Filed: 1994-07-20
Abstract: PURPOSE:To remove the image of a moving body and to correctly recognize the road environment even when the moving body attached to the self vehicle comes within the view of a camera by providing a means removing the image of moving body. CONSTITUTION:The picture data of each picture element line of the picture frame is sent in advance from a TV camera 1 in the order of high-order line. Then they are outputted to a LUT 11 and 1-line delay circuit 7 by one picture element. An edge picture extraction part 2 scans the inputted picture of each line. When the picture element value changes more than the determined value, the change point is taken as an edge at the extraction. The prepared edge picture is outputted to a symbol line recognition part 3. In this case, the picture frame is divided into units called field. The field appears on the screen in succession and they are overlapped to comprise one picture frame. Then, the picture element values at the corresponding position are compared in the successive field. The image of the moving body such as wiper can be removed by taking out the picture element with high picture element value.
