing a valuable photographing opportunity.

  2. Description of the Related Art Conventionally, a camera-integrated video tape recorder composed of this type of imaging device is capable of so-called one-man operation, so that it can be carried to a news gathering site to record various videos, and the recorded videos can be used for news programs and the like. It is made like that.

  By the way, in such a news gathering site, a cameraman stands by holding the operation mode of the camera-integrated video tape recorder in a standby state, and when a news gathering opportunity comes, press the recording button to press the camera-integrated video tape recorder. The operation mode is switched to the recording mode, thereby recording various videos.

  Therefore, when a sudden change of a situation that cannot be predicted by the cameraman occurs, the conventional video tape recorder with an integrated camera sometimes loses a decisive video recording opportunity even if the recording button is pressed immediately. It was.

  If a sudden change in such a situation is predicted in advance, a method of keeping the camera-integrated video tape recorder in a recording state is also conceivable, but this consumes a large amount of magnetic tape and battery, and the camera-integrated There is a problem that the mobility of the video tape recorder is impaired. Another possible method is to connect a separate video tape recorder and always record video signals. However, in this case as well, there is a problem that the mobility of the camera-integrated video tape recorder is impaired.

  On the other hand, in such a case, there may be a method in which the imaging result is separately delayed and recorded on the magnetic tape via an external memory. In this case, however, the camera-integrated video tape recorder is connected to the external memory. There is a problem that mobility is impaired.

  The present invention has been made in consideration of the above points, and an imaging apparatus capable of effectively avoiding deterioration in mobility of a camera-integrated video tape recorder and recording without missing a valuable photographing opportunity. It is what we are going to propose.

  In order to solve this problem, the present invention is applied to an imaging apparatus that records an imaging result on a prescribed recording medium. Here, in the standby state, the previous imaging results are sequentially and cyclically recorded in the prescribed storage means. When this standby state is released, recording of the imaging results to the recording medium is started and the previous storage means is recorded. The recording of the imaging result is finished. Also, at this time, the previous recording medium is a magnetic tape, the previous storage means is held in a replaceable manner, and the previous imaging device compresses the imaging result and records it together with the audio signal in the previous storage means To do.

  In place of this, the imaging device records the identification signal together with the previous imaging result in the previous storage means and recording medium, and reproduces the corresponding imaging result from the storage means and recording medium based on the identification signal. Can be able to.

  By these means, in the standby state, the imaging results are sequentially and cyclically recorded in the prescribed storage means. When this standby state is released, the recording of the imaging results is started on the previous recording medium and the previous storage is performed. If the recording of the imaging result to the means is completed, the imaging result of the specified period immediately before the recording of the imaging result on the recording medium can be held in this storage means.

  Further, if the previous recording medium is a magnetic tape, the previous storage means is held in a replaceable manner, and the previous imaging device compresses the imaging result and stores it together with the audio signal in the previous storage means, The present invention can be applied to a camera-integrated video tape recorder.

  Further, if an identification signal is recorded together with the previous imaging result in the previous storage means and recording medium, and the corresponding imaging result can be reproduced from the storage means and recording medium with reference to this identification signal, editing work etc. The corresponding imaging result can be easily reproduced.

  According to the present invention, in the standby state, the imaging results are sequentially and cyclically recorded in the storage means held in a replaceable manner, and when the standby state is released, the recording of the imaging results on the recording medium is started, By ending the recording of the imaging result in the previous storage means, simply providing this storage means, and when this standby state is released, the imaging results of the immediately preceding specified period can be held in this storage means. it can. As a result, it is possible to effectively avoid the deterioration of the mobility of this type of imaging apparatus and to record without missing a valuable photographing opportunity.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

  FIG. 1 is a block diagram showing a recording system of a camera-integrated video tape recorder according to a first embodiment of the present invention. In this camera-integrated video tape recorder 1, a desired subject is imaged. The recorded video signal SV is recorded on the magnetic tape 2.

