资 源 简 介
基于ICX229AK 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多格式显示。在FPGA中实现了自动聚焦、自动光圈等功能，并扩展了鼠标驱动及划线、OSD显示等实用功能。通过PW1226滤波放大处理，完成了PAL制数字视频信号到VGA格式的转换，分辨率可达到1 024×768。实现了复合视频、S-VIDEO和VGA 3种视频信号的同时输出。该一体化摄像机可用于视频展台及实时监控等方面，大大提高了输出图像质量。
Abstract:
Based on the ICX229AK image sensor chipsets from SONY， PAL integraTIve camera with VGA interface is designed in this paper. Under the DSP+FPGA+ASIC architecture， the capture of the video signal and mulTI-formats display are completed， and key technologies of auto-focusing and auto iris are executed in the FPGA. Some new type pracTIcal funcTIons such as mouse driver， OSD display， etc are expanded. The image is zoomed by PW1226. Eventually， the PAL digital video is converted to the VGA format， the resolution is up to 1024×768. The designed camera includes three outputs of composite video， S-VIDEO and VGA video signals， and can be used for video presenter， real-time monitoring and so on. It greatly enhances the quality of the image output.
