Wide Dynamics (WDR) is an image processing technology used to display both highlights and dark details in the same image.
In traditional photography or photography, when there is a high-contrast scene, there is usually a problem of bright overexposure (loss of detail) or loss of dark detail. That’s because the camera’s sensors can’t capture both bright and dark details. Wide dynamic technology works through multiple frame exposure, image synthesis, intelligent algorithms, and so on.
The basic principle of wide dynamic technology is to fuse low and high exposure images, so that the final output image can retain details in both the bright and dark parts. Specifically, when taking a scene with high contrast, he takes multiple photos continuously, capturing the details of different areas at different exposure times in each photo. The photos are then algorithmically synthesized into an image with a wider dynamic range.
Wide dynamic technology is widely used in surveillance cameras, car driving recorders, digital cameras and other fields to provide more realistic, clear, and detailed images. It can show more detail along with strong light and shadows, improving image quality and visibility.
In conclusion, wide dynamics is an image processing technique that presents highlighted areas and dark details to provide images of a wider dynamic range.
