摘要： An image formed from pixels each having components defining a color is processed to implement an increase in the saturation of the image depending on a gain applied by a transfer function depending on the components of the color of each pixel. The gain of the transfer function is parameterized using at least one control parameter respectively dedicated to at least one type of reference image content. The value of the at least one control parameter is calculated depending on the actual content of the image by implementing calculations including determining colorimetric statistics of the pixels of the image and processing the statistics in accordance with at least one processing model respectively associated with the at least one type of reference image content.
