    摘要： An image sensor controls the gain of a pixel signal on a pixel-by-pixel basis and extends a dynamic range while maintaining a S/N ratio at a favorable level. A column unit in an image sensor is independently detects a level of each pixel signal and independently sets a gain for level of the signal. A photoelectric converting region unit has pixels arranged two-dimensionally with a vertical signal line for each pixel column to output each pixel signal. The column unit is on an output side of the vertical signal line. The column unit for each pixel column has a pixel signal level detecting circuit, a programmable gain control, a sample and hold (S/H) circuit. Gain correction is performed according to a result of a detected level of the pixel signal.

    摘要翻译： 图像传感器在逐像素的基础上控制像素信号的增益，并且在保持S / N比在有利水平的同时延伸动态范围。 图像传感器中的列单元独立地检测每个像素信号的电平，并独立地设置信号电平的增益。 光电转换区域单元具有用于每个像素列的垂直信号线二维布置的像素，以输出每个像素信号。 列单元位于垂直信号线的输出侧。 每个像素列的列单元具有像素信号电平检测电路，可编程增益控制，采样和保持（S / H）电路。 根据检测到的像素信号电平的结果进行增益校正。
