The invention relates to a camera surround view system for a vehicle, comprising at least one vehicle camera which supplies camera images that are processed by a data processing unit in order to generate an image of the surroundings, said image of the surroundings being displayed on a display unit. The data processing unit re-projects textures, which are detected by the vehicle camera, on an adaptive re-projection surface, which is similar to the area surrounding the vehicle, said re-projection surface being calculated on the basis of sensor data provided by vehicle sensors. The data processing unit adapts the re-projection surface depending on a position and an orientation of a virtual camera.

Display apparatus and method for controlling the display apparatus

An image recognition unit recognizes an object in each image captured by a plurality of imaging devices each imaging a partial overlapped imaging region surrounding a vehicle. An image synthesis unit generates a synthesized image by partially overlapping and joining converted images viewed from preset virtual viewpoints, when an imaging region including the recognized object is an overlapping region of which any one of two imaging devices performs imaging. The image synthesis unit synthesizes each converted image area in the overlapping image regions, using a preset blend ratio when an image of the converted images which are joined to partially overlap is generated. An image-setting unit sets the blend ratio of each converted image in the overlapping image regions for recognition results of an object, and a driving support image synthesized with the set blend ratio is output to a display apparatus.
