Abstract

PURPOSE: To obtain a natural block color picture by deciding the color for coloring the block by using the histogram of the color and coloring.
CONSTITUTION: A color information table forming circuit 2 reads the contents of a picture memory for the block unit and processes. Since the picture memory 1 cannot read color data in the direction of a depth with respect to a specific picture element at the same time in case of reading the picture data of the block for the reason why four layers of R, G, B, Y are present in the direction of the depth, it forms a color information table so as to operate the color data of the picture element at the same time. The color data of the color information table formed by the color information table forming circuit 2 is read for the picture element by a color information reading circuit 3 and outputted to a color information identification circuit 4. In the color information identification circuit 4, a picture element color is discriminated based on the values of R, G, B, Y outputted at every picture element and one color of 16 colors represented by 4 bits of R, G, B, Y is selected. In a color distribution detecting circuit 6, the value counted for the color in the same color counting circuit 5 is received, the histogram of the color used in the block is detected, and the block is colored by the use of the color high in the histogram.
