Abstract
The present invention discloses an image processing circuit, wherein the image processing circuit comprises a receiving circuit, a sharpness processing circuit, a luminance variation processing circuit and an output circuit. In the operations of the image processing circuit, the receiving circuit is configured to receive image data; the sharpness processing circuit is configured to perform a high-pass filtering operation on the image data to generate processed image data; the luminance variation processing is configured to determine a high frequency component of each pixel within the image data, and for each pixel, the luminance variation processing circuit is configured to calculate a difference between high frequency components of the pixel and neighboring pixel(s) to generate auxiliary image data; and the output circuit is configured to generate output image according to the processed image data and the auxiliary image data.
