    • PROBLEM TO BE SOLVED: To provide a column circuit and a binning circuit for an image sensor that may perform a binning function regardless of a pixel structure and that can serve as an existing column read circuit and a binning circuit.SOLUTION: The present invention comprises: a first column read circuit configured to read data of a first column line and include a fist power source and a first capacitor; and a second column read circuit configured to read data of a second column line and include a second power source and a second capacitor. During a binning mode, data from two or more pixels are output through the first column line and stored in the first capacitor in a first phase, data from two or more pixels are output through the second column line and stored in the second capacitor in a second phase, and charges are shared between the first capacitor and the second capacitor in a third phase.
    • 要解决的问题:提供一种用于图像传感器的列电路和组合电路,其可以执行组合功能而不管像素结构如何,并且可以用作现有的列读取电路和组合电路。 解决方案:本发明包括:第一列读取电路,被配置为读取第一列线的数据,并且包括第一电源和第一电容器; 以及第二列读取电路,被配置为读取第二列线的数据,并且包括第二电源和第二电容器。 在合并模式期间,来自两个或更多个像素的数据通过第一列线输出并以第一相存储在第一电容器中,来自两个或更多个像素的数据通过第二列线输出并存储在第二电容器中 在第三相中,电荷在第一电容器和第二电容器之间共享。 版权所有(C)2012,JPO&INPIT
