1. A dual-sensor video camera comprising:
- a panchromatic sensor;
a color filter array (CFA) sensor including a low-pass filter; and
a beam splitter;
wherein the beam splitter is configured to split a beam of light into a first beam directed to the panchromatic sensor and a second beam directed to the CFA sensor;
wherein the panchromatic sensor produces first image information from the first beam;
wherein the CFA sensor produces second image information from the second beam;
wherein the dual-sensor video camera further comprises one or more computational elements operable to produce an output image from the first image information and the second image information, wherein the output image includes luminance information from the first image information from the panchromatic sensor and chrominance information from the second image information from the CFA sensor.

Abstract
Various embodiments of a dual-sensor video camera are disclosed. The dual-sensor video camera includes a color filter array (CFA) sensor, which has a low-pass filter. The dual-sensor video camera also includes a panchromatic sensor. A beam splitter directs an incoming light beam to both sensors. An output image is produced based on image information from the two sensors. The output image includes luminance information based on the image information from the panchromatic sensor and chrominance information based on the image information from the CFA sensor.
