Abstract
In one embodiment, a method for sensing an image of a scene includes receiving incident light at a image sensing device including an array of at least two regions of pixel elements, providing one or more control parameters where each of the control parameters modifies the sensitivity of the pixel elements, generating control signals for the one or more control parameter for each region of pixel elements where the sensitivity of the pixel elements is varied on a region by region basis. In another embodiment, method for sensing an image of a scene includes generating control signals for controlling two or more control parameters for controlling the pixel elements of an entire array to provide continuous fine grain control of the sensitivity of the pixel elements.
