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

摘要

A system and a method for processing data obtained from an input signal including physiological information representative of at least one at least partially periodic vital signal. The physiological information is derivable from visible radiation reflected by an object, such as a person. The system includes a detector for detecting at least one vital signature in the input signal and a converter for creating an output signal by modifying the input signal depending on the detected vital signature. The output signal includes an artificial signature at least partially replacing a respective vital signature of the at least one vital signature of the input signal. The system may further include a sensor for detecting visible electromagnetic radiation within at least one particular wavelength range.

1. A system for processing data obtained from an input signal comprising physiological information derivable from radiation reflected by a person, the physiological information being representative of at least one vital signal of the person, the system comprising:
a detector configured to detect at least one vital signature in the input signal, wherein the input signal comprises a continuous or discrete sequence of image frames related to a specific signal space, the at least one vital signature varying over time and corresponding to variations of the vital signal, and wherein the at least one vital signal is obtained from variations of skin color over time; a converter configured to create an output signal by modifying the input signal depending on the detected vital signature; and a switch for bypassing the detector and the converter, the switch being configured to receive the input signal and provide the input signal directly to an interface, wherein the output signal comprises an artificial signature at least partially replacing a respective vital signature portion of the at least one vital signature of the input signal.
