Abstract
The automatic tracking of the doubtful movement is proposed to support the security agent. The automatic tracking function is realized by the motion vector detection and the electronic zoom. Additionally, the luminance flicker and the color flicker reduction algorithms, the long-time exposure function, and the digital noise reduction(DNR)for CCD raw signals are proposed. As realizing these digital image processing technologies, we have developed a new LSI for the high-grade surveillance camera system. This LSI contains processing circuits not only for these new functions but for all CCD color cameras with the exception of a V-drive IC for driving the CCD and a pre-process IC(CDS/AGC/ADC-IC). This LSI realizes the small-sized surveillance camera with superior functions and high perfornance.
