Why is vivo S7 selfie so powerful? Here’s the answer

2020 can be said to be the first year of vigorous development of domestic 5g mobile phone market. When major mobile phone manufacturers launch their own 5g mobile phone products, they also bring a lot of innovation and progress in mobile phone image. As the head manufacturer of domestic smart phones, vivo launched its own 5g image flagship, vivo X50, in June. Its powerful image strength of the rear camera once caused heated discussion in the industry. < / P > < p > in fact, vivo has not given up the exploration of self photographing technology of mobile phone front camera while bringing users a powerful experience of taking pictures with rear camera. Not long ago, vivo launched a new lightweight self timer flagship, vivo S7. So, what is the strength of the vivo S7, which is known as the “selfie benchmark”? Today, let’s have a good study. < / P > < p > when we talk about mobile phone selfie, we can’t get around a basic topic – camera configuration. You know, the mobile phone needs to complete the photo taking work through the CMOS sensor. In a sense, the quality of mobile phone sensor directly determines the final image quality. < / P > < p > compared with the front single camera configuration of traditional smart phones, vivo S7 adopts a dual camera combination of 44 million pixels of front main camera + 8 million pixels of front ultra wide angle lens. It is worth mentioning that this front main camera is the first Samsung isocell slim GH1 sensor, with a sensor area of 1 / 2.65 inch and supporting EIS anti shake. In an environment with sufficient lighting conditions, the 44 megapixel UHD master camera can bring amazing resolution of the self shot sample; even in dark light environment, thanks to the F / 2.0 super large aperture, the guarantee of sufficient light input can also provide clear and bright imaging effect. < / P > < p > at the same time, the front camera of vivo S7 is also equipped with phase detection auto focusing technology used in SLR. With the help of autofocus technology, vivo S7 can focus from 15cm to infinity. Through the self-contained eye focusing function, clear and accurate focusing can be obtained regardless of the self shooting distance, so as to provide users with stable and high-quality selfie. In terms of software algorithm, vivo S7 also upgrades super night scene self timer 2.0 algorithm to optimize the night scene input effect. AI image enhancement technology can enhance the details of the portrait, and can enhance the skin color of the face under dark light conditions, and restore the real face of the face, so as to further enhance the self portrait experience under dark light conditions. < / P > < p > after finishing the front main camera of vivo S7, let’s talk about this 8 megapixel front super wide angle lens. Ultra wide angle lens, as the name implies, is a lens that can bring a larger viewing range angle when shooting. So, what is the significance of adding this 8 megapixel ultra wide angle lens to the front camera of vivo S7? < / P > < p > here, let’s make a parameter comparison: the 8 megapixel ultra wide angle lens of vivo S7 has reached 105 ° and the range of view is twice as large as that of the ordinary 78 ° lens. This means that you can use a larger front view to take a larger self shot. Well, one of the advantages of this lens is obvious – it’s a magic weapon for a group photo of many people! With the blessing of this front super wide angle lens, my mother doesn’t have to worry about not taking all of you when I take a group photo! < / P > < p > in addition, because of the unique perspective deformation of the wide-angle lens, the portrait will be extended in a certain range. When using the vivo S7 front wide-angle lens to take a single self shot, you can easily take “supermodel photos” of long legs and small faces. The addition of the front ultra wide angle lens can also realize the depth of field calculation at the hardware level, which can provide a more natural background virtualization effect to highlight the characters in the focus of the screen. At the same time, vivo S7 also supports pre virtual mode. Users can adjust the size and shape of light spot in real time to enhance the artistic beauty of self portrait. < / P > < p > on the whole, the addition of front-end dual camera, from the hardware configuration, can effectively guarantee the stability of the selfie sample, and also bring about more functional changes of self portrait. < / P > < p > for the experience of mobile phone self shooting, powerful hardware creates an excellent imaging foundation for it. If you want to take more beautiful and moving self portraits, you need another mysterious protagonist, beauty algorithm. < p > < p > < p > “beauty” is a deep learning + image processing + graphics technology, it involves face detection, face key point positioning, face thinning, skin grinding, whitening and other professional technical concepts, here we will not expand on more. All we need to know is: the rich beauty function in the mobile phone can make your self portrait look more natural and beautiful, thus showing different charming styles. < / P > < p > so, what kind of beauty enhancement does vivo S7 bring this time? Here, we need to briefly review the development process of vivo s series: from vivo S1’s first lift front camera, to vivo S5’s “5-fold super texture beauty”, and then to vivo S6’s super clear night scene self shooting, each generation of vivo s series is constantly innovating to explore the limits of self shooting technology. < / P > < p > while inheriting the rich beauty functions of the previous generation products, vivo S7 has further evolved: five super texture beauty 3.0, skin grinding, optimization of skin color and facial features fine molding are at your fingertips; multi style 3.0, users can use a variety of creative filters to match their own style; super night scene selfie 2.0, based on raw domain algorithm, is upgraded again, adding more exposure levels and richer portrait details; small head function makes the head shoulder ratio more coordinated < / P > < p > in addition, there are many functions such as changing makeup with one button, double exposure, one button plog and one button vlog. In terms of the richness of beauty function, vivo S7 can be said to be the best in the same kind of products. The rich self portrait beauty function brings new possibilities for more beautiful self portrait. < / P > < p > at the same time, vivo S7 has achieved the ultimate performance in the light and thin fuselage. In the environment of 5g mobile phone weight breaking through 200g, vivo S7 did not choose to compromise. 170g fuselage weight, 7.39mm fuselage thickness, such an excellent achievement is that the R & D personnel experienced many challenges, optimized the five internal hardware of the fuselage, and finally achieved such a slim result. This rigorous spirit of exploration is really rare and valuable. < / P > < p > while subtracting the weight of the fuselage, vivo S7 is not “shrunk” in terms of texture and design. In terms of fuselage technology, vivo S7 keeps improving and adopts Ag sanding process consistent with Huawei P40 pro, iPhone 11 Pro / max, vivo X50 and other high-end models, providing users with double enjoyment of vision and touch. The continuation and innovation of the two-color cloud scale design concept has further improved the product identification of vivo S7. < / P > < p > in general, the launch of vivo S7 is another in-depth exploration and product layout of vivo mobile phones in the field of professional self portrait. Its appearance further strengthened the comprehensive camp of vivo mobile phone. In general, vivo S7 is a breakthrough in the field of self portrait beauty in the industry, and it is also a new height of self portrait mobile phones. Selfie flagship really deserves its reputation. Huawei has finally made a choice! Xiaomi and ov have also followed up. Have you ever thought about today?
