[0002]

2. Description of the Related Art Conventionally, an electronic still camera or the like is known as an image processing apparatus for recording and reproducing a still image signal obtained by photoelectrically converting imaging light on a recording medium such as a magneto-optical disk or a magnetic tape. Has been.

In a conventional electronic still camera, image data (hereinafter referred to as first image data) in a format in which an image signal input from an image pickup section is subjected to predetermined processing and can be recorded in a recording medium is recorded in the recording medium. Record. The resolution of the first image data varies depending on the model of the electronic still camera, and many models use the standard format (640 × 480).
Image data having a resolution higher than that of dots) is recorded as the first image data. Therefore, in order to maintain compatibility between models, it is necessary to create standard format image data from the above-mentioned first image data and record it in a recording medium together with the first image data.

[0007]

Generally, the above-mentioned conventional electronic still camera has a single shooting mode in which a single image is recorded as the shooting mode, and the image is continuously shot at predetermined time intervals. It has a continuous shooting mode for recording. here,
An example of the recording processing time of the image data when shooting is performed in the continuous shooting mode in the conventional electronic still camera is shown in the upper part of FIG. That is, in this example, every time one first image data is recorded, the second image data corresponding to the first image data is recorded.
The image, that is, the image data of the standard format and the index image are recorded on the recording medium. That is, the second
After the image recording is completed, the next first image data can be recorded.

For example, the transfer speed (writing speed) of image data to a recording medium such as a magneto-optical disk or a magnetic tape is
It is slower than the processing speed of the imaging unit and the circuit that processes the output from the imaging unit. Therefore, the conventional electronic still camera has a problem that the continuous shooting interval in the continuous shooting mode cannot be shortened. Further, the continuous shooting interval increases as the second image data increases. In addition, the above problem is

When recording the image data, the buffer memory 5 temporarily stores the image signals (first and second image data) compression-encoded by the compression / expansion processing circuit 11 in order to measure the recording timing. . During reproduction, the signal processed by the digital signal processing circuit 4 is temporarily stored when it is transferred to the compression / expansion processing circuit 11 in order to measure the reproduction output timing. The system control microcomputer 6 (recording control means) is realized by a microcomputer or the like and controls the operation of the entire control system of the electronic still camera.

D converter circuit (not shown) and D for D / A conversion
/ A converter circuit (not shown).

The controller 17 includes various switches such as, for example, a power ON / OFF switch, a recording standby switch, a recording switch, and a reproducing switch, which are used by the operator to perform various operations (all not shown).

The display unit 15 is realized by, for example, a liquid crystal display. The image pickup unit 16 includes, for example, a lens and a color CCD (Charge Coupled Device) not shown.
And has a function of photoelectrically converting an image. The host IF unit 18 is an interface for connecting an external host computer, printer or the like to the present electronic still camera.

When recording, the operator depresses the recording standby switch and captures an image from the image capturing section 16. The captured image captured is displayed on the display unit 15 as a still image. While the recording standby switch is being pressed, new imaging is captured from the imaging unit 16 at a predetermined time interval and displayed on the display unit 15. The operator
By looking at the display unit 15 and pressing the recording switch when the image to be recorded is displayed, the image is recorded on the magneto-optical disk 1.

When reproducing, when the operator depresses the reproduction switch, a plurality of index images of the images recorded on the magneto-optical disk 1 are simultaneously displayed on the display section 15. The operator selects one of the index images to display the image on the display screen of the display unit 15 or to display the image on the external host computer or printer connected via the host IF unit 18. The desired processing can be performed by sending the image.

Next, the operation of each block in FIG. 1 when recording or reproducing is performed in this electronic still camera will be described. First, the processing during reproduction will be described. When the operator presses a reproduction switch (not shown) of the controller 17, the mechanical unit 8 drives the spindle motor 10 to rotate the magneto-optical disk 1. At the same time, the feed motor 9 driven by the mechanical unit 8 feeds the optical pickup 2 in the radial direction of the magneto-optical disc 1, and the optical pickup 2 reads the signal recorded on the magneto-optical disc 1. The signal read by the optical pickup 2 is amplified in the analog signal processing circuit 3 and sent to the digital signal processing circuit 4.

