    摘要: When, for example, MAC (multiplexed analog components) signals (inter alia C-MAC or D2-MAC signals) are recorded directly on a video recorder and no special steps are taken, information will be lost as a result of the change-over from recording by one write head to recording by another write head. The relevant signals to be recorded include a sequence of lines with a first signal block containing a line-synchronizing signal and at least one additional signal, and a second signal block containing the chrominance luminance information of the video signal. Specific first signal blocks or at least the additional signals of these first signal blocks are accommodated in a second signal block of a non-relevant video line and are subsequently recorded on the record carrier. After the relevant second signal block has been read from the record carrier, the relevant first signal blocks, or at least the additional signals of these first signal blocks, are extracted from the second signal block and re-inserted into the data stream of first signal blocks at their original locations. The relevant first signal blocks may be those first signal blocks during which the heads are switched or may be other (subsequent, with respect to time) first signal blocks which can no longer be inserted into the data stream of the first signal blocks because these first signal blocks, during which head switching is effected, have been repeated earlier in the data stream.

    摘要: The present invention relates to a device and a method for extracting information from detected characteristic signals. A data stream (26; 124a, 124b, 124c) derivable from electromagnetic radiation (14) emitted or reflected by an object (12) is received. The data stream (26) comprises a continuous or discrete characteristic signal (76; 32a, 132b, 132c) including physiological information (100) and a disturbing signal portion 5 (94). The physiological information (100) is representative of at least one at least partially periodic vital signal (20; 156). The disturbing signal portion (94) is representative of at least one of an object motion portion 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) of the characteristic signal (76; 132a, 132b, 132c) related to respective 10 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 through a respective arithmetic transformation 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 1 disturbing signal portion (94) can beat least partially suppressed in the transferred signal (32; 50).

    摘要: Image data processing is facilitated. According to an example embodiment, image data is processed using photometric similarity and, where appropriate, a classification of sample pixels for the image data.

The method further includes obtaining at least one value of at least one variable determining influences of at least components of respective second signals (18-20;55-57) on the output signal (31) when the signals corresponding to the second signals (18-20;55-57) are captured and the transformation (22,26,30) is applied, by at least one of: (i) analyzing at least one of the second signals (18-20;55-57), an output signal (31) obtained by applying the transformation (22,26,30) to the second signals (18-20) and a first signal (42;50a-n) derived from the output signal (31) and using the analysis to select at least one value of at least one parameter (54) corresponding to a respective one of the variables; and (ii) calculating values of at least one time-varying factor corresponding to a respective one of the variables, each factor value based on at least one second signal value, and applying each factor in an operation in at least one of a number of parallel sequences of operations comprising at least one such operation and taking a signal corresponding to a respective one of the second signals (55-57) as input.

    摘要: A method of processing a signal including at least a component representative of a periodic phenomenon in a living being includes obtaining at least one first signal having at least a component representative of a periodic phenomenon in a living being. Separate data representative of at least a periodic component of motion of the living being are obtained by obtaining a sequence of images showing the living being, synchronized with the at least one first signal, and carrying out video-based motion analysis of the sequence of images. The data are used at least to suppress a component of the first signal corresponding to the periodic component of motion of the living being.
