An L changeover switch 47 is provided. The EVF 14 of the camera is attached to the front side surface of the camera body.
Is provided for the eyepiece 49.

Next, the high speed search during the interval reproduction by the camera of this embodiment will be described.

First, in order to perform interval reproduction, the changeover switch 46 is switched to the reproduction mode, and then D
Interval playback is designated by the RIVE switch 41. In addition, the zoom switches 31 and 32 are operated to set the interval time in seconds. The set time is stored in the setting memory 21, and the set value is held even in the power off state. Then, it will be referred to when the interval reproduction is executed again.

Here, in the above interval reproduction, the interval time itself, which is usually several seconds, is variable. Furthermore, in order to temporarily execute high-speed search frame advance, without changing the set interval time,
It is configured so that the interval time can be shortened with one touch. This will make the camera even easier to use. The above one-touch operation can be performed by, for example, UP / DOW.
By operating the N switches 33 and 34,
By pressing the switches 33 and 34, the frame advance speed can be temporarily increased. Here, a part of the system controller 19 and the UP / DOWN switches 33, 34 and the like constitute a high speed reproducing means.

Next, interval photographing by the camera of this embodiment will be described.

Interval shooting by a conventional electronic still camera system is a known shooting method, but in this interval shooting, the power supply is kept on during the shooting period. In a system where the power source is a battery,
Due to the large amount of power consumption, it was difficult to perform long interval shooting.

Since it is not always necessary to keep the ON state during the interval photographing, in the camera of the present embodiment, the standby state close to the power-off is set during the photographing waiting time to suppress the power consumption. I chose
Then, the power is turned on several tens of seconds before every shooting to prepare for shooting. During this shooting preparation time, processing such as strobe charging and automatic WB is performed. In addition, zooming is prohibited during interval shooting to prevent shifting of the focusing due to changes in the shooting angle of view.

In many cases, the interval time was conventionally fixed, but in the present embodiment, a certain interval time is held as a preset value.
The value can be finely changed and rewritten by the UP / DOWN switches 33, 34 and the like. The set value is stored in the setting memory 21 via the system controller 19. When performing the same interval shooting, the interval time can be easily set by reading the value stored in the setting memory 21 without any troublesome operation. The set value data is retained even in the power off state.

FIG. 7 is a flow chart of the interval photographing subroutine.

In the main photographing process, the photographing start instruction is confirmed in step S31, and the first frame is photographed in step S32. Immediately thereafter, the camera shifts to the standby state, and at the same time, the zoom drive is prohibited (step S33). In step S34, a predetermined time, which is shorter than the interval setting time by several tens of seconds, is waited for, and after that time, the power is turned on in step S35.
Then, in step S36, strobe charge and auto W are performed.
After performing the B process, the process proceeds to step S37, waits until the interval time elapses, and starts shooting at step S38. In step S39, the shooting of a predetermined number of frames is completed or the elapsed shooting time is checked, and the process returns to step S33 until the shooting is completed. Now, in the conventional initialization process of FIG. 10 described above, if the memory card is pulled out or the power of the device is turned off during the erase operation, the boot sector is written in a normal state, and the directory entry is also written. It is possible that the memory card is taken out even though it has been erased but the FAT has not been erased.

Normally, in the memory card, the free capacity is discriminated by the size of the range in which each FAT data is "0". Therefore, if the FAT has not been erased as described above, it is determined that the capacity is small.

The file currently being searched for is FA
By tracking the T data chain, it is possible to distinguish between a normal FAT and an abnormal FAT, so it is possible to correct it. For example, a check process up to that point with an image recording / reproducing device such as a camera. Is not appropriate to execute every time the memory card is inserted. Such a check process is
Even in a personal computer or the like, the process is executed only by a single check command and is not performed during normal operation.

Therefore, in the present embodiment, a quick process of initializing the information recording medium is possible, and even if the normal initializing process of the information recording medium is not executed, the above recording is performed thereafter. This makes it possible to perform normal initialization without causing any inconvenience in handling the medium.

Initialization processing of the memory card 10 in the camera of this embodiment will be described with reference to the flowchart of the subroutine of FIG.

ERASE switch 36 and UP switch 3
3 is pressed to set the camera in the initialization mode, and when the trigger switch 45 is pressed, the memory card 10 is pressed.
The above initialization process is started.

First, the boot sector of the first management information area is read (step S1), and the management information discriminating means
It is checked whether the boot sector information is suitable for the device (step S2). If the boot sector information is incorrect, the management area below the boot sector, that is, the first management area of the boot sector and the FA
T and the second management area of the directory entry and the formatting process for initializing all the data in the data area which is the main information storage area (step S).
7).

If the boot sector information is suitable for the device, the management information initializing means temporarily changes the boot sector to make the boot sector information improper (step S3), and The entry is erased and the FAT is initialized (step S).
4, S5). After that, the management information restoring means restores the boot sector to the original boot sector to make it a suitable boot sector (step S6), and finishes the initialization.