  That is, in this camera-integrated video tape recorder 1, the camera signal processing circuit 3 processes the output signal of a CCD solid-state imaging device (not shown) and outputs the video signal DV as the imaging result in the form of a digital signal. The subsequent video signal compression circuit 4 compresses and outputs the video signal DV by a prescribed data compression method. Here, this data compression method is a data compression method similar to MPEG (Moving Picture Experts Group), and has a hierarchical structure similar to MPEG, and reduces the amount of data by a method of motion compensation, quantization, and variable length coding. .

  Thus, as shown in FIG. 2, the video signal compression circuit 4 converts the 10 [bit] and 27 [MHz] video signals DV obtained from the camera signal processing circuit 3 into 4 [bit] and 6.75 [MHz]. The digital video signal DV1 is converted, and the data amount is reduced to about 1/10 and output. Note that the video signal compression circuit 4 compresses data in units of GOP (Group Of Picture), which is one of the hierarchical structures of this type of data compression technique, so that in the video tape recorder 1 with an integrated camera, the digital video signal DV1 is compressed. The original digital video signal DV can be reproduced even when is reproduced at random.

  The error correction code adding circuit 5 adds an error correction code to the digital video signal DV1 in a specified block unit, and then outputs it in a specified order. The modulation circuit 6 encodes the output data of the error correction code adding circuit 5 by an encoding method suitable for recording on the magnetic tape 2 and outputs it in the form of serial data. The rotary transformer 7 transmits the output data of the modulation circuit 6 to a recording amplification circuit 8 mounted on a rotary drum. The recording amplification circuit 8 moves a magnetic head (not shown) in response to the output data of the rotary transformer 7. As a result, recording tracks are sequentially formed on the magnetic tape 2 in an oblique manner to record the digital video signal DV.

  At this time, in the camera-integrated video tape recorder 1, the video signal DV is recorded during a specified period, during which the corresponding magnetic head scans the magnetic tape diagonally, and the remaining area of the recording track is divided. Then, the audio signal SA and the index signal ID are recorded respectively.

  That is, in the camera-integrated video tape recorder 1, an analog / digital conversion circuit (A / D) 9 performs an analog / digital conversion process on an audio signal input via a microphone or the like to generate a digital audio signal DA. The error correction code adding circuit 5 adds an error correction code to the digital audio signal DA in a predetermined block unit in addition to the digital video signal DV1, and then outputs the digital audio signal DA in a predetermined order. The modulation circuit 6 encodes the digital audio signal DA in addition to the digital video signal DV1, and outputs it in the form of serial data.

  At this time, the modulation circuit 6 outputs this serial data at a prescribed timing with reference to the scanning timing of the magnetic head, whereby the camera-integrated video tape recorder 1 divides the recording track and outputs the audio signal SA and A video signal SV is recorded.

  Further, in this camera-integrated video tape recorder 1, the rotary transformer 7 receives the index signal ID output from the system control circuit 13 through a modulation circuit (not shown) at a specified timing, and receives the audio signal SA, The index signal ID is recorded obliquely on the magnetic tape 2 instead of the video signal SV.

  On the other hand, the recording amplifier circuit 14 forms a recording track extending in the longitudinal direction of the magnetic tape 2 by driving a prescribed fixed head in accordance with the index signal ID, and records the index signal ID on this recording track. To do.

  Here, the index signal ID is output in response to the pressing operation of the recording button 15 in the camera-integrated video tape recorder 1 and is incremented by the system control circuit 13 so as to be incremented every time one scene is shot. Generated. That is, in this type of camera-integrated video tape recorder 1, the recording button 15 is repeatedly pressed to record a material of several to several hundred cuts on one magnetic tape. The editing operation is executed by selectively re-recording each material. Thus, the camera-integrated video tape recorder 1 is formed so that processing such as cueing of each material can be executed at the time of editing based on the index signal ID, thereby improving the efficiency of editing work. Has been made.

  In addition to the video signal DV and audio signal SA recording system for the magnetic tape 2, the camera-integrated video tape recorder 1 stores the video signal DV and audio signal SA immediately before recording on the magnetic tape 2 in the memory 16. Hold on.

