The invention provides a system and method for measuring vital signs (e.g. SYS, DIA, SpO2, heart rate, and respiratory rate) and motion (e.g. activity level, posture, degree of motion, and arm height) from a patient. The system features: (i) first and second sensors configured to independently generate time-dependent waveforms indicative of one or more contractile properties of the patient's heart; and (ii) at least three motion-detecting sensors positioned on the forearm, upper arm, and a body location other than the forearm or upper arm of the patient. Each motion-detecting sensor generates at least one time-dependent motion waveform indicative of motion of the location on the patient's body to which it is affixed. A processing component, typically worn on the patient's body and featuring a microprocessor, receives the time-dependent waveforms generated by the different sensors and processes them to determine: (i) a pulse transit time calculated using a time difference between features in two separate time-dependent waveforms, (ii) a blood pressure value calculated from the time difference, and (iii) a motion parameter calculated from at least one motion waveform.

Motion sensing of a portable device using two cameras. A first camera is directed along a first viewing axis and a second camera is directed along a second viewing axis, different from the first viewing axis. The second viewing axis can be substantially opposite the first viewing axis. A motion processing module determines changes in images from the first camera and changes in images from the second camera. The motion processing module compares the direction of change determined from the first camera images relative to the direction of change determined from the second camera images. The motion processing module determines the motion of the portable device based in part on the comparison.

A dual mode digital imaging system has a still processing mode that produces an output image in a first color space and a motion processing mode that produces an output image in a second color space, in particular a first color space that is RGB and a second color space that is YUV. The digital imaging system includes a dual mode digital camera for use with a computer and a processing application for running on the computer, wherein the motion mode processing is relatively less complex than the still mode processing although at least one common control parameter is used to control both modes. The motion mode processing, which is performed using algorithms and software approaches designed to minimize processing time, nonetheless produces an entirely adequate relatively low resolution YUV image appropriate for applications such as videoconferencing. The still mode processing, on the other hand, uses more elaborate algorithms to optimize the image quality of a relatively high resolution RGB output image.

A video converter provides for converting an interlaced video datastream to a de-interlaced form suitable for progressive-input coding. Conversion is conducted in accordance with determined motion of image portions within the video datastream. In a preferred MPEG-1 and MPEG-2 IC pre-processor implementation, during motion processing, intra-frame and inter-frame motion analyses are conducted for a current-pixel. The resulting motion determinations are further correlated with derived and/or coding metrics and combined; the combination is also limited, smoothed and a transfer function is applied to produce a mix control. During further video processing, current-pixel data from a current field (“field data”) and corresponding filtered current frame data (“filtered frame data”) are mixed in accordance with the mix control. Resulting output preferably comprises filtered frame data for low or no determined motion, field data for high motion and motion-related mixtures of the two for remaining motion determinations.

A motion stabilization system including a filter bank and motion stabilization logic. The filter bank receives a video signal and provides at least one high frequency sub-band signal which includes edge information of the video signal.
