Abstract
An anti-eclipse circuit of an image pixel includes a clamping circuit for pulling up a voltage of a reset signal output by the pixel and an eclipse detection circuit for controllably coupling the clamping circuit output to the output of the pixel. The clamping circuit includes a source follower transistor and a switching transistor. The eclipse detection circuit includes a comparator that is operated to detect an eclipse condition. The eclipse detection circuit outputs a control signal to cause the switching transistor to conduct only when a eclipse condition is detected while the pixel is outputting a reset signal.
