IMAGE PICKUP DEVICE AND PORTABLE TERMINAL DEVICE

摘要

An image pickup device (1) is provided with an image pickup optical system (2) including an optical filter (6) for limiting transmission of a light having a prescribed wavelength, and an image pickup element (3) for performing image pickup by receiving an image pickup light from the image pickup optical system (2). The optical filter is curbed so that an angle of light entering a light entry area of the optical filter (6) is smaller than that in a case where the optical filter is flat.
