Publication number: 20220159217Abstract: A camera system. The camera system includes a sensor array; an infrared (IR) illumination system configured to emit active IR light in an IR light sub-band; a spectral illumination system configured to emit active spectral light in a spectral light sub-band; one or more logic machines; and one or more storage machines. The storage machines hold instructions executable by the one or more logic machines to address the sensor array to acquire an ambient image; based on at least the ambient image, activate the IR illumination system and address the sensor array to acquire an actively-IR-illuminated depth image; and based on at least the actively-IR-illuminated depth image, activate the spectral illumination system and address the sensor array to acquire an actively-spectrally-illuminated spectral image.Type: ApplicationFiled: February 2, 2022Publication date: May 19, 2022Applicant: Microsoft Technology Licensing, LLCInventors: Sergio ORTIZ EGEA, Riaz Imdad ALI, Michael Scott FENTON, Onur Can AKKAYA

Patent number: 11245875Abstract: A camera system is configured to automatically monitor an area. Depth image(s) of the area are acquired based on active IR light emitted by the camera system and reflected from the area to a sensor array of the camera system. The depth image(s) are computer analyzed to identify a human subject. For each spectral illuminator of the camera system, spectral light image(s) of the area are acquired based on active spectral light in the spectral light sub-band of the spectral illuminator reflected from the area to the sensor array. The spectral light image(s) for the spectral illuminators are computer analyzed to identify an interaction between the human subject and an object in the area. In response to identifying the interaction between the human subject and the object in the area, an action to be performed for the object in the area is computer issued.Type: GrantFiled: January 15, 2019Date of Patent: February 8, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Sergio Ortiz Egea, Riaz Imdad Ali, Michael Scott Fenton, Onur Can Akkaya

Patent number: 10996169Abstract: A camera system includes one or more spectral illuminators, a tunable optical filter, and a sensor array. Active spectral light emitted from the one or more spectral illuminators towards a scene is dynamically tuned to an illumination sub-band selected from a plurality of different illumination sub-bands. Sequentially for each of a plurality of fluorescing light sub-bands different than the selected illumination sub-band, the tunable optical filter is adjusted to block light from being transmitted from the scene to the sensor array in all but a tested fluorescing light sub-band from the plurality of different fluorescing light sub-bands, and the sensor array is addressed to acquire one or more image of the scene in the tested fluorescing light sub-band.Type: GrantFiled: February 27, 2019Date of Patent: May 4, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Sergio Ortiz Egea, Maria Esther Pace, Onur Can Akkaya, Michael Scott Fenton

Patent number: 10924692Abstract: A camera includes a time-of-flight illuminator configured to emit active IR light and a plurality of spectral illuminators, each spectral illuminator configured to emit active spectral light in a different spectral light sub-band. The camera further includes a sensor array that includes a plurality of differential sensors. Each differential sensor is configured to differentially measure both 1) the active IR light, and 2) the active spectral light in each of the different spectral light sub-bands. The camera further includes an output machine operatively connected to the sensor array. The output machine is configured to output a matrix of pixels based on time-multiplexed measurements of the sensor array. Each pixel of the matrix includes 1) a depth value, and 2) a plurality of spectral values. Each of the plurality of spectral values corresponds to a spectral light sub-band of one of the plurality of spectral illuminators.Type: GrantFiled: May 8, 2018Date of Patent: February 16, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Sergio Ortiz Egea, Michael Scott Fenton, Cyrus Soli Bamji

Patent number: 10785422Abstract: A camera is configured to output a test depth+multi-spectral image including a plurality of pixels. Each pixel corresponds to one of the plurality of sensors of a sensor array of the camera and includes at least a depth value and a spectral value for each spectral light sub-band of a plurality of spectral illuminators of the camera. A face recognition machine is previously trained with a set of labeled training depth+multi-spectral images having a same structure as the test depth+multi-spectral image. The face recognition machine is configured to output a confidence value indicating a likelihood that the test depth+multi-spectral image includes a face.Type: GrantFiled: May 29, 2018Date of Patent: September 22, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Sergio Ortiz Egea, Michael Scott Fenton, Abdelrehim Ahmed

Publication number: 20200036880Abstract: Examples are disclosed that relate to methods and systems for determining if a fluid is present on a surface. In one example, a method comprises illuminating the surface with narrow-band light and using an image sensor comprising a narrow-bandpass filter matching the bandwidth of the narrow-band light to obtain a first image of the surface. A second image of the surface with the narrow-band light deactivated is obtained. A third image is generated by subtracting the second image from the first image. The third image is thresholded, one or more contrasting regions are detected, and the presence of fluid on the surface is determined.Type: ApplicationFiled: July 25, 2018Publication date: January 30, 2020Applicant: Microsoft Technology Licensing, LLCInventors: Sergio ORTIZ EGEA, Michael Scott FENTON, Venkata Satya Raghavendra BULUSU, Riaz Imdad ALI
