摘要： An image encoding method according to the present invention calculates first difference information of an encoding target block and second difference information of an adjacent block, calculates a difference between the first difference information and the second difference information, and uses an intra mode only for blocks where a residual image noise occurs by selecting the intra mode when the difference is larger than a predetermined threshold, and selecting an inter mode when the difference is smaller than the predetermined threshold.

摘要： A reference picture selection unit compares a predicted inter-coding amount indicating a predicted amount of coding required to perform inter prediction on a coding-target field and a predicted intra-coding amount indicating a predicted amount of coding required to perform intra prediction on the coding-target field. Upon determining that the predicted inter-coding amount is relatively larger than the predicted intra-coding amount, the reference picture selection unit switches the reference picture from a field having the same parity as the coding-target field to a field which is referable and temporally closest to the coding-target field.
摘要翻译：参考图像选择单元将表示在编码对象场上执行帧间预测所需的编码预测量的预测帧间编码量与表示对编码对象区域进行帧内预测所需的编码量的预测帧内编码量进行比较目标字段。在确定预测的帧间编码量相对大于预测的帧内编码量的情况下，参考图像选择单元将参考图像从具有与编码目标区域相同的奇偶校验的场切换到可参考的和时间上的场最接近编码目标字段。

摘要： A still block detector is provided at a stage before a moving image encoder. The still block detector divides a frame to be processed into a plurality of blocks, sorts the blocks in the frame in ascending order of movement amount, and sets the first one or more blocks the number of which is specified by a “corresponding block setting number” input from the outside of an encoding device, to “still blocks.” For the still blocks, the moving image encoder performs an inter-encoding process with respect to a moving image by forcibly setting motion vectors to zeros without performing a motion search or by forcibly setting DCT coefficients to zeros without performing DCT or quantization.
摘要翻译：静止块检测器设置在运动图像编码器之前的阶段。静止块检测器将要处理的帧划分成多个块，按照移动量的升序对帧中的块进行排序，并且通过“对应的块设置号码”来设定其数量的第一个或多个块 “从编码装置的外部输入到”静止块“。对于静止块，运动图像编码器对运动图像执行帧间编码处理，强制将运动矢量设置为零，而不执行运动搜索，通过将DCT系数强制设置为零而不执行DCT或量化。
