| Zusammenfassung: | A method for reducing the row noise from complementary metal oxide semiconductor (CMOS) image sensor by using a local offset correction is disclosed. The method operates on sensor with and without a Color Filter Array (CFA) before any interpolation is applied and estimates the local offset by comparing the rows in a local window. The method also reduces the pixel-to-pixel noise while reducing the row noise. |
