发明名称 IMAGING DEVICE AND ENDOSCOPE DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide an imaging device capable of preventing flicker of an image which is obtained at focus control by performing the focus control on the basis of phase information from a phase sensor in an imaging optical system in which a focused subject distance is changed in association with change of a field angle, and to provide an endoscope device. <P>SOLUTION: The imaging device includes the imaging optical system having a movable lens 240 for simultaneously adjusting the field angle and the focused subject distance, an imaging element 260, a plurality of phase sensors, an acquisition unit (A/D converter 320) for acquiring the phase information from the plurality of phase sensors, a lens controller 360 for controlling the position of the movable lens 240, and a moving quantity calculation unit 350 for calculating a moving quantity of the movable lens 240 which is necessary to achieve a focused state of an image on the imaging element formed by light beams passing through the imaging optical system on the basis of a phase difference based on the phase information. The lens controller 360 controls the position of the movable lens 240 on the basis of the moving quantity calculated by the moving quantity calculation unit 350. <P>COPYRIGHT: (C)2013,JPO&INPIT
