Abstract: A multi-channel glare-suppression device of a digital image system first acquires a spatial image, and at least one first lens set then collects light from the spatial image and generates an optical image. The optical image then passes through or is reflected by an optical modulation module to generate a modulated image. At least one second lens set further scales the modulated image and focuses the modulated image to generate a scaled image on a photo-sensing module for the photo-sensing module to convert the scaled image into an image signal. A processing module senses the photo-sensing module. When detecting a current higher than a threshold generated in a region of the photo-sensing module, the processing module then generates the control signal to modulate a region of the modulated image so as to attenuate the glare in the region of the modulated image.
