The present invention relates to a device and method for extracting information from remotely detected characteristic signals. A data stream 24 is obtained from the electromagnetic radiation 14 emitted or reflected by the object 12. The data stream 24 includes a sequence of frames 66, 70, 92, 94； 108, 110, 112, 122, 124； 164, 166, 168, and at least a portion of the frame includes a region of interest 56 belonging to the object 12. Representing frame sections 68, 72； 174, 180, 186. Region of interest 56 represents a continuous or discrete characteristic signal 136； 192 that includes physiological information 200 indicative of at least one at least partially periodic biological signal 20； 208. The sequence of frames 66, 70, 92, 94； 108, 110, 112, 122, 124； 164, 166, 168 further includes a disturbing signal portion that at least partially indicates undesirable object movement. The characteristic signal 136； 192 is derived from the frame 66, 70, 92, 94； 108, 110, 112, 122, 124； , 88, 98, 100, 102； 172, 176. Position shifts 74, 178 relative to the previous derived signal forms 78, 172 of the current derived signal forms 88, 98, 100, 102； 176 may be estimated. Considering the estimated position shifts 74, 178, the current frame section 72； 180, 186 may be determined. Thus, the region of interest 56 can be tracked to at least partially compensate for undesirable object motion. As a result, the disturbing signal portion can be at least partially compensated. Considering the determined sequence of frame sections 68, 72； 174, 180, 186, the characteristic signal from the sequence of frames 66, 70, 92, 94； 108, 110, 112, 122, 124； 164, 166, 168 136； 192 can be extracted.本発明は、遠隔検出された特性信号から情報を抽出するデバイス及び方法に関する。対象物１２によって発射又は反射される電磁放射１４からデータストリーム２４が得られる。データストリーム２４はフレーム６６，７０，９２，９４；１０８，１１０，１１２，１２２，１２４；１６４，１６６，１６８のシーケンスを含み、フレームの少なくとも一部は、対象物１２に帰属する関心領域５６を表すフレームセクション６８，７２；１７４，１８０，１８６を含む。関心領域５６は、少なくとも１つの少なくとも部分的に周期的な生体信号２０；２０８を示す生理学的情報２００を含む連続又は離散特性信号１３６；１９２を表す。フレーム６６，７０，９２，９４；１０８，１１０，１１２
