Abstract: An imaging device includes: a photoelectric converter that includes first and second electrodes and a photoelectric conversion layer therebetween and that generates signal charge; a capacitor having first and second terminals, the first terminal being connected to the first electrode; a first voltage supply circuit that selectively supplies at least two different voltages to the second electrode; and a second voltage supply circuit that selectively supplies at least two different voltages to the second terminal. In a predetermined period in each frame, when the first voltage supply circuit supplies a first voltage to the second electrode, the second voltage supply circuit supplies a second voltage to the second terminal, and when the first voltage supply circuit supplies a third voltage higher than the first voltage to the second electrode, the second voltage supply circuit supplies a fourth voltage lower than the second voltage to the second terminal.

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: A distance measurement device includes a light source that projects pulse light toward an object, a detector that receives reflected light of the projected pulse light from the object, the detector including a first pixel having sensitivity that is variable, and a control unit. The light source projects first pulse light in a first period. The control unit sets the sensitivity of the first pixel to sensitivity α1 in a second period and sets the sensitivity of the first pixel to sensitivity α2 different from the sensitivity α1 in a third period following the second period. A length of the second period is equal to a length of the first period. A start time of the second period is after a start time of the first period. The second period and the third period are included in a first light-reception period.

Abstract: An imaging device includes: a photoelectric converter whose sensitivity changes depending on a value of a voltage to be applied; and a voltage supply circuit that alternately supplies a first voltage and a second voltage, which is different from the first voltage, to the photoelectric converter, in which in a first frame period, a length of a first period from a first point in time at which the first voltage is switched to the second voltage until a second point in time at which the first voltage is switched to the second voltage subsequently to the first point in time differs from a length of a second period from the second point in time until a third point in time at which the first voltage is switched to the second voltage subsequently to the second point in time.

Abstract: An imaging device includes an imaging unit including a plurality of pixels, respectively including photoelectric converters and charge accumulation nodes that accumulate signal charge. The imaging unit outputs image data based on signals corresponding to the signal charge accumulated in the charge accumulators. The imaging device includes an image processing unit that processes the image data output by the imaging unit. The imaging unit sequentially outputs a plurality of pieces of image data in one frame period by performing readout nondestructively. The image processing unit generates difference image data by determining a difference between two pieces of image data, selects output image data from initial image data and the difference image data, and combines the output image data and normal readout image data included in the plurality of pieces of image data, to generate combination-result image data.
