Summary extraction device of physiological information of electromagnetic radiation emitted or reflected by a patient detected, method of extraction of physiological information of electromagnetic radiation detected.Emitted or reflected by a patient and computer program, the present invention relates to a device and method for extracting physiological information from electromagnetic radiation is detected, issued or reflected by a patient (10). A data stream (30) which can be derived from electromagnetic radiation emitted or reflected by a patient (10) is received.The data stream (30) includes a sequence (76 152) of samples of the signal (78a, 78B, 78c 154A, 154b, 154C) which indicate the desired movement of the patient and the movement disorder, in which the samples of signal (78a, 78B, 78c 154A, 154b,154C) represent at least one region of interest (84 164) and at least one region movement not indicative (86 166) and at least one region of interest (84 164) defined displays a movement pattern indicating at least partially periodic can be attributed at least u M physiological parameter (56), and a portion of the movement of the disorder.The sequence (76 152) of samples of the signal (78a, 78B, 78c 154A, 154b, 154C) is processed. A sequence (158) of the samples obtained with motion compensated (80 160A, 160b, 160C) at least partially compensated for unwanted total movement is obtained.At least one signal characteristic (90, 112) that indicates at least partially the movement pattern indicating at least partially periodic is obtained from the sequence (158) of the samples obtained with motion compensated (80 160A, 160b, 160C).The at least one signal characteristic (90, 112) is processed into account residual total movement that occurs in the samples obtained with motion compensated (80 160A, 160b, 160C), so as to generate at least one telltale sign improved (98 116). 1 \/ 2
