IMAGE PROCESSOR AND IMAGE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce the entire computing time in an image processor for magnifying an image by using a TV regularization method.

SOLUTION: The image processor includes: a TV regularization magnifier 5 for acquiring a magnified frame component from an input image; a downsampling part 7 for downsampling the magnified frame component acquired by the TV regularization magnifier to acquire a frame component to be an image of a sample number equal to that of the input image; a subtracting part 6 for subtracting the frame component acquired by the downsampling part 7 from the input image to obtain a texture component; a linear interpolation magnifier 8 for acquiring a magnified texture component from the texture component acquired by the subtracting part 6 by using linear interpolation; and a component combining part 9 for combining the magnified frame component acquired by the TV regularization magnifier 5 and the magnified texture component acquired by the linear interpolation magnifier 8 to acquire a magnified output image.
