Method of reading out a CMOS image sensor and a CMOS image sensor configured for carrying out such method
Abstract:
The invention relates to a method of reading out a CMOS image sensor. The method includes setting a pixel (Pxl) in a first mode (SS) and resetting the pixel (Pxl) so the predefined voltage (V-ref) is set over the photo-diode (Dde) and the first capacitance (C_low). The method further includes collecting charge carriers that reduce the pixel potential (Vp) on the photo-diode (Dde). The method further includes reading out the pixel (Pxl) while in the first mode (SS) and a second mode (LS), and storing the pixel potential (Vp). The method further includes resetting the pixel (Pxl) such that the predefined voltage (V_ref) is over the photo-diode (Dde), the first capacitance (C_low), and the second capacitance (C_high). The method further includes reading out the pixel (Pxl) while in the second mode (LS) and the first mode (SS), and storing the pixel potential (Vp).
Abstract(Chinese):

本发明涉及一种读出CMOS图像传感器的方法。 该方法包括将第一模式（SS）中的像素（Px1）设置并且复位像素（Px1），使得预定电压（V-ref）在光电二极管（Dde）和第一电容（C_low）上设置。 该方法还包括收集降低光电二极管（Dde）上的像素电位（Vp）的电荷载流子。 该方法还包括在第一模式（SS）和第二模式（LS）中读出像素（Px1），并存储像素电位（Vp）。 该方法还包括复位像素（Px1），使得预定电压（V_ref）超过光电二极管（Dde），第一电容（C_low）和第二电容（C_high）。 该方法还包括在第二模式（LS）和第一模式（SS）中读出像素（Px1），并存储像素电位（Vp）。
