Abstract
To suppress influence of a rounding error and acquire a more highly precise filter processing result, by performing convolution processing in order from a divided filter having a smaller sum of filter coefficient among divided filters, shifting a position of the decimal point of a filter processing result in a fixed-point format to generate an intermediate image, integrating the filter processing result having a larger bit width of a decimal part, and substantially reflecting a processing result of the decimal part.
