Abstract
An image capture system has an electronic rolling shutter (ERS) imager in area mode with high illumination to perform image acquisition (i.e. barcode reading) for fast moving items. Shearing distortion may occur but image blur is reduced and the image can be decoded. The ERS imager replaces global shutter imagers at a much lower cost and wider availability. The image capture system separates illumination into multiple bands in space and then synchronize the illumination bands with the exposure of the ERS imager in time. Much less illumination is required for the same image quality.
