Systems and methods for simultaneous capture of two or more sets of light images

摘要

Described herein are systems and methods that provide effective way for simultaneous capture of infrared and non-infrared images from a single camera. In embodiments, a filter comprises at least two types of filters elements: (1) an infrared filter type that allows infrared light to pass through the filter element; and (2) at least one non-infrared filter type that allows light in a visible spectrum range or ranges to pass through the filter element. In embodiments, the filter elements form a pattern of the infrared filter elements and the non-infrared filter elements and is positioned relative to a camera's array of sensor cells to form a correspondence between sensor cells and filter elements. In embodiments, signals captured at the camera's sensor cells may be divided to form an infrared image and a visible light image that were captured simultaneous, which images may be used to determine depth information.
