Weighted image enhancement method |
摘要 |
A weighted image enhancement method includes receiving an original image. The original image includes several original pixels. The original image is sharpened to generate a sharpened image. The sharpened image includes several sharpened pixels. Edge detection is performed with respect to the original image to generate a probability of whether each original pixel is on an edge. An enhancement mode setting is received. A corresponding weight table corresponding to the enhancement mode setting is looked up to obtain a corresponding enhancement weight of each original pixel according to the probability of whether each original pixel is on an edge. A weight calculation is performed utilizing each original pixel and its corresponding sharpened pixel according to its corresponding enhancement weight to generate an enhanced image. The enhanced image is displayed by a display unit. |

1. A weighted image enhancement method comprising:
(a) receiving an original image, wherein the original image comprises a plurality of original pixels; (b) sharpening the original image to generate a sharpened image, wherein the sharpened image comprises a plurality of sharpened pixels; (c) performing edge detection with respect to the original image to generate a probability value corresponding to whether each original pixel is on an edge; (d) receiving an enhancement mode setting; (e) looking up a corresponding weight table corresponding to the enhancement mode setting to obtain a corresponding enhancement weight of each original pixel according to the probability of whether each original pixel is on an edge; (f) performing a weight calculation utilizing each original pixel and its corresponding sharpened pixel according to its corresponding enhancement weight to generate an enhanced image; and (g) displaying the enhanced image by a display unit. |
