Zusammenfassung:To provide an image processing apparatus, an image processing method, and a program that can perform color calibration for image formation of a color image corresponding to different recording media without using a spectroscopic colorimeter.SOLUTION: An image processing apparatus comprises: an acquisition unit that acquires read values obtained by a reading unit for a paper white part of a recording medium and a plurality of gradation patterns of process colors formed on the recording medium; a prediction unit that predicts a device-independent absolute color value based on the read value for the paper white part of the recording medium; a conversion unit that converts the read values for the plurality of gradation patterns into device-independent color values; and a correction unit that corrects the color values converted by the conversion unit into device-independent absolute colors based on the absolute color value predicted by the prediction unit.SELECTED DRAWING: Figure 12 【課題】分光測色計を用いずに異なる記録媒体に対応したカラー画像の画像形成に対する色校正を行うことができる画像処理装置、画像処理方法およびプログラムを提供する。【解決手段】記録媒体の紙白部、および記録媒体上に形成されたプロセスカラーの複数の階調パターンについての読取部による読取値を取得する取得部と、記録媒体の紙白部の読取値に基づいて、デバイス非依存の絶対色値を予測する予測部と、複数の階調パターンの読取値をデバイス非依存の色値に変換する変換部と、変換部により変換された色値を、予測部により予測された絶対色値に基づいてデバイス非依存の絶対色に補正する補正部と、を備える。【選択図】図12
