Abstract
A display driver circuit includes a receiver that receives a still image or a moving image, a frame buffer that stores the still image received by the receiver in a still image mode, an image processor that performs an image enhancement operation on the moving image transferred from the receiver or the still image transferred from the frame buffer, and a motion processor that performs a motion compensation operation using a current frame output from the image processor and a previous frame stored in the frame buffer in a moving image mode. The previous frame is data which, in the moving image mode, are processed by the image processor before the current frame and are then stored in the frame buffer. The previous frame is output from the frame buffer to the motion processor in synchronization with the current frame.
