Abstract: A method of correcting an image includes: inputting an input image and a correction parameter to a first neural network model; and obtaining an inference image from the first neural network model, the inference image corresponding to the correction parameter. The first neural network model is a model trained to minimize a difference between the inference image that is output after the input image and the correction parameter are input and a label image corresponding to the correction parameter. The label image is an image obtained by, when the correction parameter is applied to at least one image correction algorithm, correcting the input image by using the at least one image correction algorithm.
