    Abstract: PURPOSE: An image encoding method and apparatus and an image decoding method and apparatus are provided to change the pixel value of each pixel inside a prediction block with post-processing depending on a location within the picture of the prediction block and create a new prediction block. CONSTITUTION: A prediction unit creates a first prediction encoding unit for a current encoding unit to be encoded(2110). In case the current encoding unit does not include an area which escapes the boundary of a current picture, a post-processing unit creates a second prediction encoding unit with the change of the pixel value of each pixel(2120,2130). In case the current encoding unit includes the area which escapes the boundary of the current picture, the post-processing unit outputs the first prediction encoding unit as the prediction information of the current encoding unit(2140).

    Abstract: PURPOSE: An image coding method, image encoding method, and apparatus thereof are provided to increase the efficiency of image compression through the process of predicted image data. CONSTITUTION: A first predictive encoding unit is generated by a current encoding unit(2110). A second predictive encoding unit is generated by changing a pixel value of each pixel that consists of a first predictive encoding unit. The difference between a current encoding unit and a second predictive encoding unit is encoded.

    Abstract: PURPOSE: An inverse quantization method of images, an inverse quantization device thereof, a decoding method, and a decoding device thereof are provided to reduce quantization errors which is the differences between values recovered through inverse quantization and original values. CONSTITUTION: An inverse quantization method of images comprises the following steps: a step of extracting a quantization coefficient generated by quantizing a conversion coefficient from encoded bit streams; a step of deciding quantization step revision value for reducing quantization errors; a step of performing inverse quantization using a second quantization step value generated by a first quantization step value for inverse quantization of the quantization coefficient.
