PURPOSE:To process enormous volume of input image data such as front image data of a traveling vehicle in a short time. CONSTITUTION:Partially hatched images are cut out from the image in each frame outputted from a television camera located at a position in front of a vehicle. The region of the partial image is set such that the image data in front of the vehicle can be obtained continuously based on traveling speed of vehicle, frame frequency of television camera, view angle of the television camera, and the like. Thus cut out partial image is then cut off at ceiling parts S, S' and subjected to conversion such that a left ceiling part A1, left side face part B, floor part C, right side face part D, and right ceiling part Aa are arranged linearly thus creating a wall face developing image 2. Since only partial images are processed, volume of image data to be processed can be reduced drastically.
