Abstract
The prevent invention can prevent roughness in an image and reduce contouring and coding distortion in the image. The image processing apparatus according to the present invention reduces distortion in an input image, and includes: a masking signal generating unitthat generates a masking signal for reducing the distortion; and a masking signal adding unitthat adds the masking signal to the input image, wherein the masking signal generating unitincludes: a level difference processing unitthat smoothes a level difference between pixel values of pixels in the input image; a difference calculating unitthat calculates a difference between the input image and an image which has been processed by the level difference processing unit; and a random number setting unitthat sets an amplitude, creates a is random number having the set amplitude, the amplitude decreasing, as the difference approaches a predetermined value.
