IMAGE SHARPENING METHOD AND DEVICE, AND SHOOTING TERMINAL

摘要

Embodiments of the present invention provide an image sharpening processing method and apparatus, and a shooting terminal, where the method includes: acquiring to-be-processed image information; performing edge-preserving filtering processing on the image information to obtain base image information and detail image information, where the base image information includes image edge information; determining, according to the image edge information, a sharpening gain required for performing sharpening processing on the detail image information; and performing sharpening processing on the detail image information by using the sharpening gain. It is implemented that the sharpening gain required for sharpening processing is determined by the image edge information, thereby suppressing noise amplification and avoiding generating a phenomenon of overshoot for sharpened image information and improving quality of a sharpened image.
