Reading apparatus having partial frame operating mode
First Claim
1. A reading apparatus for reading decodable indicia disposed within an area, the reading apparatus comprising:
- an imaging assembly comprising a two dimensional image sensor having a plurality of pixels, the plurality of pixels formed in a plurality of rows of pixels, the imaging assembly having optics focusing an image onto the two dimensional image sensor;
wherein the reading apparatus is adapted to enable an operator to select between a first user selected operating state and an alternative user selected operating state, the reading apparatus being adapted for attempting to decode decodable indicia represented in a frame of image data captured using the two dimensional image sensor whether the first user selected operating state or the alternative user selected operating state is active;
wherein the reading apparatus is adapted to clock out image data corresponding to pixels of the two dimensional image sensor whether the first user selected operating state or the alternative user selected operating state is active;
wherein with the first user selected operating state active, the reading apparatus is adapted for capturing a partial frame of image data and for attempting to decode decodable indicia represented in the partial frame of image data, the reading apparatus not being adapted for capturing a full frame of image data with the first user selected operating state active;
wherein with the alternative user selected operating state active, the reading apparatus is adapted for capturing a full frame of image data and attempting to decode decodable indicia in the full frame of image data.

Abstract
A method for decoding a decodable symbol using an optical reader having a 2D image sensor that is configured to operate in a partial frame capture operating mode. In a partial frame operating mode, the reader clocks out and captures at least one partial frame of image data having image data corresponding to less than all of the pixels of an image sensor pixel array. In one embodiment, the reader operating in a partial frame operating mode captures image data corresponding to a linear pattern of pixels of the image sensor, reads the image data, and attempts to decode for a decodable bar code symbol which may be represented in the image data.
