Abstract
An image detection system for a car arranged such that only when the drive angle of a wiper of the car resides within a predetermined image pickup angle range or a predetermined image pickup angle range corrected according to the pan angle of a TV camera unit, a change-over switch is controlled to change over to the side of an image storage from which static image data are provided as outputs. Alternatively, it can be arranged such that a masking range the wiper crosses in all of the scanning lines, of an image in front of the wiper, perpendicular to the moving direction of the wiper is determined from a drive angle of the wiper and only the image of the scanning lines for the wiper is masked and substituted by blank data or static update data.
