There is described in one embodiment an imaging apparatus having an image sensor, and a plurality of operating states. Operation of the imaging apparatus can be differentiated between the operating states. In one operating state, the imaging apparatus can capture a frame of image data having image data corresponding to a predetermined number of pixels of the image sensor. The operating states of the imaging apparatus can be user selectable. There is described in one embodiment an apparatus having an image sensor operative to capture a relatively smaller sized frame, wherein a characteristic of light directed by an illumination assembly for capture of a relatively larger sized frame is determined utilizing the relatively smaller sized frame.
