ABSTRACT:
An image processing method includes the steps of detecting a dynamic range of input image data, performing resolution conversion processing to increase the number of grayscale levels of the input image data, and performing dithering processing to reduce the number of grayscale levels of each pixel of the input image data. The number of pseudo grayscale levels in the dithering processing is determined, based on a parameter indicating the level of the dynamic range and a parameter concerning the resolution conversion processing.
