Abstract | The present invention relates to an image sensor, and more specifically, to a technique capable of quickly controlling automatic exposure. An embodiment of the present invention includes: a pixel array including a plurality of pixels, and summing voltage values of floating diffusion regions of the respective pixels and outputting the summed voltage values to a bottom node; and an output drive unit that controls the exposure control signal by comparing the voltage value of the bottom node with a preset reference voltage.
本发明涉及一种图像感测器,更具体地,涉及一种能够快速控制自动曝光(Auto Exposure)的技术。这种本发明的实施例包括:像素阵列,其包括多个像素,且合计各个像素的浮动扩散区域的电压值并输出至底部节点;输出驱动部,其通过比较底部节点的电压值与预先设定的基准电压来控制曝光控制信号。 |
