Object detecting system
First Claim
Patent Images
1. An object detecting system comprising:
- a light emitting mechanism to emit light toward an object occupying a vehicle seat;
a control mechanism to control the light emitting mechanism;
a photographing mechanism including an optical lens and a distance measuring image chip, wherein light emitted from the light emitting mechanism and reflected by the object is incident on the distance measuring image chip through the optical lens and is focused into a focusing area of the distance measuring image chip; and
a processing mechanism to derive information about the object from the focused image on the distance measuring image chip of the photographing mechanism;
wherein the control mechanism changes the light emitting mode of the light emitting mechanism based on information about the quantity of incident light derived by the processing mechanism such that the quantity of incident light on the distance measuring image chip is equalized to respective portions of the focusing area.

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.
