WDR

Wide Dynamic Range (WDR) is an image processing technology used to simultaneously display both bright and dark details within the same image. In traditional photography or videography, when capturing high-contrast scenes, issues often arise where bright areas are overexposed (losing detail) or dark areas lose detail. This happens because the camera's sensor cannot capture both the highlights and shadows simultaneously. WDR addresses this by combining images taken at different exposure levels to ensure that the final output retains details in both bright and dark areas.

Specifically, when capturing a scene with high contrast, the camera takes multiple shots with different exposure times to capture details in various regions. These images are then merged using algorithms to produce a single image with a wider dynamic range, preserving details across the entire image.

WDR technology is widely used in surveillance cameras, car dash cams, digital cameras, and other fields to provide more realistic, clearer, and detail-rich images. It allows for the display of more details in both bright and shadowed areas simultaneously, improving image quality and visibility.
