PROBLEM TO BE SOLVED: To make it possible to optionally set up the number of video data sequences prepared from a video data sequence for one inputted horizontal scanning line and to be improved in resolution without changing the circuit constitution. SOLUTION: The processor consists of memories 21, 22 for storing a video data sequence for one horizontal scanning line (1H), a control circuit 15 for alternately writing inputted video data sequences in respective memories 21, 22 in each 1H and controlling reading of data from the memories 21, 22 and a mixer circuit 23 for mixing video data sequences read out from respective memories 21, 22 by using a coefficient and preparing a video data sequence for 1H. The control circuit 15 repeatedly reads out video data sequences from the memories 21, 22 plural times within a time corresponding to the 1H obtained at the time of inputting video data sequences and changes the coefficient in each reading of a video data sequence. |
