METHOD AND DEVICE FOR PROCESSING VIDEO DATA FOR DISPLAY ON A DISPLAY DEVICE

摘要

The visible pattern of classical matrix dithering in case of applications with moving pictures and static pictures shall be suppressed more effectively. Therefore, it is proposed to change a dithering pattern in the dithering block (12) nonperiodically. This can be effected by a random generator (13) which may be activated by a motion detector (14). The motion detector (14) enables to individually alternate the dithering function depending on moving or static pictures.
