Title: IMAGE SENSOR METHOD AND APPARATUS EQUIPPED WITH MULTIPLE CONTIGUOUS INFRARED FILTER ELEMENTS
Abstract:
An image sensor apparatus and method are provided with multiple contiguous infrared (IR) filter elements. Included is an image sensor comprising a two-dimensional array of pixel elements that generate output signals as pixel data for representing an image of a scene. Further included is a filter array comprising a two-dimensional array of filter elements coupled to the two-dimensional array of pixel elements to receive light input from the scene. The filter array includes a plurality of blocks of filter elements each including a first subset of filter elements configured to transmit spectral energy in one or more colors of a visible spectrum of the light. Each pair of adjacent filter elements of the first subset are configured to transmit spectral energy in different colors of the visible spectrum of the light. Further, each block of filter elements also includes a second subset of filter elements configured to transmit spectral energy in an infrared (IR) spectrum of the light. The second subset of filter elements includes at least two (2) IR filter elements that are contiguous.
