DEFINITION

Classification: 257/445

With antiblooming means:

(under subclass 443) Subject matter with means to prevent more than one individual light responsive element from being activated by a very bright spot of light incident on a point of the matrix or array.

(1) Note. The anti-blooming means may drain charge from adjacent individual array elements to some other area, e.g., the substrate. This is known as an overflow drain.
