Bar code reading device having plurality of operating states
First Claim
Patent Images
1. A bar code reading device for reading a bar code symbol disposed within an area, said bar code reading device comprising:
- an imaging assembly comprising a two dimensional image sensor having a plurality of pixels, said plurality of pixels formed in a plurality of rows of pixels, said imaging assembly having optics focusing an image onto said image sensor, wherein there is a maximum number of pixels of said image sensor from which image data can be read out from when said bar code reading device is operated to read said bar code symbol; and
a user interface enabling an operator to select between a first and a second alternative operating state, said bar code reading device being configured to attempt to decode a bar code symbol represented in captured image data captured by said bar code reading device whether said first operating state or said alternative operating state is active;
wherein said bar code reading device, when said first operating state is active is restricted from reading out image data corresponding to said maximum number of pixels of said image sensor;
wherein said bar code reading device, when said alternative operating state is active is capable of reading out said maximum number of pixels of said image sensor.

Abstract
There is described a bar code reading device having an image sensor, a first operating state and an alternative operating state. In the first operating state the bar code reading device can be restricted from reading out image data corresponding to a maximum number of pixels of the image sensor. In the alternative operating state, the bar code reading device can be capable of reading out a maximum number of pixels of the image sensor. The bar code reading device can attempt to decode a bar code symbol represented in captured image data whether the first operating state or the alternative operating state is active.
