1. A computer-implemented method, comprising the steps of: determining at least one first matrix from a plurality of matrix entries, wherein first matrix entries of the plurality of matrix entries are determined as a function of at least a tone mapping parameter of a respective corresponding area within a high dynamic range input image; determining at least one second matrix from a plurality of second matrix entries, wherein each second matrix entry is determined as a function of the high dynamic range input image and of user input data; determining a third matrix as a function of the first matrix and the second matrix; and generating a tone-mapped image as a function of the high dynamic range input image and the third matrix.
