Abstract
This invention relates to an imaging system employing black-and-white camera to photograph colorful images. Wherein, with a monochrome camera, shooting the target with red light, green light and blue light respectively; composing the gray-level images irradiated by opposite lights to obtain the color image with high resolution as three times to the Bayer Filter Pattern color camera without near photoelectron overflow. This invention obtains vivid image, improves image saturation level and sensitivity to light, and needs cost just as one sixth of the 3CCD camera.
Description
Technical field:
The present invention relates to a kind of imaging system, particularly utilize the imaging system of black and white camera color image shot.
Background technology:
The common color camera imaging is to adopt Bayer Filter Pattern to add the mode of optical filter, and pixel value carries out R, G, the B value that color interpolation algorithm calculates each pixel with adjacent pixel values and self pixel value.Adopt the color camera neighbor pixel photoelectron of this kind mode easily to overflow, cause the cross-color phenomenon, the color degree of saturation is on the low side; And must adopt optical filter, not strong to the sensitivity of light; Dirigibility is not strong, the cost height.
Summary of the invention:
The purpose of this invention is to provide a kind of color true to nature, need not optical filter, the imaging system with employing black-and-white camera to photograph colorful images low to luminous sensitivity height, cost.
In order to achieve the above object, the present invention is by the following technical solutions: with the imaging system of employing black-and-white camera to photograph colorful images, it adopts the black and white camera, not influenced by exterior light, ruddiness, the separately controlled and subject of green glow and blue light is with respect under the static state of camera, open ruddiness respectively, three photographic images of green glow and blue light, ruddiness, the redness of the gray level image combined color image correspondence under green glow and blue light source shine respectively, on green and the blue channel, obtain the coloured image of high-res at last, system is by the black and white camera, the red light source group, green light source group and blue-light source group are formed.Open different colored light sources respectively, photograph three kinds of gray level images respectively, use the software approach combined color image again.This system applies is in the optical detection system.
Adopt the invention of above technical scheme, its resolution is three times of Bayer Filter Pattern color camera, the problem that does not exist Bayer Filter Pattern color camera neighbor pixel photoelectron to overflow, make color of image true to nature, and improved the degree of saturation of image, need not to adopt optical filter, improved the sensitivity of imaging light; Because of adopting independent power supply, light-source brightness can be adjusted separately, on the gray tone colour table, brightness of image is transferred to unified brightness, just can make synthetic image reach white balance, and the coloured image that is synthesized has truer.Mode of the present invention is than the better effect of 3CCD camera, but cost have only its 1/6.
Description of drawings:
Fig. 1 is a principle schematic of the present invention.
Embodiment:
Below the present invention is further described: with the imaging system of employing black-and-white camera to photograph colorful images, adopt the black and white camera, not influenced by exterior light, ruddiness, the separately controlled and subject of green glow and blue light is with respect under the static state of camera, open ruddiness respectively, three photographic images of green glow and blue light, ruddiness, the redness of the gray level image combined color image correspondence under green glow and blue light source shine respectively, on green and the blue channel, obtain the coloured image of high-res at last, system is by the black and white camera, the red light source group, green light source group and blue-light source group are formed.Open different colored light sources respectively, photograph three kinds of gray level images respectively, use the software approach combined color image again.This system applies is in the optical detection system.
Claims (3)
