Method and apparatus for encoding and decoding image data using run of the image data
An encoding method includes selecting a run detection method in accordance with characteristics of image data, generating a run value by detecting a run that is repeated in the image data in accordance with the selected run detection method, generating run count bits by counting the number of repetitions of the detected run, and performing a run-length encoding using the detected run values and the run count bits. The run detection method includes a coefficient run detection method that detects a run based on pixel values, a pattern run detection method that detects the run based on whether the pixel blocks have a specified pattern, a difference run detection method that detects the run based on a difference value between two successive pixel values, and a residual run detection method that detects the run based on an error value that is a difference value between an actual pixel value and a predicted value.
