DOL WDR stands for digital overlap wide dynamic range, it's the next generation Sensor-based WDR technology exclusively developed by Sony.

Sony has launched several new CMOS image sensors to support DOL WDR function. The DOL WDR image sensors can output up to three frames of images alternately on each line, DOL WDR function requires a dedicated image signal processor to control and processing. However, DOL WDR can provide many advantages such as improved such as improved characteristics in low-light environments compared to conventional WDR that uses multiple frame set output. (See Figure 1.)

Figure 1: Single Exposure vs DOL-WDR

In challenging lighting conditions, DOL-WDR is capable of capturing both dark and bright part then combining the differences into a scene to generate a highly realistic image.
