PROBLEM TO BE SOLVED: To provide an image processing device capable of improving resolution conversion processing performance.SOLUTION: An image processing device has: a resolution conversion part which performs resolution conversion from a first image to a second image in block units; a fourth acquisition part which acquires a decimal part of the sum of an offset (d0) of a vertical coordinate of a pixel in a final line of last processing object block lines and a vertical inter-pixel distance (H) of the second image as an offset (C1) of a vertical coordinate of a pixel in a top line among block lines of the second image relative to a vertical coordinate of a pixel in the top line among block lines of the first image; and a fifth acquisition part which acquires a vertical coordinate of a pixel in block lines of the second image, based upon an offset (C1) of a vertical coordinate of pixels of the top line, the vertical inter-pixel distance (H) of the second image, and the number of vertical pixels per block of the second image, as to block lines to be processed.SELECTED DRAWING: Figure 3 |
