Original Abstract Submitted
The present invention provides an image encoding apparatus for encoding a sequence of images, where the apparatus comprises a prediction unit which generates, for a target block to be encoded having a predetermined size in an image, a predicted image from both an intra-prediction image and an inter-prediction image, and obtains prediction errors that are differences between the target block and the predicted image; a transform unit which frequency-transforms the prediction errors, a quantization unit which quantize, using a quantization matrix, the transform coefficients, and an encoding unit which entropy-encodes quantized transform coefficients, wherein the quantization unit obtains the quantization matrix, using at least one of a predetermined quantization matrix for the intra-prediction and a predetermined quantization matrix for inter-prediction.
