IMAGE SHARPENING METHOD AND IMAGE PROCESSING DEVICE |
| 摘要 |
An image sharpening method and an image processing device are provided. The method includes: obtaining a plurality of pixels in an image; calculating a first weight of a high pass filter and a second weight of a first filter according to the pixels, and the first filter is a convolution of the high pass filter and a low pass filter; generating a sharpening filter according to the high pass filter, the first weight, the first filter and the second weight; and executing a sharpening operation on the pixels according to the sharpening filter. Accordingly, a sharpened image has better vision effects. |
