Abstract

An image capture apparatus includes a cover plate, a sensor, and an optical collimator disposed between the cover plate and the sensor and including a first, a second, and a third light shielding pattern layers that are overlapped with each other. The first, second, and third light shielding pattern layers have first, second, and third light-transmitting openings, respectively. A size of each third light-transmitting opening is larger than or equal to a size of each second light-transmitting opening, and the size of each second light-transmitting opening is larger than a size of each first light-transmitting opening. Alternatively, the size of each third light-transmitting opening is larger than the size of each second light-transmitting opening, and the size of each second light-transmitting opening is larger than or equal to the size of each first light-transmitting opening.
