Abstract: A color chart and an illumination unevenness correcting chart are shot by a digital camera 1 under the same illumination, and color data on a first image obtained by shooting the color chart and color data on a second image obtained by shooting the illumination unevenness correcting chart are input to a color processing parameter editing apparatus 2 for generating a color processing condition used in color processing to be performed on an image shot by the digital camera 1. A correcting unit 204 corrects the color data on the first image using the color data on the second image. Target color data corresponding to the corrected color data on the first image is input. A parameter optimizing unit 205 generates a color processing condition for converting the corrected color data on the first image into the target color data.

Abstract: Color data which is obtained by capturing an image of a color chart by an image capturing apparatus under a first light source, and depends on the first light source is acquired. Target data which is based on colorimetry data of the color chart under a second light source, and depends on the second light source is acquired. The target data which depends on the second light source is converted into target data which depends on the first light source. A color processing parameter corresponding to the first light source is generated based on the color data which depends on the first light source and the target data which depends on the first light source.

Abstract: In order to obtain a highly accurate color processing condition, a user is allowed to easily adjust a weight for a patch image with poor reliability. Hence, a color processing apparatus inputs color data of a plurality of patches included in a color chart captured by an image sensing device. Patch images based on the color data are displayed on a monitor, and a user interface for inputting a user's instruction to adjust a weight value for each patch image is displayed on a monitor. A color processing condition of an image captured by the image sensing device is generated based on the weight value, the color data, and a target value of a color representation corresponding to each patch image.

Abstract: When saturation conversion is done by multiplying data by a saturation conversion parameter with a constant value regardless of image features, an image which can give good impression to the user cannot always be obtained. In this invention, an image is segmented into a predetermined number of blocks, and attributes are discriminated in units of blocks. Conversion characteristics are calculated on the basis of saturation conversion parameters of an image, which are set in correspondence with the discrimination result, and saturation is converted based on the calculated characteristics. In this way, appropriate saturation correction can be achieved in correspondence with the image attribute.

Abstract: It is difficult properly to perform correction processing such as white balance adjustment and exposure compensation for all types of images. This invention provides a way in which white balance adjustment and exposure compensation are performed in accordance with image features by considering the arrangements of pixel values in the highlighted and shadow areas of an image. Proper correction processing can therefore be performed for any types of images.
