It is a fact, everything enters through the eyes: the images of the movies we love, the social networks that we consult at all times, the photos of our loved ones. Thus, MediaTek has invested millions of dollars, and years of research, into two technologies that not only protect your eyes, they also extend battery life.
Is MiraVision and Intelligent Display Sync 3.0. Technological initiatives that are not only based on state-of-the-art technology, but also on years of experience. Not for nothing, Mediatek chips are currently used in more than 2.000 million televisions worldwide.
This visual management experience is brought to all technology-enabled devices. MediaTek, especially mobile phones, devices that users typically use more than 3 hours per day. But on mobile platforms there is an additional challenge to image quality, it is also offering the best battery performance.
MiraVision, more than a technology
MediaTek's response to visual challenges comprises several initiatives bundled under one name: Miravision. Therefore, it is correct to say that MiraVision is not a technology, it is a set of several of them that include names like Bluelight Defender; Ultra Dimming; Chameleon display; Smart Screen Display; HDR Composer and AI-PQ, among others.
“Miravisión is a collection of video processing technologies that are used to improve the image quality of screens. It has a huge benefit for consumers because it improves the image, the visual experience of the user and the visual comfort” said YR Chen, director of multimedia technology OOCTO of MediaTek.
Although talking about images seems simple, the reality is something else, since they include components such as color, brightness, contrast, sharpness, and dynamic range, among other factors. And many of these variables change throughout the day, so displays must adapt to these fickle environments.
This adaptation to change is achieved thanks to the power of Artificial Intelligence and the use of algorithms such as those used by MediaTek's AI-PQ technology. Originating from the television market, AI-PG (Artificial Intelligence Picture Quality) technology can read the type of content in each scene to change the parameters of images for better quality.
But these quality improvements must be made while simultaneously optimizing power consumption, which gave rise to SmartScreen Display technology. This is an initiative that detects the lighting conditions of the environment and compares them with the content displayed on the screens to generate a balance between both fronts.
However few technologies are as relevant as the BluLight Defender, a solution designed to protect the eyes by reducing the intensity of blue light, generated by screens, without affecting color quality. This technology is hardware based and does not produce the ugly yellow/reddish effect generated by other software based solutions.
As we mentioned before, the reproduction of images is somewhat complex and for this Miravision includes even more technologies such as Ultra dimming and HDR Composer. The latter is a system capable of converting content from the SDR (Standard Dynamic Range) format to the HDR (High Dynamic Range) standard.
Let's remember that SDR, being a format that dates back to the 2014th century, has less contrast, color gamut, and image quality than its successor, HDR, which hit the market in XNUMX, bringing a capacity for detail never seen on traditional television. .
Miravision has gone one step further and has created a technology capable of analyzing, frame by frame, and section by section, SDR videos to convert them, in real time, into a higher format. Miravisión even supports the new HDR10+ version to offer more contrast and image quality.
For its part, Ultra dimming is a technology that allows reading, clearly and comfortably, in dark environments, protecting eyes and improving equipment performance. Chameleon display is another member of Miravision and is a technology capable of monitoring the environment to facilitate the reading of letters and images.
Intelligent Display Sync 3.0
The frequency with which the images are generated, on the screens, usually provides a sense of greater fluidity, such as the Xiaomi 12T that comes with a refresh rate of 120Hz, that is, it presents a repetition of 120 frames of images per second. that shines in the use of applications, videos, games, etc.
However, not all content needs that rendering speed. Think, for example, of reading electronic books and documents where the frequency of images is the least of it. With an additional incentive: the lower the frequency, the lower the energy consumption.
To generate an adequate response to this changing environment, Miravision designed Intelligent Display Sync 3.0, an intelligent technology, capable of detecting, by itself, the kind of content that is displayed on the screen and thus determining the most appropriate refresh rate. for each case.
