The technology that enhances the resolution of digital images is known as image upscaling or super-resolution. Advanced algorithms, often powered by machine learning, allow for the enlargement of images while preserving or enhancing detail and clarity. Techniques like deep learning utilize convolutional neural networks to learn from high-resolution image datasets, enabling them to generate clearer images from low-resolution sources. This technology is particularly valuable in applications like photography, video production, and gaming, where superior image quality significantly impacts user experience.
