PROBLEM TO BE SOLVED: To provide an endoscope which allows light receiving pixels to be provided as many as possible without deteriorating a function of correcting a noise.SOLUTION: An endoscope comprises: a light receiving element chip that mounts a first light receiving element and a signal processing chip that mounts a second light receiving element, a noise correction circuit, and a signal processing circuit. The signal processing circuit corrects an output of the noise correction circuit by using a difference between an output of the first light receiving element and an output of the second light receiving element.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2019,JPO&INPIT【課題】ノイズを補正する機能を損なうことなく、受光画素をできる限り多く設けることができる内視鏡を提供する。【解決手段】本発明に係る内視鏡は、第1受光素子を実装した受光素子チップを備えるとともに、第2受光素子とノイズ補正回路と信号処理回路を実装した信号処理チップを備え、前記信号処理回路は、前記第1受光素子の出力と前記第2受光素子の出力との間の差分を用いて、前記ノイズ補正回路の出力を補正する。【選択図】図4
