具有VGA接口PAL一体化摄像机设计
首发时间:2009-03-14
摘要:基于SONY的ICX229AK PAL制CCD芯片组,设计了具有VGA接口的一体化摄像机。采用DSP+FPGA+ASIC的构架,完成了视频信号的采集和显示。在FPGA中实现了自动聚焦、自动光圈等关键技术,并扩展了新型的如4副图像存储、鼠标驱动及划线、实时图像与存储图像同屏对比、OSD显示等实用功能。通过PW1226将帧率提升到60帧/秒,并对图像进行放大,最终完成了PAL制数字视频信号到VGA格式的转换,分辨率为1024*768。实现了复合视频、S-VIDEO和VGA三种视频信号的同时输出。可用于视频展台及实时监控等方面,大大提高了输出图像的质量。

The Design of PAL Integrative Camera with VGA Interface
Abstract:Based on the group of SONY Company ICX229AK PAL image sensor, a PAL integrative camera with VGA interface is designed in this paper. Using the DSP + FPGA + ASIC architecture, it completed the acquisition of the video signal and display. And achieved key technologies of auto-focusing and auto iris in the FPGA . And expanded new type practical functions such as four images storage, mouse drive, real-time images and stored images comparison in the same screen, OSD display, etc. The frame was converted 60Hz and image was magnified by PW1226. And eventually completed the PAL digital video signal to the VGA format conversion, the resolution is 1024 * 768. It achieved composite video, S-VIDEO and VGA video three signals output at the same time, And can be used for Real-time Monitoring, video presenter and so on, And greatly enhanced the quality of the image output.
Keywords: PAL VGA FPGA auto-focusing image magnification
