This invention provides a technique which performs moving image recording and still image recording free from unnatural feeling by positively informing the user of the fact that a still image is sensed during playback of a moving image when a still image is sensed during moving image recording. To this end, when a release switch is pressed to its full stroke position during moving image recording, and a switch SW2 is turned on, a still image is sensed. This still image sensing processing period is divided into a first period and second period. In the first period, a blackout image is generated, and is recorded as a moving image of a first substitute frame period (S432). An image of the sensed still image is recorded as a moving image of a second substitute frame period in the second period.
