Disclosed is a method for controlling an in-vehicle monitoring system, the method comprising: monitoring a driver of the vehicle using an image capture system comprising one or more image capture devices (e.g. cameras) 210; determining that the driver will be obscured from the image capture system by an obscuration 212 and create an obscuration event; generating an obscuration signal in dependence on said determination; and in dependence on an obscuration signal, altering the viewpoint of the image capture system so as to reduce the time during which the driver is obscured from the image capture system by the obscuration. Altering the viewpoint may be achieved my moving the image capture device (fig. 5) or by switching from a first image capture device 210 to a second image capture device 214 (fig. 6). The obscuration signal may be generated in response to a detected obstruction (e.g. driver’s hand, steering wheel spoke etc.). Alternatively the system may predict that an obscuration event is going to occur by analyzing vehicle or road parameters and, for instance, establishing that the steering wheel will be turned. The analysis may also account for past driver behavior, e.g. likely hand position.
