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.

Abstract: A biometric apparatus includes a light source, an image sensor, a control circuit, and a signal processing circuit. The control circuit causes a light source to repeatedly emit a light pulse radiated onto a target part including a head of a target, causes an image sensor to receive a reflected light pulse which is caused as the light pulse is radiated onto the target part, causes the image sensor to output first image data indicating appearance of a face of the target, and causes the image sensor to output second image data according to distribution of an amount of light of at least one of components of the reflected light pulse. The signal processing circuit generates data indicating a state of the target based on a temporal change in the first image data and a temporal change in the second image data and outputs the data.

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 μs 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.
