Abstract

PURPOSE: To relatively easily perform high-speed consecutive photographing and record picture data obtained by photographing. CONSTITUTION: When a shutter release button 32 is pushed while a consecutive photographing mode is set by the mode setting button 31 of an operation panel 30, digital picture data for plural frames obtained by the consecutive photographing of an object are supplied to a memory card 42 and recorded. When a disk transfer button 33 is pushed, the picture data tentatively recorded in the memory card 42 are read and recorded in a magneto-optical disk. When a memory transfer button 34 is pushed, the picture data recorded in the magneto-optical disk are read and recorded in the memory card 42. The picture data recorded in the memory card 42 are read and supplied to a reproducing circuit 21, a reproducing processing is performed by the reproducing circuit 21 and output is performed. Since the access time of the memory card 42 is shorter than the one of the magneto-optical disk, the high-speed consecutive photographing is made possible.

It is given to the memory card 42 via the CSI controller 19 and recorded (step 75). When the memory card reproduction button 39 is pressed, the image data transferred from the magneto-optical disk 41 and recorded in the memory card 42 is read from the memory card 42 between times t ₅₄ and t ₅₅ (step 76), It is given to the reproduction circuit 21. Time t ₅₅ to t ₅₆
At the reproduction circuit 21, reproduction processing of image data is performed (step 77).

Unlike the data reading from the magneto-optical disk, the data reading from the memory card 42 does not require the transfer of the magneto-optical head. Therefore, arbitrary data can be read quickly.

Further, although the magneto-optical disk is used as the recording medium in the above embodiment, a memory card may be used instead of the magneto-optical disk. When a memory card is used instead of the magneto-optical disk,
If the read speed of this memory card is faster than the read speed of the expansion memory 42, the image data is stored in the memory card when the image data recorded in the memory card is reproduced.
It is given to the reproduction circuit 21 without being transferred to the card 42.

In the above-described embodiment, still image data obtained by continuous shooting is temporarily stored in the memory card 42, and then the all record button 38a and the select record button 38b.
The still image data is sent to the memory card 42 when the
Although the image data is transferred to and recorded from the magneto-optical disk, the still image data obtained by shooting in response to the end of continuous shooting can be transferred and recorded to the magneto-optical disk even if these buttons 38a and 38b are not pressed. You may

Further, in FIG. 1, buses are displayed along the flow of data, but in practice, buses will be commonly used.

Furthermore, transfer from the memory card 42 to the magneto-optical disk or from the magneto-optical disk to the memory card
The transfer to 42 may transfer all of the data recorded in each recording medium as described above, may transfer a necessary part of the data, or may transfer the data to a group. Data may be transferred separately for each group.