  That is, in the camera-integrated video tape recorder 1, the rate conversion circuit 17 receives the digital video signal DV1 of 4 [bit] and 6.75 [MHz] output from the video signal compression circuit 4, and receives 16 [bit], 1 Converted to 6875 [MHz] digital video signal and output (FIG. 2). The rate conversion circuit 17 receives the digital audio signal DA output from the analog / digital conversion circuit 9 and similarly converts it into 16-bit parallel data and outputs it. Thus, the camera-integrated video tape recorder 1 can efficiently record the digital video signal DV1 and the digital audio signal DA.

  The memory 16 is formed of a memory card that is detachably held in the camera-integrated video tape recorder 1 and is address-controlled by the memory control circuit 18 to record the digital video signal DV1, the digital audio signal DA, and the index signal ID. To do. That is, as shown in FIG. 3, the memory 16 divides the memory space into a system area and a data area.

  The memory 16 further divides this data area into a plurality of recording areas AR0, AR1, AR2,..., And corresponding to each material recorded on the magnetic tape 2, a digital video signal immediately before starting recording of each material. The DV1 and the digital audio signal DA are held in each area AR0, AR1, AR2,. Here, the recording of the digital video signal DV1 and the digital audio signal DA is performed in the recording areas AR0, AR1, AR2, according to the address data issued by the memory control circuit 18, as shown by the arrow a in the standby operation mode. The digital video signal DV1 and the digital audio signal DA are sequentially and cyclically recorded in one of the... And when the recording button 15 is pressed, the recording operation is stopped and executed.

  Thus, as shown in FIG. 4, in the video tape recorder 1 with an integrated camera, the digital video signal DV1 (FIG. 4A) sequentially output from the video signal compression circuit 4 in GOP units is stored in the memory. 16 is sequentially and cyclically recorded (FIG. 4B), and when the recording button 15 is pressed at time t1, recording to the memory 16 is stopped, and the digital video signal DV1 is transferred from the subsequent GOP to the magnetic tape 2. Recording is performed (FIG. 4C). In practice, in this embodiment, these recording areas AR0, AR1, AR2,... Are formed with a memory space secured so that a digital video signal DV1 and a digital audio signal DA of several seconds to several tens of seconds can be recorded. Thus, the camera-integrated video tape recorder 1 can record the digital video signal DV1 and the digital audio signal DA for several seconds to several tens of seconds immediately before the recording is started by pressing the recording button 15.

  On the other hand, the memory 16 records management data in the system area, and records the correspondence relationship with the magnetic tape 2 by this management data. Further, the memory 16 divides the system area that follows the recording areas AR0, AR1, AR2,... Of the data area, and designates the corresponding recording areas AR0, AR1, AR2,. Address data (AR0, AR1, AR2,...), Corresponding index signals ID0, ID1, ID2,..., Head recording of digital video signal DV1 and digital audio signal DA in each recording area AR0, AR1, AR2,. Address data ADm + 1, ADn + 1, ADo + 1,... For designating the position are recorded.

  Thus, the memory control circuit 18 is controlled by the system control circuit 13 to switch the operation, and issues address data to the memory 16 to control the operation of the memory 16. The system control circuit 13 is formed by a microcomputer that controls the operation of the entire camera-integrated video tape recorder 1.

  That is, the system control circuit 13 controls the memory control circuit 18 when the camera-integrated video tape recorder 1 is loaded with the magnetic tape 2 and the memory 16 and the camera-integrated video tape recorder 1 is set to the standby mode. Then, the management data in the memory 16 is rewritten with the volume data of the magnetic tape 2, thereby recording the correspondence relationship with the magnetic tape 2 in the memory 16.

  Further, in this state, the system control circuit 13 sets the memory control circuit 18 to the standby mode, and sequentially records the digital video signal DV1 and the digital audio signal DA in the first recording area AR0. When the cameraman presses the recording button 15 in this state, the system control circuit 13 switches the operation mode of the entire camera-integrated video tape recorder 1 to the recording mode, and sequentially inputs the digital video signal DV1 and the digital audio signal DA. Are recorded on the magnetic tape 2 and the recording of the digital video signal DV1 and the digital audio signal DA to the memory 16 is stopped.

