PROBLEM TO BE SOLVED: To provide an image processor and program for adaptively varying a filter coefficient on the basis of a determination result by determining an edge part from luminance and hue in the case of obtaining RGB data from a Bayer's image. SOLUTION: The image processor is provided with: a means for calculating an interpolation value with respect to RGB data of a target pixel from peripheral pixels in the case of obtaining the RGB data from the Bayer's image; a means for calculating the hue and saturation of the target pixel from the calculated data; a means for comparing hues between the target pixel and the peripheral pixels, determining that the target pixel is a false color when a difference between the both hues exceeds a prescribed value and replacing the hue of the target pixel with the peripheral dominant hue; a means for calculating a filter coefficient on the basis of the target pixel and the hue of the peripheral pixels; and a means for outputting the RGB data on the basis of the filter coefficient, thus the image processor adaptively varies the filter coefficient.
