[0057] The second example of the timing for forming and storing the still image group will now be described. FIG. 4 shows the timing for forming and storing the still image group in the second example. In the second embodiment, the still image group is formed and stored at the timing designated by the user. For example, if there is a favorite scene upon recording of the motion image 1, for example, the trigger operation such as depression of the switch or the like is executed. Operation information corresponding to the trigger operation is supplied to the system control unit 14.

[0058] The system control unit 14 to which the operation information has been supplied extracts a frame 55a of the motion image 1 and supplies it to the still image recording and reproduction processing unit 15. In the still image recording and reproduction processing unit 15, an index image corresponding to the frame 55a is formed and written into the storing medium 16.

[0059] Subsequently, the system control u

[0066]FIG. 5 shows the third example regarding the timing for forming and storing still image groups. In the third example, in a manner similar to the first embodiment, five frames near the head of each motion image are extracted, index images are formed, and still image groups 74 to 76 are formed. With respect to all of the recorded motion images, frames 81a to 81j are extracted at predetermined time intervals, index images are formed, and another still image group 84 is formed.

[0067] As mentioned above, the frames corresponding to the index images constructing the still image groups 74 to 76 and another still image group 84 are sequentially extracted in time order upon recording.

[0068] Related information showing a relation between the motion image 1 and the still image group 74, related information showing a relation between the motion image 2 and the still image group 75, and related information showing a relation between the motion image 3 and the still image group 76 are written
