Patent ID: 8866963

Claim:
A terminal comprising: an image sensor array having a plurality of pixels arranged over a two dimensional area; an imaging lens for use in focusing an image onto the image sensor array wherein the imaging lens in combination with the image sensor array define a field of view of the terminal; a light source bank for use in projecting light in a direction of the field of view; a hand held housing incorporating the image sensor array; wherein the terminal is configured to be operative in an operator selectable camera operating mode and an operator selectable flashlight operating mode; wherein the terminal is operative so that when a trigger signal is activated when operating in the camera operating mode, the terminal captures and processes a plurality of frames of image data, and energizes the light source bank during exposure periods for the plurality of frames, the terminal in the camera operating mode having a first average power consumption attributable to activity of the image sensor array and image data processing; and wherein the terminal in the flashlight operating mode responsively to activation of a trigger signal and during an active period captures a parameter determination frame and processes the parameter determination frame to determine an operating parameter determining an aspect of operation of the terminal in the flashlight operating mode, the terminal in the flashlight operating mode having a second average power consumption attributable to activity of the image sensor array and image data processing, the second average power consumption being lower than the first average power consumption, the terminal in the flashlight operating mode restricting operation of the image sensor array during an inactive period subsequent to the active period, the inactive period being longer than the active period.
