Abstract: Read electrodes are provided to drain signal charge of pixels from photoelectric conversion units provided in the pixels separately to a vertical transfer unit. During a first exposure period during which an object is illuminated with infrared light, signal charge obtained from a first pixel, and signal charge obtained from a second pixel adjacent to the first pixel, are added together in the vertical transfer unit to produce first signal charge. During a second exposure period during which the object is not illuminated with infrared light, signal charge obtained from the first pixel, and signal charge obtained from the second pixel adjacent to the first pixel, are transferred without being added to the first signal charge in the vertical transfer unit, and are added together in another packet to produce second signal charge.

Abstract: A distance-measuring/imaging apparatus having a high S/N and a high distance measurement accuracy is provided. The distance-measuring/imaging apparatus includes: a signal generation unit for generating an emission signal and exposure signal; a light source unit for performing light irradiation by receiving the emission signal; an imaging unit for performing exposure by receiving the exposure signal and for acquiring the exposure amount of the reflected light; and a calculation unit for calculating and outputting the distance information on the basis of the exposure amount. The imaging unit acquires a first exposure amount corresponding to the exposure in a first emission/exposure period, in which the exposure is performed by receiving the exposure signal simultaneously with a receiving timing of the emission signal. The imaging unit acquires a second exposure amount corresponding to the exposure in a second emission/exposure period, in which the exposure is performed by receiving the exposure signal after a lapse of a delay time from the receiving timing of the emission signal. The calculation unit calculates the distance information on the basis of the first exposure amount and second exposure amount that are acquired by changing the repeat count of the emission signal in the first emission/exposure period.

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.
