METHOD OF DISPLAYING A LOW DYNAMIC RANGE IMAGE IN A HIGH DYNAMIC RANGE

摘要

A method of increasing the dynamic range of an image comprising a plurality of pixels each having a luminance value within a first luminance range is provided. The method includes determining a background luminance value for each pixel of the image and determining a minimum and a maximum of the background luminance values. A conversion factor is then determined for each pixel of the image based on the minimum and maximum of the background luminance values. The image is converted from the first luminance dynamic range to a second luminance dynamic range by multiplying the luminance value of each pixel of the image by its conversion factor.
