ABSTRACT:
An object detecting system, which is installed in a vehicle, uses a camera comprising an optical lens, a distance measuring image chip, and an illumination device to detect information about an object occupying a vehicle seat. The light emitting mode of a first illuminant and a second illuminant of the illumination device is controlled in such a manner that the quantity of incident light onto the distance measuring image chip is equalized to respective portions in the focusing area.
