阅读说明:本技术 复位方法、复位装置、以及应用其的复位系统和像素阵列 (Reset method, reset device, reset system and pixel array using reset device ) 是由 雷述宇 于 2019-06-03 设计创作,主要内容包括:本发明的实施方式提供一种复位方法、复位装置以及应用其的复位系统和像素阵列,该复位方法包括:电荷累积单元用于存储第一电荷,电荷存储单元用于存储第二电荷,其中第一电荷与第二电荷的极性相反,控制所述电荷存储单元获得所述第二电荷;对电荷累积单元进行复位,以将预设数量的第二电荷从电荷存储单元转移至电荷累积单元,并在第二电荷转移过程中向所述电荷存储单元中充电。该复位方法通过从电荷存储单元转移预设数量的与第一电荷极性相反的第二电荷至电荷累积单元,使得第一电荷和第二电荷结合后电荷累积单元的电压变化,从而实现了对复位电荷量的精确控制,提高积分电荷量的准确性,降低复位噪声,提高输出信号质量。(An embodiment of the invention provides a reset method, a reset device, a reset system and a pixel array using the same, wherein the reset method comprises the following steps: the charge accumulation unit is used for storing first charges, the charge storage unit is used for storing second charges, the polarity of the first charges is opposite to that of the second charges, and the charge storage unit is controlled to obtain the second charges; the charge accumulating unit is reset to transfer a preset amount of second charges from the charge storing unit to the charge accumulating unit and to charge the charge storing unit in a second charge transfer process. According to the reset method, the preset number of second charges with the polarity opposite to that of the first charges are transferred from the charge storage unit to the charge accumulation unit, so that the voltage of the charge accumulation unit is changed after the first charges and the second charges are combined, accurate control of the reset charge amount is achieved, accuracy of the integrated charge amount is improved, reset noise is reduced, and output signal quality is improved.)
