CMOS像素、图像传感器、摄像机和用于读取CMOS像素的方法
Abstract:
一种CMOS像素，该CMOS像素具有双转换增益读取电路，该双转换增益读取电路具有至少一个第一光电二极管(PD1)、扩散区域(FD)，该扩散区域具有第一电容(CFD)，该第一电容用于接收至少一个第一光电二极管(PD1)的电荷，其中，该双转换增益读取电路构造用于借助第一增益因子并且借助第二增益因子来读取扩散区域(FD)的电荷，其中，CMOS像素具有至少一个第二光电二极管(PD2)，其中，该扩散区域(FD)还构造用于接收至少一个第二光电二极管(PD2)的电荷，并且该双转换增益读取电路构造用于借助至少一个第三增益因子和至少一个第四增益因子来读取扩散区域(FD)的电荷。
Abstract(English):

CMOS pixel having a dual conversion gain read-out circuit, comprising at least one first photodiode (PD1), a diffusion region (FD) having a first capacitance (CFD) for taking up a charge from the at least one first photodiode (PD1), wherein the dual conversion gain read-out circuit is configured to read out the charge of the diffusion region (FD) by means of a first gain factor and by means of a second gain factor, wherein the CMOS pixel comprises at least one second photodiode (PD2), wherein the diffusion region (FD) is furthermore configured to take up a charge from the at least one second photodiode (PD2), and wherein the dual conversion gain read-out circuit is configured to read out the charge of the diffusion region (FD) by means of at least one third gain factor and at least one fourth gain factor.
