<p>Provided is an image conversion device capable of highly accurate interpolation using an extremely small amount of memory for image conversion processing. The image conversion device converts a first image to a second image and comprises: an image memory unit for storing the first image; a table memory unit for storing a coordinate conversion table comprising reference coordinates, which constitute information regarding positions in the first image used for calculating pixel values for each pixel in the second image and which indicate pixels in the first image, and relative positions (sub-regions) which are produced from said reference coordinates; and an image processor for converting the first image into the second image by calculating the pixel values of the pixels indicated by the reference coordinates of the first image and the pixel values of the pixels in the first image located in the vicinity of the reference coordinates by means of arithmetic expressions corresponding to the relative positions, thereby calculating the pixel values of the pixels in the second image.</p> |
