Abstract

Optical reading system and methods are disclosed having multiple modes of operation, for example: omnidirectional and single-code picking; fixed and handheld reading; 1D and 2D code reading. In one configuration, an image-based system (2) obtains input data via an area sensor (12) such as a two dimensional CCD array with only a select portion of the data corresponding to a selected pattern of virtual scan lines (252-262) being stored and processed. The system may permit a user to implement different operating modes such as a first mode of reading optical codes in any location or orientation and a second mode of reading only an optical code oriented along a particular virtual scan line or group of lines, for example lines intersecting an aiming pattern (36, 236, 336) or a band (455) of parallel virtual scan lines. In another configuration, the data reader has multiple operating modes such as operable to switch between operating in a handheld mode selecting a first pattern of virtual scan lines to process and/or decode and a fixed mode selecting a second pattern of virtual scan lines to process and/or decode. Virtual scan patterns in either mode can change from frame to frame in a predetermined sequence, or in response to decodable data, to improve scanning performance.
