A real-time switchable random access color or color combination LED or laser diode illumination multispectral video imaging system comprising (switchable illumination means) a black and white photo-imaging array sensor, means for acquiring an image of an object, signal processing means for creating a color or false color video image of the object, control means for control of the spectral images combination ways, intensity, image overlay and other image processing means and a method for creating a real-time random access video image, where the object is illuminated by a desired number of LEDs whose output is combined to give a uniform, spectrally colored beam, and means for processing the obtained image. Preferably a color image is produced by electronically memorizing and combining three sequential images, each of them illuminated with one of the corresponding red, green and blue LED lights. One or more LED's are used, the light output being combined into a uniformly spectrally colored beam for object illumination. The system comprises also means for excitation light source for induced fluorescence purposes, and ability to detect and present chemiluminescence or phosphorescence or any other light emission induced effect in the observed object. |
