Tell you: how strong is HDR video recording supported by hardware

The figure above is HDR A sample of a picture. At the launch of Find 5, we learned that it was the world's first smartphone with HDR supported hardware. It supports HDR videotape , none of the previous mobile phones can do that; It can also preview in real time without post compositing. You can see the effect before using Find5 to shoot. You can select the best composition and light, and then press the shutter to take the most beautiful picture. How powerful are HDR enabled phones? Make up science popularization.

What is HDR?

HDR is the abbreviation of High Dynamic Range. When shooting in a high light ratio environment, ordinary cameras cannot record extremely bright or dark details due to the limitation of dynamic range. The photos processed by HDR program can obtain better levels than ordinary photos in both high light and dark positions, even in the case of high light ratio. The so-called "dynamic range" refers to the ratio of the maximum value to the minimum value of the signal that the image or image device can represent.

Benefits of HDR?

HDR technology can correctly restore the light and dark details in photos, and improve the color tolerance of photos. HDR photos enhance the color and level of the scene, making the picture more powerful. Let's take a look at the following two pictures:

The following is a general sample

The following figure shows the sample after HDR processing

Let's look at another group. One group is an ordinary sample

One is HDR sample

The above is just a sample comparison of HDR pictures. What about the HDR videos we know? You can clearly feel the power of HDR through the picture samples.

Digital camera manufacturers are also constantly focusing on the development of hardware and built-in functions for shooting higher dynamic range. Fuji is the best among them. As early as 2004, it launched the SuperCCD SR with high dynamic range, which uses half of the pixels to record the normal brightness and the other half to record the dark position of the picture, and is applied to its digital SLR S3 Pro. Later, other brands of digital SLR cameras have also introduced computing functions to improve the dynamic range of images, such as Nikon's Active D-Lighting, Canon's highlight priority mode, Pentax's dynamic range expansion function, and Sony's D-Range Optimizer, which can improve the level of photos in a simple way. Later, even small DCs began to add high dynamic range functions, such as some models of Fuji, Nikon and Ricoh.

While the hardware of Find 5 supports HDR video recording function, theoretically:

You can preview in real time without post compositing. You can see the effect of shooting before shooting. You can select the best composition and light, and then press the shutter to take the most beautiful picture. To bring HDR video and ordinary video live shot for everyone, we want to compare the video:

Finally, the official promotional video of OPPO Find 5 about HDR photography and 120 fps high-speed photography:

Summary

Many people pay close attention to the Find 5 mobile phone released by OPPO yesterday, the 1080P screen. The world's first hardware supports HDR real-time video recording, and the first one supports 120 frames/second high-speed video recording. These are revolutionary advances. Xiao Bian is also looking forward to the arrival of this mobile phone like O fans! But I hope that these are not only conceptual, but also can experience the specific later evaluation in the actual product, Love to play computer games It will be released at the first time.
