The Design of PAL Integrative Camera Based on FPGA

Based on the group of SONY Company ICX229AK PAL image sensor chipset, PAL integrative camera with VGA interface is designed in this paper. Using the DSP + FPGA + ASIC architecture, it completes the acquisition of the video signal and display, and achieves key technologies of auto-focusing and auto iris in the FPGA. Some new type practical functions such as four images storage, mouse driver, real-time images and stored images comparison in the same screen, OSD display, etc are expanded. The frame is converted 60Hz and the image is magnified by PW1226. Eventually, it completes the PAL digital video signal to the VGA format conversion; the resolution for 1024*768. It achieves composite video, S-VIDEO and VGA video signals three outputs at the same time, and can be used for real-time monitoring, video presenter and so on. It greatly enhances the quality of the image output.
