TERMINAL HAVING PLURALITY OF OPERATING MODES
First Claim
1. 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; and
wherein the terminal is further operative so that when a trigger signal is activated when operating in the flashlight operating mode, the terminal energizes the light source bank and restricts operation of the image sensor array for a duration of the flashlight operating mode.

Abstract
There is set forth herein a terminal having an image sensor array and a plurality of operator selectable operating modes. The image sensor array can have an associated light source bank. The operator selectable operating modes can include at least one camera operating mode and at least one flashlight operating mode. In the at least one camera operating mode the image sensor array and light source bank can be controlled for optimization of frame capture. In the at least one flashlight operating mode the image sensor array and the light source bank can be controlled for optimizing illumination of an operators viewing area with reduced average power consumption.

13. A terminal comprising:
-
an image sensor array having a plurality of pixels arranged over a two dimensional area; an imaging lens for 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; a CPU configured to execute system level software, the system level software including a basic input/output system (BIOS) and an operating system; 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 in the camera operating mode executes a first software program, the terminal in accordance with the first software program subsequent to activation of a trigger signal energizing the light source bank and controlling the image sensor array so that the terminal has a first average power consumption attributable to activation of the image sensor array and processing of image data; wherein the terminal in the flashlight operating mode executes a second software program, the terminal in accordance with the second software program energizing the light source bank and controlling the image sensor array so that the terminal in the flashlight operating mode has a second average power consumption attributable to the activation of the image sensor array and processing of image data, the second average power consumption being less than the first average power consumption; wherein said first software program is executed as an application controlled by the operating system; and wherein said second software program is provided as a part of the system level software. - View Dependent Claims (14, 15, 16, 17, 18, 19)
