APPARATUS FOR IMAGE ACQUISITION WITH SPEED COMPENSATION |
摘要 |
An image acquisition system includes a transport mechanism for transporting sheets of objects past a sensor. The sensor scans the objects and generates data streams which are scaled by a multiplier to compensate for the speed variation of the transport mechanism. At speeds much lower than a nominal speed, the scanning rate of the sensor is increased to generate several data streams for each scanned line, which are then combined in a single speed corrected signal stream for further processing.
