How WDR Dash Cams Works

The magic behind the WDR dash cam lies in its unique approach to processing images. While a regular camera takes a single picture at one exposure level, a WDR dash cam takes multiple pictures at different exposure levels within a split second.

It then combines these images into one, creating a balanced and detailed image that accurately represents both the dark and light areas of the scene.

To understand it better, let's break down the process:

Capture Multiple Frames

The WDR dash cam captures several frames of the same scene at different exposure levels. One frame is exposed to capture the details in the darker areas, while another is exposed to capture details in the brighter areas.

Image Processing

The captured frames are then processed using an advanced image sensor and processor. These components work together to merge the images, taking the best details from each frame.


The different exposures are combined to create a single image where both dark and bright areas are clearly visible.


The final image is outputted as a video frame in the dash cam's recording. This happens so quickly and seamlessly that the driver or viewer can't tell multiple exposures were combined.

This sophisticated process happens continuously as the dash cam records, ensuring all footage captured offers a wide dynamic range. The result is high-quality video, even in challenging lighting conditions.
