Abstract: A method, image processing apparatus, and computer readable medium for image enhancement are provided. In the method, a low-resolution image is received and upscaled to generate an upscaled image having first pixels. Edge detection is performed on the upscaled image to obtain edge information of the first pixels. Each piece of the edge information includes an edge direction and an edge intensity, and each of the edge directions includes a horizontal and vertical component having a constant summation. A non-edge region of the upscaled image is enhanced to generate a high-resolution detail image; based on unsharp masking sharpening methods, an edge region of the low-passed upscaled image is enhanced according to the horizontal and vertical components of the edge directions to generate a high-resolution edge image. Image fusion is performed on the high-resolution edge image and the high-resolution detail image according to the edge intensities to generate a super-resolution image.

Abstract: In a method of driving a flat display having a first pixel and a second pixel, the first pixel is driven to a first gray level and the second pixel is driven to a second gray level during the first sub-frame period of a frame period. The first pixel is driven to a third gray level and the second pixel is driven to a fourth gray level during the second sub-frame period of the frame period. The first gray level is different from the third gray level, with the average value of the first and the third gray level is equal to a first target gray level. The second gray level is different from the fourth gray level, with the average value of the second and the fourth gray level is equal to a second target gray level.

Abstract: In a liquid crystal driving method and circuit, a pixel of a display is driven from an initial pixel value associated with a previous frame to a target pixel value of a current frame by an overdrive gray value. The overdrive gray value is determined by an overdrive curve, the initial pixel value, and the target pixel value. The overdrive curve is simulated from a polynomial function.
