摘要：
When a level of a signal output from a pixel is higher than a comparison level, the signal output from the pixel is converted into a digital signal during a first period by using a first reference signal. If the level of the signal output from the pixel is lower than the comparison level, the signal output from the pixel is converted into a digital signal during a second period that is longer than the first period by using a second reference signal.
