How the 50-megapixel camera work on OPPO Find 7?

OPPO F7-01

Recently, OPPO has been announced the example images of upcoming OPPO Find 7 camera capability, the camera has 50 megapixel that offers good quality and impressive picture.

This against Nokia, that now already has 41 megapixel lens through Nokia Lumia with PixelView technology. Almost equal to the SLR. OPPO beyond the trend, and how the 50-megapixel camera work on OPPO Find 7?

Originally according to Nokia’s principle, 50 megapixel requires a large CMOS area. In OPPO Find 7, that use of 1.1 micron back-illuminated CMOS, CMOS counted down the diagonal is 11.22mm, so about 1/1.4 CMOS. This size is smaller than 808 1/1.2, 1/1.5 slightly larger than 1020, it is possible to do, the camera section thickness OPPO process will be more than 10mm.

The advantage of this approach is the real deal pixel picture quality is real, and can synthesize a plurality of pixels, a very good image quality in low light environtment.

The disadvantage is that the price is very expensive, lenses and motors also need to customize. And CMOS manufacturers are reasons to accept orders also an issue.

With OPPO Find 7 exposure invitation letter, 2,145,000, describes the use of the 13 million Sony IMX214 camera, the end of this conjecture.

The published proofs of view, is not a simple interpolation. Because the 13 megapixel to 50 megapixel is a simple interpolation, details will be very rough. Because Sony’s 1.1-micron CMOS single-pixel particles have been on less than ideal, then it is difficult to accept the interpolated image quality.

Most probably, the Multi-Shot technology, is a shooting technique to generate multiple photos.

The technology itself is not new, HDR is the result of the application of this technology. HDR is a shot generate multiple photos with different metering, final software synthesized. Bright place, a dark place can see. Because it was shot a few, after the creation of HDR photos a little longer, and later with hardware HDR, you can speed things up.

In addition, multi-frame noise reduction is also applied multiple exposure shooting a scene, generating multiple photos, and then put these photos to an increased amount of information, to eliminate noise, strengthen detail, enhance quality purposes.

Multi-Shot technology as well as an application is to increase the pixels. One shot generate multiple photos, pixels to make a deviation, then the software synthesis. Thus more than 13 million pixel photos synthesis of 50 million, because there is a true original pixel information, the quality is much better than the 13 million to 50 million direct software interpolation.

OPPO Find5 HDR is one of the early use of hardware manufacturers, using multiple shooting (Multi-Shot) to enhance the number of pixels is also surprising on Find 7.

a new breakthrough in mobile phone camera

Multi-shot (Multi-Shot) upgrade pixel technology, Hasselblad has used previously, when a processor bottleneck is asking for too much, software synthesis is too slow, difficult to spread. But in recent years with the development of smart phones, mobile processor performance has been terrible, can and early dual-core computers compared. Processor bottleneck on camera is the problem, the phone is not a problem. The use of multiple shooting (Multi-Shot) to enhance the pixel Ye Hao, Ye Hao multi-frame noise reduction is a good way to improve quality.

OPPO off to a good start, if this idea is used by everyone, then Elife E7 can make 64 million pixels. The Nokia 1020 can make 164 million pixels (if the processor and the memory bandwidth is able to stand it).

If the popularity of multi-frame noise reduction, now in 13 million, 16 million, 41 million-pixel camera phone picture can be taken a big step forward. Comparable to entry- SLR is not impossible.

Processor performance to lack of hardware and software to solve problems, improve quality, OPPO off to a good start.
