Abstract
An image processing apparatus which is capable of properly performing tone correction without damaging the atmosphere of an image in shooting. Based on a luminance histogram for photographed data, an input lower limit and an input upper limit of luminance values for use in developing the photographed data are determined. Based on at least one of the input lower limit and the input upper limit, a reference level of a gamma curve for use in carrying out gamma correction on the photographed data is calculated. Gamma correction on the photographed data is performed using the input lower limit and the input upper limit and the gamma curve corresponding to the reference level.
