An image pickup device is equipped with a function to a pickup still picture during a moving picture pickup operation with voices. After a moving picture pickup processing with voices is started (YES in S2), a moving picture recording processing and a voice recording processing are started (S14). Subsequently, when a shutter button is depressed halfway (YES in S16), the moving picture recording processing is switched to a processing to store substitute frames, which are a copy of frame data immediately preceding the half depression operation of the shutter button, instead of moving picture frames imaged in moving picture frame cycles (step S20), and a still picture pickup processing is performed. After the still picture pickup processing ends, the normal moving picture recording processing is resumed. When a picture recording end button is operated (YES in S17), a moving picture file with voices is created from frame data, which includes substitute frames, and voice data, both of which are accumulated and stored in a buffer memory (S18). As a result, even thought the moving picture pickup operation is interrupted, moving pictures can be recorded as a single moving picture file.
