Claim 3:
4. An apparatus comprising:
one or more processors that execute a program stored in a memory to function as:
an image acquisition unit configured to acquire a training image and a correct answer image;
an execution unit configured to subject each of the training image and the correct answer image to a white balance correction or processing for changing a color gamut;
a generation unit configured to input the training image that have been subject to the white balance correction or the processing for changing the color gamut by the execution unit to a neural network to generate an output image based on output signal from the neural network;
an error acquisition unit configured to acquire an error between the correct answer image and the output image that have been subject to the white balance correction or the processing for changing the color gamut; and
an update unit configured to update parameters of the neural network based on the acquired error.
