Title:
IMAGE CAPTURE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/203573
Kind Code:
A1
Abstract:
Detection of the incident angle of a ray of light passing through a grid board can be facilitated, thereby reducing the cost and power consumption of an image capture device. An image capture device 101 comprises: an image sensor 103 that transforms an optical image, captured by a plurality of pixels arranged in an array form on the image capture surface, to an image signal and that outputs the image signal; a modulator 102 that is placed on the light reception surface of the image sensor 103 and that modulates the intensity of light; and an image processing circuit 106 that performs an image processing of the image signal outputted from the image sensor 103. The modulator 102 comprises: a grid board 102a; a grid pattern 105 formed on the back surface of the grid board 102a approximate to the light reception surface of the image sensor 103; and a grid pattern 104 formed on the front surface opposed to that back surface. The grid patterns 104 and 105 each consist of a plurality of concentric circles. The modulator 102 uses the grid pattern 105 to intensity-modulate the light having passed through the grid pattern 104, and then outputs the light as intensity-modulated to the image sensor 103.
