Abstract:
1. A digital security camera apparatus comprising: a light source for generating light at a plurality of discrete wavelength bands for illuminating a target; a monochrome digital camera; a switching circuit for activating said light source for alternatively generating light at each of said plurality of discrete wavelength bands sequentially so the target is illuminated by light at only one of the plurality of discrete wavelength bands during a predetermined period of time and for controlling said monochrome digital camera to sequentially capture images of said target illuminated by light individually at each of said plurality of discrete wavelength bands; a storage device for storing said captured images; and a processor for retrieving said captured images from said storage device, for individually assigning each of said captured images to one of a plurality of color channels, for colorizing each of said captured images with one of a plurality of monochromatic colors associated with a respective assigned color channel, and for combining said colorized captured images to form a pseudo-color composite image, wherein a number of color channels in the plurality of color channels and a number of monochromatic colors in the plurality of monochromatic colors is equal to a number of discrete wavelength bands in the plurality of discrete wavelength bands.
