Abstract: An image processing method applied in an image processor for processing an image including first pixels each having a corresponding pixel value. The pixel values of first pixels are distributed within a first distribution range. Second pixels comprise a region and are obtained from first pixels when a difference between pixel values of adjacent second pixels is less than a predetermined value. Gained pixel values are obtained after applying a gain to the image. An amount of distortion is obtained by summing up weighted differences between a reference pixel value and gained pixel value of first pixels having gained pixel value not distributed within first distribution range. A weighting factor does not equal to 1 when first pixel is within the region, and equals to 1 when first pixel is outside the region. The gain is updated according to the distortion. Processed image is obtained by applying the updated gain.

Abstract: A method of frame interpolation for frame rate up conversion method is provided. The method includes: determining a first adjusting value and a second adjusting value according to a target pixel in at least one of a first frame and a second frame; determining an interpolated pixel value of the target pixel in an interpolated frame between the first frame and the second frame according to the first adjusting value and a pixel value of the target pixel in one of the first and second frames; and adjusting a pixel value of the target pixel in one of the first and second frames according to the second adjusting value.
