SYSTEM AND METHOD FOR CONVERTING AN INPUT SIGNAL INTO AN OUTPUT SIGNAL

摘要

The present invention relates to a system and a method for processing data obtained from an input signal (24) comprising physiological information (54) representative of at least one at least partially periodic vital signal (18). The physiological information (54) is derivable from visible radiation (20) reflected by an object (16). The system comprises a detector means (28) for detecting at least one vital signature (50) in the input signal (24) and a converter means (30) for creating an output signal (34) by modifying the input signal (24) depending on the detected vital signature (50). The output signal (34) comprises an artificial signature (56) at least partially replacing a respective vital signature (50) of the at least one vital signature (50) of the input signal (24). In one embodiment the system further comprises a sensor means (22) for detecting visible electromagnetic radiation (20) within at least one particular wavelength range.
