Even if it is a hardcore mobile phone enthusiast, if you want to answer how many new mobile phones have been released recently, it is estimated that he will also need to take out his mobile phone to flip Baidu. In the highly competitive mobile phone market, to stand out, there are not a few eye-catching features. Impossible. But it allows users to immediately feel the difference, or take power in the camera function. So as a traditional camera phone brand, also brought 3-HDR technology on the new OPPO R15.

What is 3-HDR? (What is 3-HDR?)
OPPO R15The first use of the Sony IMX519 sensor is known to everyone, but What is the difference between 3-HDR and ordinary HDR? 3-HDR is an abbreviation of real-time classification exposure, and its principle is based on Based on the hardware-level optimization of the 'pixel reconstruction' technique used in R9 and R11s, a real-time hardware graded exposure can be achieved in a single process by using different exposure conditions between 4 sub-pixels in a large reconstruction pixel.
Compared to the synthesis of general HDR photos, 3-HDR is a real-time grading exposure that allows for finer picture quality. The former is synthesized by software, and the latter is the exposure control of each sub-pixel based on real-time lighting conditions. It is a physical HDR technology.
When the user is taking self-portraits in the backlight, 3-HDR can display the HDR effect after multi-frame synthesis in real time through the screen of the mobile phone. Not only the portrait is clear, the background is also clear, which is WYSIWYG. What you see is the final result. Imaging effect, which has not been achieved before which cell phone.
How is the actual effect
In daily use, the user only needs to keep the OPDR's HDR mode in automatic, because the phone itself will use the exposure of the face as a benchmark to automatically judge the HDR switch. In the self-timer mode, only see the 3-HDR flag. , It is known that the function is running. And 3-HDR does not affect other functions such as blurring, beauty, and the simultaneous use of filters. It can be said that 3-HDR greatly enhances the self-portrait of the OPPO R15.
The following picture is a self-portrait proof with three modes: depth of field blurring, beauty, and 3-HDR. The cooperation between them is also very good. The first is that 3-HDR accurately restores the exposure of the face, and then the beauty function The skin and temperament parts are retouched, and the final blurred background is a good complement to the sister herself. The 3-HDR gives people and the background exposure at a level that makes the picture look more natural.
In addition, we also noticed a very good optimization, that is despite the use of 20 million pixel high-resolution front camera, but OPPO R15 in 3-HDR mode does not appear obvious delay. The following figure also opens the virtual , beauty, 3-HDR, the uncle in the back of the sister did not appear nasty smear, instant feeling freeze is very good.
However, the main camera that supports the AI portrait mode, the effect of backlighting is very good, but does not support 3-HDR. Xiaobian thinks that in the later system update optimization, the main camera should also add support for 3-HDR. OPPO R15 will become a perfect backlight camera phone.
