Abstract
Official abstract text for this publication.
An array of pixels of a solid-state imaging sensor having a rolling shutter is sequentially exposed to capture images from an illuminated target over successive frames for image capture by an imaging reader. The target is illuminated at a peak output power level for a fractional time period of a frame, and is not illuminated for at least a portion of a remaining time period of the frame for increased energy efficiency. Only a sub-array of the pixels is exposed during the fractional time period in which the target is being illuminated at the first output power level.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control system for an imaging reader having an illuminating light assembly for illuminating a target with illumination light, and a solid-state imaging sensor with a rolling shutter for sequentially exposing an array of pixels over an imaging field of view to capture images from the illuminated target over successive frames, the control system comprising: an illumination controller to control an output power level of the illumination light; and a m…
