Abstract

An image processor includes: a decimal point position determining unit; an image inputting unit; and a calculating unit. The decimal point position determining unit determines a position of a decimal point based on a size of a mask that has a plurality of filter coefficients. The image inputting unit receives image data indicative of an image having a plurality of pixels, the image data including a pixel value for each pixel. The calculating unit performs, while setting a decimal point to be fixed at the determined position, a convolution operation on a pixel value of each pixel and pixel values of peripheral pixels for the each pixel by using the filter coefficients of the mask to find an average peripheral pixel value for the each pixel.
