PURPOSE: To provide a picture processor for inhibiting the omission of thin lines or the like at the time of reduction processing of picture data and inhibiting the degradation of the picture quality of reduced pictures. CONSTITUTION: A CPU 1 performs the high resolution conversion of the picture data of line data extended in the horizontal scanning direction and vertical pixel data extended in the vertical scanning direction corresponding to a program inside a ROM 2. Then, the CPU 1 thins out one of the same continuous data among the pixel data of the line data and the vertical pixel data based on the output of clock signals S1 and S2 from a thinning-out clock generation circuit 10. Then, low resolution conversion is performed. The ratio of conversion at the time is the reverse of the previously performed high resolution conversion. |
