宽动态的主要技术是采用特殊DSP(数字信号处理)电路,对明亮部分进行最合适的快门速度曝光,然后再对暗的部分用最合适的快门速度曝光,然后将两个图像进行DSP处理重新组合,使明亮的部分和暗的部分都可以看得清楚,这需要很高的技术使色彩和清晰度损失到最小。目前市场上的宽动态摄像机,无外乎采用三种方案,分别是:SONY(索尼)Dynaview+SS-Ⅱ方案、PIXIM CMOS+DPS方案及Panasonic(松下)SD Ⅲ方案。然而,我们今天CPS实验室的主角是基于LG电子XDI芯片新生的专业级高端超宽动态摄像机LS903P-3,下面我们一起来看看全新方案的XDI是如何实现传统DSP的超宽动态功能的。
Wide dynamic main technology is the use of special DSP (digital signal processing) circuit, the best part of the bright shutter speed exposure, and then the dark part of the exposure with the most appropriate shutter speed, and then the two images were DSP processing re- The combination makes it possible to see the bright and dark parts clearly, which requires high technology to minimize color and sharpness. Currently on the market wide dynamic camera, nothing less than the use of three programs are: SONY (Dynaview + SS-Ⅱ SONY program, PIXIM CMOS + DPS program and Panasonic (Panasonic) SD Ⅲ program. However, today’s protagonist of CPS Lab is LS903P-3, a professional high-end ultra-wide dynamic camera based on X-ray chip of X-ray LG Electronics. Let’s take a look at how XDI of the new solution realizes the wide dynamic range of traditional DSP.
