Abstract: In an imaging device or an imaging system, it becomes possible to generate a moving image file in which audio and a moving image are synchronized with each other even if moving image capturing is started from the middle of music. Upon receiving an operation input for audio reproduction execution, the imaging device causes an audio decoder to execute an operation, and outputs audio data to a speaker. At this time, a reproduction position in audio coded data is calculated, and reproduction position data is sent to a multiplexer. Upon receiving an operation input for moving image capturing execution, a moving image encoder and the multiplexer are caused to execute operations. The multiplexer multiplexes the reproduction position data to moving image coded data and the audio coded data, to generate a moving image file.
