  • Publication number: 20110182343
    Abstract: An average quantization error value of each of I, P, and B pictures in an encoded unit of processing is calculated as an actually measured value having a large variation. An average quantization error value of each of I, P, and B pictures in an uncoded unit of processing is set as a target value having a small variation. In the encoding of the uncoded unit of processing, a result of the encoding of the encoded unit of processing is referenced and fed back thereto. By uniformly setting respective quantization errors of images and further by uniformly setting the respective qualities of the images, the image quality of a whole stream can be subjectively improved. Since the prefetch of the uncoded unit of processing is not needed, it is possible to perform real-time processing without any increase in the circuit scale.
