Abstract:
1. A method for capturing a sequence of images with an image sensor that includes a plurality of photosensitive areas that are grouped into a first subset of photosensitive areas and a distinct second subset of photosensitive areas, the method comprising the steps of: (a) capturing a first image; (b) transferring the first image charges from only the first subset of photosensitive areas to a first plurality of storage mechanisms; (c) clearing the first image charges from at least the second subset of photosensitive areas prior to capturing a second image; (d) capturing the second image; (e) transferring the second image charges from only the second subset of photosensitive areas to a second plurality of storage mechanisms; (f) clearing the second image charges from at least the first subset of photosensitive areas prior to capturing, a third image; (g) capturing the third image; (h) reading out the first and second image charges from the first plurality of storage mechanisms and the second plurality of storage mechanisms; and (i) transferring the third image charges, from both the first and second subsets of photosensitive areas to the first and second plurality of storage mechanisms and reading out the third image.
