摘要： In an imaging device, a photoelectric converter of a first pixel and a photoelectric converter of a second pixel are arranged along a first direction. At least part of a charge accumulation portion of the first pixel is disposed between the photoelectric converter of the first pixel and the photoelectric converter of the second pixel. An exit surface of a light guiding path of the first pixel is longer in a second direction orthogonal to the first direction in plan view than in the first direction.

摘要： 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.

摘要： A color and infrared image sensor includes a silicon substrate, MOS transistors formed in the substrate, a stack covering the substrate and including a first photosensitive layer, an electrically-insulating layer, a second photosensitive layer, and color filters. The image sensor further includes electrodes on either side of the first photosensitive layer and delimiting first photodiodes, and electrodes on either side of the second photosensitive layer and delimiting second photodiodes. The first photosensitive layer absorbs the electromagnetic waves of the visible spectrum and of a portion of the infrared spectrum and the second photosensitive layer absorbs the electromagnetic waves of the visible spectrum and gives way to the electromagnetic waves of the portion of the infrared spectrum.

摘要： An image sensor with noise-reduction circuitry includes a pixel array, many analog-to-digital converters, and many correlated dual sampling units. The pixel array includes rows and columns of pixel cells. Each of the pixel cells converts light into analog electrical signal. Analog-to-digital converters convert the electric signals output from the pixel cells into digital signals. The correlated dual sampling units convert the digital signals and/or the electric signals into correlated dual sampling signals to denoise the output of the image sensor by subtraction from the analog content. An electronic device is also provided.

摘要： An amplifier transistor within an image-sensor pixel is implemented upside down relative to conventional orientation such that a substrate-resident floating diffusion node of the pixel forms the gate of the amplifier transistor—achieving increased pixel conversion gain by eliminating the conventional metal-layer interconnection between the floating diffusion node and amplifier-transistor gate and concomitant parasitic capacitance.
