Summary device and method for extracting detected characteristic signal information and computer program The present invention relates to a device and method for extracting detected characteristic signal information. a data stream (26; 124a, 124b, 124c) derived from electromagnetic radiation (14) emitted or reflected by an object (12) is received. data stream (26) comprises a continuous or discrete characteristic signal (76; 132a, 132b, 132c) including physiological information (100) and a disturbance signal portion (94). the physiological information (100) is representative of at least one at least partially periodic vital sign (20; 156). the disturbance signal portion 94 is representative of at least one of a movement portion of the object and / or a non-indicative reflection portion. the characteristic signal (76; 132a, 132b, 132c) is transferred by converting at least three absolute components (92a, 92b, 92c) from the characteristic signal (76; 132a, 132b, 132c) related to the respective additive channels (74a, 74b). 74c) to at least two difference components (102; 142a, 142b) of the characteristic signal (76; 132a, 132b, 132c), wherein each of the at least two difference components (102; 142a, 142b) can be derived from a respective arithmetic transformation by considering at least two of the at least three absolute components (92a, 92b, 92c), wherein the arithmetic transformation comprises additive and subtractive coefficients. consequently, the disturbing signal portion (94) may be at least partially deleted in the transferred signal (32; 150). 1/1resumo dispositivo e método para a extração de informações de sinais característicos detectados e programa de computador a presente invenção refere-se a um dispositivo e um método para a extração de informações de sinais característicos detectados. um fluxo de dados (26; 124a, 124b, 124c) derivável de radiação eletromagnética (14) emitido ou refletido por um objeto (12) é recebido. o fluxo de dados (26) compreende um
