The four corners of the screen for a smaller radius of the chamfering process, which ensures that the full screen display will not lose too much screen while also avoiding the narrowing of the upper and lower border and the right angle of the screen split.

vivo X20Plus Using a full-face metal surface of the fuselage design, the whole back is not a flat. Take in the hand, continuous curved curvature can be a good fit the palm of your hand, grip is very comfortable, like drawing tools in the drawing In the contraction of the narrow oval. Ultra-thin waist and On-Cell full fit technology to vivo X20Plus In the visual is very slim.

Of course, this design is not only for better grip feel, large curvature of the raised frame can be a positive full screen to play a good protection of the fall.

Studio shot: data will not lie color reproduction degree of outstanding performance

The essence of the photo is inseparable from the resolution of resolution, color orientation, white balance, tolerance and other dimensions, so our evaluation criteria to start the standard camera environment, build a dataable photo template, while the use of Imatest software quantitative test data, True and reliable evaluation results.

1, resolution

Resolution is the ability to distinguish the details of the original, the better the resolution of the control of the better, the details of the transition part of the more natural.There are many ways to test the resolution, where we choose the linear test method, it The advantage is very intuitive, with the naked eye can be observed, we intercept the test sample part of the location as a test area, test vivo X20Plus camera resolution.

vivo X20Plus Results for the 1800 line, the same price is in the superior level.

2, white balance

The white balance is an indicator of the white precision after the combination of red, green and blue trumpets, and many people encounter problems when using a digital camera: the images taken in the room of the fluorescent lamp will appear Green, in the indoor tungsten light shot out of the scene will be yellow, and in the sun shadows at the pictures taken inexplicably blue, the reason lies in the 'white balance' on.

vivo X20Plus White balance of the results of 0.01, full of scores, showing the color is also closer to the real.

3, color deviation value

Shoot the 24 Color Check test card in the environment, through the Imatest analysis to obtain the color deviation value ΔE and white HSV saturation. Color difference ΔE is actually measured color and true color gap, the greater the gap, the more serious color cast.

vivo X20Plus Of the color deviation of 12.8, is a moderate level, color control to be improved.

4, dynamic range

In the photographic technology, the dynamic range refers to the brightness range of the subject - the darkest point of the object to the brightest point of the brightness span. Shooting studio environment in the gray color card, through the Imatest calculation and analysis of the dynamic range of the camera.

vivo X20Plus Of the dynamic range of 6.31, the performance of full marks.

Take pictures: beauty on the basis of a clear yet natural

Camera, vivo X20Plus and X20 using the same camera module, thanks to the full pixel dual-core focus, using a 2x1200 million +500 million pixels dual photo combination, the main aperture f / 1.8, vice f / 2.0.

On the whole pixel binuclear focus Here editor to camera white identity for everyone to explain: We refer to the pixel, refers to the sensor responsible for optical - electrical signal conversion diode number, and the current market, most of the mainstream mobile phones Using PDAF phase-focusing technology, the sensors used in these phones have only one photodiode per pixel.

Two pixel photodiodes are arranged on each sensor using a full-pixel focusing technique, so that two image signals can be obtained at the time of photographing.When the signals of two photodiodes of one pixel can coincide with each other, It is judged that the focus is successful, and when the two signals can not coincide, the amount of lens driving required to complete the focus can be calculated based on the amount of deviation of the two images, so that the focusing speed is naturally more quickly and This design can achieve autofocus and image capture without affecting quality.

In addition, compared to X20 is different, vivo X20Plus Joined the hardware-level image magic square DSP chip, which is a 256MB RAM with a separate DSP image optimization chip, the image processing speed will be faster.In addition, vivo X20Plus Also supports OIS multi-axis optical image stabilization, can achieve as fast as 0.03 seconds of focus speed, and in low light environment shooting effect will be more advantages.

Is the mule is Mara out yo, see the next photo:

Daytime, facing the sunshine of the shooting environment X20Plus Automatically turn on the backlight mode, the camera uses the key metering and enhance the accuracy of exposure, and increase the EV value to avoid the theme too dark.You can see the sample to keep the color transparent at the same time, without losing the clear.

Indoor X20Plus In the detection of the surrounding environment yellow, light dim, it will automatically adjust to warm tone, the focus on the book, can be clever to the background of the virtual, and further highlight the elegant environment in the library.

vivo X20Plus It seems to have a unique view of food, the same use of the background blur function, highlighting the top of the chicken, shooting bright and not rich, people can be delicious, vegetables also shoot a fresh green, accurate color reproduction to make it Close to the human eye to see the picture.

Front also has full pixel dual-core focus, with 2x1200 million pixel configuration, compared to the previous generation, vivo X20Plus On the basis of the United States, to retain more details, hair clear after the enlargement of the face, the skin smooth and natural skin, really the hostess cute patting the most vividly. Overall slightly transparent, the color is also more bright, showing With the price of little and beautiful beauty effect, is probably the user choose one of the biggest reasons of vivo.

Portrait of the virtual model can play the role of the main body, so that the original chaotic background of the natural fuzzy principle.Although the model in the 2017 mobile phone market stage, almost most of the flagship are available, but can do the main matting precision Beauty is natural, the details are clear, the characters are fresh and elegant X20Plus Is the most disappointing a model.Viewed the proofs not only people sigh, self-timer is still the stronghold of vivo.

Popular point, vivo X20Plus Whether it is post-shooting or front self-timer, shot proofs more satisfactory, Compared to other flagship, vivo X20Plus With 2x12 million pixels, Independent DSP image optimization chip, OIS multi-axis optical anti-shake and take pictures pretty beauty algorithm, its advantage is not only look good pictures, more importantly, this generation Plus-level full screen mobile phone price 3498 yuan, cost-effective, relatively more conscience.
