Understanding the 10bit Color
In the past year, although there are many cell phone manufacturers have begun to make efforts on the screen to make up for the parameters. But in addition to the widely known resolution, refresh rate, color depth as a slightly cold parameter has not been paid attention to.
The recently released Honor V40 mobile phone, in addition to high resolution and high refresh rate, 10bit color depth as an extremely important selling point. So what exactly does 10bit mean? What does it do for our daily use of cell phones? I believe that after reading this article today, we will all have some preliminary understanding.
Before introducing the improvement of 10bit color depth, first of all, we have to understand what is 10bit color depth. As we all know, the colors displayed by most of the electronic devices around us are based on the combination of RGB primary colors. And we often say 8bit color depth screen devices, their R, G, B three color channels can display based on 28 or 256-bit color scale, so this kind of equipment can display 2563 colors, that is, 16.77 million kinds of colors.
Therefore, as the name implies, the 10bit color depth is improved by up to 4 times in a single color channel compared to 8bit. The single-channel from 256-bit color scale to as high as a 1024-bit color scale, without looking at the physical picture to be able to imagine, the color transition will certainly be more delicate. The three channels count together, the total number of colors from 16.67 million colors, a direct leap to 1.07 billion, the display image will be closer to the natural look and feel.
If there is no comparison, in fact, in most scenes of life, it is difficult for us to intuitively feel the difference between 8bit and 10bit. But once you get used to 10bit, you can feel the obvious difference when you see the content displayed in 8bit.
Like the most obvious place where the difference in color depth is reflected, there is no more obvious than the change in pure color. In the monitor test, we often use the gradient of the grayscale to measure how much color depth of the monitor. 10bit content will be adaptive to display as a subtle change, while the lower 8bit content or even 6bit content, will show a clear distribution of color bands.
Putting the usage scenario into the phone, the enhancement it brings naturally is the perfect support for 10bit material with more delicate colors. Like many photographers, when taking photos and videos, they choose 10bit or even 12bit color depth for the original material. To leave more space for post-creation, then want to view these materials correctly, a 10bit color depth display device is essential. Like cell phones, as one of the most convenient and commonly used electronic devices around, support 10bit color depth display is very important for this creative work.
On the other hand, in addition to photography, 10bit is naturally the most important thing for ordinary people is the improvement of color when watching movies and brushing dramas. Although 10bit is not yet popular in domestic streaming media, for users who love to download and watch dramas, many foreign movies and TV works in recent years can easily find 4K HDR 10bit or even higher specification resources. Using the 10bit screen of the Honor V40, you can get a more detailed picture display, like the lightsaber in the picture, the halo around it can be spread out very naturally, without obvious light bands.
Besides, under the same specification, 10bit film and TV resources have more advantages than 8bit resources in terms of file size and bit rate. This is because 10bit has a more accurate color display without having to worry about color blocks, let alone using techniques such as color progression to eliminate them and bring in a lot of redundant information. Therefore, 10bit re-encoding can achieve high image quality with a lower bit rate and higher compression rate, which is also a great boon to the collection. To reflect its value, hardware devices that support a 10bit display are naturally essential.
I believe that after reading this, you can have a general understanding of the importance and enhancement of 10bit. If you want to have a 10bit HDR on your cell phone, a hardware device that supports a 10bit display is essential. But at present, there are not many phones on the market that support 10bit display, and the newly released Honor V40 happens to be one of them, and it is also the most affordable choice in terms of price.
Honor V40 Display Specifications in details
As for the screen, Honor V40 also ushered in a new upgrade, equipped with a 6.72-inch 80)° super curved OLED waterfall screen, with a screen ratio of up to 93.24%. What’s more, this is also the industry’s leading 1 billion color retina-level super-sensitive screen, not only the pixel density to retina-level 440 PPI but also support 1 billion color original color display, color depth than the traditional 16.7 million colors 64 times more delicate degree, color transition more delicate and smooth, bringing super-sensitive visual experience.
Honor V40 screen support P3 wide color gamut display, richer colors, more realistic reproduction, but also the first introduction of the color management system, regardless of pictures, videos, App using sRGB, P3 or Rec.2020 color-coding format, can be accurately converted to P3 color gamut, on the screen to present a rich color and detail reproduction. And, every piece of Honor V40 screen is calibrated by the production line color temperature out of the field to ensure that every user has the same accurate and perfect color experience. At the same time, Honor V40 screen refresh rate of up to 120Hz, in browsing the web and playing games, you can see less trailing shadow smoother display effect, so that consumers intuitively feel the quality screen detail color through the visual.
Through the professional color temperature sensor and ambient light sensor, Honor V40 also integrated with the ambient light management system, can feel the external environment in real-time warm and cold light, light and dark changes, according to the color temperature in different light dynamic color adjustment, to achieve automatic color temperature calibration, 4096 levels of screen brightness adjustment, so that the screen always maintain the best visual perception. With this, Honor V40 also got the first TÜV Rheinland Global Eye Protection 2.0 certification.
