摘要： PROBLEM TO BE SOLVED: To solve the problem that deterioration in the image quality due to quantization is conspicuous in a comparatively wide area with less color variation.
SOLUTION: An image correction section 70 increases the gradation, in terms of expression, of an image region with a comparatively large area whose pixel values are not much changed in advance. Even when a quantization section 30 applies quantization to the region, since the expressional gradation, i.e. the number of bits is sufficiently maintained, the deterioration in the image quality due to the quantization can be reduced as a result. Conversely, further data reduction is attained for image regions wherein the deterioration in the image quality due to the quantization is not significant.

摘要： PROBLEM TO BE SOLVED: To reduce operational throughput for calculating the feature value of an image used for quantization control when encoding a moving picture. SOLUTION: When encoding an I picture in an original image memory 1, a feature value arithmetic part 16 calculates a variance value for each MB, stores it in a feature value storage memory 19, calculates quantization step size information of the MB and sends it to a quantization control part 13. When encoding the P picture, a feature value prediction part 17 acquires the variance value of MB of the I or P picture that becomes the predictive image of the MB, from the featured value storage memory 19, calculates the variance value, stores it in the featured value storage memory 19, calculates quantization step size information, and sends it to the quantization control part 13. When encoding the B picture, the feature value prediction part 17 also acquires the variance value of MB of the I or P picture that becomes the predictive image of MB of the B picture, from the feature value storage memory 19, calculates the variance value, calculates a quantization step size, and sends it to the quantization control part 13.

摘要： PROBLEM TO BE SOLVED: To lessen an increase in an operation quantity or overhead of encoded data and remarkably improve prediction efficiency for, especially, a fading image with which a conventional dynamic image coding method such as MPEG cannot deal with in encoding and decoding dynamic images. SOLUTION: Moving compensation prediction inter-frame encoding is performed for encoding target macroblocks of the dynamic image, by using at least one reference frame past in time and using a moving vector between the encoding target macroblock and the reference frame. In this case, the moving compensation prediction inter-frame encoding is performed by switching for each of encoding target macroblocks, in-between using the moving vector of the decoding target macroblock having the same in-frame position, as that of the encoding target macroblock in an encoded frame immediately before an encoding target frame including the encoding target macroblock, and deciding a new moving vector to perform encoding.

摘要翻译：要解决的问题：为了减少编码数据的操作量或开销的增加，并且显着地提高了预测效率，特别是对于诸如MPEG的常规动态图像编码方法在编码中不能处理的衰落图像，以及解码动态图像。解决方案：通过使用过去的至少一个参考帧并使用编码对象宏块和参考帧之间的移动矢量来执行移动补偿预测帧间编码，以对动态图像的目标宏块进行编码。在这种情况下，通过使用具有相同帧内位置的解码目标宏块的移动矢量之间的编码对象宏块的编码对象宏块的编码对象宏块的编码目标宏块的切换来进行移动补偿预测帧间编码在紧邻编码目标帧包括编码目标宏块之前的编码帧中，并且确定新的移动矢量以执行编码。版权所有（C）2007，JPO＆INPIT
