1. A method of generating a low-light image, comprising:
obtaining a raw image captured by a sensor;
removing an amount of first illumination from the raw image;
applying a low exposure condition to the raw image having the amount of first illumination removed;
obtaining a low-light image by applying an amount of second illumination less than the amount of first illumination to the raw image having the applied low exposure condition;
obtaining a noisy image by applying an amount of noise to the low-light image having the applied amount of second illumination; and
training a neural network model for denoising an image based on the low-light image and the noisy image.
