Abstract
An endoscope includes a housing with a distal end insertable into a cavity; an image capture device at the distal end to obtain 3D images, and process them to form a video signal; and a folded substrate folded into a U-shape having first and second legs. The image capture device includes a detector and a lens system with right and left multi-band pass filters having right pass bands that are complements of left pass bands. The lens system receives the 3D images including right and left images. The detector faces the lens system to obtain the right and left images. A processing circuit faces the proximal end behind the detector to process signals from the detector. The folded substrate includes the detector at an outer side of the first leg facing the lens system and the processing circuit at an outer side of the second leg facing the proximal end.
