Abstract
A single array of image sensors is used to obtain a plurality of different images at different levels of admitted exposure light from a common source level of exposure light. More particularly, first and second matrices of light-admitting elements are deployed in a single camera and disposed relative to focal lens light in front of corresponding first and second matrices of light-sensitive image sensors that are arrayed in a singular focal plane array in the camera and react equally to equal levels of color image information. The respective matrices of light-admitting elements transmit color image information from exposed focal lens light at different levels of brightness to their corresponding matrices of light-sensitive image sensors, wherein first and second images are acquired at the respective different levels of brightness from the respective matrices of the image sensors, and pixel data from the images combined to produce an HDR image.
