Abstract
Spatial resolution can be improved in multi-lens digital cameras. Each lens can have the same or similar field of view, but can be associated with different geometric distortions defining, for example, a magnification at various field of view portions. A final image can be generated based on an initial image captured by each lens. Luminance information from the magnified portions of the initial images can be combined to form final image luminance information. Chrominance information from the initial images can be combined to form final image chrominance information. The final image can be generated based on the final image luminance information and the final image chrominance information.
