    Abstract: PURPOSE:To provide a motion vector detector for a picture capable of detecting the motion vector of the picture with high accuracy. CONSTITUTION:A difference between picture data of each picture element of a block of a current frame and picture data of representative point picture elements of a preceding frame read from a representative point memory 11 is detected by a subtractor circuit 12 and a correlation integration list is generated by a correlation integration list generating circuit 13. A motion vector estimating circuit 14 obtains a coordinate in the middle corresponding to a minimum value of an nth order curved face including the minimum correlation integration value of the coordinate of the minimum correlation integration value of the correlation integration list with respect to a circumferential coordinate to estimate the motion vector.

    Abstract: PURPOSE:To quickly decide the camera jiggle of an image by dividing an image covering a single field into plural blocks and checking whether a motion vector is caused by the camera jiggle or not based on the inter-field correlation of the image data on each of plural key point picture element of each block. CONSTITUTION:A key point memory 11 stores the image data on the key point picture element of each of blocks divided from an image covering a single field. The field differential absolute value that is obtained as the subtraction output data on a subtractor circuit 12 is supplied to a correlative integration value production circuit 13. The correlative integration value produced by the circuit 13 is supplied to a motion vector detection circuit 14 and then to a condition deciding circuit 23. The decision output of the circuit 23 is inputted to a frequency distribution production circuit 24. A camera jiggle deciding circuit 25 decides that the motion vector is caused by the camera jiggle if the frequency value of the coordinates corresponding to the motion vector of the image detected by a vector detection part 10 is smaller than a prescribed level in regard of a frequency distribution table produced by the circuit 24.

    Abstract: PURPOSE:To provide the motion vector detector for image which is enable to detect the motion vectors of images with high accuracy. CONSTITUTION:The motion vector of the image between one-fields is detected by a first representative point memory FM1, first subtraction circuit SUB1 and a first motion vector detection circuit DET1, and the motion vector of the image between two-fields is detected by a second representative point memory FM2, second subtraction circuit SUB2 and a second motion vector detection circuit DET2. Then, a motion vector synthesizing circuit SYN outputs a motion vector adding and synthesizing the respective motion vectors at a ratio k:k-1 corresponding to a detecting output (k) due to an acceleration detection circuit ACD to detect acceleration for the motion of the image based on the respective motion vectors.

    Abstract: PURPOSE:To provide methods and devices for variable run length encoding and decoding which have a high encoding efficiency with simple procedures and device constitution. CONSTITUTION:A coefficient 0 detecting circuit 140 detects that an input coefficient is O, and a run (0) generating circuit 141 generates a run code corresponding to continuous coefficient 0 in accordance with the control of a control part 146. A coefficient K detecting circuit 142 detects that the inputted coefficient is K, and a run (K) generating circuit 143 generates a run code corresponding to continuous coefficient O. A multiplexing circuit 144 inserts the run code, which is generated in this manner, before the last inputted coefficient and inputs it to a FIFO 145. The control part 146 controls the operation of each part of a run length encoding circuit 14.

    Abstract: PURPOSE:To shorten an arithmetic time by successively comparing the middle calculated results of plural evaluation functions, and moving to the calculation of the new evaluation function between the pre-block and a block to be processed. CONSTITUTION:An input television picture signal is transmitted to a high speed vector detecting circuit 10 and a one frame memory 11. The circuit 10 successively compares an in-block residual absolute value sum as the evaluation function calculated between a reference block at a corresponding spatial position and a block T with the cumulative middle result of the in-block residual absolute value at the time of searching the in-block residual absolute value sum being the evaluation function calculated between the block T and the arbitrary pre- block in a prescribed inspection space I, by referring to a moving vector held in a delay 12 for a reference vector. Then, when the cumulative middle result is more than the in-block residual absolute value sum, the calculation of the in-block residual absolute value sum is stopped, and the calculation of the new in-block residual absolute value sum between the next pre-block in the prescribed inspection space I and the block T is started.

    Abstract: PURPOSE:To surely discriminate whether or not a detected motion vector results from a jiggle. CONSTITUTION:A motion vector detection section 13 detects a motion vector based on a field difference absolute value detected by a field difference detection section 11, a stationary camera scene discrimination section 12 discriminates a stationary camera scene, and a minimum value detection section 14 detects it that an integration of coordinates corresponding to representative point picture elements is a minimum value in relation to a correlation integration table for each macro block. Then a jiggle discrimination section 15 discriminates whether or not the motion vector results from a jiggle based on the discrimination output of the stationary camera scene discrimination section 12 and the detection output of the minimum value detection section 14.