The V40 has a built-in super-sensitive touch engine that enables chip-level touch response through AI algorithms, making the 120Hz screen refresh rate and 300Hz touch sampling rate perfect for faster screen response, helping gamers to be one step ahead in the game. The super-sensitive touch engine also learns from massive data and dynamically adjusts the anti-mistake touch area and mistake-touch improvement scheme according to different scenarios such as gaming, typing, and audio and video, effectively avoiding the edge mistake-touch problem of super-curved screens.
Honor V40 Camera Experience In Night Shooting
Honor V40 rear camera this time ushered in a new upgrade, equipped with a 50-megapixel ultra-sensitive image system, supplemented by 8-megapixel ultra-wide angle + 2-megapixel macro camera, but also specially equipped with a laser focus module, focusing speed more quickly, can effectively improve the capturing rate.
Among them, this 50-megapixel super-sensitive main camera is the most important of the entire image system, upgraded 1/1.56-inch flagship super large bottom sensor, compared to the previous generation of “super-large cup” Honor V30 Pro 1/1.7-inch area increased by 25%. The single-pixel area is 1.0um, which also supports 4-in-1 equivalent 2.0um, far exceeding the 1.7um of Apple’s flagship iPhone 12 Pro series.
As we all know, in the photography world has been circulating a famous saying is “the bottom of a large level of pressure”, mainly because the larger the sensor, the stronger the ability to sense light, in the same environment, the large bottom sensor can receive more light, to get a brighter picture, but also to have a higher dynamic range.
With the support of a 1/1.56-inch large-bottom sensor, the Honor V40 can get greater light intake, greater dynamic range, and better noise control when taking pictures, so that it can achieve brighter, less noisy, and clearer pictures than other phones in the same environment.
Through the above figure can see the advantages of the Honor V40 large bottom sensor, the picture in the framing frame and the human eye to capture the picture is basically the same, and the final shot out of the picture compared to the real picture of the brightness completely upgraded and so on a few notches, its ability to perceive the light far more than the human eye effect, just through a little weak light can accurately restore the details of the picture, greatly meet the needs of the user night shooting.
Besides, the Honor V40’s excellent night shooting ability is also thanks to the RYYB array, which can bring 40% higher than the ordinary sensor light intake, which is also the Honor V40 to enhance the night shooting effect of the secret weapon.
Specifically, the general cell phone image sensor is used Bayer array (RGGB), through 1 red (R) 2 green (G) 1 blue (B) arrangement of the collected light signal into color information, to combine into a complete picture presented, but this process will inevitably lose a lot of light, resulting in very low picture brightness.
The RYYB array is by replacing the two green pixels (G) with yellow pixels (Y), also in disguise to increase the amount of red light in the three primary colors (yellow = red + green), can effectively reduce the RGGB in the process of color filtering to bring light into the amount of light loss, and finally through the algorithm to support the conversion to a brighter picture, the overall compared to ordinary cameras can improve the amount of light into 40%.
Thanks to the 50-megapixel RYYB sensor, the Honor V40 night shooting the whole picture of noise control is very good, on the picture may obviously feel, the exterior wall decorative lights of every light and shadow details are clearly visible, light and dark junction lines are clear, no paste into a piece of the situation, while the highlights also did not appear overexposed situation, the letters of the distant LED light signs are clearly visible, sharp edges.
It is worth noting that the color reproduction in the sample images is also very accurate, which also fully reflects the Honor RYYB sensor’s excellent tuning, optimization effect.
Through the above, we all know that RYYB is indirectly improve the light reception capacity by increasing the yellow pixels, but it brings higher light at the same time, will also increase the number of yellow pixels on the screen, resulting in the final picture effect color difference, the overall picture yellowish, which is also the most difficult breakthrough using the RYYB array.
But Honor, with excellent R&D capabilities, developed a powerful set of optimization algorithms, while with the excellent AI performance of the Dimensity 1000+ processor, can improve the brightness while greatly restoring the true color.
Besides, the Honor V40 also through the Dimensity 1000+ excellent AI performance and honor’s soft and hard synergy tuning capabilities, with the laser focus module can quickly focus, handheld super night scene multi-functional, compared to the ordinary mode can present more dark details, even the details of the first-floor windows are clearly visible, the overall brightness is again improved.
Overall, Honor V40 is through the powerful hardware and excellent software research and development strength of the joint support, and finally presented an excellent night shooting ability of the super-sensitive image system.
Besides, Honor has the full-link imaging technology strength, from ISP, NPU arithmetic, leading RAW domain AI algorithm, to the lens to the sensor, with a large number of technical reserves and innovation, from the entire chain to open up the imaging technology, so that the image strength continues to improve. Furthermore, the Honor V40 also supports 4K time-lapse HDR photography, 1920fps super slow motion, super portrait night view, and dual-view front and rear video, giving consumers an unprecedented image experience.
