Based on the contro princip e of CCD vertica driving timing, a specia driving timing w ith a vert ica shift t iming inserted betw een tw o frames, w hich can transfer the re maining charge, is used for c earing the vertica b ooming of the highintensitypixe . T he driving timing is t ested on a CCD demo board of ICX205, and the t est ing resu t s show that the vertica b ooming is de e ted. This met hod has been app ied to int e igent traffic monit oring .
