Claim 0:
1. An image display system configured to display image data, comprising:
an image display unit;
a luminance acquisition unit; and
an image processing unit, wherein
the image display unit is configured to display the image data,
the luminance acquisition unit is configured to acquire a display luminance of the image display unit,
the image processing unit is configured to set a gradation characteristic of the image data to be displayed on the image display unit to a first gradation characteristic and simultaneously switch a luminance setting value from a first luminance setting value to a second luminance setting value when the image display system accepts a request to change the luminance setting value of the image display unit from the first luminance setting value to the second luminance setting value, and then switch the gradation characteristic of the image data to be displayed on the image display unit to a second gradation characteristic,
the first gradation characteristic associates a gradation value with a first target luminance,
the first target luminance is acquired based on the display luminance in a state of displaying the image data at the first luminance setting value before the image display system accepts the request, and the first target luminance is a target luminance estimated to display the image data at the display luminance in a state where the image display unit sets the second luminance setting value as the luminance setting value,
the second gradation characteristic associates the gradation value with a second target luminance, and
the second target luminance is acquired based on the display luminance in a state of displaying the image data of the first gradation characteristic with the second luminance setting value.