As described above, in the case of the initialization processing of the conventional memory card shown in FIG. 10, if the card is pulled out during the erasing, the boot sector is normal, but the directory entry and the FAT are not connected properly. It becomes a consistent state. When such a card was inserted into the camera, it was used with the recordable data area being extremely narrowed, or it became impossible to record.

However, in the camera of this embodiment, by performing the above-mentioned initialization processing, since the memory card 10 pulled out in the middle of the processing is not the data whose boot sector is suitable for the corresponding apparatus, Even if it is inserted in the camera, it is in a state where it cannot be used, and problems such as recording will not occur. Further, when the card is initialized again, the boot sector is not a proper one, so the initialization is always performed in the format of step S7 in FIG.

In the camera of this embodiment, it is possible to forcibly execute the format of step S7, in addition to the initialization by the automatic discrimination. In this process, the forced initialization mode is set by pressing the ERASE switch 36 and the DOWN switch 34, and when the trigger switch 45 is pressed there, the management area and the data area of the memory card 10 are forcibly changed. Both format processes are started.

In the initialization processing of the memory card 10, if it is found necessary to save the data recorded during the initialization processing, the above-mentioned conventional method is used even if the initialization operation is interrupted. The data could not be replayed. Even in such a case, it is possible to propose a modification in which the directory entry and the FAT corresponding to the corresponding data can be reproduced if they have not been deleted yet.

In the initialization processing in this modified example, as shown in FIG.
In the boot sector shown in (1), a check flag is written in an area that is not directly related to data processing, for example, a manufacturer name and a version number area. In that case, other boot sectors are not changed. Then, if the initialization is interrupted for the above reason, pull out the memory card and insert it into the personal computer.
Data can be reproduced. That is, the flag can be checked on the personal computer to set the reproduction mode of the data being erased, and the range of the data not yet erased can be restored.

As described above, in this embodiment, when the information recording medium is initialized to the unrecorded state of the main information or the state equivalent to the unrecorded state, the management information of the first management information area is determined, When the management information in the first management information area is suitable for the corresponding information handling device, the management information that does not match the first management information area is once recorded, and the second management information area is initialized. After that, the original management information suitable for the first management information area is written, so that if the normal initialization processing of the information recording medium is not executed, the information recording medium becomes unusable, which is inconvenient. It is possible to prevent the occurrence of the error and at the same time, perform the normal initialization process of the recording medium.

Next, the data erasing process in the camera of this embodiment will be described.

As the data files recorded in the data area of the conventional image recording / reproducing apparatus such as a camera, three types of files shown in the formats of FIGS. 11, 12, and 13 are created. The data file in the format shown in FIG. 11 is an image data file of one frame,
It is composed of header information such as recording date and time, fields / frames and the like, and image data which is compressed image data. 12
Indicates the format of an audio data file of one frame which is a file generated in a camera capable of audio recording, and is composed of header information and audio data which is compressed audio data. Further, FIG. 13 shows a format of a relation data file showing a relation of a combination of an image file and an audio file corresponding to one directory entry, in which header information in which standard information is recorded and related information between files are recorded. Relation information.

In the data erasing process of this embodiment, one frame of the image file and one frame of the audio file can be erased. Further, the image file and the image file can be erased based on the relation file data. It is possible to delete the audio files corresponding to the image files all at once.

Of course, deleting all frames of the image file,
It is also possible to erase all frames of an audio file.

In the camera of this embodiment, the key operation for erasing one frame at the time of reproduction is to switch the selector switch 46 to the "PLAY" side and
While pressing the ERASE switch 36 that also serves as the W switch, the release switch 45 is operated to execute the erasing.

On the other hand, there is a so-called REC review reproduction function of reproducing the recorded image data immediately before recording, and this reproduction function is the ERAS which is also used as the view (VIEW) switch while the changeover switch 46 remains at the CAMERA side.
While the E switch 36 is being pressed, the REC review reproduction function works. Therefore, when erasing the image data of the rec review reproduction, the release switch 4 is directly used.
5 should be pressed.

As described above, in the camera of this embodiment, since the VIEW switch and the ERASE switch are also used as described above, the one-frame erasing operation at the time of the normal reproduction and the REC review reproduction data are performed. The erasing operation can be executed by the same operation, and the user does not feel uncomfortable.

In the camera of this embodiment, as described above, not only the image data file but also audio data, relation data, personal computer data, etc. are recorded as data to be recorded in the data area. During normal reproduction, data of files other than those image data files and the unrecorded data portion are reproduced as a black mute screen. Therefore, in the present embodiment, in order to inform that the data other than the image data file is being reproduced, the on-screen display and the frame No. corresponding to the LCD display unit 17 are displayed. Blinks.

Also, voice data, relation data,
It is also possible to change the blinking speed depending on the difference in the data of the unrecorded portion and the like. Alternatively, the color of the mute screen can be made different depending on the difference in the above data. For example, the user can be identified at a glance by setting the unrecorded part to black mute, the audio file to blue mute, and the personal computer file to red mute.

Further, at the time of reproduction, it is also possible to skip the non-image file such as unrecorded file or audio file and reproduce. According to such reproduction, the user does not need to see the meaningless mute screen of unrecorded frames, etc., and can search efficiently.

