What is super-resolution algorithm?​


According to professional explanations, super-resolution imaging (SR) is a type of technology that enhances (increases) the resolution of an imaging system. In optical SR, the diffraction limit of the system is surpassed, while in geometric SR the resolution of digital imaging sensors is increased. For TVs, super-resolution imaging technology can make the TV display clearer.

Why TV need super-resolution algorithm?​


Why do we need super-resolution algorithm for TV? Many people will be curious, what is the difference between a TV and a monitor?

What the monitor does is to restore the signal point-to-point, it is really just displaying. The TV has an additional image processing chip. The super-resolution algorithm in this chip is responsible for supplementing the low-definition picture to the high-definition.

It is because of this algorithm that even when playing 4K content, an 8K TV will be clearer than a 4K TV.

Didn't 4K TVs have super-resolution algorithms in the past?

Yes, but the reason we don't care too much is because it's very counter-intuitive. If the super-resolution algorithm turns low-definition into high-definition, it should be the more stubborn the source, the more obvious the effect, right?

But on the contrary, the clearer the picture and the more correct information on the picture, the better the super-resolution algorithm will be.

So why do you want to make 8K TVs early when 8K film sources have not been popularized to this day?

Because the increase in resolution is only superficial, the real improvement is the algorithm. This phenomenon is not only reflected in the resolution, but also in the color gamut.

Mid-to-high-end TVs can easily cover more than 90% of the P3 color gamut, far exceeding the color gamut of the film source itself. But because of the existence of the color gamut mapping algorithm, the TV will automatically pull the sRGB source into the wider P3 color gamut.

Why use a 60Hz or even a 120Hz screen when 24-frame TV shows are the mainstay?

Because the motion compensation algorithm will make up 24 frames to 120 frames. The existence of the image quality algorithm is a less perfect way, but this is precisely the core competitiveness of high-end TVs. The solution is how to play the same source and bring about a more "real" effect.
