    摘要: In a video coding/decoding system, a high-resolution reference image having pixels in closer relation is produced by applying the interpolating operation of a luminance value to a reference image. In the matching process for motion estimation, when the luminance value of a point lacking a pixel in the reference image becomes required, the luminance value of a pixel at a point nearest to the high-resolution reference image is approximated without computing the interpolation. As a result, the number of times the interpolation of the luminance value is computed can be reduced, thereby reducing the circuit scale or the processing time. Also, the horizontal and vertical components of the motion vector of each pixel used for synthesizing a predicted image are defined to assume only a value equal to an integer multiple of 1/d1 and 1/d2 (d1 and d2 being positive integers) of the distance between adjacent pixels. Consequently, a mismatch of a predicted image attributable to the difference of the computation accuracy of the motion vector in a simple computation is prevented thereby to simplify the process.

    摘要: An electronic control system which electronically controls the air fuel ratio of a mixture being supplied to a gasoline engine in highlands. An orifice device is provided in a passage through which secondary air is supplied to the venturi section of the engine carburetor. An electronic control unit carries out programmed control of the orifice opening of the orifice device in response to the atmospheric pressure and the engine temperature to create a reference pressure. A further electronic control unit drives a second air control valve provided in the secondary air supply passage along a predetermined operating characteristic pattern in response to the difference between the reference pressure and an actual pressure present in the venturi section of the carburetor. A mixture having an optimum air fuel ratio corresponding to the atmospheric pressure can thus be supplied to the engine from the carburetor.

    摘要: A compressed dynamic image encoding device is provided, in which a motion vector is generated by searching a reference image for an image area most similar to an image area of a video input signal; a motion-compensated reference image is generated from the motion vector and the reference image; a prediction residual is generated, by subtracting the motion-compensated reference image from the video input signal; the reference image is generated, by adding the motion-compensated reference image and the result of processing performed to the prediction residual; and an encoded video output signal is generated by the processing performed to the prediction residual. The reference image comprises on-screen reference images, located inside a video display screen, and an off-screen reference image located outside the video display screen, and the off-screen reference image is generated based on the positional relationship of plural similar reference images of the on-screen reference images.
