Abstract: An electronic circuit includes a unit pixel, a first clamp circuit, and a second clamp circuit. The unit pixel outputs a voltage having an output voltage level at a first output voltage level in a first time interval and at a second output voltage level in a second time interval different from the first time interval. The first clamp circuit is configured to clamp the output voltage level from the unit pixel to a first voltage level responsive to the first output voltage level being not greater than the first voltage level in the first time interval. The second clamp circuit is configured to clamp the output voltage level from the unit pixel to a second voltage level responsive to the second output voltage level being not greater than the second voltage level in the second time interval.

Abstract: An image sensor can include a pixel array including a plurality of unit pixels and a row driver arranged in a matrix form that includes a plurality of rows and a plurality of columns. Respective ones of the unit pixels may convent an incident light to an electric signal and may store the electric signal. The row driver may sequentially scan the plurality of rows and may sequentially perform an electronic shutter operation and read-out operation. The electronic shutter operation may reset the stored electric signal in each unit pixel and the read-out operation may read-out the stored electric signal in each unit pixel. The electric shutter operation can include a preliminary shutter operation and a main shutter operation which are sequentially performed on one row. The row driver may overlap the main shutter operation on a first row and the preliminary shutter operation on a second row.

Abstract translation: 图像传感器可以包括包括多个单位像素的像素阵列和以包括多个行和多个列的矩阵形式布置的行驱动器。 单位像素中的各个像素可以将入射光修饰为电信号并且可以存储电信号。 行驱动器可以顺序地扫描多行，并且可以顺序地执行电子快门操作和读出操作。 电子快门操作可以复位每个单位像素中存储的电信号，并且读出操作可以读出每个单位像素中存储的电信号。 电动快门操作可以包括在一行上顺序执行的初步快门操作和主快门操作。 行驱动器可以与第一行上的主快门操作和第二行上的初步快门操作重叠。
