1. A method for image-based driver identification in a motor vehicle, comprising the acts of: recording at least one two-dimensional driver facial image using a camera; temporarily storing recorded driver facial images; comparing temporarily stored driver facial images to two-dimensional reference images of a possible driver from multiple possible drivers of the motor vehicle; and determining the current recording angle between the camera and the facial normal line of the driver by a device not otherwise used for image-based driver identification, wherein the recording of a driver facial image is triggered when the current recording angle reaches a specific preset value.
