摘要： In transmitting image data from multiple cameras to an image processing section to produce a synthesized image from respective camera images, the amount of data transmitted through a transmission path can be cut down without sacrificing the quality of the synthesized image. In accordance with a correspondence between the synthesized and camera images as described on a mapping table, a resolution specifier specifies resolutions, which should be necessary for image synthesis, for respective areas of each camera image. A compressor, provided for each of the cameras, compresses the associated camera image data according to the resolutions specified. In this manner, the image data, which has been compressed in accordance with the correspondence between the synthesized and camera images, is transmitted through the transmission path.

摘要： An image motion vector detection apparatus effectively reduces influences of false vectors arising at a certain probability and suppresses time lags. An image fluctuation stabilizer highly stabilizes images or frames without causing unnatural visual feelings. An image motion vector detection apparatus comprises means for detecting motion vectors in each of motion vector detection regions defined in the whole or part of picture frame, means for judging the reliability of the motion vector in each region, and signal processing means which, in obtaining a motion vector of the whole or part of the frame from the motion vectors of the regions and in case the number of motion vectors judged to be reliable is more than or equal to a predetermined number, outputs a representative value of a set of the reliable motion vectors as a motion vector of the frame.

摘要： An image pickup device is provided which includes an image pickup unit, a fluctuation stabilizer, an exposure time controller, and a computing unit. The image pickup unit sends a video signal to the fluctuation stabilizer in which unnecessary fluctuations of the image output by the image pickup unit are stabilized depending on a stabilization reference value. The exposure time controller serves to control an exposure time used for the image pickup unit depending on the exposure time reference value. The computing unit functions to compute the stabilization reference value and the exposure time reference value. Such image pickup device produces an improved visually natural image.

摘要： In an image processor for synthesizing images that have been taken by multiple cameras mounted on a vehicle, even if any movable part of the vehicle has changed its state, the synthesized image will have no unnatural part. A pixel synthesizer receives the images that have been captured by the cameras included in an imaging section and generates the synthesized image by reference to a mapping table. Receiving a signal indicative of the state of a movable part such as the door or hood of the vehicle, a display mode changer disables at least one of the cameras that is taking an image to be affected by any change in the state of the movable part. For that purpose, the changer rewrites mapping data stored on the mapping table and thereby eliminates the image in question from the synthesized image.

摘要： A correlation computing device includes a higher-order bit elimination circuit which receives a digital input image signal and provides an output signal in which higher-order bits up to 50% have been eliminated as a maximum word length of a digital input image signal. A representative point preservation memory temporarily stores the output signal from the higher-order bit elimination circuit. A correlation determining circuit determines a correlation between a signal stored in the representative point preservation memory and the output signal from the higher-order bit elimination circuit. A minimum-value address decision circuit selects a minimum value of the correlation determined by the correlation determining circuit and determines a motion vector for the digital input image signal.
