    摘要： The present invention is a solid-state imaging device including: a pixel array section including a plurality of unit pixels capable of accumulating charge photoelectrically converted by a photoelectric conversion section in a predetermined floating diffusion (FD) region; a system control section that controls the pixel array section; and a pixel signal reading mechanism that reads a pixel signal based on the charge from the predetermined FD region of a unit pixel of the plurality of unit pixels under control of the system control section. The pixel signal reading mechanism may include an AD converter that performs AD conversion processing on the pixel signal read, and a determination section that performs brightness/darkness determination of light received by the unit pixel on the basis of the pixel signal read in a determination phase. The determination section selectively controls execution or stop of the AD conversion processing by the AD converter on a pixel signal to be subsequently read according to a result of the determination.

    摘要： An imaging device includes pixel sensors. A drive-sense circuit is configured to generating a sensed signal corresponding to one of pixel sensors. The drive-sense circuit includes: a first conversion circuit configured to convert, a receive signal component of a sensor signal corresponding to the one of the pixel sensors into the sensed signal, wherein the sensed signal indicates a change in a capacitance associated with the one of the pixel sensors; a second conversion circuit configured to generate, based on the sensed signal, a drive signal component of the sensor signal corresponding to the one of the pixel sensors. The drive-sense circuit is further configured to generate other sensed signals corresponding to other ones of the pixel sensors for the other ones of the pixel sensors. A graphics processing module is configured to generate image data based on the sensed signal and the other sensed signals.

    摘要： Provided are a solid-state imaging device, a method for driving a solid-state imaging device and an electronic apparatus capable not only of having advanced global shutter and autofocus functions but also of sufficiently achieving single exposure high dynamic range (SEHDR) performance, thereby substantially realizing enhanced dynamic range and frame rate.
    In an image capturing mode, a reading part controls driving of a conversion signal reading part such that the conversion signal reading part keeps first and second transfer transistors in a conduction state in the same transfer period and performs a read-out operation on a pixel signal corresponding to a sum of charges stored in a first photodiode and charges stored in a second photodiode with a first conversion gain and subsequently with a second conversion gain.

    摘要： An imaging device including: a first imaging cell including a first photoelectric converter that generates a first signal; and a second imaging cell including: a second photoelectric converter that generates a second signal; and a capacitor having a first and second terminal, the first terminal electrically coupled to second photoelectric converter. An area of the first photoelectric converter is greater than an area of the second photoelectric converter in a plan view, the first imaging cell has a first number of saturation charges, and the second imaging cell has a second number of saturation charges, the first number of saturation charges is greater than the second number of saturation charges, and the capacitor has capacitance that causes the second number of saturation charges of the second imaging cell to become greater than the first number of saturation charges of the first imaging cell.
