摘要： A system includes a focal plane array having multiple pixel circuit elements. Each pixel circuit element includes a photodetector configured to generate an electrical current based on received illumination. Each pixel circuit element also includes a capacitor configured to be charged by the electrical current and generate a voltage. Each pixel circuit element further includes a controller configured to sense whether the voltage on the capacitor exceeds a threshold during a sampling period. In addition, each pixel circuit element includes a timer configured to generate an estimate or measure of an amount of time within the sampling period during which the voltage on the capacitor does not exceed the threshold.

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： One example apparatus for providing a dual pixel array includes an array of pixels, each pixel comprising a plurality of photodiodes, each photodiode configured to generate a charge in response to incoming light and connected to at least one charge storage device. The plurality of photodiodes comprises one or more color photodiodes each including a chromatic filter, a color-select switch, and having at least one associated monochrome photodiode with a monochrome filter and a monochrome-select switch. The dual pixel array further comprises one or more analog-to-digital converters (“ADC”), each ADC connected to at least one of the charge storage devices of the photodiodes via the respective select switch, configured to selectively convert one or more stored voltages into a pixel value in response to a control signal. The color photodiodes and the monochrome photodiodes are arranged according to an arrangement.

摘要： [Problem] To expand the dynamic range, increase the frame rate, and reduce power consumption during photoelectric conversion.
[Solution] An imaging device includes a pixel unit that outputs a photoelectrically converted pixel signal to a signal line, an AD converter that performs AD conversion on the pixel signal on the signal line and determines illuminance based on the pixel signal, and a switching circuit that switches whether to input the pixel signal on the signal line to the AD converter and whether to output the illuminance determination signal determined by the AD converter to the signal line in conjunction with each other. The pixel unit includes a first photoelectric conversion portion, a conversion efficiency adjustment circuit that switches the conversion efficiency when converting the charge photoelectrically converted by the first photoelectric conversion portion into voltage, a first readout circuit that outputs a pixel signal corresponding to the charge photoelectrically converted by the first photoelectric conversion portion to the signal line, and a holding circuit that holds the determination signal.-
