Abstract
An image processing device includes an edge-enhancing image enlarger that converts an input image to a high-resolution image with edge enhancement. A difference calculator determines differences between the high-resolution image and the input image. A high-resolution image corrector corrects the high-resolution image by diffusing the differences to pixels of the high-resolution image, thereby generating a corrected image in which edges are enhanced without image degradation in textured areas.
Claims16
An image processing device comprising:
- an edge-enhancing image enlarger for converting an input image having a first resolution to a high-resolution image having a second resolution, edges included in the input image being enhanced in the high-resolution image;
- a difference calculator for determining differences between the high-resolution image and the input image;
- and
- a high-resolution image corrector for correcting the high-resolution image by diffusing the differences to pixels in the high-resolution image, thereby generating a corrected image, and outputting the corrected image as an output image.
An image processing method comprising:
- converting an input image having a first resolution to a high-resolution image having a second resolution, edges included in the input image being enhanced in the high-resolution image;
- determining differences between the high-resolution image and the input image;
- and
- correcting the high-resolution image by diffusing the differences to pixels of the high-resolution image, thereby generating a corrected image, and outputting the corrected image as an output image.
