Abstract: A camera system includes an imaging device that acquires a first image by a normal exposure including only one exposure and that acquires a second image by a multiple exposure including a plurality of exposures; and an image processor that extracts a feature value of a first object in the first image and that identifies one or more locations corresponding to the feature value in the second image.

Abstract: An imaging device includes: unit pixel cells each including first and second electrodes, a photoelectric conversion layer therebetween, a charge accumulation region, and a signal detection circuit; and a voltage supply circuit, the voltage supply circuit supplying a first voltage to the second electrode in an exposure period. The start and end of the exposure period is common to the unit pixel cells. The photoelectric conversion layer has a photocurrent characteristic including first to third voltage ranges. In the third voltage range between the first and second voltage ranges, an absolute value of a rate of change of a current density relative to a bias voltage is less than in the first and second voltage ranges. The voltage supply circuit supplies a second voltage to the second electrode in a non-exposure period such that the bias voltage applied to the photoelectric conversion layer falls within the third voltage range.

Abstract: An imaging device includes a unit pixel cell. The unit pixel cell captures first data in a first exposure period and captures second data in a second exposure period different from the first exposure period, the first exposure period and the second exposure period being included in a frame period. A sensitivity per unit time of the unit pixel cell in the first exposure period is different from a sensitivity per unit time of the unit pixel cell in the second exposure period. The imaging device outputs multiple-exposure image data including at least the first data and the second data.

Abstract: An imaging device is provided with a pixel array section including multiple pixels arranged in a matrix of rows and columns, and a column signal processor. The multiple pixels include multiple imaging pixels that each output a pixel signal corresponding to incident light and multiple reference pixels which are aligned in the column direction in at least two columns and which each output a reset signal corresponding to the output signal at reset of each of the multiple first pixels. The column signal processor outputs the difference between the pixel signal outputted by one imaging pixel from among the multiple imaging pixels and a reference signal based on the reset signals outputted by at least two reference pixels, from among the multiple reference pixels, located in the same row as the one imaging pixel.

Abstract: An imaging device 100 includes a pixel array PA. A first period, a third period, and a second period appear in this order in one frame. During the first period, pixel signal readout is performed on at least one first row in the pixel array PA. During the second period, pixel signal readout is performed on at least one second row in the pixel array PA. At least one of the at least one first row or the at least one second row includes two rows in the pixel array PA. During the third period, no pixel signal readout is performed on the rows in the pixel array PA. Each of the first period and the second period is one of the high-sensitivity exposure period and the low-sensitivity exposure period. The third period is the other of the high-sensitivity exposure period and the low-sensitivity exposure period.

Abstract: An imaging device includes a semiconductor substrate having a surface, the semiconductor substrate including: a first layer of a first conductivity type; a second layer of a second conductivity type, the second layer being closer to the surface; and a pixel including: a photoelectric converter configured to convert light into charge; a first diffusion region of the first conductivity type, the first diffusion region facing the first layer via the second layer, configured to store at least a part of the charge; and a second diffusion region being a diffusion region closest to the first diffusion region among diffusion regions of the first conductivity type, the diffusion regions facing the first layer via the second layer. A distance between the second diffusion region and the first layer is equal to or less than 1.5 times a distance between the second diffusion region and the first diffusion region.

Abstract: An imaging device includes: an imager that includes first pixels having sensitivity to visible light and second pixels having sensitivity to non-visible light, the imager acquiring first image data from the first pixels and acquiring second image data from the second pixels, each of the first image data and the second image data containing an image of an object that displays a code through non-visible light; and an image processor. The image processor performs a correction process including a process of multiplying at least either the first image data or the second image data by a correction factor, generates third image data from a difference between a pair of image data obtained by the correction process, and extracts the code on the basis of the third image data.
