    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： 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： In the vehicle surroundings display device of the invention, an image processor generates an image showing the situation around a vehicle. When an obstacle is detected by an obstacle detection means, the image processor determines an image missing region using the position of the border of the obstacle on the vehicle side detected by an obstacle position detection means and fills the image missing region with substitute image data. This eliminates unnaturalness of a display image the user may feel and enables the user to accurately recognize the position of a neighboring obstacle that is important in driving operation.
