What does hdr video mean

HDR video means high dynamic range image. It has larger brightness data storage than other formats of images; and the way it records brightness is different from traditional pictures, instead of using a non-linear method to convert brightness The information is compressed into an 8-bit or 16-bit color space, and the brightness information is recorded in a direct corresponding manner.

What does hdr video mean?

HDRI is the abbreviation of High-Dynamic Range (HDR) image, which is a high dynamic range image. It was invented to solve the problem of better storing high dynamic range images.

Simply put, HDRI is an image with a very wide brightness range, which has greater brightness data storage than images in other formats. And the way it records brightness is different from traditional pictures. Instead of compressing brightness information into an 8-bit or 16-bit color space in a non-linear way, it records brightness information in a direct corresponding way.

HDR introduction:

HDR refers to high dynamic lighting rendering. HDR is a processing technology that improves the brightness and contrast of images. Compared with ordinary images, , HDR can provide more dynamic range and image details, and use the LDR image corresponding to the best detail at each exposure time to synthesize the final HDR image, which can better reflect the visual effects in the real environment.

HDR is a processing technology that improves the brightness and contrast of images. This technology can enrich the details of each dark part, make the dark places darker, and enrich more detailed colors, making movies, pictures, and game screens All can present excellent effects, allowing users to get closer to the visual experience in the real environment when watching movies and playing games. The maximum brightness of traditional SDR (standard dynamic range) is only 100 nits. Parts of the picture above 100 nits will be distorted (lost). The minimum debugging is 0.1 nits. Parts of the picture below 0.1 nits will be lost. HDR technology can make the highest brightness reach thousands of nits and the lowest brightness reach 0.0005 nits, greatly expanding the details of parts of the picture with brightness above 100 nits and below 0.1 nits, while making the entire picture look more transparent Bright and detailed.
