High dynamic range images are used to store and transfer an extended range of intensities to render them on a display. To reproduce such images on displays with a lower range, tone mapping algorithms are used. The tone mapping algorithm described in this paper is a modification of the globally optimized linear windowed tone mapping algorithm. This modification is based on the human vision system model; it makes it possible to improve the results produced by the algorithm and replaces the nonintuitive parameters with a number of intuitively clear ones the variation of which in a high range does not visually distort the image. The high quality of the results produced by the algorithm is confirmed by the high TMQI index and the low value of the DRIM metric.
