When light conditions are poor, not every pixel is black. But some are very exposed those pixels are called hot pixels. It is possible to detect non black pixels and replace them by a neighbor pixels by using an interpolation technique.

If a correction matrix is trained the sensor could be preproccesed in hardware by for example bilinear or bicubic interpolation.

I think it must be possible to add it to the autoexp software.
