In recent years, the field of mobile imaging has developed rapidly, especially the development of rear-mounted multi-camera technology, which has brought us a brand-new mobile photography experience. As a leading player in this field, OPPO has been committed to the development of mobile images, especially with OPPO’s unique understanding to interpret how mobile images should develop and move forward. On March 11, the release of OPPO Find X3 series new products brought us a new idea of OPPO’s development of imaging systems.
OPPO Find X3 series rear imaging system is 50 million wide-angle IMX766+50 million ultra-wide-angle IMX766+13 million telephoto lens (up to 5 times hybrid optical zoom, up to 20 times digital zoom) + 3 million microscope lens (up to 60 times zoom ). This imaging system first has full-focus imaging capabilities, from wide-angle to up to 20x zoom scenes can be shot; secondly, OPPO Find X3 supports optical image stabilization and electronic image stabilization, and the shooting stability is guaranteed.
What needs to be analyzed is the IMX766 used in the main camera and wide-angle. OPPO has always had the tradition of customizing flagship sensors with Sony. This IMX766 is the latest flagship sensor jointly customized by OPPO and Sony. This sensor has a 1/1.5 6-inch outsole, a single pixel of 1μm, and a combined pixel size of 2μm. A new focusing method is adopted to maintain a clear and stable focus effect during shooting. In addition, the IMX766 sensor supports 1 billion colors, and the color performance of the final image has been determined from the hardware level.
The biggest change brought about by 1 billion colors is to make the transition of collected color information more natural and smooth. In the proofs, each color gamut has distinct colors. In addition to hardware support, OPPO software optimization skills should not be underestimated.
It should be noted that the OPPO Find X3 series models shooting 1 billion colors can make the shooting screen show a more delicate gradation effect, while most monitors/smartphone screens are still at the level of 16.7 million colors. Although display devices that natively support 1 billion colors exist, they are not widely used, and third-party adaptation is an important issue. In response to this problem, the OPPO solution is to provide a “full-link color management system” that can display 1 billion colors from information collection to processing to final presentation.
The flagship main camera CMOS is modified to be used as a wide-angle camera. It is not the first of the OPPO Find X3 series. The OPPO Find X2 series has the first IMX586 flagship CMOS to be changed to a wide-angle. force. Below, we use proofs to show the actual image expressiveness of OPPO Find X3 series models.
In order to test the overall performance of the imaging system, we show the real shot effects of the OPPO Find X3 series from the aspects of wide-angle, ultra-wide-angle, night scene, and microscope modes.
As we mentioned above, the main camera CMOS IMX766 is jointly developed by OPPO and Sony. It is very important in sensor size (1/1.56 inch outsole), single pixel area size, number of pixels, focusing ability, HDR, etc. Excellent qualities. It is easy to take a good proof in a well-lit place.
In terms of wide-angle camera performance, the OPPO Find X3 series presents the imaging characteristics of abundant picture details and full color. It is easy to take photos with texture, which is of great benefit to recording the details of life.
In the above wide-angle sample, the subject is a fair-faced concrete building. After the fair-faced concrete building is formed, the surface will be oxidized to form rich color details. In the whole photo, whether it is the wall color transition or the glass reflection, there is a good color transition, and the picture is full of tension.
This wide-angle lens expresses more real and delicate color details, rich colors, smooth and natural color transition, leaving a sense of hierarchy. Make full use of the high-color advantage bridge deck to solve the problem of color deviation that may be encountered during shooting, and the color expression is accurate. On the main camera, the OPPO Find X3 series guarantees the details and color performance of the picture. Let’s look at the ultra-wide-angle performance below.
The biggest function of the ultra-wide-angle lens is to store the whole view of the landscape, such as the whole view of the building. Although ultra-wide-angle lenses are widely used in smartphones, the actual shooting experience may not be excellent, and the OPPO Find X3 series dual main cameras are solving this problem. OPPO Find X3 series models use IMX766 as the ultra-wide-angle sensor, which is undoubtedly the strongest ultra-wide-angle of the current mobile terminal. Coupled with the inherently large viewing angle of the ultra-wide-angle lens, it can easily take high-level samples.
