Abstract
A method and device for image processing, and storage medium are provided. In the method, an initial image I is acquired; a pixel I(i) of the initial image is selected; a transfer function ƒ is applied to the pixel I(i) to acquire a transferred pixel Ĩ(i), and the transfer function ƒ is determined on the basis of at least the pixel information of the selected pixel; a predetermined tone-mapping function is applied to the transferred pixel Ĩ(i) to acquire a tone-mapped transferred pixel Ĩ'(i); an inverse of the transfer function ƒis applied to the tone-mapped transferred pixel Ĩ′(i) to acquire a tone-mapped final pixel I′(i). Herein, the steps are repeated for a plurality of pixels of the initial image I to generate a final image I′, and for each of the plurality pixels the same tone-mapping function is applied.
