The standard method for interfacing applications with video cameras on Windows. Available on Windows XP and Vista.
In QPix all above acquisition standards are organized into 3 acquisition protocols:
QPix provides the following acquisition features:
With a single call an application can digitize all pages from an automatic document feeder unit attached to a scanner, download all pictures from a digital camera, or acquire a series of frames from a video camera.
The application can provide one-click acquisition by hiding the device's user interface.
Image acquisition is done directly to disk, minimizing the application memory requirements.
