Abstract: A plurality of pixels of a solid-state imaging device include: a photoelectric converter which receives light from an object and converts the light into charge; a plurality of readers which read the charge from the photoelectric converter; a plurality of charge accumulators each of which accumulates the charge of the photoelectric converter read from the plurality of readers; and a transfer controller which performs a transfer control including controlling whether the charge accumulated in one of the plurality of charge accumulators is transferred or blocked from being transferred to another one of the plurality of charge accumulators. The transfer controller is disposed between the plurality of charge accumulators.

Abstract: A distance measurement system includes: a signal generator which generates a light emission signal that instructs light emission and an exposure signal that instructs exposure of reflected light; a first illumination and distance measurement light source which receives the light emission signal and, according to the signal received, performs the light emission for illumination without a purpose of distance measurement and the light emission with the purpose of distance measurement using the reflected light; an imaging device which receives the exposure signal, performs the exposure according to the signal received, and obtains an amount of light exposure of the reflected light; and a calculator which calculates distance information using the amount of light exposure and outputs the distance information, wherein the distance measurement system has operation modes including an illumination mode and a first distance measurement mode.

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: Provided is a method for driving a solid-state imaging device including a unit pixel which includes at least a first pixel including: a photoelectric converter which receives reflected light from an object and converts the reflected light into charge; an exposure resetter which switches between exposure and discharge of the charge in the photoelectric converter; and a plurality of readers which read the charge from the photoelectric converter and include at least a first reader and a second reader. The method includes: performing a first exposure as the exposure that is performed in a first period in which a gate of the first reader is ON; and performing a second exposure as the exposure that is performed in a second period which is started in conjunction with the end of the first period and in which a gate of the second reader is ON.
