Title
Dual-band multi-aperture enhanced redox imaging of colonic adenomas for endoscopes with a high-performance CMOS imager.
Abstract
Dual-band multi-aperture imaging of colonic adenomas based on the redox condition of mucosal cells for next-generation endoscopes is proposed. A low-noise and high-dynamic-range CMOS imager with the folding integration and the cyclic ADC is utilized in the single-imager multi-aperture camera system with 475-nm and 530-nm band-pass filters. A redox image is calculated from four kinds of images, 475-nm and 530-nm fluorescence images for 365-nm and 405-nm excitation lights. Dark current and random noise are reduced with a selective averaging method. The contrast of the redox image has been successfully enhanced.
