Paper Abstract

How CCD camera causes vertical blooming was investigated. The technique based on vertical driving timing, which can clear vertical blooming up the high-intensity pixels, was presented. The saturated charge of photo diode, which is produced by high-intensity-pixel during the exposure time of a line, enters the vertical shift register. On the control of CCD vertical driving timing, all pixels of the same column add the saturation charge, and then the image has vertical blooming. The vertical blooming up the high-intensity-pixel is produced by the saturation charge of the last frame. Depended on the control method of charge transfer, a special driving timing, which can transfer the remaining charge, is used for clearing the vertical blooming up the high-intensity-pixel. The driving timing is tested on a CCD demo board of ICX205, and the testing showed that the vertical blooming up the high-intensity-pixel is deleted. This method has been applied to intelligent traffic monitoring.
