Samsung patents image upscaling that splits brightness and detail tasks

Samsung describes a method to make low-resolution images look sharper by using a neural network. The system separates the image's brightness information from its other details, processing them with different settings before combining them into a high-resolution picture.

Why it mattersThis could help phones and cameras produce clearer photos from low-light or zoomed-in shots without needing more hardware.

In the filing’s own words

An image processing method using a neural network model, and an electronic device are provided. The method may comprise: acquiring a low-resolution image; extracting, from the low-resolution image, luminance information through a luminance channel; acquiring a first feature vector on the basis of the luminance information by using the neural network model to which a first weight is applied; acquiring an output image from the first feature vector by using the neural network model to which a second weight is applied; and generating, on the basis of the output image, a high-resolution image with respect to the low-resolution image. The first weight and the second weight can be different.

What exactly they claim (claim 1)

1. A method for image processing using a neural network model, the method comprising: obtaining a low-resolution image; extracting luminance information from the low-resolution image through at least one luminance channel; based on the luminance information, obtaining a first feature vector, by using a first neural network model to which a first weight is applied; obtaining an output image corresponding to the first feature vector, by using a second neural network model to which a second weight is applied; and generating a high-resolution image for the low-resolution image, based on the output image, wherein a first connection structure of the first neural network model is the same as a second connection structure of the second neural network model.
