Abstract
Image processing for scanning devices based on laser aimer position, wherein a first frame and a second frame of image data related to an object associated with a barcode are captured using a scanning device. A difference between first pixel data for a first grouping of pixels associated with the first frame and second pixel data for a second grouping of pixels associated with the second frame is computed. Additionally, a location of a laser aimer pattern in the first frame or the second frame is determined based on a comparison between respective differences between the first pixel data for the first grouping of pixels and the second pixel data for the second grouping of pixels, where the laser aimer pattern is created by the scanning device.
