Abstract
A color matching control apparatus obtains a second image picked up by a second image pickup apparatus to include a color chart area, extracts pixel values of the color chart area included in a first image as first values, extracts pixel values of the color chart area in the second image as second values, calculates a dynamic range of the color chart area in the first image based on the first pixel values, sets a predetermined pixel in an area excluding the color chart area in the first image as at least one first singular point based on the dynamic range, extracts a pixel value of the at least one first singular point, sets at least one second singular point in the second image based on the at least one first point, extracts a pixel value of the at least one second singular point, and generates a color matching parameter.
