Classification: CPC G | IPC G

Claim 8:
9. An image display method for displaying image data on an image display unit, comprising:
a luminance acquisition step; and an image processing step, wherein
in the luminance acquisition step, a display luminance of the image display unit is acquired,
in the image processing step, a gradation characteristic of the image data to be displayed on the image display unit is set to a first gradation characteristic and simultaneously a luminance setting value of the image display unit is switched from a first luminance setting value to a second luminance setting value when a request to change the luminance setting value from the first luminance setting value to the second luminance setting value is accepted, and then the gradation characteristic of the image data to be displayed on the image display unit is switched 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 request is accepted, 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.
