摘要： Introduced in an image data encoding device is a logic-memory combined chip in which a memory device and a signal processing device are combined. A logic part and a memory part can be connected to each other with a wide bus, allowing to improve processing capability of data transfer. However, the memory part of the logic-memory combined chip has a small capacity, so that an attempt to increase the capacity will lead to upsizing of the chip, resulting in an increase in costs. Therefore, in a processing that data transfer results in bottlenecks (i.e., motion search), image data is transferred to/from an internal memory capable of transferring data at high speed. In a processing that high-speed data transfer is not required, image data is transferred to/from an external memory.

摘要： When the CPU writes data into a memory, a 0 detection circuit detects the number of bits having the value 0 from the data. When the number of bits with 0 is equal to or larger than the number of bits with 1, the data output from the CPU is provided to the memory under control of a selector. When the number of bits with 0 is fewer than the number of bits with 1, the data output from the CPU is inverted and provided to the memory under control of the selector. Accordingly, the rewriting frequency of each memory cell from 0 to 1 or from 1 to 0 in the memory can be reduced in average. Thus the power consumption of the memory in a data writing mode can be reduced.
摘要翻译：当CPU将数据写入存储器时，0检测电路从数据中检测出具有值0的位数。当具有0的比特数等于或大于具有1的比特数时，在选择器的控制下，从CPU输出的数据被提供给存储器。当具有0的比特数少于具有1的比特数时，从CPU输出的数据被反转，并在选择器的控制下提供给存储器。因此，可以平均地减少存储器中的每个存储单元从0到1或从1到0的重写频率。因此，可以减少数据写入模式中的存储器的功耗。

摘要： The control circuit controls output of template block data held in the input section such that a plurality of operation units within the operation section are provided with data of unadjacent template blocks that are different from each other. The operation units within the operation section detect motion vectors according to the template block data provided thereto. Thus, motion vector detection in the template blocks except for those in a region on a display screen requiring no motion vector detection is distributed in the plurality of operation units. Accordingly, the motion vector search can be performed in a wider range in a vertical or horizontal direction than in the conventional case within the same operation time.
摘要翻译：控制电路控制保持在输入部分中的模板块数据的输出，使得操作部分内的多个操作单元被提供有彼此不同的不相邻模板块的数据。操作部分内的操作单元根据提供给它的模板块数据来检测运动矢量。因此，除了不需要运动矢量检测的显示画面上的区域中的模板块中的运动矢量检测分布在多个运算单元中。因此，在相同的动作时间内，与现有的情况相比，可以在比垂直方向或水平方向更宽的范围内进行运动矢量搜索。

摘要： An overall motion detecting device (1) includes a search region variable-shaped motion detector (2) and an overall motion information generator (3). The overall motion information generator (3) controls a surveillance camera (5) which is an external image capturing system and supplies control information of the surveillance camera (5) (such as moving direction, angular speed and focal length) to the search region variable-shaped motion detector (2) as overall motion information (S3). The search region variable-shaped motion detector (2) calculates a motion vector (mv) while renewing, by picture, a search region having a search shape determined by the overall motion information (S3) and a region area suitable for its operational capability.
