Method and apparatus for scan charge compensation in a digital detector |
摘要 |
A discrete pixel detector is charge compensated in a plurality of scan modes. In each scan mode a different number of rows of the detector is enabled, and signals produced at discrete pixel locations are read at the detector columns. Charges due to parasitic capacitance between the rows and columns are compensated and balanced by applying a compensation voltage to rows not enabled. The number of rows receiving the compensation voltage varies depending upon the number of enabled rows in each scan mode. A single compensation voltage may be used by applying the compensation voltage to a fixed multiple of the number of enabled rows in each scan mode.
