PROBLEM TO BE SOLVED: To provide a picture reducing circuit capable of suppressing the deterioration of a picture by more simple hardware constitution even when a reduction ratio is large and improving the quality of a picture. SOLUTION: In the circuit, a thinning timing generation circuit 102 generates a thinning timing signal PUT for thinning N digital pixel data from M (M=4) continuous digital pixel data based on an N-times (N=2) frequency clock NCLK. Then N digital pixel data thinned based on the signal PUT are respectively stored in 1st and 2nd memories 105, 106 and an weighted mean part 107 finds out the weighted mean of the N stored thinned pixel, data, so that a reduced picture reduced from the input digital pixel data to 1/M can be obtained. |
