Ich benutze ein Dinolite -Mikroskop, um Teile zu steuern. Aber nach stundenlangem Gebrauch wird das Bild beschädigt. Ich verwende Pyside6 mit offenem Lebenslauf
Sie finden das Bild und meinen Code hier. Die Bilder sind in Farbe, aber für den Versuch korrigiere ich die Helligkeit nicht. JPG " /> < /p>

Wenn ich ein Bild speichern möchte, mache ich < /p>
 path_select = os.path.join(basedir, 'test'+str(0)+'.jpg')
self.array[0].save(path_select)
shutil.copy(path_select, path_image)

Ich finde diesen Fehlerursprung nicht.
