Method and apparatus with high-resolution image zooming

An electronic device comprising:

• an image sensor configured to capture a raw image;
• one or more processors;
• and
• a memory comprising one or more non-transitory storage media that store instructions that, when executed by the one or more processors, configures the one or more processors to:
• obtain the raw image from the image sensor;
• obtain an RGB image corresponding to the raw image;
• separate a luminance component and a chrominance component from the obtained RGB image;
• extract a first feature of the obtained RGB image, of which color information is enhanced, by applying the chrominance component to a first neural network;
• extract a second feature of the obtained RGB image, of which texture information is enhanced, by applying the raw image and the luminance component to a second neural network;
• and
• generate a zoom image corresponding to the obtained RGB image by upscaling the color information and the texture information based on the first feature or the second feature.
