Abstract
Methods of calculating pixel values representative of a scene are disclosed herein. One embodiment of the method comprises focusing light representative of the scene onto a photosensor for a period of time using at least one exposure setting, wherein the photosensor has a plurality of pixels. Numeric values corresponding to the intensity of light received by each of the pixels during the period are generated. At least one exposure setting is changed and pixel values are generated by the photosensor based on the changed at least one exposure setting are calculated. The number of calculated pixel values that are greater than a first preselected value are then determined.
