Title:
IMAGE DETECTION APPARATUS
Document Type and Number:
Japanese Patent JPH01178810
Kind Code:
A
Abstract:
PURPOSE:To accurately detect an image even in case of rain, by constituting the title apparatus so that the image of the outside is detected through a transparent window held to the state immediately after a bonded substance is removed by a wiper. CONSTITUTION:A unidirectional sensor 3 detects an image outside a case 1 through a transparent window 2 while moves in a predetermined direction within the case 1 while a wiper 5 moves in the state brought into contact with the outer surface of the transparent window 2 mounted to the case 1 to remove a bonded substance such as a raindrop from the transparent window 2. A means for controlling the unidimentional sensor 3 and the wiper 5 performs control so that the image detected by the sensor 3 becomes the image A at a the position immediately after the wiper 5 moves and passes. By this method, in case of rain, the unidimensional sensor 3 can detect the image outside the case through the transparent window held to the state immediately after a raindrop is removed by the wiper 5.
