Title: IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, IMAGE-PROCESSING PROGRAM RECORDED MEDIUM
Abstract:
From the luminance A of a pixel (205) being presently dealt with, the luminance B of the pixel (202) up adjacent to the pixel (205), the luminance C of the pixel (208) down adjacent to the pixel (205), the luminance D of the pixel (204) left adjacent to the pixel (205), the luminance E of the pixel (206) right adjacent to the pixel (205), and the position (i, j) of the next pixel (210), the luminance F of the next pixel (210) is given by F = A+(i/2)(E-D)+(j/2)(C-B). When a low-resolution image is converted to a high-resolution image, the computational complexity is low, and the processing rate is high, thereby forming a sharp image.
