Summary:To provide an apparatus for generating interpolation pixels to be supplied to a matrix-type display capable of upscaling images so that the contours of characters, for example, on the display may not so conspicuously blurred even if an upscaling rate gets higher. In order to achieve this object, an interpolation curve producing part 20 produces an interpolation curve having a pair of original pixels at ends, and is sloped gradual in the vicinity of the ends but otherwise steep. An interpolation curve deforming part 21 preferably so deforms the interpolation curve, according to the image upscaling rate, that the slope for the section not in the vicinity of the ends gets steeper as the upscaling rate for images gets higher. By using the deformed interpolation curve, an interpolation pixel calculating part 22 calculates an interpolation pixel(s) for interpolation between the pair of original pixels.
