Abstract
An output device is set to a first state in which a value of a first characteristic of the output device is set to a first value. Pixel adjustment values for plural gray levels are set to first pixel adjustment values in response to the output device being set to the first state. The value of the first characteristic is changed from the first value to a second value to set the output device to a second state. The pixel adjustment values for the plural gray levels are updated to second pixel adjustment values in response to the output device being set to the second state. The second pixel adjustment values are derived based on the second value of the first characteristic. Pixel values applied to a plurality of pixels of the output device are corrected based on the second pixel adjustment values.
