If the switch S1 is on, Then, it is determined whether or not still image recording has been performed (step ST42). This is an operation in which if the moving image recording preparation sequence described with reference to FIG. 6 is completed and moving image recording is ready, it is determined that the image is not a still image recording, and otherwise, it is determined that the image is a still image recording. is there.

If the switch S1 is not turned on, the operation of step S41 is repeated until the switch S1 is turned on.

If it is determined in step ST42 that the recording is not a still image recording, that is, it is a moving image recording, it is determined in step ST43 whether or not the switch S2 is turned on, that is, whether or not the release button 7 is fully pressed. If the switch S2 is turned on, the CPU 100 (FIG. 4) executes the signal processing unit 102 based on the installed moving image processing software.
To perform predetermined image processing on the moving image data (step ST44).

Then, the processed moving image data is output to the recording section 111 of the camera body 1 and is output to the moving image card 20 (FIG. 4) via the interface 112 (step ST45).

The processed moving image data is recorded by the recording unit 111 (step ST46).
CPU 21 receives the processed moving image data via the interface 24 and records it on the recording medium 22 (step ST61).

If the writing speed of the moving picture card 20 is high and the writing capacity per unit time is larger than the input data, moving pictures can be recorded continuously. Also, needless to say, even if the writing capacity per unit time is smaller than the input data, the moving image can be continuously recorded until the recording medium is full.

If the switch S2 has not been turned on in step ST43, it is checked again whether the switch S1 has been turned on (step S49). If the switch S1 has been turned on, the process proceeds to step ST43. Is repeated.

If the switch S1 is not turned on in step ST49, the operation after step ST41 is repeated.

The image processing for the moving image data and the output of the processed moving image data continue until the release button 7 is completely depressed, that is, until the switch S2 is turned off (step ST47). After confirming that the switch has been turned off, in step ST48, it is checked whether or not the switch S1 has been turned off, that is, whether or not the half-pressed state of the release button 7 has been released. If the switch S1 is off, a series of photographing operations is completed, and the process returns to step ST41 to monitor the switch S1 and prepare for the next photographing operation.

If the switch S1 has not been turned off in step ST48, the operation after step ST43 is repeated.

If it is determined in step ST42 that the recording is a still image recording, the process proceeds to steps ST21 to ST21.
The still image recording sequence shown in ST27 is executed,
Since this is the same as that shown in FIG. 7, the description is omitted.

As described above, moving image processing is not performed on the moving image card, but software for moving image processing is installed from the moving image card into the camera body, and moving image processing is performed on the camera body. When the processing method is developed, the user can obtain a digital camera system compatible with the latest image processing method simply by replacing the moving image card, and does not feel inconvenience due to the change of the image processing method.
