Temporally aligned exposure bracketing for high dynamic range imaging

An optical imaging system comprising:

• a light aperture to receive incoming light from an external image;
• a color-neutral separation prism having at least three full color light channels generated by one or more color-neutral internal partially-reflective boundaries, each of the internal partially-reflective boundaries adapted to reflect a selected fraction of the incoming light, the prism oriented to receive the incoming light along a first axis and pass a first fraction of the incoming light out a first light channel aligned with the first axis;
• a plurality of image capturing devices corresponding to the at least three light channels, each of the image capturing devices positioned to receive the selected fraction of the incoming light from its corresponding light channel, including a first image capturing device corresponding to the first light channel and first fraction of incoming light;
• wherein the ISO sensitivity of each image capturing device is selected in combination with the respective light fraction to achieve a respective exposure value, including at least a standard exposure value corresponding to the first light channel and first image capturing device, a second exposure value greater than the standard exposure value and corresponding to a second light channel and second image capturing device, and a third exposure value lesser than the standard exposure value and corresponding to a third light channel and third image capturing device, thereby creating at least three temporally aligned bracketed exposures of an image.
