  • Patent number: 10771683
    Abstract: Accurate motion detection is performed by discriminating whether a sensor detecting an object motion is mounted on a human body or not, and processing is executed with respect to metadata based on the result. Sensor information according to the motion is input from the sensor, and a sensor mounting position is determined. A sensor mounting position detection unit calculates a ratio between a high-frequency component and a low-frequency component included in the sensor information, and discriminates whether the sensor is mounted on the human body or is mounted on other than the human body, on the basis of the calculated ratio. A metadata generating unit inputs user motion detection information obtained by executing a motion detection algorithm assuming a sensor mounting position coincident with a sensor mounting position detection result, and generates the shot image corresponding metadata.

  • Patent number: 10750959
    Abstract: A system and method for real time estimation of heart rate (HR) from one or more face videos acquired in non-invasive manner. The system receives face videos and obtains several blocks as ROI consisting of facial skin areas. Subsequently, the temporal fragments are extracted from the blocks and filtered to minimize the noise. In the next stage, several temporal fragments are extracted from the video. The several temporal fragments, corrupted by noise are determined using an image processing range filter and pruned for further processing. The HR of each temporal fragment, referred as local HR is estimated along with its quality. Eventually, a quality based fusion is applied to estimate a global HR corresponding to the received face videos. In addition, the disclosure herein is also applicable for frontal, profile and multiple faces and performs in real-time.

  • Patent number: 10561323
    Abstract: A pulse oximetry measurement system uses a pseudo-random noise generator to stimulate one or more light emitting diodes (LEDs). The light amplitudes from these LEDs, after passing through a part of a body, are detected by a phototransistor or photodiode and digitized with an analog-to-digital converter (ADC). The digitized ADC light amplitude values are re-correlated with the outgoing pseudo-random noise stimulus. Spread spectrum techniques are known for their noise mitigation properties, and ability to pass multiple signals through the same medium without interference. Thus, these measurements can be performed substantially simultaneously with minimal interference from each other.
