Tone mapping method

摘要

Generating by a digital processing device, of a first digital image from a second digital image, by: for each pixel of the second image, determining a pixel luminance; dividing the interval ranging from the lowest to the highest luminance into a plurality of sub-intervals; and determining the value of at least one pixel of the first image by multiplying the value of a pixel of the second image by a gain determined by interpolation by taking into account the distance of the pixel luminance of the second image to the limits of the sub-interval containing this luminance.

1. A method, comprising:
generating, using a configured digital processing device, a first digital image from a second digital image, by:
determining a luminance value of each pixel of the second image;dividing a luminance interval ranging from a lowest determined luminance value to a highest determined luminance of the pixels of the second image into a plurality of sub-intervals; anddetermining a luminance value of at least one pixel of the first image by multiplying the determined luminance value of a pixel of the second image by a gain determined by interpolation based on a distance of the luminance value of the pixel of the second image to limits of a sub-interval containing the determined luminance value of the pixel of the second image.
