1. An image processing apparatus, comprising:
a processor; and
a memory, including instructions stored thereon, which, when executed by the processor cause the apparatus to:
acquire a probability distribution of a color in a teacher image group;
correct a variance in a probability distribution for hue in the teacher image group to a larger variance than for luminance;
generate, as an artificial teacher image, an image having a color sampled based on the corrected probability distribution;
perform learning of a learning model for performing a demosaicking inference, by using the artificial teacher image,
wherein the artificial teacher image has one or more connected regions having the same pixel value as a value sampled from the corrected probability distribution.
