Aptina的AP0100CS可与其市场领先的低光照CMOS传感器产品结合，创建具有高分辨率和标准动态范围(SDR)或宽动态范围(WDR)的CCTV相机解决方案。AP0100CS集成了Aptina的先进图像处理管道(pipeline)，具有令人惊叹的视频和低光照性能。借助用于宽动态范围图像再现(rendering)的高级局部色调映射(Advanced Local Tone Mapping, ALTM)功能，即使在非常困难的高对比度照明条件下也能够生成高质量的视频。AP0100CS集成了具有高级转换器功能的NTSC/PAL编码器，可以提供模拟CCTV市场所需的高TV线分辨率。这款产品为中国市场设计人员提供了过去无法获取全新相机设计方案;也就是说，能够利用高端IP相机传感器的高分辨率、内在的卓越低光照性能及WDR能力，移植应用于模拟CCTV监控领域。这种强大的设计灵活性将会带来令人激动的新型监控摄像机。
Auto Exposure(自动曝光)
The auto exposure algorithm optimizes scene exposure to minimize clipping and saturation in critical areas of the image. This is achieved by controlling exposure time and analog gains of the external sensor as well as digital gains applied to the image. Auto exposure is implemented by a firmware algorithm that is running on the embedded microcontroller that analyzes image statistics collected by the exposure measurement engine, makes a decision, and programs the sensor and color pipeline to achieve the desired exposure. The measurement engine subdivides the image into 25 windows organized as a 5 x 5 grid.
