Image sensor

An image sensor includes analog-to-digital conversion circuits that receive pixel signals from column lines, respectively, and convert the pixel signals into first pixel values, respectively. The data buffer clusters respectively correspond to the enable signals transmitted from the timing controller, and output second pixel values. Each data buffer cluster stores, among the first pixel values, first pixel values corresponding to some of the continuously arranged column lines among the column lines, and outputs the stored pixel values as some of the second pixel values among the second pixel values in response to a corresponding enable signal. A digital processing circuit performs digital processing on the second pixel value output from the data buffer cluster. 一种图像传感器包括模数转换电路，其分别从列线接收像素信号，并且将像素信号分别转换为第一像素值。数据缓冲器集群分别对应于从定时控制器传输的使能信号，并且输出第二像素值。每个数据缓冲器集群存储第一像素值当中的与列线当中的连续排列的一些列线对应的第一像素值，并且响应于对应使能信号，将所存储的像素值输出作为第二像素值当中的一些第二像素值。数字处理电路对从数据缓冲器集群输出的第二像素值执行数字处理。
