<p>PROBLEM TO BE SOLVED: To reduce the data quantity without causing defects in the processing, to avoid an undesired operation from going ahead of other operations in the case of write and read of data to/from different banks, and to prevent a displayed image from being disturbed. SOLUTION: When a through-image is outputted to a monitor 44, interleaving processing is applied to high resolution YUV data outputted from a signal processing circuit 22 and low resolution YUV data are generated. The low resolution YUV data are written in one bank formed in an SDRAM in a time of 1/15 see. On the other hand, the low resolution YUV data of a preceding frame are read from the other bank in a time of 1/30 sec. That is, data are read twice in a time of 1/15 sec. The read low resolution YUV data are outputted on a monitor 44 through the on the other hand, by an NTSC encoder 42.</p> |
