Abstract
A camera, comprising at least one photodetector, and a light directing device. The light directing device separates light of a wavelength from about 360 nm to about 420 nm to form an NUV component and directs the NUV component to the at least one photodetector whereby the photodetector receives the NUV component and forms a red correction signal.
Claims14
A camera, comprising:
- at least one photodetector;
- means for separating light of a wavelength from about 360 nm to about 420 nm to form an NUV component and directing the NUV component to the at least one photodetector whereby the photodetector receives the NUV component and forms a red correction signal.
A camera, comprising:
- two photodetectors;
- a prism receiving light indicative of an image and for splitting the light into a first light beam and a second light beam, the first light beam being a first color and being directed to one of the photodetectors;
- a filter mask having a predetermined pattern formed by one or more filtering regions of a second color, one or more filtering regions of a third color, and one or more filtering regions for passing the NUV component, the second filter mask receiving the second light beam and transmitting light of the first and second colors, and the NUV component to the other one of the photodetectors.