The analog signal processing circuit 3 also generates a servo control signal such as a focus error signal or a tracking error signal from the signal read by the optical pickup 2 and supplies it to the servo section 7. The servo unit 7 controls the mechanical unit 8 so as to apply focus, tracking, and spin servo by a servo control signal from the analog signal processing circuit 3 and a control signal from the system control microcomputer 6. Then, the mechanical unit 8 drives the optical pickup 2, the feed motor 9, and the spindle motor 10 by the control signal from the servo unit 7.

The digital signal processing circuit 4 performs signal processing such as demodulation and error correction on the signal amplified by the analog signal processing circuit 3 and sends it to the compression / decompression processing circuit 11.
Here, the signal sent from the digital signal processing circuit 4 to the compression / expansion processing circuit 11 remains in a compressed state. Therefore, the compression / expansion processing circuit 11 expands the signal transferred from the digital signal processing circuit 4 to convert it into the converter 1
Transfer to 2. The converter 12 includes the compression / expansion processing circuit 1
The signal transferred from 1 is converted into an analog signal and sent to the display unit 15. The display unit 15 displays the signal sent from the converter 12 as a still image.

When the reproduced signal is transferred to an external host computer or the like, the digital signal processing circuit 4 outputs the signal in the compressed state as it is to the host IF section 18.
And is transferred to the host computer or the like via the host IF unit 18.

Next, the processing of each block during recording will be described. The image signal input from the image pickup unit 16 is digitized by the A / D converter circuit of the converter 12, subjected to predetermined correction processing and compression encoding processing by the compression / expansion processing circuit 11, and then the digital signal processing circuit 4 Sent to. The digital signal processing circuit 4 performs signal processing such as modulation of the signal sent from the compression / expansion processing circuit 11 and addition of error correction bits. The data obtained here is the first image data. That is, the converter 12, the compression / expansion processing circuit 11, and the digital signal processing circuit 4 constitute the first image data creating means of the present invention. The obtained first image data is stored in the buffer memory 5.

Further, the digital signal processing circuit 4 performs arbitrary reduction processing or the like on the first image data as needed to generate second image data (standard format image data and index image). That is, the digital signal processing circuit 4 functions as the second image data creating means. The second image data is also stored in the buffer memory 5 in the same manner.

The first image data and the second image data stored in the buffer memory 5 are taken out in accordance with the procedure described later, the system control microcomputer 6 drives the head drive section 13, and the optical pickup 2 emits laser light. At the same time, the recording head 14 applies a magnetic field to record on the magneto-optical disk 1.

2 and 3 are flowcharts showing the procedure of the operation executed in each block of FIG. Note that the flowcharts of FIGS. 2 and 3 are continuous with each other by the terminals A and B shown in the drawings. When the operator presses the power ON switch of the controller 17 to turn on the electronic still camera and mount the magneto-optical disk 1, the operation is started. The operator inputs whether to perform recording or reproduction as an operation instruction by pressing a switch provided in the controller 17. Alternatively, the operator may press the power OFF switch provided on the controller 17.

First, the system control microcomputer 6
Inputs an operation instruction from the controller 17 from the controller 17 (step 1, hereinafter referred to as S1). Next, in S2, it is determined whether the operation instruction content input in S1 is recording or reproduction, and if recording, the process proceeds to S3. The processing when the operation instruction content is reproduction will be described later.

In S3, the system control microcomputer 6 waits until the recording standby switch of the controller 17 is pressed. When the recording standby switch is pressed, the process proceeds to S4. In S4, under the control of the system control microcomputer 6, images are continuously captured from the image pickup unit 16, and the captured images are processed by the converter 12, the compression / expansion processing circuit 11, and the digital signal processing circuit 4 as described above. After that, it is recorded in the buffer memory 5 as the first image data.

Further, in S5, the controller 17
It is determined whether or not the recording switch of is pressed. When the recording switch is pressed (YES in S5), the image to be recorded is confirmed, and the first image data corresponding to the confirmed image is taken out from the buffer memory 5 and recorded on the magneto-optical disc 1 (S6). On the other hand, if it is determined in S5 that the recording switch has not been pressed, S4
Returning to, the next image is captured from the image pickup unit 16 and the process is continued.

When recording the first image data on the magneto-optical disk 1 in S6, information as to whether or not the recording of the second image data corresponding to the first image data is completed (recording condition). Is also recorded on the magneto-optical disk 1. The created situation is recorded in a predetermined recording area of the magneto-optical disc 1. When the recording is completed, the process returns to S3.

