Enhancing is the correct term here, at least, in a technical context it is.
Image enhancement is defined as a process which aims to improve bad images so that they "look" better. Enhancement aims to make it look better to a human, and often but not always takes into account knowledge of the human visual system to get better looking results.
Image restoration is a defined as a process which aims to invert known degradation operations applied to image, such as pepper noise, scratches, or missing fragments of old photographs.
It's surprisingly to me how strongly you object to the word enhancement even though image processing textbooks are clear about the definition and have been using the word for decades. I think it shows some ignorance about how cameras and image processing works in modern devices.
