Abstract

Official abstract text for this publication.

An image sensing system includes: a light emitting device; a pixel configured to capture an optical signal and to convert the optical signal into an analog image signal; an analog circuit configured to selectively filter the analog image signal; an analog-to-digital converting circuit configured to convert the analog image signal to a digital image signal; a digital circuit configured to receive the digital image signal and to switch the light emitting device on and off; wherein the digital image signal includes a dark image frame if the optical signal is captured when the light emitting device is off; wherein the digital image signal includes an effective image frame if the optical signal is captured when the light emitting device is on and the analog circuit is configured to filter the analog image signal; and wherein the digital image signal includes a punctured image frame if the optical signal is captured when the light emitting device is on and the analog circuit is not configured to filter the analog image signal.

First claim

Opening claim text (preview).

What is claimed is: 1. A capsule-type endoscope for use in a human body, wherein the capsule-type endoscope comprises: a light-emitting device configured to be: turned on during capture of an effective image frame and a punctured image frame; and turned off to create an aphotic state during capture of a dark image frame; a plurality of pixels configured to capture light and to convert the light into an analog image signal; an analog circuit configured to filter the analog…
