    • The prevent invention discloses a CMOS image sensor, the timing control method and exposure method thereof. The CMOS image sensor includes a pixel array composed of a plurality of pixel lines and a control chip for controlling the pixel array. The control chip controls the pixel lines to expose in the exposure time during one exposure period of each pixel line, and then wait predetermined time after exposure time to output data. In the prevent invention, the exposure time of the CMOS image sensor is separated from the time of outputting data. Therefore, the working mode of the CMOS image sensor can be controlled more flexibly. Furthermore, by adopting the exposure method of controlling the pixel lines in the sub-array of the CMOS image sensor to expose synchronously provided by the present invention, the flash time of the light source is the same as the exposure time of each single sub-array, thereby improving the utilization efficiency of the light source power and ensuring real-time image sampling.
    • 本发明公开了一种CMOS图像传感器,其定时控制方法及其曝光方法。 CMOS图像传感器包括由多个像素线组成的像素阵列和用于控制像素阵列的控制芯片。 控制芯片控制像素线在每个像素线的一个曝光期间的曝光时间内曝光,然后等待曝光时间之后的预定时间输出数据。 在本发明中,CMOS图像传感器的曝光时间与输出数据的时间分离。 因此,可以更灵活地控制CMOS图像传感器的工作模式。 此外,通过采用控制CMOS图像传感器的子阵列中的像素线的曝光方法以由本发明提供的同步曝光,光源的闪光时间与每个单个子像素的曝光时间相同, 从而提高光源功率的利用效率,保证实时图像采样。
