Abstract
According to an embodiment, the invention discusses techniques of encoding image data and decoding the encoded image data in an effective manner. As a result, recording and reproduction of data is optimized by compressing an image signal based on whether or not there exists a significant difference between two adjacent frames or units of image data.
Claims8
A method for decoding coded image data, the method comprising:
- receiving the coded image data, wherein some of the coded image data has an ID indicator that is based on a reference image to detect the reference image based on the ID indicator, and other coded image data does not include the ID indicator that is based on the reference image;
- detecting the reference image based on the ID indicator when the coded image data has the ID indicator that is based on the reference image;
- obtaining moving vector information related to the reference image;
- and
- decoding the coded image data based on the detected reference image and the obtained moving vector information when the coded image data includes the ID indicator, and decoding the coded image data based on itself when the coded image data does not include the ID indicator.

An apparatus for decoding coded image data, the apparatus comprising:
- a receiving unit configured to receive the coded image data, wherein some of the image data has an ID indicator that is based on a reference image to detect the reference image based on the ID indicator, and other coded image data does not include the ID indicator that is based on the reference image;
- a detecting unit configured to detect the reference image based on the ID indicator;
- an obtaining unit configured to obtain moving vector information related to the reference image;
- and
- a decoding unit configured to decode the image data based on the detected reference image and the obtained moving vector information when the coded image data includes the ID indicator, and to decode the coded image data based on itself when the coded image data does not include the ID indicator.
