Abstract
An image processing method in which color-appearance matching of an output image to an input image is achieved regardless of ambient light. Color conversion is performed on image data representing an input image to fulfil color-appearance matching of an output image to be reproduced by an image, output device, to the input image. Color conversion is performed on the image data representing the input image obtained from the input device under a certain standard light source into image data dependent on a light source used for observation. The converted image data is further subjected to color conversion based on a reference white color determined when an observation is made. The resultant image data is output to the image output device.
