Abstract
An image of a moving object, such as a postage indicium barcode on a mail piece, is captured with the object in motion (e.g., while being transported through a mailing machine). An array of CMOS picture elements is held in a reset condition. A signal asserted on control pin ends the reset condition and places the picture elements in an image capture condition. With the picture elements in a picture capture condition, a strobe light is actuated at a time when the barcode is predicted to be present at the picture element array. After the strobe light has been actuated, the signal on the control pin is de-asserted to initiate a read-out of the image data from the picture elements.
