Beschreibung

Mit set_bg_esti_paramsset_bg_esti_paramsSetBgEstiParamsset_bg_esti_paramsSetBgEstiParamsSetBgEstiParams werden die Parameter im Datensatz verändert. Die übergebenen Parameter sind identisch mit denen für create_bg_esticreate_bg_estiCreateBgEsticreate_bg_estiCreateBgEstiCreateBgEsti (Erklärung siehe dort).

Das Bildformat kann jedoch nicht geändert werden, hierfür muss ein neuer Datensatz angelegt werden, bei dem das Initialisierungsbild das gewünschte Format hat.

Soll das Hintergrundbild komplett ausgetauscht werden, so muss update_bg_estiupdate_bg_estiUpdateBgEstiupdate_bg_estiUpdateBgEstiUpdateBgEsti verwendet werden. Es muss dann sowohl für das Eingabebild und auch für die Up-Date-Region das aktuelle Bild angegeben werden.

Achtung

Wenn GainModeGainModeGainModeGainModeGainModegainMode = 'frame'"frame""frame""frame""frame""frame" gewählt wurde, kann bei der Wahl von großen Werten für Gain1Gain1Gain1Gain1Gain1gain1 oder Gain2Gain2Gain2Gain2Gain2gain2 die Laufzeit sehr groß werden, da die Werte für die Gaintabelle mit einem eindimensionalen Optimierer (binäre Suche) bestimmt werden.
