Abstract
A camera system to capture a visual image comprising of a housing that allowing a beam of light representing the visual image to be captured to enter the housing. The camera system has a dichroic beam splitter placed in the path of the beam of light to split the beam of light into a two beams of light. The first beam of light is comprised of red light and blue light while the second beam is comprised of green light and near infrared light. The camera system has two filters that will filter the two beams of light. The first filter is comprised of an array of a first and second filter elements. The first filter element allows red light to pass through it while the second filter element allows blue light to pass through it. The second filter has an array of two filter elements as well. The first and second filter elements in the second filter will allow green and near infrared light to pass through it. The amount of filtered light for each of the spectral bands is roughly equal to each other. The filtered light from each filter will be intercepted by two image sensors that will measure the intensities of the red, blue, green and near infrared lights. Graphical displays and/or other ca…
