Abstract
An information-processing apparatus includes: a first acquisition unit configured to acquire gradation characteristic information which relates to a gradation characteristic; a second acquisition unit configured to acquire axial characteristic information which relates to an axial characteristic including a distribution, on an axis, of graduations corresponding to brightness-related values related to brightness of input image data; and a generation unit configured to generate, based on the input image data, the gradation characteristic information, and the axial characteristic information, distribution information indicating a distribution of the brightness-related value of the input image data using the axis according to the axial characteristic information.
Claims16
An information-processing apparatus comprising:
- a first acquisition unit configured to acquire gradation characteristic information which is information related to a gradation characteristic;
- a second acquisition unit configured to acquire axial characteristic information which is information related to an axial characteristic including a distribution, on an axis, of graduations corresponding to brightness-related values related to brightness of input image data;
- and
- a generation unit configured to generate, based on the input image data, the gradation characteristic information, and the axial characteristic information, distribution information indicating a distribution of the brightness-related value of the input image data using the axis according to the axial characteristic information.
An information-processing method comprising:
- acquiring gradation characteristic information which is information related to a gradation characteristic;
- acquiring axial characteristic information which is information related to an axial characteristic including a distribution, on an axis, of graduations corresponding to brightness-related values related to brightness of input image data;
- and
- generating, based on the input image data, the gradation characteristic information, and the axial characteristic information, distribution information indicating a distribution of the brightness-related value of the input image data using the axis according to the axial characteristic information.
Anon-transitory computer readable medium that stores a program, wherein
- the program causes a computer to execute:
- acquiring gradation characteristic information which is information related to a gradation characteristic;
- acquiring axial characteristic information which is information related to an axial characteristic including a distribution, on an axis, of graduations corresponding to brightness-related values related to brightness of input image data;
- and
- generating, based on the input image data, the gradation characteristic information, and the axial characteristic information, distribution information indicating a distribution of the brightness-related value of the input image data using the axis according to the axial characteristic information.
