Development of a high-resolution surveillance camera with 520 TV lines

We have developed digital signal processing algorithms one of which realizes high-quality image with 520TV lines of horizontal resolution using a single-chip color 410k pixels- CCD and the other improves vertical resolution in an electronic zoom. We have also developed a single-chip LSI realizing these algorithms in real-time and a high- resolution surveillance camera with 520TV lines. These algorithms consist of three technologies as follows: (1) Chroma adaptive horizontal aperture compensation area by area (2) Edge adaptive color separation and new optical LPF with high MTF (3) Motion adaptive electronic zoom.
