A device driver for an image capturing device. The device driver detects and monitors characteristics of the image capturing device as well as that of a host machine processing image data coming from the device. Based on the detected and monitored characteristics, the device driver coordinates image processing on the host machine by configuring on-the-fly a plurality of functional modules supported by the host machine for performing various image processing tasks. When monitored characteristics warrants a different configuration of functional modules, the device driver on-the-fly reconfigures the functional modules.
