A new adaptive frame rate up conversion algorithm and its ASIC design for consumer television are presented. The algorithm of adaptive frame rate up conversion with field frame detection for high quality video format conversion is applied in the chip, which can convert PAL 50 Hz interlaced picture into 50～65 Hz progressive picture, or NTSC 60 Hz interlaced picture into 60～70 Hz progressive picture. This algorithm is efficient and can be easily used in hardware implementation. Other video processing algorithms are also integrated in this chip, including Black/White Level Expansion, picture edge based 2 D filter, chroma transient improvement (CTI), color space convert (CSC), and gamma correction. The 0.35 micron CMOS technology is used for fabrication in TSMC and the fabricated chip is with potential commercial application.
