Patent Images
1. An automotive CCD camera comprising:
- a UV filter receiving light corresponding to lane markers and filtering UV light;
a condenser condensing the UV light filtered through the UV filter;
a light disperser dispersing the UV light condensed by the condenser to output at least one light through at least two different paths;
a CCD cell assembly converting the light input through the at least two different by the light disperser into image signals; and
an adder adding the image signals output by the CCD cell assembly and outputting image signals in which yellow lane markers can be extracted.

Abstract
An automotive CCD camera includes a UV filter receiving light corresponding to lane images and filtering through ultraviolet light, a condenser condensing the UV light filtered through the UV filter and transmitting the light, and a light disperser dispersing the light transmitted by the condenser to output the light through at least two different paths. A CCD cell assembly receives the light dispersed by the light disperser, photographs the same and outputs light signals. An adder adds the light signals output by the CCD cell assembly and outputs image signals in which yellow lane markers can be extracted.

a first CCD cell receiving the light condensed by the condenser through a first path, photographing the light and outputting first image signals to the adder;
a second CCD cell receiving the light condensed by the condenser through a second path, photographing the light and outputting second image signals to the adder; and
a third CCD cell receiving the light condensed by the condenser through a third path, photographing the light and outputting third image signals to the adder.
