Abstract:
1. An infrared imaging apparatus comprising: an infrared light source with an emission distribution in an infrared region; an imaging lens; a Charge Coupled-Device (CCD) sensor in which light-sensitive elements with sensitivities in the infrared region and a visible region are arranged in a matrix-like fashion; and a color filter for each color, with each color filter coupled with a corresponding light-sensitive element of the light-sensitive elements; each color filter transmitting visible light in a specific wavelength region and infrared light in a specific wavelength regions; an infrared transmission filter for allowing infrared light to pass through while removing visible light; an imaging signal generation circuit for generating an imaging signal based on the infrared light incident to the image sensor, with the imaging signal generation circuit coloring the image signal based on differences in peak values of imaging signal output values provided by each color filter; a digital conversion processor for converting the imaging signal into a digital signal; and a memory for temporarily storing the digital signal converted by the digital conversion processor.
