Abstract
An image processing apparatus includes a unit configured to calculate a plurality of characteristic amounts from an input image, a unit configured to calculate a first multidimensional lookup table based on the characteristic amounts, a unit configured to calculate attribute information of a specific object from the input image, a unit configured to calculate a second multidimensional lookup table based on the attribute information, a unit configured to generate a control parameter from the input image, an interpolation unit configured to apply the first and second multidimensional lookup tables to the input image, and a control unit configured to control interpolation intensity of the second multidimensional lookup table using the control parameter.
