Abstract: The characteristic of nonlinear processing with respect to image data is designated by a GUI and the result of the processing quickly displayed. A personal computer 72 displays a GUI image for input on a monitor. When a user designates a nonlinear characteristic on the GUI image by an input device 70, the personal computer 72 extracts a break point approximation function indicating the nonlinear characteristic and displays the same in the GUI image. Further, the personal computer 72 generates a program for executing nonlinear processing indicated by the extracted break point approximation function by a linear array type multiple parallel processor (DSP 80) and downloads the generated program to the DSP 80.

Abstract: A parallel processor apparatus which can perform processing with a good efficiency on signals comprised of data of different lengths. A parallel processor configured by a serial connection of a first parallel processor and a second parallel processor having n number of individual processors and (m-n) number of individual processors. For signals comprised of data of a length, serving as the unit of processing, of m or less and n or more, these parallel processors are connected and used as a single parallel processor apparatus which performs processing equivalent to that by a conventional parallel processor apparatus. For signals comprised of data of a length of n or less, these parallel processors are independently used to perform pipeline processing and thereby perform two times the amount of processing of that performed by a conventional parallel processor apparatus.

Abstract: To realize a motion compensation device capable of more appropriately compensating the movement of a video signal subjected to double-speed conversion. A motion vector between an image of a current field in a double-speed-converted video signal and an image of a reference field that is one frame or two frames later is detected, the pixels of the current field are shifted based on the motion vector and the pixels of the reference field are shifted in an opposite direction based on the motion vector. Then simple averaging or weighted average according to the shift amount is performed on the pixels of the current field and the pixels of the reference field to compensate the current field, thereby being capable of compensating the movement between fields so as to be much smoother than conventional cases.

Abstract: PROBLEM TO BE SOLVED: To enable a viewer to correctly grasp the size of an object which is photographed as a merchandise in TV shopping, for example. SOLUTION: At the side of transmission, actual size information X on a picked-up image is measured when the picked-up image of the object being the merchandise is transmitted and the actual size information X on the picked-up image is transmitted together with the image pickup output of the object being the merchandise. At the side of reception, an additional information extracting circuit 25 extracts actual size information X. Then a scaling rate R for the actual size is calculated from display size information Y and actual size information X on the transmitted pickup image. A magnifying and reducing circuit 24 magnifies or reduces a reproduction image based on the scaling rate R and displays it. Thus the object to be the merchandise is displayed by the size being the same as the actual size.

Abstract: PROBLEM TO BE SOLVED: To automatically discriminate an artificial image or a natural image per pixel to select proper image processing. SOLUTION: A delay difference by one line is given to image data, which is inputted into a first correlation calculation part 730a, and 3×3 vicinity pixel is sampled for a judging pixel whose type of image is determined. The number of vicinity pixels in which the determined pixel agrees with the image data is counted, and the counted value is compared with a value of a parameter 1 of a register 728 to perform primary determination of type of image. The results of determination to be given to each pixel are further supplied to a second correlation calculation part 760a to sample 3×3 vicinity pixel for the determined pixel in the same way. The number of types of images in the results of primary determination is counted, and the counted value is compared with a parameter 2 with respect to size to discriminate type of image of the pixel concerning the vicinity pixels in a 3×3 region centered on the determined pixel. The optimum processing is selected in interpolation processing and emphasis processing using the results of determination.

Abstract: PROBLEM TO BE SOLVED: To eliminate granular noise of image data generated from an old film image. SOLUTION: In the S 400, a computer displays a GUI menu for setting a separate point and a graphic curve in the GUI menu is sequentially changed in response to the operation of a mouse by the user. In the S 402, when the operation of the user is finished, the computer receives a separate point corresponding to the curse after the change. In the S 402, the computer extracts a function from a parameter extracted from a separate point. In the S 404, the computer starts a program generating tool and uses a function obtained in the processing in the S 402 to generate a source program for granular noise elimination processing and starts an assembler to compile the program. In the S 406, the computer transfers (down-loads) the generated object program to a DSP.
