<p>PROBLEM TO BE SOLVED: To simplify the configuration of a decoder having provision for a large number of the kinds of image formats. SOLUTION: In the case of writing data to either of 1st and 2nd video signal memories 25, 26, data are read from the other memory. Data are written according to an image rate, and data are read according to a frame frequency. The switching of the 1st and 2nd video signal memories 25, 26 is conducted by using a write end detection circuit 21 that detects it such that the data write is completely finished. The write end detection circuit 21 detects the end of data write by counting the number of data to be written in the 1st or 2nd video signal memories 25, 26.</p> |
