PURPOSE: A method for post-processing a decoded image of a mobile phone is provided to decode an image signal of a current frame without using a separate frame buffer for post-processing by storing a post-processed image signal in a frame buffer in which an image signal of a previous frame is stored. CONSTITUTION: A method for post-processing a decoded image of a mobile phone includes first to third steps. In the first step, an image signal of a first frame is stored in a first frame buffer, the image signal is read out for decoding, the decoded image signal is stored in a second frame buffer, the image signal of the first frame is read out from the first frame buffer for post-processing, and the post-processed image signal is stored in the first frame buffer. In the second step, the image signal of the second frame is read out from the second frame buffer, an image signal of a third frame is decoded, the decoded image signal is stored in the first frame buffer, the image signal of the second frame is read out from the second frame buffer for post-processing, and the post-processed image signal is stored in the second frame buffer. In the third step, the above steps are repeated for an image signal of a next frame. |
