Claim of US Patent No. 10,992,888

1. A method for identifying items on a conveyor belt with an Electronic Rolling Shutter (ERS) image capturing system, comprising:operating an imager in the ERS image capturing system in proximity to the conveyor belt, wherein the imager captures an image of an item on an object that travels on the conveyor belt;
operating a high-powered illuminator that illuminates multiple bands of illumination, wherein each band is illuminated and synchronized with an image exposure from the imager such that the multiple bands are illuminated individually and sequentially over a time period; and
as the object moves along the conveyor belt, performing the image exposure of a portion of the item with each band of illumination, wherein a composite of the image exposures results in a similar image of the item, wherein an image blur is reduced from a use of the high-powered illumination with sequenced multiple bands.
