Abstract
For always executing an efficient and appropriate error correction process and improving the convenience of the user, an image processing apparatus and a method of the invention enters encoded image data including a marker code for a resynchronizing process within one picture; detects a code error in the encoded image data; and discriminates whether or not to execute an error correction process utilizing the marker code according to a result of the detection and an attribute of the encoded image data.
Claims10
An image processing apparatus comprising:
- a) an input unit arranged to input encoded image data, wherein a code train of said encoded image data includes a marker code for a resynchronizing process within one picture;
- b) a detection unit arranged to detect a code error in the encoded image data;
- and
- c) an error processing unit arranged to detect an error correction process on the encoded image data according a result of detection by said detection unit, wherein said error process unit discriminates whether or not to execute an error correction process utilizing said marker code according to an attribute of the encoded image data.

An image processing method comprising:
- a) an input step of inputting encoded image data, wherein a code train of said encoded image data includes a marker code for a resynchronizing process within one picture;
- b) a detection step of detecting a code error in the encoded image data;
- and
- c) an error processing step of executing an error correction process on the encoded image data according a result of detection in said detection step, wherein said error processing step discriminates whether or not to execute an error correction process utilizing the marker code according to an attribute of the encoded image data.
