WDR is the narrowing of the Wide Dynamic Range , commonly known as the wide dynamic, which is the ratio of the maximum brightness signal value of an image to the minimum brightness signal value that can be resolved.

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

The DOL-HDR image sensors can output up to three frames of images alternately on each line, DOL-HDR function requires a dedicated image signal processor to control and processing. However, DOL-HDR can provide many advantages such as improved characteristics in low-light environments compared to conventional WDR that uses multiple frame set output.

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

Sony IMX290 CMOS Image Sensors support DOL-HDR. Please check DOL-HDR effect:
