MOVING IMAGE RECORDING DEVICE

摘要

A digital video camera (10) includes a CPU (52) mounting a multitasking OS. A plurality of frames of YUV data forming a motion image are recorded in a recording medium (50) in a compressed manner under the control of the CPU 52. Here, a plurality of tasks to be executed by the CPU (52) includes an imaging processing task in relation to a compression process of the plurality frames of the YUV data and a BG processing task in relation to a recording process of a plurality of frames of JPEG data. Furthermore, the imaging processing task includes a determining process for periodically determining a recording processing speed of the JPEG data and a changing process for changing a compression ratio of the YUV data on the basis of the determination result.
