Answer 2

hi everyone , this is your answer .The multiple exposure-type WDR outputs one set of two or four frames with different exposure times. ... Sony IMX290， IMX224, IMX225, IMX123 CMOS image sensors can support DOL-WDR. Sony introduced the DOL-HDR technology which has been used in recent developed CMOS image sensors ...This tells you the range where the WDR works . The higher the ratio, the greater the difference between the low light and high light spectrum that the camera can capture and the better ...
