Abstract: A solid-state imaging device includes a substrate of P type and a wiring layer. The substrate includes: a first semiconductor region disposed on a first principle surface and extending in a direction from the first principal surface toward the second principal surface; a second semiconductor region disposed between the second principal surface and the first semiconductor region and connected to the first semiconductor region; a P type semiconductor region disposed between the second principal surface and the second semiconductor regions of two pixels; and a pixel isolation region disposed inside the substrate, between the first semiconductor regions of the two pixels. The second semiconductor region and the P type semiconductor region form an avalanche multiplication region.

Abstract: It is made possible to monitor the periphery of a target object more accurately, using an imaging device that generates distance image data by sub-range analysis. For a target object present across first and second distance zones adjacent to each other, a first position at a near end position of the first distance zone, a second position at a boundary position between the first and second distance zones, and a third position indicating the position at a far end position of the second distance zone are obtained. Location data of the target object is generated based on location information of the second position with respect to a straight line connecting the first position and third position.

Abstract: The present disclosure allows a light-emitting device to detect a failure of a light-emitting circuit without affecting the waveform of a pulse current to be supplied to a light source element. The light-emitting device includes: a light-emitting circuit including a light source element; and a power supply configured to supply electric charges to the light-emitting circuit. The light-emitting circuit is provided between a power supply node and a ground node. The power supply is connected to the power supply node via a power supply line. A monitor detects an abnormal state of the light-emitting circuit by monitoring the voltage of the power supply line or the internal voltage of the power supply.
