发明名称 VERFAHREN UND SYSTEM ZUR DIGITALEN ABBILDUNG ZUR EINSTELLUNG DER BELICHTUNG UND ENTSPRECHENDE EINRICHTUNG
摘要 The invention relates to a method in digital imaging for adjusting exposure, in which one or more exposure parameters (ET, AG) of a camera device are adjusted in connection with imaging. In the method, a histogram formed from a raw image frame (12) is analysed, from which one or more special values (Rhigh, Rlow) are specified and which compared with a target level (Htgt, Ltgt) set for them, and, if a special value (Rhigh, Rlow) differs from the target level (Htgt, Ltgt), the exposure parameters (ET, AG) are adjusted to achieve the target level (Htgt, Ltgt).
