PROBLEM TO BE SOLVED: To provide an electronic endoscope apparatus including an imaging device, capable of automatically detecting the tilt of the imaging device relative to an optical axis of an objective optical system.SOLUTION: A solid-state imaging device 120 includes: a plurality of pixels 122 each including a light-receiving part 121 with which a plurality of light-receiving elements are formed, the plurality of light-receiving elements generating pixel signals and a tilt detection element for detecting the tilt of a light flux incident to a light-receiving plane. The tilt detection element includes: a swing detection part 124 (an X-axis direction tilt detection element group) for detecting the tilt of the light flux, in an X-axis direction that is parallel with the light-receiving plane, relative to a perpendicular of the light-receiving plane and a tilt detection part 126 (a Y-axis direction tilt detection element group) for detecting the tilt of the light flux, in a Y-axis direction that is parallel with the light-receiving plane and vertical to the X-axis direction, relative to the perpendicular of the light-receiving plane.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2016,JPO&INPIT【課題】対物光学系の光軸に対する撮像素子の傾きを自動的に検知可能にした、撮像素子を備えた電子内視鏡装置を提供する。【解決手段】固体撮像素子120は、複数の受光素子が形成された受光部121を有し、複数の受光素子が、画素信号を生成する複数の画素122と、受光面に入射する光束の傾きを検知するための傾き検知素子と、を含む。傾き検知素子が、受光面の垂線に対する、受光面と平行なX軸方向への、光束の傾きを検知するスイング検知部124(X軸方向傾き検知素子と群)、受光面の垂線に対する、受光面と平行且つX軸方向と垂直なY軸方向への、光束の傾きを検知するチルト検知部126(Y軸方向傾き検知素子群)と、を含む。【選択図】図4