  In response to this, the memory control circuit 18 adds the address value by 1 to the address data ADm + 1 (ie, the address data ADm for which recording of the digital video signal DV1 and the digital audio signal DA has been stopped (FIG. 3)). The address data of the memory 16 immediately before starting the subsequent recording, and the address data in which the oldest video signal DV1 and audio signal DA are recorded in the recording area AR0) are generated, and this address data ADm + 1 is associated Record in the system area. At the same time, the index signal ID0 output from the system control circuit 13 is recorded in the corresponding system area, and the next standby state is awaited.

  Correspondingly, when recording on the magnetic tape 2 is started, the system control circuit 13 outputs this index signal ID to the memory 16, and outputs this index signal ID to the recording amplifier circuit 14 and the rotary transformer 7, Thus, by effectively using the index signal, the correspondence between the digital video signal DV1 and digital audio signal DA recorded in the memory 16 and the digital video signal DV1 and digital audio signal DA subsequently recorded on the magnetic tape 2 is magnetically determined. Recorded on the tape 2 and the memory 16.

  Further, the system control circuit 13 stops recording on the magnetic tape 2 when the cameraman presses the recording button 15 again in this state and the operation mode of the camera-integrated video tape recorder 1 is set to the standby mode. Recording of the digital video signal DV1 and digital audio signal DA is started in the recording area AR1 of the memory 16. As a result, in the camera-integrated video tape recorder 1, the image pickup result can be held in the memory 16 for a specified time immediately before the recording on the magnetic tape 2 is started, and the deterioration of mobility is effectively avoided and valuable shooting is performed. You can record without missing the opportunity. Further, at this time, the correspondence relationship between the magnetic tape 2 and the memory 16 is clarified on the basis of the index signal ID, so that the corresponding digital video signal DV1 and digital audio signal on the basis of the index signal ID can be used in editing and the like. DA can be reproduced continuously, and processing such as editing can be executed efficiently.

  That is, FIG. 5 is a block diagram showing a video tape recorder of an editing system for editing the magnetic tape 2 recorded by the camera-integrated video tape recorder 1. In this editing system, the digital video signal DV1 and the digital audio signal DA recorded in the magnetic tape 2 and the memory 16 corresponding to the magnetic tape 2 are reproduced by the video tape recorder 20 and re-recorded in another video tape recorder, Other video tape recorders edit the digital video signal DV1 and the digital audio signal DA.

  That is, in this video tape recorder 20, the reproduction amplification circuit 21 is mounted on a rotating drum, amplifies the reproduction signal obtained from the magnetic head, and outputs it to the rotary transformer 22, and the rotary transformer 22 demodulates the reproduction signal. 24.

  The demodulating circuit 24 takes in the reproduced signal at a prescribed timing, binarizes it, decodes the serial data obtained as a result, and outputs it. The subsequent error correction circuit 28 performs error correction processing on the output data of the demodulation circuit 24, thereby reproducing and outputting the digital audio signal DA and the digital video signal DV1. The digital / analog conversion circuit (D / A) 27 performs digital / analog conversion processing on the sequentially input digital audio signal DA, thereby reproducing and outputting the original audio signal SA.

  On the other hand, the video signal decompression circuit 29 decompresses the sequentially input digital video signal DV1, thereby reproducing and outputting the digital video signal DV.

  The reproduction amplifier circuit 30 amplifies and outputs a reproduction signal of the magnetic tape 2 obtained from the fixed head. The demodulation circuit 31 takes in the reproduction signal output from the reproduction amplifier circuit 30 and binarizes it, thereby reproducing and outputting the index signal ID. The reproduction amplifier circuit 30 takes in the reproduction signal output from the rotary transformer 22 and binarizes it, thereby reproducing and outputting the index signal ID recorded obliquely on the magnetic tape 2.

  As a result, in the video tape recorder 20, when the magnetic tape 2 is cued by fast-forwarding, rewinding, etc., the index signal ID recorded in the longitudinal direction of the magnetic tape 2 is quickly cued and editing processing is performed in units of recording tracks. In some cases, the index signal ID recorded obliquely on the magnetic tape 2 can be reliably processed.

