PROBLEM TO BE SOLVED: To reduce blurs and unequalness of the line width of a text, etc., in the case of converting the resolution of a picture. SOLUTION: At the time of N>M (at the time of magnifying the picture) in the case of setting input resolution and output resolution stored in a first memory 11 to be an integral ratio M:N both of which having no common divisor, an arithmetic unit 12 executes first resolution conversion using a nearest interpolation method concerning M-number of pixels and executes second resolution conversion using a linear interpolation method or a tertiary convolution interpolation method concerning N-M-number of pixels. |
