Image processing apparatus, image processing method, storage medium, and program

An image processing method which performs a correction process to a target image output by a first output means having a first gradation reproduction range and then outputs the corrected target image by using a second output means having a second gradation reproduction range, comprising:

• a processing step of performing the correction process to the target image on the basis of observation environment information concerning an environment for observing at least an output result of the target image by the second output means.

An image processing method which is to perform a gradation conversion process between a first output means and a second output means respectively having different gradation reproduction ranges, comprising:

• a setting step of setting observation environment information representing an environment for observing an output of the second output means;
• and
• a gradation conversion processing step of obtaining an output gradation reproduction curve using the gradation conversion process on the basis of the observation environment information set in said setting step.

A computer-readable storage medium which stores-a program to execute an image processing method which is to perform a gradation conversion process between a first output means and a second output means respectively having different gradation reproduction ranges, said method comprising:

• a setting step of setting an environment for observing an output of the second output means and setting observation environment information concerning the set environment;
• and
• a gradation conversion processing step of obtaining an output gradation reproduction curve using the gradation conversion process on the basis of the observation environment information set in said setting step.

A computer-readable program which is to perform a gradation conversion process between a first output means and a second output means respectively having different gradation reproduction ranges, said program comprising:

• a code for setting an environment for observing an output of the second output means and setting observation environment information concerning the set environment;
• and
• a code for obtaining an output gradation reproduction curve using the gradation conversion process on the basis of the observation environment information set based on said setting code.
