Paper Abstract

The importance of the nonuniformity (NU) correction of solid state image sensor (IS) lies on enhancing the signal-to-noise ration, especially in low-contrast signal detection. There are various methods for NU correction of IS. But some of the traditional methods are complexed in circuit, and difficult to adjust; some are slow at correction rate, and can not satisfy the real time correction requirement. In this paper, a new method for NU correction is introduced, in which the nonuniformity is corrected by using the memory's function conversion efficiency. The chief advantages of this method are: the correction circuit is simpler and easy to adjust; the convertion rate is relatively high (> equals 5MHz); the correction range is wide.
