Abstract: Exemplary embodiments disclose an image processing method which includes obtaining a binary value by quantizing a value obtained by summing at least one pixel value of an input image and a quantization error value of a neighboring pixel; determining a pixel in which a detail intensity is to be inserted according to the binary value of each pixel; determining the detail intensity to be inserted in the determined pixel; and inserting the determined detail intensity in the determined pixel, wherein the quantization error value of the neighboring pixel is a difference value between an original pixel value of the neighboring pixel and a pixel value quantized with respect to a predetermined constant value.

Abstract: An image correction method includes: obtaining information regarding at least one of brightness and colors of pixels constituting an input image, the input image comprising a plurality of regions classified according to whether the at least one of the brightness and the colors of the pixels are substantially uniformly distributed in a corresponding region; determining a weight with respect to at least one pixel based on the obtained information; and correcting the input image with respect to the at least one pixel based on the determined weight.
