CONTROL DEVICE, IMAGE PICKUP DEVICE, AND METHOD FOR CONTROLLING LIQUID CRYSTAL LOW-PASS FILTER

摘要

This control device is provided with a control unit that performs a control such that a liquid crystal layer of a liquid crystal low-pass filter is in one polarization state among a first polarization state, a second polarization state, and an intermediate polarization state that is a polarization state between the first polarization state and the second polarization state. In the cases of outputting a plurality of image data from an image pickup element, the control unit performs the control such that the polarization state of the liquid crystal layer is in the first polarization state or the second polarization state at the time of outputting first image data, and performs the control such that the polarization state of the liquid crystal layer is in the intermediate polarization state at the time of outputting second image data or second image data and the subsequent data.
