INDICIA READING TERMINAL PROCESSING PLURALITY OF FRAMES OF IMAGE DATA RESPONSIVELY TO TRIGGER SIGNAL ACTIVATION

摘要

There is described a decodable indicia reading terminal which in one embodiment can capture and process a certain (e.g., a first) and a subsequent (e.g., a second) frame of image data, wherein the certain and the subsequent frames have different imaging attributes. In one embodiment the attributes between certain and subsequent frames are differentiated in that the certain frame represents light incident on pixels of a first image senso r and the subsequent frame of image data represents light incident on pixels of a second image sensor spaced apart from the first image sensor. Additionally, or in the alternative, the attributes between certain and subsequent frames can be differentiated in that the first frame represen ts light incident on an image sensor under a first illumination profile and the subsequent frame represents light incident on pixels of an image sensor under a second illumination profile. I n one embodiment imaging attributes of a frame subject to decoding are maintained constant for each frame subject to processing during a time that a trigger signal remains active. In one embodiment the certain and subsequent frames can be processed to yield parti al decoding results and the partial decoding results can be combined to form a complete decoding result.