  In addition to the reproduction system for the magnetic tape 2, in the video tape recorder 20, the rate conversion circuit 32 converts the 16-bit parallel digital video signal and digital audio signal output from the memory 16 during reproduction into the original bit-parallel data. Convert to and output. The memory control circuit 33 outputs address data and the like to the memory 16 and controls the operation of the memory 16.

  The system control circuit 34 is formed by a microcomputer that controls the entire operation of the video tape recorder 20, and is based on the index signal ID read from the memory 16 and the index signal ID reproduced from the magnetic tape 2. 16 and the magnetic tape 2 sequentially output the digital video signal DV1 and the digital audio signal DA to the video signal decompression circuit 29 and the digital-analog conversion circuit 27, so that the correspondence is clearly indicated by the index signal ID and the memory 16 and the magnetic tape 2 The digital video signal DV1 and the digital audio signal DA divided and recorded are continuously reproduced.

  That is, the system control circuit 34 first reads out the address data AD at the head recording position of the first recording area AR0 and the corresponding index signal ID from the system area of the memory 16. Subsequently, the system control circuit 34 fast-forwards and rewinds the magnetic tape 2 while monitoring the index signal ID obtained from the reproduction amplifier circuit 30, and puts the magnetic tape 2 at the recording start position corresponding to the first recording area AR0. After taking out, the traveling of the magnetic tape 2 is stopped and kept in a reproduction standby state.

  Subsequently, the system control circuit 34 outputs the address data AD together with the read command to the memory control circuit 33. In response to this, the memory control circuit 33 sequentially issues address data from the recording start position specified by the address data AD, reads the digital video signal DV1 and the digital audio signal DA from the memory 16, and reads the read data. The signals DV1 and DA are output to the video signal decompression circuit 29 and the digital / analog conversion circuit 27. As a result, the video tape recorder 20 outputs the digital video signal DV1 and the digital audio signal DA recorded in the memory 16 to the video tape recorder for dubbing.

  In this state, the system control circuit 34 monitors the operation of the memory control circuit 33. When the memory control circuit 33 stops the read operation at the address immediately before the address data AD, the standby state of the magnetic tape 2 is canceled and the magnetic tape 2 is released. The whole operation is controlled so as to start the reproduction of No. 2. As a result, the video tape recorder 20 outputs the digital video signal DV1 and digital audio signal DA that have been recorded immediately before the recording button 15 is pressed to the video tape recorder for dubbing following the digital video signal DV1 and digital audio signal DA. To do.

  In this state, the system control circuit 34 loads the index signal ID and recording start address data AD of the recording area AR1 continuing from the system area of the memory 16, and when the recording start position of the subsequent material on the magnetic tape 2 is reached, the magnetic tape 2 is loaded. Switching to the reproduction standby state, the subsequent digital video signal DV1 and digital audio signal DA are read from the memory 16 with reference to the recording start address data AD. As a result, the video tape recorder 20 repeats this series of processing to separately record the digital video signal DV1 and the digital audio signal DA recorded on the magnetic tape 2 and the memory 16 on the magnetic tape, and then performs the same processing as in the prior art. The editing work can be executed according to the procedure.

  In the above configuration, in the camera-integrated video tape recorder 1 (FIG. 1), when the cameraman is set in the standby state, the digital video signal DV obtained by imaging the subject is approximately 1/10 in the video signal compression circuit 4. After being compressed to the data amount, it is input to the rate conversion circuit 17 together with the digital audio signal DA, where it is converted into 16-bit parallel data. The 16-bit parallel data is sequentially and cyclically recorded in a prescribed recording area formed in the data area of the memory 16, whereby the latest digital video signal DV1 and digital audio signal DA are recorded in this recording area. The memory space is always retained.