Compared with the wide-angle real shots, it is not difficult to see that this flagship ultra-wide-angle sensor, while ensuring the color of the picture, takes into account the width and the details of the picture, and shoots the color transition in the sunset environment. The color transition of the sunset scene will be more intense, and the requirements for the color transition of the picture are higher. When shooting, the sun is “embedded” under the crane. At that time, the color transition of the sky and the shooting effect are almost zero error. In addition, shooting against the sunset also has a certain The attribute of’backlighting’, the concrete chimney is dark from the top to bright below, which is exactly the same as the real visual feedback.
With the cooperation of software algorithms, OPPO Find X3 series models can easily capture the atmosphere of the shooting scene, and the edge position of the screen has little distortion. It can be seen that the cooperation of software and hardware achieves a good wide-angle effect. The above wide-angle/ultra-wide-angle proofs comparison is not difficult to see the OPPO Find X3 series dual main camera shooting characteristics:
First, the two main cameras are based on 1 billion colors, and the color processing of the picture is more realistic and natural, and loyal to the naked eye; secondly, the wide-angle and ultra-wide-angle samples both present a pure and bright picture with comfortable colors, showing the actual experience of the dual-main camera. Excellent quality in use.
Night scene shooting . Compared with the daytime proofs, the complex environmental changes at night obviously test the imaging performance of an imaging flagship. Before the test, I was very confident about the night scene capability of OPPO Find X3 series models. After all, there is an outsole sensor placed there, and there are also good night scene optimization and AI scene enhancement functions. OPPO Find X3 series models have a good shooting performance. Can be expected.
In night scene shooting, the OPPO Find X3 system model suppresses over-bright areas and brightens over-dark areas. The effect is high-quality night scene photos with no highlights but no exposure, dark parts with details, and no obvious noise. Especially the details of architectural lighting and shadow processing, the picture quality is pure, and the look and feel is transparent.
Microscope mode is a brand new concept introduced by OPPO Find X3 series. Unlike the traditional macro mode, this microscope lens uses a more advanced optical lens module. With this microscope lens, we can see a lot of things that are not visible in the conventional field of view. . This microscope lens has an LED aperture around it, which mainly serves as a supplementary light. How is the actual performance? Let’s take a look at the proofs.
The actual test is not difficult to see that this microscope lens focuses on details that are difficult to be observed by the naked eye. Moreover, the photos emitted by this microscope lens still retain enough details of the picture. The uneven particles on the surface of the stone are recorded by this microscope lens, and the whole photo is full of subtle beauty.
We used this microscope lens to aim the cherry tomatoes. The skin of the cherry tomatoes seems to be smooth. In the microscope mode, we can still see the fine linen holes in the skin. It turns out that there are so many secrets in the smooth skin of cherry tomatoes. During the test, the details of this lens are good.
We increased the difficulty of the test by aiming the microscope lens at the screen of the mobile phone. Unexpectedly, this lens captured the pixel arrangement of the screen clearly. For evaluation agencies like Zhongguancun Online, you don’t need to prepare professional equipment to look at the pixel arrangement of mobile phones in the future. What the screen arrangement is, you can tell with a single shot with the Find X3 series models. This function is not available in other mobile phones. With the help of the microscope lens, we can see scenes that are usually ignored or completely invisible.
Above, we tested the image expressiveness of OPPO Find X3 series from four aspects: main camera, wide-angle, night scene, and microscope. The actual effect still left a deep impression on us. The main camera’s control and restoration of colors, wide-angle picture expression, night scene restoration, precise zooming effect, high filming rate, and super performance of macro, all give We were impressed.
Through the above sharing of real shooting experience, I believe that everyone has an intuitive understanding of the imaging capabilities of OPPO Find X3 series models, and also sees OPPO’s development and control of imaging technology. On the basis of customized hardware, OPPO uses software algorithms to study consumer research on mobile image usage scenarios, which are concentrated in the OPPO Find X3 series models, especially the addition of the dual-main camera concept, which indicates the development and exploration of mobile images. New Direction. It can be seen that OPPO has been using technology to solve consumer use problems, and through technology to allow consumers to experience new ways of playing and new fun in photography.
