Abstract
A filter control device of the present disclosure includes a filter controller that performs control to cause low-pass characteristics of an optical low-pass filter mounted in an imaging device to be changed in accordance with change in an image shooting range.
Claims13
A filter control device, comprising:
- a filter controller configured to change low-pass characteristics of an optical low-pass filter based on a change in an image shooting range,
- wherein the optical low-pass filter is mounted on an imaging device,
- wherein the optical low-pass filter includes a liquid crystal layer, a first electrode, a second electrode, a first birefringent plate, and a second birefringent plate,
- wherein the first birefringent plate and the second birefringent plate face each other, and
- wherein the liquid crystal layer, the first electrode, and the second electrode are between the first birefringent plate and the second birefringent plate.