When the operator sets the continuous shooting mode by the controller 17, the recording process of the first image data in the buffer memory 5 in S4 is completed while the operator continues to press the recording switch. The recording switch is turned on every time
A signal is output from the controller 17 to the system control microcomputer 6. As a result, every time the first image data is recorded in the buffer memory 5, the recording of the first image data on the magneto-optical disk 1 is executed, and continuous images can be recorded.

By repeating the above steps S3 to S6, the first image data of the image desired by the operator is recorded on the magneto-optical disk 1. Further, in S6, only the first image data is recorded on the magneto-optical disk 1, and here, the second image data is recorded.
Since the image data is not created and recorded, the time required for recording can be shortened as compared with the method of recording both the first image data and the second image data as in the conventional electronic still camera.

Next, the operation procedure when the recording of the desired image on the magneto-optical disk 1 is once finished and the controller 17 depresses the power OFF switch or the reproduction switch as described above, the flowchart of FIG. It will be described based on.

First, the controller 17 turns off the power.
A case in which a power OFF command is input from the controller 17 to the system control microcomputer 6 in S1 of FIG. 2 by pressing the switch will be described. First, the recording status of standard format image data and index image data is read from a predetermined recording area of the magneto-optical disc 1 (S7). And
Based on the above recording condition, the system control microcomputer 6 finishes the creation of the second image data and the recording on the magneto-optical disc 1 for all the first image data recorded on the magneto-optical disc 1. It is determined whether or not (S8). If there is uncreated second image data (NO in S8), the process proceeds to S9.

In S9, the first image data in which the second image data is not created is read from the magneto-optical disk 1 based on the recording condition read from the magneto-optical disk 1. next,
The digital signal processing circuit 4 creates second image data from the read first image data (S10). The created second image data is temporarily stored in the buffer memory 5.

Next, the system control microcomputer 6
Takes out the created second image data from the buffer memory 5, records it in the respective predetermined recording areas of the magneto-optical disc 1, and records the second image data recorded on the magneto-optical disc 1. (S11),
Return to S8.

In this way, steps S8 to S11 are performed until the creation and recording of the second image data corresponding to all the first image data recorded on the magneto-optical disc 1 are completed.
Processing is repeated to record all the second image data on the magneto-optical disk 1, and then the power is turned off (S1
3) End the operation.

Further, even if the operator has instructed reproduction in S1, the power source O described above is executed prior to execution of the reproduction processing.
Similar to the case of FF, the processing of S7 to S11 is executed. Then, the second image data corresponding to the first image data recorded on the magneto-optical disc 1 is created and recorded, and if it is determined that all the second image data has been created (YES in S8), the process proceeds to S12. move on.

Since reproduction is instructed by the operator here, the process proceeds from S12 to S14. In S14, the index image data as the second image data recorded on the magneto-optical disk 1 is taken out and displayed on the display unit 15. A list of these index image data is displayed, and the operator is prompted to select an image to be reproduced.

When the image to be reproduced is decided, the process proceeds to S15,
The first image data on the magneto-optical disk 1 is read out, processed by the digital signal processing circuit 4, the compression / expansion processing circuit 11, the converter 12, etc., and then displayed on the display unit 15.

As described above, in the electronic still camera according to the present embodiment, when the image photographed by the operator is recorded on the magneto-optical disk 1, first, only the first image data is continuously recorded on the magneto-optical disk 1. Then, before the power is turned off or before the reproduction, the second image data is created from the first image data already recorded on the magneto-optical disk 1, and is recorded on the magneto-optical disk 1.

If is restarted, it is possible to create an uncreated standard image and index image data based on the recording status of the second image data recorded on the magneto-optical disc 1 and record it on the magneto-optical disc 1.

Further, since the above-mentioned recording situation is recorded in a predetermined recording area of the magneto-optical disk 1, when the power supply is restarted, the recording area is checked to easily and quickly detect the second image data. It is possible to confirm how far the recording operation has been completed. That is, it is possible to avoid a situation in which the second image data is recreated from the beginning when the power supply is restarted, and it is possible to reduce the trouble caused by the power shutdown.

Further, the electronic still camera according to the present embodiment, based on the recording status of the second image data recorded on the magneto-optical disc 1 prior to reproduction, determines whether or not there is any uncreated second image data. Is confirmed, and after the creation of all the second image data and the recording on the magneto-optical disk 1 are completed, the actual reproducing process is performed. This allows
It is possible to realize an electronic still camera capable of displaying index image data during reproduction and allowing the operator to select a reproduction image while shortening the continuous shooting interval at the time of shooting.
