METHOD AND DEVICE FOR ENCODING A HIGH-DYNAMIC RANGE IMAGE |
| 摘要 |
<p>The present invention generally relates to a method and device for encoding an image. The method comprises: - encoding (12) a backlight image determined (11) from the image; - obtaining (13) a residual image by dividing the image by a decoded version of the backlight image; - obtaining (16) a tone-mapped residual image by tone-mapping the residual image; - clipping (18) the residual image before encoding; and - encoding (19) the tone-mapped residual image.</p> |
