  • Patent number: 12196614
    Abstract: Disclosed are methods and devices for calibration in the field of optical sensors, e.g. characterizing and calibrating an optical sensor chip. In order to address complexity of sensor data with high accuracy the optical sensor, e.g. an optical sensor is not provided as an already calibrated unit. Rather, sensor response data may be recorded in a defined or standardized environment, e.g. at a production line, and with high precision. This high standard sensor response data can be obtained on a per device basis and, thus, is referenced with an unambiguous chip identification number, chip ID. The sensor data is complemented with a dedicated calibration algorithm which can be tailor-made to fit the optical sensor or the optical sensor chip. In order to retrieve the sensor response data and the calibration algorithm both can be made available by means of the chip ID, for example.

    Abstract: A dual mode camera may have a camera module and a light source. The camera module may include a quasi-bandpass filter for passing visible light and passing an attenuated portion of near-infrared light to an image sensor for detection. A processor may determine an ambient lighting condition corresponding with an amount of ambient visible light detected by a photodetector. In response to a first ambient lighting condition, the processor may send a first control signal to an encoder to encode image data in monochrome, and another signal to activate a light source. In response to a second ambient lighting condition, the processor may send a second control signal to the encoder to encode image data in color. The light source may emit a band of near-infrared light corresponding with an atmospheric absorption band. The quasi-bandpass filter may attenuate a portion of near-infrared light corresponding with the same atmospheric absorption band.

  • Patent number: 11727709
    Abstract: A light source (11) of a disguising mask detecting device (1) emits light at a person who is a subject. A camera (12) acquires images in multiple different wavelength ranges of reflected light of the light emitted at the person. A face detector (172) detects a face region of the person from the images acquired by the camera (12). A determiner (173) determines that the person is wearing a disguising mask when luminances of the face region in the images satisfy specific relations different from relations exhibited by skin.
