The application of HDR technology can enhance the image detail and dynamic range, making the picture more realistic and more layered, thus effectively enhancing people's viewing experience, so what is the difference between SDR and HDR?
SDR is Standard Dynamic Range, and HDR is High Dynamic Range. As the name implies, HDR has a wider dynamic range and can present more details in the dark and bright parts of the picture. Of course, to view HDR images, you need both the monitor and the source to support HDR.
High-Dynamic Range (HDR) images, compared to ordinary images, can provide more dynamic range and image detail, according to the different exposure times of the LDR (Low-Dynamic Range) images, the use of each exposure time corresponds to the best details of the LDR image to synthesize the final HDR image, can better reflect the visual effects of the real environment.
HDR technology brings the picture quality improvement is intuitive and perceptible, even the general audience can discern with the naked eye, so many manufacturers have equipped HDR technology on their TV products this year.
In terms of detail, the same image in SDR is a curve between 1 and 100 connected by dots with a pitch of 1. In HDR, it is a curve between 1 and 1000 connected by dots with a pitch much smaller than 1. The latter, of course, can better represent the gradations and levels of light and color in an image, and therefore can capture more detail in the image between light and dark.
