Abstract:
1. An image processing device configured to display on a display screen, an image of corresponding surroundings of a vehicle, wherein the image processing device comprises: at least one image capturing camera, wherein each corresponding one image capturing cameras captures images of the corresponding surroundings of the vehicle and generates a corresponding plurality of frames of image data belonging to the corresponding one image capturing camera; a control unit; a viewpoint converter, in the control unit, configured to perform viewpoint conversion on the image data to generate a viewpoint-converted image belonging to the corresponding one image capturing camera having a point of view looking downwardly from above the vehicle; a solid object extractor, in the control unit, configured to extract an outline of a solid object belonging to the corresponding one image capturing camera based on inter-frame differences from the corresponding frames of image data when there is relative motion between the vehicle and the solid object, wherein the solid object extractor further extracts at least one of a moving direction, a size, and a distance from the vehicle to the solid object; a solid object image generator, in the control unit, configured to generate a solid object image belonging to the corresponding one image capturing camera based on the extracted outline of the solid object, wherein the solid object image generator generates the solid object image in accordance with at least one of the extracted moving direction, the size, and the distance from the vehicle to the solid object; an image synthesizer, in the control unit, configured to synthesize a display image belonging to the corresponding one image capturing camera based on the generated solid object image and the viewpoint-converted image, wherein the image synthesizer determines the direction and the size of the solid object image in accordance with at least one of the moving direction, the size, and the distance from the vehicle to the solid object extracted by the solid object extractor; and a display controller, coupled to the control unit, configured to display on the display screen at least the display image belonging to the corresponding one image capturing camera synthesized by the image synthesizer.
