ABSTRACT:
This invention relates to auto variable anti-blooming bias circuits which can automatically vary the anti-blooming bias of the CCD image sensors according to the intensity of light incident thereon. The circuits comprise a DC voltage generation part for receiving signals fed-back from the output terminal of the CCD image sensor and generating DC voltage by averaging the applied signals, an input voltage generation part for receiving DC voltage transmitted from the DC voltage generation part and generating variable input voltage according to the received DC voltage, and an anti-blooming bias generation part for receiving the variable input voltage transmitted from the input voltage generation part and reference voltage and transmitting to the input, terminal of the CCD image sensor as an anti-blooming bias after comparing the two signals.
