Business methods using an optical reader having partial frame operating mode
First Claim
1. A method of conducting a business transaction involving information recorded in an encoded indicium, the method comprising the steps of:
- operating an optical reader having a 2D image sensor;
capturing with the 2D image sensor a partial frame of image data from an encoded indicium; and
processing image data of said partial frame of image data to extract information encoded by the encoded indicium whereby the purposes of the business transaction are advanced.

Abstract
A method of conducting a business transaction involving information recorded in an encoded indicium using an optical reader having a 2D image sensor that is configured to operate in a partial frame capture 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, attempts to decode for a decodable 1D symbol which may be represented in the image data, and captures a full frame of image data if the image data reading reveals a 2D symbol is likely to be present in a full field of view of the 2D image sensor.

11. A method of conducting a business transaction involving information recorded in an encoded indicium, said method comprising the steps of:
-
(a) operating an optical reader having a 2D image sensor;
(b) in a partial frame operating mode, capturing a partial frame of image data, the partial from of image data including at least a portion of the encoded indicium;
(c) attempting to extract information encoded by the encoded indicium from the captured partial frame of image data; and
(d) if in step (c) the reader fails to extract information encoded by the encoded indicium, switching operation of the reader to a full frame capture mode. - View Dependent Claims (12, 13, 14, 15)

22. An apparatus for conducting a business transaction involving information recorded in an encoded indicium, the apparatus comprising:
-
an optical reader having a 2D image sensor configured to image an encoded indicium;
a control module configured to operate the 2D image sensor to capture a partial frame of image data from the encoded indicium; and
a processing module configured to process the partial frame of image data to extract therefrom information encoded by the encoded indicium, whereby the purposes of the business transaction are advanced. - View Dependent Claims (23, 24, 25, 26)
