ECLIPSE ELIMNATION BY MONITORING THE PIXEL SIGNAL LEVEL |
摘要 |
An anti-eclipse circuit for an imaging sensor monitors the photo signal level output by a pixel to determine whether the photo signal corresponds to the pixel being operated at a saturated state. If so, there is a risk that the pixel may be susceptible to an eclipse distortion. When the pixel is detected as being operated in a saturated state, the anti-eclipse circuit pulls up the reset signal level previously stored in a sample and hold circuit to an appropriate voltage level in order to prevent an eclipse distortion from arising.
