Patent Images
1. An image sensor apparatus comprising:
- an array of active pixels to acquire a plurality of frames of image data in respective exposure intervals; and
an image formation processor to receive the plurality of frames of image data from the array of active pixels and to combine the plurality of frames of image data into an output image, including combining a first pixel from a first frame of the plurality of frames of image data with a second pixel from a second frame of the plurality of frames of image data, wherein the first and second pixels are disposed at different pixel positions within the first and second frames, respectively.

Abstract
Multiple scans of a digital integration image sensor are combined to form an output image. The sensor scans or portions thereof may be positionally-shifted relative to one another, and may be acquired in uniform or non-uniform exposure intervals. Selected pixels within at least one of the scans may be excluded from the combination. The scans may also be non-uniformly weighted prior to being combined, with the scan weighting profile corresponding to the scan order.
