Solid state image pickup device and signal reading method thereof |
摘要 |
<p>A solid state image pickup device has a drive unit with an all pixel drive mode for reading all pixels in a horizontal direction and a pixel skip drive mode for reading pixels in the horizontal direction by skipping some pixels, and a plurality of read-out systems for reading pixels. In the all pixel drive mode, signals of pixels are divisionally read by the plurality of read-out systems, and in the pixel skip drive mode, signals of pixels are read by one of the plurality of read-out systems. In this manner, in the pixel skip drive mode, the power consumption can be reduced and a difference between output signal levels to be caused by a variation in characteristics of elements of the read-out system can be suppressed. <IMAGE></p> |
