Improvement in high-quality digital zoom segment

We have applied a super resolution video generation technology, which is based upon an AI model used to enhance the quality of the super high zoom section out of all the digital zoom applied sections.

Thanks to digital zoom’s lightweight computation, it provides a fairly high quality output despite the high processing speed. Hence, it is used as an essential method.

However, the quality of the magnified image drops in proportion to the zoom expansion, given the limitations of the digital zoom computation.

We have applied the AI model based super resolution video generation technology to overcome this sort of quality degradation.

First, the image input AI model preserves the original details of the image, and combines multiple frames of the image to get rid of noise to give us the final result.

The AI model suppresses any existing noise in the input image using the method it learned before.

And finally, the HDR takes care of (adjusts) the overall brightness of the image.

Comparing the improved results

You can refer to the images below and see how the AI model applied super resolution images have turned out in Z Flip 5.
