Abstract:
1. An image pickup apparatus, comprising: a polarization removing element layer including a plurality of polarization removing elements, each of the plurality of polarization removing elements being configured to polarize an incident light to thereby obtain light having a polarization axis in a predetermined direction and to transmit the polarized light, the polarization axis of one polarization removing element intersecting with the polarization axis of another polarization removing element; a polarizer layer provided in front of the polarization removing element layer, the polarizer layer being configured to twist polarization axes of light having a plurality of polarization axes by predetermined angles, respectively, and to transmit the light; an inclination detecting device configured to detect inclination of the incident light to an optical axis; a controller configured to control and drive the polarizer layer such that the polarizer layer twists the polarization axis of light depending on the inclination detected by the inclination detecting device and transmits the light; and an image pickup device configured to detect the light passing through the polarization removing element layer.
