    摘要: A picture signal processing device for performing picture signal processing such as conversion of the number of pixels or conversion processing for the number of scanning lines. The picture signal processing device includes a plurality of element processors and a controller for performing common control of said element processors. The element processors arrayed in association with pixels arrayed in one-dimensional direction of a digitized two-dimensional picture. The pixels arrayed in one-dimensional direction are chronologically sequentially entered to the element processors. Each element processor includes a transient memory for transiently storing pixel data, an input pixel data memory for storing input pixel data for transfer to the transient memory, a pixel attribute information memory for storing the pixel attribute information representing the attribute of pixels, a pixel skip information memory for storing the pixel skip information for skipping pixel data, an arithmetic-logic device for carrying out pre-set calculations using the input pixel data or pixel data of near-by element processors based on the pixel attribute information, and an output pixel data memory for storing and outputting the pixel data taken out from the transient memory. The picture signal processing device can cope with conversion processing at an optional ratio.

    摘要: The present invention relates to an image processing device for converting the number of pixels or scanning lines. In particular, the image processing device according to the present invention comprises an operator for carrying out interpolation operations and a memory for storing filter coefficient sets utilized in the interpolation operations. The memory stores filter coefficient sets each corresponding to each of the phases when the pixel interval of the original image is divided by a prescribed dividing number. Out of these filter coefficient sets, a filter coefficient set that corresponds to the phase closest to that of the pixel data to undergo interpolation operations is then outputted to the operator. The operator then carries out interpolation operations on the pixel data using these filter coefficient sets so that arbitrary format conversion becomes possible.

    摘要: A digital signal processing apparatus and information processing system provide sufficient arithmetic operation performance to process high rate signals in real time and high programming performance to deal with various applications. A group of processor elements is constituted by individual processor elements each formed by disposing an arithmetic and logic unit on the bit lines of a multiport memory wherein their number is equal to or larger than the number of the data bits in a series of serial data, and the plurality of processor elements constituting the group of processor elements are uniformly controlled by controllers mounted on the same silicon chip. Consequently, the multiport memory functioning as a buffer for input data and the arithmetic and logic unit are closely joined together, so data can be communicated smoothly between them. Since the plurality of processor elements are controlled by a single controller so as to operate as a parallel computer, a digital signal processor with a high processing speed can be implemented.

    摘要: 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.

    摘要: A digital video signal processor using parallel processing includes an input serial-access memory having memory cells in which data is inputted into successive ones of the memory cells in response to a programmed-controlled pointer and a three or more port data memory unit for writing-in data read out from the serial-access memory. An arithmetic logic unit responds to stored-program control to read out data from the data memory, perform a program-prescribed arithmetic operation, and write the result of the arithmetic operation back to the data memory. An output serial-access memory is controlled so that the arithmetic result will be outputted under program control in a sequential manner. Operation of the interconnected components is effected by a stored-program control unit connected to the input serial-access memory, the data memory, the arithmetic logic unit, and the output serial-access memory.

    摘要: 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.
