Claim Text:
1. A system for high dynamic range imaging, the system comprising: an image sensor comprising an array of light-sensing elements, wherein the image sensor detects an image of a scene and provides pixel values that represent light intensities impinging on respective ones of the light-sensing elements; a mask comprising a plurality of light-transmitting cells that are each configured to attenuate the intensity of light transmitted through the mask onto the light-sensing elements such that the scene is exposed to the light-sensing elements in a spatially varying manner with each of the light-sensing elements having a corresponding exposure value indicative of the transparency of one or more light-transmitting cells through which light impinging on the light-sensing element passes, wherein the mask is interposed between the scene and the array of light-sensing elements of the image sensor; and an image processor coupled to the image sensor for receiving the pixel values provided thereby, wherein the image processor determines high dynamic range image data using at least the pixel values as function of the exposure values.
