Abstract: An image sensor includes a pixel array including at least one active pixel and at least one line-optical black (L-OB) pixel arranged in a matrix including first to nth rows and first to mth columns, the pixel array configured to output a pixel signal and a dark-level offset signal in units of columns during a read-out operation in one of the first to nth rows; a row driver configured to output a selection control signal to the first to nth rows; and an analog-to-digital converter (ADC) block configured to digitize the pixel signal and the dark-level offset signal. In the pixel array, a dark-level offset signal is simultaneously output from an L-OB pixel in another row during the read-out operation in one of the first to nth rows. Here, ‘n’ and ‘m’ each denote an integer that is equal to or greater than ‘2’.

Abstract translation: 图像传感器包括像素阵列，其包括至少一个有源像素和布置在包括第一至第n行和第一至第m列的矩阵中的至少一个线光学黑（L-OB）像素，所述像素阵列被配置为输出像素 在第一到第n行之一的读出操作期间以列为单位的信号和暗电平偏移信号; 行驱动器，被配置为向第一至第n行输出选择控制信号; 以及被配置为数字化像素信号和暗电平偏移信号的模数转换器（ADC）块。 在像素阵列中，在第一至第n行之一的读出操作期间，从另一行中的L-OB像素同时输出暗电平偏移信号。 这里，'n'和'm'分别表示等于或大于'2'的整数。

Abstract: An image sensor is disclosed. The image sensor includes a plurality of pixels, a switch circuit coupled to the pixels and configured to substantially simultaneously output signals output only from pixels having similar characteristics among the pixels in response to a control signal; and a comparison circuit configured to convert the signals output from the switch circuit into digital signals. The pixels having similar characteristics are located across among the plurality of pixels.
