Abstract
An image pickup apparatus includes a lens, an image sensor, an optical filter, and a driving device. The lens focuses light beams from at least one subject to form an optical image, and the image sensor receives the optical image and converts the optical image into at least one electric signal. The optical filter includes a first plate and a second plate, the first plate is disposed between the lens and the image sensor, and the second plate is disposed between the first plate and the image sensor. The driving device moves the second plate. The second plate has substantially the same index of refraction as the first plate, and a thickness of the second plate is continuously decreased or increased across the second plate.
