    摘要: A logic circuit outputs a logic signal in response to set inputs and a reset input. This logic signal is applied to output terminals through a latch circuit. When outputs Q and Q of the RS flip-flop maintain a previous state, the latch circuit is activated by a control signal applied from an OR gate to hold a previous logic signal received from the logic circuit. Thus, the logic circuit and latch circuit are arranged on a signal path from input terminals to output terminals. These logic circuit and latch circuit do not include a series connection of transistors and, therefore, is operable at high speed in response to the inputs. Consequently, the outputs Q and Q have excellent response characteristics relative to the set and reset inputs, to enable a high-speed operation.

    摘要: A motion estimation method capable of setting an optimum threshold value and allowing high speed processing includes the steps of: sequentially selecting one of blocks to be searched from a search range; sequentially calculating a difference between corresponding sample values of a reference block and one of blocks to be searched and accumulating an absolute value of difference; comparing an intermediate result of an accumulation value and a prescribed threshold value for a prescribed number of samples and interrupting the step of accumulating the absolute value of difference when the intermediate result exceeds the prescribed threshold value; and making one of blocks to be searched having a minimum final result of the accumulation value correspond to the reference block. The prescribed threshold value is dependent on the reference block. It is noted that the motion estimation apparatus is also disclosed.

    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: A data bus has a bit length of 2 words, and is divided into two bit groups, each of which corresponds to one word. Therefore, the data bus can simultaneously transfer data of two words. A register, a data operation part of a CPU, a RAM and a ROM is connected to the data bus. Even if there is generated data of two words to be transferred in these registers, the data operation part, the RAM and the ROM, the data bus can simultaneously transfer the data. In order to prevent conflict of data on the data bus, there are provided a bus driver, a multiplexer and a bus selector.

    摘要: A processor array includes element processors which are arranged in a matrix in correspondence to respective pixels of a template block, which is a current picture image pixel block. Each element processor stores pixel data of a search window block, which is a corresponding reference picture image pixel block, and obtains an evaluation function value component with respect to the template block pixel data. A summing part sorts the evaluation function components received from the respective element processors of the processor array in accordance with a plurality of predictive modes and sums up the components for the respective sorts, for forming evaluation function values for the respective predictive modes. A comparison part compares the evaluation function values received from the summing part for each predictive mode, to decide a displacement vector providing the best similarity as a motion vector for each predictive mode. It is possible to simultaneously detect motion vectors according to a plurality of predictive modes. It is possible to detect motion vectors employed for moving image predictive compensation in accordance with a plurality of predictive modes at a high speed with a small hardware volume.
