Abstract:
1. An image processing circuit for processing an input image, the image processing circuit comprising: a first scaling circuit, for increasing a vertical resolution of the input image to generate a first enlarged image; a plurality of line buffers, coupled to the first scaling circuit, for temporally storing the pixel values of a plurality of pixel rows of the first enlarged image; a first sharpness circuit, coupled to the line buffers, for vertically sharpening the first enlarged image to generate a first sharpened image; a second scaling circuit, coupled to the first sharpness circuit, for increasing a horizontal resolution of the first sharpened image to generate a second enlarged image; and a second sharpness circuit, coupled to the second scaling circuit, for horizontally sharpening the second enlarged image to generate a second sharpened image.
