摘要： The disclosure relates to a method comprising:
- obtaining input elements;
- mapping the input elements to output elements according to a Look-Up Table (LUT) based on a mathematical transform;
- modifying the mathematical transform and/or the Look Up Table before the mapping.
The disclosure relates for example to a method comprising:
obtaining input colors of a visual content;
- mapping the input colors to output colors according to a Look-Up Table (LUT) based on a color transform;
- modifying the color transform and/or the Look Up Table before the mapping.
It also relates to corresponding device, system, computer readable program product and storage medium.

摘要： The disclosure relates to a method comprising:
- obtaining an audio and video input content complying with a first format providing a representation of data in a first range of possible values;
- applying a first format modification to the input content, providing an output content complying with a second format providing a representation of data in a second range of possible values;
- associating to the output content a first kind of format modification representative of range operations performed between values of the first and second ranges.
The disclosure also relates to a method comprising:
- obtaining an audio and video input content complying with an input format providing a representation of data in an input range of values,
- obtaining information associated with the input content and comprising at least one first kind of format modification adapted to represent range operations performed between values of a first range and values of a second range by a first format modification;
- determining whether to apply a second format modification to the input content by taking account of the first kind of format modification and, when a second format modification is needed, determining a kind of the second format modification by taking account of the first kind of format modification.
It also relates to corresponding signal, devices, electronic assembly, system, computer readable program products and storage media.

摘要： Instead of using a single LUT to model a processing function, it is proposed to use another smaller LUT, i.e. an iterative LUT, such that, when applied at least two times in succession to data to process, the same processing function is modeled with at least the same accuracy. A specific way to compute this iterative LUT is given. Specific applications are given in the field of color processing.
Advantage: modeling is more accurate and/or less bins are needed to model complex functions.
