What is Blooming and Anti Blooming in CCD cameras?

If light impinges on a spot of a CCD-image sensor, the individual "well" (pixel) is filled up with the generated charge carriers. When there is too much light, the well capacity is exceeded, and the additional charges spill into the adjacent "wells" (pixels). This undesirable phenomenon is called blooming, which results in inaccurate data in neighboring pixels, ultimately reducing spatial resolution. Anti-blooming measures are defined as any actions taken to reduce this effect.
