https://oatao.univ-toulouse.fr/311/1/MartinGonthier_311.pdf 要說手機的HDR比較先進,是講得通的,我看到過一篇HDR感光器的論文,手機用的實時HDR感光器印像中也有產品了,不過實時HDR的原理不是手機在RAM拿資料分析,而是這樣 A novel principle has been developed to build an ultra wide dynamic range digital CMOS image sensor. Multiple integrations are used to achieve the required dynamic. Its innovative readout system allows a direct capture of the final image from the different exposure time with no need of external reconstruction. The sensor readout system is entirely digital, implementing an in-pixel ADC. Realized in the STMicroelectronics 0.13μm CMOS standard technology, the 10μm x 10μm pixels contain 42 transistors with a fill factor of 25%. The sensor is able to capture more than 120dB dynamic range scenes at video rate. 我英文不夠好所以不能全段翻譯,但大意就是這種HDR感光是直接讀取疊加好的HDR圖像,不用外部處理器重構影像,所以HDR實用程度會比連拍+疊圖的後制HDR要好
