  • Publication number: 20210085229
    Abstract: A biometric measurement apparatus includes a light source that emits light onto a head portion of a user, an image sensor, a controller that controls the light source and the image sensor, and a signal processor. The controller causes the light source to emit the light and causes the image sensor to output an image signal by causing the image sensor to detect at least part of reflected light returning from the head portion in response to emission of the light. The signal processor generates brain activity data indicating a state of a brain of the user and stops outputting the brain activity data based on at least one selected from the group consisting of the image signal and a sensor signal output from a sensor that detects a change, affecting the brain activity data, in an environment surrounding the user.

  • Publication number: 20210049252
    Abstract: An identifying device includes a light source, an image sensor, a memory that stores biometric data indicating a feature of a body of a user, and a processor. The processor causes the light source to emit pulsed light having a pulse duration of more than or equal to 0.2 ns and less than or equal to 1 ?s to illuminate the user with the pulsed light, causes the image sensor to detect at least part of reflected pulsed light that returns from the user and to output a signal corresponding to two-dimensional distribution of an intensity of the at least part of the reflected pulsed light, and verifies the signal against the biometric data to identify the user.

  • Patent number: 10911697
    Abstract: An imaging apparatus including a light source that, in operation, emits pulsed light to a measurement target; a diffusion member that is disposed between the light source and the measurement target, and diffuses the pulsed light; an image sensor that includes at least one pixel, the at least one pixel including a photodiode and a charge accumulator that, in operation, accumulates signal charge from the photodiode; and a control circuit that, in operation, controls the image sensor. The control circuit causes the image sensor to start to accumulate the signal charge with the charge accumulator in a falling period of a returned pulsed light which is returned from the measurement target to the image sensor due to the emission of the pulsed light, the falling period being a period from start to end of a decrease of an intensity of the returned pulsed light.
