Title:
INFRARED PIXEL SENSOR AND INFRARED SIGNAL CORRECTION
Document Type and Number:
WIPO Patent Application WO1999050682
Kind Code:
A3
Abstract:
An infrared pixel sensor comprising a pixel and a composite infrared pass filter (item marked: IR (R+B)) comprising a plurality of filters, wherein each filter belonging to the plurality of filters is substantially transparent to infrared radiation and has a visible pass spectrum so that the composite infrared pass filter is substantially opaque to visible light. Signals from infrared pixel sensors are subtracted from color pixel sensors (items marked: R, G, B) to correct for infrared radiation in the image signal without the need for an infrared blocking filter.
