Abstract
A device 12 acquires substantially centered images of moving items. A strobe (36) illuminates an item (16) while a camera 28 having a view (29) with a view center (39) acquires an image of that item (16). A position sensor (38) generates an indication signal that indicates when an item (16) is substantially a predetermined distance (D) from the view (29), and an image-data memory (31) stores data representing each image. A processor (24) executes a program for waiting a delay from each indication signal and then instructing the strobe (36) to fire, the camera (28) to acquire an image, and the image-data memory (31) to store the image. The processor (24) then determines an offset value representing the offset of the image from the view center (39), updates an average offset value using the offset value, and updates the delay using the updated average offset value. A program memory (20) stores the program, and a working memory (20) stores the offset value, the delay, and the average offset value.
