1. A still frame image decoding method, comprising:
decoding a first frame in first video data of a plurality of video data according to a reference frame at a reference location of a memory, and storing the first frame to the reference location to overwrite at least one part of the reference frame;
selecting the first video data from the plurality of video data and decoding a second frame in the first video data according to the first frame at the reference location in response to a still frame command;
adjusting the second frame, and storing the adjusted second frame to an output location of the memory;
preserving the first frame at the reference location in response to the still frame command, so as to again decode the second frame according to the first frame at the reference location; and
again decoding the second frame according to the first frame at the reference location in response to an end command, so as to store the second frame to the reference location to overwrite at least one part of the first frame.
