Before a moving image is picked up, a data write speed of set recording media 20 is measured or acquired (steps S2-S5, S6). The speed performance of the recording media (represented by “high”, “medium” and “low”) is determined based on the measured or acquired data write speed (step S7). In the moving-image pickup, when the determined write speed performances are low, medium and high, respectively, control passes to a buffer data lump recording mode, a ring buffer recording mode and a stream recording mode, respectively, and then the moving-image data is recorded on recording media 20 in different moving-image recording methods (steps S11, S12 and S13), respectively. Thus, the settable upper limit of recording quality need not be set to that of recording media having low write speed performance.
