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 distance-measuring imaging device includes: a drive control unit; a light source unit; an image processing unit including light receiving units and charge reading units arranged one-to-one; and an image processing unit. The charge reading units are arranged partly at the left side of corresponding ones of the light receiving units and partly at the right side of corresponding ones of the same. In each of a period in which the exposure is performed when the exposure control signal is received after a first delay time since when the light emission control signal is received and a period in which the exposure is performed when the exposure control signal is received after a second delay time longer than the first delay time, since when the light emission control signal is received, the left-side charge reading units read charge leftward, and the right-side charge reading units read charge rightward.
