摘要：
The disclosure relates to image signal processing, encoded signals and fingerprinting. Lighting information, associated with image capture, is used to adapt a signal encoder to fingerprint generator. The encoder or generator can be adapted by applying different weightings to different color channels, the different weightings being associated with the lighting information.
