    Abstract: An imaging device includes: a light source that applies light at a timing according to a light emission control signal; a light receiver that performs exposure to reflected light from an object at different timings according to an exposure control signal, and outputs exposure signals generated as a result of the exposure; a calculator that calculates a distance to the object; and a controller that outputs the light emission control signal and the exposure control signal for any of: modulating a length of a light emission period and an exposure period by increasing or decreasing the number of pulses of each of the light emission control signal and the exposure control signal; and modulating a repetition sequence of the light emission period and the exposure period while maintaining a phase relationship between the light emission control signal and the exposure control signal, randomly or in conformity with a specific rule.

    Abstract: An image-capturing device includes an infrared light source configured to emit infrared light, and a solid-state image-capturing device including a plurality of first pixels configured to convert visible light into signal charge and a plurality of second pixels configured to convert infrared light into signal charge, the plurality of first pixels and the plurality of second pixels being arranged on a semiconductor substrate in a matrix. The solid-state image-capturing device outputs, during the same single frame scanning period, a first signal obtained from the plurality of first pixels, a second signal obtained from the plurality of second pixels during a period of time when the infrared light is emitted, and a third signal obtained from the plurality of second pixels during a period of time when the infrared light is not emitted.

    Abstract: A solid-state imaging device includes a plurality of pixels arranged in matrix form, each pixel including a photoelectric converter and a plurality of first transfer electrodes, and a plurality of control lines connected to mutually-corresponding ones of the first transfer electrodes in a plurality of pixels arranged in a specific row. The plurality of pixels include a plurality of first pixels and second pixels. Each of the first pixels includes a floating diffusion layer and a readout circuit. Each of the second pixels shares the floating diffusion layer with one of the first pixels arranged in a column direction. At least some of the plurality of control lines are further connected to the first transfer electrodes of pixels that are arranged adjacent in the column direction to respective ones of the plurality of pixels arranged in the specific row and that share at least one of the floating diffusion layers.

    Abstract: A solid-state imaging device includes: an imager including pixels arranged in rows and columns; vertical transfer portions in one-to-one correspondence with columns of the pixels, each of which includes a readout electrode that reads out signal charges generated in the pixels and a transfer electrode that transfers the read-out signal charges in the column direction; and a horizontal transfer portion which transfers, in the row direction, the signal charges transferred by the vertical transfer portions, and outputs the signal charges. The imager is formed by alternately disposing, in the column direction, a first row in which visible light pixels each including a first photoelectric converter that converts visible light into signal charges are arranged adjacent in the row direction and a second row in which infrared light pixels each including a second photoelectric converter that converts infrared light into signal charges are arranged adjacent in the row direction.

    Abstract: A solid-state imaging device includes pixels arranged in matrix form, each including a photoelectric converter and first transfer electrodes, and control lines connected to mutually-corresponding ones of the first transfer electrodes in pixels arranged in a specific row. The pixels include first pixels that receive visible light and second pixels that receive infrared light. Each of floating diffusion layer-including pixels, which are some of the plurality of pixels, further includes a floating diffusion layer and a readout circuit. Each floating diffusion layer-lacking pixel shares the floating diffusion layer with one of the first pixels arranged in a column direction. At least some of the control lines are further connected to the first transfer electrodes of pixels arranged adjacent in the column direction to respective ones of the pixels arranged in the specific row and that share at least one of the floating diffusion layers.
