ABSTRACT:
In a set of non-reference gamma characteristics corresponding to a density adjustment value, a first region has first characteristics for converting input values to the maximum output value. A second region has second characteristics for converting input values to the minimum output value. A third region defined between the first and second regions has third characteristics for converting input values to intermediate output values. The third characteristics defines a monotonous curve that changes monotonously with respect to change in the amount of the input value. The amount of at least one of the first region and the second region is different from the amount of the corresponding at least one of the first reference region and the second reference region of the reference gamma characteristics by a degree dependent on each density adjustment value.
