PURPOSE:To provide an image processor converting color image information of low resolution into image information of high resolution without blurring an edge and image quality. CONSTITUTION:Inputted color space is converted into color space which is capable of resolving luminance and color difference components by a RGB-YUV convertion circuit 1, the edge information of the color difference components is prepared based on the edge information of the luminance components in a color difference edge preparation part 3, the edge preparation of the only luminance components is performed in a luminance edge preparation part 2, the edge is converted into the original color space in a YUV-RGB conversion circuit 4 and the space is outputted. Therefore, the color image information of low resolution can be converted into the information of high resolution without blurring an edge part and image quality. Further, the color slippage due to the deviation of the edge preparation in each color is eliminated and excellent high resolution can be prepared. |
