Abstract: To improve a frame rate in a solid-state imaging element that compares a reference signal and a pixel signal.
The solid-state imaging element includes a differential amplifier circuit, a transfer transistor, and a source follower circuit. The differential amplifier circuit amplifies a difference between the potentials of a pair of input nodes and outputs the difference from an output node. The transfer transistor transfers charge from a photoelectric conversion element to a floating diffusion layer. The auto-zero transistor short-circuits the floating diffusion layer and the output node in a predetermined period. The source follower circuit supplies a potential to one of the pair of input nodes according to a potential of the floating diffusion layer.-

Abstract: Solid-state imaging elements are disclosed. In one example, an upstream circuit sequentially generates a predetermined reset level and a signal level corresponding to an exposure amount, and causes first and second capacitive elements to hold the reset level and the signal level. A selection circuit sequentially connects one of the capacitive elements to a predetermined downstream node, disconnects both capacitive elements from the downstream node, and connects the other capacitive element to the downstream node. A downstream reset transistor initializes a level of the downstream node when both capacitive elements are disconnected from the downstream node. A downstream circuit sequentially reads the reset level and the signal level from the first and second capacitive elements via the downstream node and outputs the reset level and the signal level.

Abstract: An imaging device includes a first pixel and a second pixel. The first pixel includes a first photoelectric converter that generates first signal charge by photoelectric conversion and that has sensitivity to a first wavelength range that is invisible and a first signal detection circuit connected to the first photoelectric converter. The second pixel includes a second photoelectric converter that generates second signal charge by photoelectric conversion and that has sensitivity to a second wavelength range and a second signal detection circuit connected to the second photoelectric converter. An exposure period of the second photoelectric converter does not overlap a light-emitting period of light based on lighting, the light being incident on the first photoelectric converter and having a luminescence peak in the first wavelength range. A readout period during which the second signal detection circuit reads out the second signal charge does not overlap the light-emitting period.

Abstract: 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.

Abstract: Electronic apparatuses that prevent image quality deterioration of an image captured by a camera while reducing a bezel width are disclosed. In one example, an electronic app mprises a display including a display surface, a first image sensor configured to detect light in a direction incident upon the display surface and arranged under the display surface in a cross sectional view, and a second image sensor disposed separately from the first image sensor, the second image sensor being configured to detect light in the direction incident upon the display surface and arranged at a level lower than the display surface in the cross sectional view. The sensitivity of the first image sensor to a first wavelength band that includes blue light is higher than sensitivity of the second image sensor to the first wavelength band.