That is, as the reproduction processing at a predetermined interval, there are continuous reproduction for searching the image data at a high speed and interval reproduction for transmitting a reproduced image at every fixed time. This high-speed search processing is a high-speed search. It is a function used at the time of demonstration, and it is not necessary to reproduce anything other than image data. Therefore, when these functions are working, the audio file, the unrecorded file, etc. are skipped and only the image file is reproduced, which can be very convenient.

Next, various recording processes in the camera of this embodiment will be described.

As described above, the header information is added to the image data file of one frame in order to record the data format of the image data. In the camera of this embodiment, shooting information of the camera, for example, shutter speed, exposure information, WB (white balance) information, color adjustment information, focus step number information, strobe exposure information, etc. are recorded in this header. Therefore, even when shooting is performed in full auto, it is possible to know the various shooting information by referring to the header information after shooting.

Further, the photographing conditions can be set on the basis of the photographing information recorded in the header, and the photographing can be performed. The photographing process will be described with reference to the flowcharts of FIGS.

In the flowchart of FIG. 5, the changeover switch 46 is set to "PLAY" in step S11.
Switch to the side and set to playback mode. And UP /
Operate the DOWN switches 33 and 34 to display the playback frame of the image for which the shooting conditions are to be referred to, and to display the PICTU.
With the RE switch 40, the frame No. Is specified. In step S12, the subroutine "set of shooting mode"
The process is called and executed.

In the subroutine "set of shooting mode", shooting information such as shutter speed and exposure information is read from the header information of the image file of the corresponding frame as shown in FIG. 6 (step S21). Based on this, the shooting conditions are set (step S22).

Then, in step S13 of FIG.
The selector switch 46 is switched to the "CAMERA" side, and the camera is set to the shooting mode. In step S14, shooting is performed under the shooting conditions that have already been set.

In this way, the shooting conditions on the past shooting screen can be reproduced without complicated setting operations, and if there is a memory card already taken by another shooter, the shooting conditions on that shooting screen will remain unchanged. It is also possible to apply.

Next, WB (white balance) adjustment in the camera of this embodiment will be described.

Generally, it is necessary to adjust WB in a video camera, but in a conventional camera, adjustment of auto WB, one-touch WB, and preset WB was possible.

The automatic WB adjustment is an adjustment for automatically setting the position of the WB correction center on the color vector plane shown in FIG. 14 so that an appropriate WB can be obtained based on the input image signal. The drawback of this adjustment is that when the color in the entire screen is offset to a certain color, the color is corrected so that it becomes white, so that it is not always possible to record with a good color tone.

In the one-touch WB adjustment, the image signal of a white object is captured and the signal is adjusted to be recognized as white. In this adjustment, it is necessary to carry a pure white object, which is inconvenient.

In the preset WB adjustment, a plurality of typical color temperature values are stored in the system as the WB correction center value data, and the color temperature values are adjusted according to the condition of the subject such as fine and cloudy. Select. For example, on the I-axis indicating the blackbody locus on the color vector plane of FIG. 14, WB correction is performed on either point P0 when it is sunny, point P1 when it is cloudy, or point P2 when it is sunset. Set to the center and adjust WB. However, with this adjustment, the delicate WB adjustment desired by the user cannot always be performed.

In order to solve the above problems, conventionally, R (red) -Y (luminance) of the color vector plane of FIG. 14 is conventionally used.
A method of manually performing fine adjustment of WB by setting variables of two axes of the axis and B (blue) -Y axis to determine the WB correction center has been adopted. However, in such a method, it is difficult to perform adjustment because it is necessary to set two values.

Therefore, in the camera of the present embodiment, as the WB fine adjustment processing, the WB correction points can be set on one axis to enable easier WB manual fine adjustment processing. .

That is, the method of this manual WB fine adjustment is such that each component of (RY) and (BY) is moved along the I axis which is one inclined axis of the color vector plane of FIG. The value is set as the WB correction center. It should be noted that the I axis is a line showing a black body locus along the change in color temperature of the black body, and if the WB correction center is moved along the I axis, proper WB adjustment can be made. it can.

In the present embodiment, when performing WB fine adjustment, the inclination data of the I-axis is stored in the memory, and first, as a correction adjustment point, a point P when the weather is fine in FIG.
Either 0 or a point P1 when cloudy or a point P2 when sunset is selected. Further, at each point, the UP / DOWN switches 33, 34 are operated to move the WB correction center along the inclination of the I-axis,
Fine-tune B.

Thus, the WB in the camera of this embodiment
Fine adjustment can be performed by a simple operation, and by performing this adjustment, it is possible to perform shooting with a delicate color tone desired by the user.

As is apparent from the above description, according to the present invention, during the period in which the interval reproduction is performed at the preset predetermined time interval, the interval time is temporarily changed without changing the predetermined time interval. Since the high-speed search means for shortening the time interval to a high-speed search is provided so as to enable the high-speed search, the high-speed search can be performed even during the interval reproduction.
