Abstract: The disclosure provides an image processing apparatus and an operation method thereof. The image processing apparatus includes a sticking model circuit and a dynamic adjustment circuit. The sticking model circuit correspondingly provides degradation information according to pixel data of a current pixel. The dynamic adjustment circuit dynamically adjusts original image data of the current pixel according to the degradation information to generate output data. The dynamic adjustment circuit converts a first sub-pixel of the current pixel to at least one second sub-pixel of the current pixel when luminance is maintained. The dynamic adjustment circuit provides the output data to the sticking model circuit.
