METHOD OF SIGNAL RECONSTRUCTION, IMAGING DEVICE AND COMPUTER PROGRAM PRODUCT |
摘要 |
<p>A dynamic range control is of particular interest for scenes with a high contrast between dark and bright parts. Both parts may contain detailed information, although in most cases the dark part is given priority during signal reconstruction processing. In such a case the dark parts of a scene are amplified to a level that offers sufficient visible details, whereas in most prior art cases the bright parts may exceed the maximum permissible signal amplitude and will then be clipped. Such a measure will, in most cases, cause the loss of all details above and beyond the maximum permissible signal amplitude level. It is proposed that in particular the bright parts of a scene are compressed by means of a non-linear transfer function such that the specific demands of an input signal are taken into account.</p> |
