Abstract
A circuit and a method for processing an image are provided. The circuit includes a weighting circuit and a sharpening circuit. The weighting circuit includes at least two adapters and a weight decider. The weighting circuit receives an input image. Each of the adapters respectively generates a weight according to an image property of the input image. The weight decider performs a logical calculation according to the weights generated by the adapters to generate a total weight. The sharpening circuit performs an image sharpening process on the input image according to the total weight to generate an output image.
Claims26
An image processing circuit, comprising:
- a weighting circuit, comprising:
- a first adapter, for receiving an input image and generating a first weight according to a first image property of the input image;
- a second adapter, for receiving the input image and generating a second weight according to a second image property of the input image;
- and
- a weight decider, coupled to the first adapter and the second adapter, for generating a total weight according to the first weight and the second weight;
- and
- a sharpening circuit, coupled to the weighting circuit, for performing an image sharpening process on the input image according to the total weight to generate an output image.
An image processing method, comprising:
- receiving an input image, and generating a plurality of weights according to a plurality of image properties of a plurality of pixels in the input image;
- performing a logical calculation according to the weights to generate a total weight;
- and
- performing an image sharpening process on the input image according to the total weight to generate an output image,
- wherein each of the weights is generated according to a corresponding image property among the image properties.
