Abstract

A camera system is provided to increase a baseline. The camera system includes a single lens, and an image sensor includes at least one pixel array, each of the at least one pixel array including a plurality of pixels in a two-dimensional arrangement and a single micro lens disposed on the plurality of pixels to be shared. Light shielding layers formed with Offset Pixel Apertures (OPAs) are disposed on at least two pixels of the plurality of pixels, and the OPAs are formed on the light shielding layers to maximize a spaced distance between the OPAs.

Description

Technical field [0001] The following description relates to a camera system that uses disparity (Disparity) to calculate the depth of a subject, and specifically relates to a camera system that structurally increases the range of the calculated depth and increases the baseline. Background technique [0002] The method of calculating the depth of the subject represented by the distance between the camera system (to be precise, the image sensor included in the camera system) and the subject is to use the image obtained through the multiple offset apertures of the camera system The way the blur (blur) changes between and the way to use parallax. [0003] In more detail, in the conventional parallax method, after a stereo camera system is composed of two lenses and an image sensor, the optical signals flowing in through the two lenses are processed to obtain two images with parallax, based on the two images The parallax between the two is calculated by the formula to calculate the dep...
