友善之臂500万 高清摄像头CAM500A OV5640配Tiny4412 Android源码


简介
CAM500A摄像头模块主要采用了Omni Vison公司的1/4英寸QSXGA CMOS OV5640图像传感器模组,并通过并行数字视频接口DVP与ARM主板连接,最高可支持500W像素(2592x1944)拍照,最高支持720P@30fps流畅高清录像,支持多种自动图像控制功能,如自动连续对焦(AFC),自动白平衡(AWB),自动曝光(AEC)等功能。
CAM500A模块采用了焦距为2.7mm,固定光圈2.8,视角66°的微型镜头,整个模块尺寸大小为33.7x25mm,并带有2.mm孔径的正方形螺丝定位孔,采用3.3V供电,可使用24pin FPC软排线与外部主控板连接使用。适用于智能监控,无线智能小车,无人机等产品项目的开发应用。
注意: 以下所列模块特性仅适用于友善之臂公司ARM主控板连,OV5640模组本身可支持更多功能特性,请自行研究使用。
