"A great benefit of the MIG sensors is that the signal can be read-out accurately multiple times (due to Non-Destructive Correlated Double Sampling, NDCDS, ability). This means that one can provide the same image with multiple different ISO values. Thus one can either choose afterwards the best ISO setting or one can use different ISO values in different parts of the image. In the latter case the ISO value in each pixel is chosen e.g. such that the ISO is increased until the exposure value of the pixel exceeds a certain limit. This has also the unforeseen advantage that the amount of bits required in the Analog to Digital Converter (ADC) can be reduced while at the same time the Dynamic Range (DR) of the image can be improved.
If rolling shutter is utilized, which is typically the case in digital cameras, the reading of the signal multiple times with different ISO values bears the disadvantage that more skew is resulted in. However, in Digital Single Lens Reflex (DSLR) cameras mechanical shutter is typically used which means that the images are free of skew. Thus the MIG sensors offer for the DLSRs (and generally for digital cameras equipped with a mechanical shutter) a unique ability to afterwards adjust the ISO settings."
