Abstract: An image processing apparatus and an image processing method are provided. The image processing apparatus includes a first memory, a plurality of image processing circuits, a first image processing circuit and dithering circuit. The first memory is utilized for storing an input frame. The image processing circuits are utilized for sequentially performing respective image processing operations on the input frame to generate a first intermediate frame. The first image processing circuit is utilized for performing a first image processing operation on the first intermediate frame to generate a second intermediate frame and writing the second intermediate frame into the first memory. The dithering circuit is utilized for performing a dithering operation on the second intermediate frame transmitted from the first image processing circuit to generate a first output frame and performing the dithering operation on the second intermediate frame read from the first memory to generate a second output frame.
