PURPOSE:To attain the data transfer without being limited to a processing speed and the processing timing of a data processor, by writing data with a signal of prescribed period by a storage means provided between two devices. CONSTITUTION:After a video signal for one line's share from an image sensor stored in an RAM4 is read out, when a signal SH is transmitted again from a data processor, the 2nd hand shake control circuit 10 brings the level of a signal READY to high level and inhibits the write of data to the data processor. Further, a clock generator 7 is started, the RAM4 is switched to the write state and the video signal for preceding one line's share of the image sensor 1 stored in a latch buffer 3 is written in the RAM4. |
