Abstract:
An imaging unit outputs a video signal at a frame rate higher than a standard frame rate. During a zoom operation period or a period including the zoom operation period and periods before and after the zoom operation, a video signal from the imaging unit is recorded in a recording medium at a high recording frame rate. Other than this period, a video signal is recorded in the recording medium at the standard frame rate. The recording frame rate and zoom operation information is recorded as metadata in the recording medium. During reproduction, based on a set reproduction mode, thinning processing is carried out on a video signal recorded during a zoom operation, and the processed signal is output at the standard frame rate. In this way, it is possible to change a frame rate in view of a photographer's intention and assure compatibility with existing viewing and reproduction environments.
