Abstract:
A method for synchronizing a camera that has an image sensor with a projector that can generate a synchronization signal which corresponds to the projector frame rate. The projector is operated with a frame rate (F2), and the camera is operated with a frame rate (F1). A blanking interval is formed between individual images, and the synchronization signal of the projector is provided for controlling the camera. In order to match a phase (P1) of the frame rate (F1) of the camera to a phase (P2) of the frame rate (F2) of the projector and/or in order to match the frame rate (F1) of the camera to the frame rate (F2) of the projector, one or more blanking intervals between the individual images of the camera are varied dependent on the synchronization signal of the projector. For this purpose, a control circuit carries out a comparison between the phase (P1) of the frame rate (F1) of the camera and the phase (P2) of the frame rate (F2) of the projector and/or between the frame rate (F1) of the camera and the frame rate (F2) of the projector, wherein the trigger input of the image sensor is not activated for the matching process.
