METHOD FOR CONVERTING INPUT IMAGE DATA INTO OUTPUT IMAGE DATA, IMAGE CONVERSION UNIT FOR CONVERTING INPUT IMAGE DATA INTO OUTPUT IMAGE DATA, IMAGE PROCESSING APPARATUS, DISPLAY DEVICE |
摘要 |
In a method, unit and display device the input image signal is split into a regional contrast signal (VRC) and a detail signal (VD), followed by stretching separately the dynamic ranges for both signals, wherein the dynamic range for the regional contrast signal is stretched with a higher stretch ratio than the dynamic range for the detail signal. Preferably the stretch ratio for the detail signal is near 1 or preferably 1. In preferred embodiment highlights are identified and for the highlights the dynamic range is stretched to an even higher degree than for the regional contrast signal. |
