Scanning method with two exposure steps

摘要

A scanning method with two exposure steps. A scanning system is driven with a motor. While the motor is stopped after rotating a predetermined distance, the scanning process is started. In the first scanning step, an odd (even) number of pixel video data is obtained. The odd (even) number of pixel video data is compensated as required. In a second scanning step, an even (odd) number of pixel video data is compensated as required. The video data is then output.
