摘要： Provided are a solid-state imaging device, a method for driving a solid-state imaging device, and an electronic apparatus that are capable of selecting a pixel operating mode between a RS mode and a GS mode and switching a conversion gain read-out mode, where signals produced with different conversion gains are read, among several options depending on a scene. As a result, the solid-state imaging device, the method for driving the solid-state imaging device and the electronic apparatus can minimize a drop in SNR at the conjunction point between a HCG signal and a LCG signal and also achieve high full well capacity and little dark noise. In a solid-state imaging device, a pixel part includes pixels arranged in a matrix pattern, and each pixel includes a photoelectric conversion reading part. The solid-state imaging device is capable of performing rolling shutter (RS) and global shutter (GS).

摘要： A source follower element is adjacent to a first lateral part of a floating diffusion in a first direction orthogonal to the first lateral part, a reset element is adjacent to a second lateral part of the floating diffusion in the first direction, and the floating diffusion and the source follower element are connected through a wiring. Some of the photoelectric conversion elements are adjacent to each other in a second direction and spaced away from each other with a first spacing therebetween that allows at least the source follower element and the reset element to be formed therein. Some of the photoelectric conversion elements are adjacent to each other in the first direction and spaced away from each other with a second spacing therebetween that is less than the first spacing.

摘要： Provided are a solid-state imaging device, a method for manufacturing a solid-state imaging device and an electronic apparatus that are capable of achieving maximized photo-responsiveness, ensuring low optical SNR in addition to reproducibility, and further reducing the pixel size, thereby efficiently improving important performance factors such as the dynamic range, responsiveness, and resolution. The charges integrated in a first photoelectric conversion element are stored in a storage node, and charges overflowing from the first photoelectric conversion element are stored in a floating diffusion. The charges integrated in a second photoelectric conversion element are stored in a storage node, and charges overflowing from the second photoelectric conversion element are discharged to the region that is not occupied by the floating diffusion.

摘要： A pixel circuit 200 includes a readable pixel 210, a comparator 220, and a selector counter circuit 230. The readable pixel 210 performs photoelectric conversion at a photodiode PD11 and produces a readable signal corresponding to an illuminance condition of incident light. The readable pixel 210 includes an overflow path extending to a floating diffusion FD11. The comparator 220 compares a voltage signal (SFout) read out from the readable pixel 210 against a reference signal Vref and outputs a comparison result signal Vout indicating the result of the comparison. The selector counter circuit 230 includes a selector circuit for selecting an external clock or the output Vout from the comparator and a counter circuit for counting the output from the selector circuit.

摘要： Provided are a solid-state imaging device, a method for driving a solid-state imaging device and an electronic apparatus. A reading part controls an output node, a first storage node and a second storage node such that the output node, the first storage node and the second storage node are coupled with each other to perform reading of an overflow charge signal, and controls the output node and the second storage node such that the output node and the second storage node are separated from each other to perform reading of a stored charge signal. A sequence of operations to read the pixel signal is performed such that the reading of the overflow charge signal takes place prior to the reading of the stored charge signal without charge mixing at the output node.

摘要： Some embodiments relate to an active pixel for use in a digital pixel sensor (DPS) imaging system having complete intra-pixel charge transfer functionality. The active pixel may include a first photodiode, and a first transfer gate and a second transfer gate each operatively coupled to the first photodiode. The first transfer gate and the second transfer gate may reside at opposite sides of the first photodiode. An electron drift current within the first photodiode may cause two direction charge transfer of charge of the first photodiode to the first transfer gate and the second transfer gate.

摘要： A solid-state imaging device, a method for driving the same, and an electronic apparatus can achieve a high dynamic range based on multiple exposure technique, where images captured with different exposure durations are combined, with it being possible to prevent motion artifacts and LED flickers. A pixel has a 4:0 configuration. The pixel is divided into, for example, four sub-pixels all of which have the same color (for example, G (green)). An access control part sets different charge integration periods and different charge storage starting times between photoelectric conversion parts PD of the sub-pixels and controls the charge integration periods such that they overlap each other. In other words, the access control part sets different charge integration periods and different charge storage starting times, the number of which corresponds to the number of sub-pixels having the same color, and controls the charge integration periods such that they overlap each other.
