Definitions
- Imaging system for capturing color images with a black and white camera
- the present invention relates to an imaging system, and more particularly to an imaging system for capturing color images using a black and white camera. Background technique:
- Ordinary color camera imaging is a method of using Bayer Fierter Pattern plus filter.
- the pixel value is calculated by using the adjacent pixel value and its own pixel value to calculate the R, G, and B values of each pixel.
- the color of the adjacent pixels of the color camera is easy to overflow, causing color distortion and low color saturation; and the filter must be used, which is not sensitive to light; the flexibility is not strong and the cost is high.
- an imaging system for capturing a color image with a black and white camera which uses a black and white camera, and is independently controlled by the external light
- the red, green, and blue light are separately controllable and the object to be photographed
- three images of red, green and blue light are respectively turned on, and the grayscale images respectively illuminated by the red, green and blue light sources are combined on the red, green and blue channels corresponding to the color image.
- a high-resolution color image is obtained.
- the system consists of a black and white camera, a red light source group, a green light source group, and a blue light source group. Different color light sources are separately opened, three kinds of grayscale images are respectively captured, and the color images are synthesized by a software method.
- the system is applied to an optical inspection system.
- the resolution is three times that of the Bayer Filter tern color camera, and there is no problem that the Bayer Filter tern color camera's photo-electronic overflow of adjacent pixels makes the image color vivid, and Improves image saturation without the need for filters, improving imaging for light Sensitivity; Because the power is used separately, the brightness of the light source can be adjusted separately. On the gray palette, the brightness of the image is adjusted to uniform brightness, and the synthesized image can be white balanced, and the synthesized color image is more realistic.
- the method of the present invention has better effects than the 3CCD camera, but the cost is only 1/6.
- the figure is a schematic diagram of the principle of the present invention.
- an imaging system for capturing a color image with a black and white camera, using a black and white camera, independent of external light, red, green, and blue light separately controllable and the object being photographed stationary relative to the camera , respectively, three images of red, green and blue light are respectively turned on, and the grayscale images respectively illuminated by the red, green and blue light sources are combined on the red, green and blue channels corresponding to the color image, and finally the high resolution is obtained.
- the system consists of a black and white camera, a red light source group, a green light source group, and a blue light source group. Different color light sources are separately opened, and three grayscale images are respectively captured, and then the color images are synthesized by a software method. The system is applied to an optical inspection system.

Abstract
L'invention concerne un système d'imagerie. Dans le système, la caméra noir et blanc prend des images, trois fois, avec une couleur rouge, une couleur verte et une couleur bleue. La caméra compose les images grises éclairées par la DEL rouge, la DEL verte et la DEL bleue en images couleur en fonction du canal rouge, du canal vert et du canal bleu. Ensuite, une image couleur haute résolution peut être formée. A l'aide de la présente invention, la résolution peut être 3 fois celle obtenue à l'aide de la caméra couleur à modèle de filtre Bayer. Le problème de débordement de photoélectrons des pixels voisins ne peut pas se produire. L'invention permet d'obtenir l'image en couleur naturelle et elle améliore la saturation de l'image. Le filtre n'est pas nécessaire. Il améliore la sensibilité de la lumière au cours de la formation d'images. La lampe à DEL peut être réglée séparément du fait de la lampe individuelle. Elle permet à l'image d'atteindre l'équilibre des blancs. Le coût de la présente invention est égal à 1/6 de la caméra 3CCD.
