DIGITAL IMAGE TONE REMAPPING METHOD AND APPARATUS |
摘要 |
A digital image tone remapping method is disclosed. The method includes computing an average luminance value of a digital image; generating a preliminary tone mapping function according to the average luminance value; generating a luminance statistic of the digital image; determining new remapped values for a plurality of skeleton luminance values according to the preliminary tone mapping function and the luminance statistic; generating a final tone mapping function according to the new remapped values and the plurality of skeleton luminance values; and remapping the digital image through the final tone mapping function. The present invention also discloses an apparatus performing the method.
