Abstract
When an output image is observed, an image processing apparatus by which image observation can be performed always in a satisfactory state irrespective of its observation environment and a change of a human's visual characteristic is provided. In this image processing apparatus, a first output unit outputs the target image in a first gradation reproduction range, and a second output unit outputs the target image output by the first output unit in a second gradation reproduction range. At this time, a correction unit performs a correction process, i.e., gradation conversion process, to the target image output by the second output unit, on the basis of information concerning the environment for observing the output result of the target image by the second output unit.
