Detailed Description

Tato trida reprezentuje kameru ziskavajici snimky z prvni fyzicke kamery umistene v systemu a umoznujici pristup pres DirectShow.

Trida plne respektuje pravidla bazove tridy TCameraAbstract a proto by manipulace s vytvorenym objektem mela probihat pouze pres bazovou tridu (rozhrani).