  When the cameraman presses the recording button 15 in this state, the writing of the digital video signal DV1 and the digital audio signal DA to the memory 16 is controlled to be stopped, whereby the digital video signal DV1 and the digital audio immediately before pressing the recording button 15 are controlled. The signal DA is held in the memory 16. Simultaneously, recording on the magnetic tape 2 is started, and the digital video signal DV1 and the digital audio signal DA are obliquely recorded on the magnetic tape 2 via the error correction code adding circuit 5, the modulation circuit 6, the rotary transformer 7, and the recording amplification circuit 8. The

  As a result, the digital video signal DV1 and the digital audio signal DA after the recording button 15 is pressed are recorded on the magnetic tape 2, and a series of subjects are recorded from a predetermined period immediately before the recording button 15 is pressed with the memory 16 and the magnetic tape 2. Images can be taken and recorded without missing precious photo opportunities.

  At this time, the system control circuit 13 outputs an index signal ID, and the system control circuit 13 generates address data AD at the head recording position from the recording end position of the memory 16. The address data AD and index signal ID of the head recording position are recorded in the system area of the memory 16, and the index signal ID is recorded in the recording start position of the magnetic tape 2, the recording track extending in the longitudinal direction, and the oblique recording track. To be recorded. As a result, the relationship between the recording contents of the magnetic tape 2 and the memory 16 is recorded in the memory 16 and the magnetic tape 2, and the reproduction start position of the memory 16 is recorded in the system area of the memory 16.

  As a result, at the time of reproduction, the digital video signal DV1 and the digital audio signal DA are reproduced from the head recording position recorded in the memory 16, and then the corresponding digital video signal DV1 and digital audio signal DA are magnetized on the basis of the index signal ID. A series of contents reproduced from the tape 2 and divided and recorded in the magnetic tape 2 and the memory 16 can be reproduced in the order of recording.

  According to the above configuration, in the standby state, the digital video signal DV1 and the digital audio signal DA are sequentially and cyclically recorded in the memory 16, and when the recording button 15 is pressed, the recording of the memory 16 is stopped and the magnetic By recording the digital video signal DV1 and the digital audio signal DA on the tape 2, the digital video signal DV1 and the digital audio signal DA immediately before pressing the recording button 15 can be recorded. As a result, by simply mounting a memory card, it is possible to image a subject without missing a valuable shooting opportunity, and accordingly, it is possible to effectively avoid deterioration in mobility of the camera-integrated video tape recorder.

  At this time, the index signal is recorded, and the contents of the memory 16 and the magnetic tape 2 are recorded in association with each other. Therefore, even when a large number of materials are recorded on the magnetic tape 2 by repeatedly pressing the recording button 15, the magnetic tape 2, the corresponding digital video signal DV1 and digital audio signal DA can be reliably reproduced from the memory 16.

  In the above-described embodiment, the case where the editing system re-records and edits the digital video signal DV1 and the digital audio signal DA with another video tape recorder has been described. You may make it re-record on an apparatus, an optical disk apparatus, etc. In these cases, the editing process may be directly performed based on the contents of the system area and the index signal recorded on the magnetic tape.

  In the above-described embodiment, the case where the same index signal is recorded in the magnetic tape 2 and the memory 16 has been described. However, the present invention is not limited to this, and the recording contents of the magnetic tape 2 and the memory 16 are important. If the correspondence can be grasped, various identification signals can be applied. For example, different index signals may be recorded in the magnetic tape 2 and the memory 16. Further, instead of the index signal, the contents of the system area corresponding to the magnetic tape side may be recorded and used as the identification signal.

  Further, in the above-described embodiment, the case where the imaging result is recorded on the magnetic tape and the memory card has been described. However, the present invention is not limited to this. For example, prior to unloading of the magnetic tape, the contents of the memory 16 are magnetically It is also possible to record the imaging results collectively on the magnetic tape 2 by re-recording them together in the specified area of the tape 2.

  In the above-described embodiment, the case where the magnetic tape is used as the recording medium has been described. However, the present invention is not limited to this, and various recordings such as a case where a magnetic disk is used as the recording medium and an optical disk is used. The present invention can be widely applied when recording a video signal using a medium. When these recording media such as magnetic disks are used, the prescribed areas of these recording media may be used instead of the memory 16.
