Abstract: An image processing device receives a multi-spectral image and a panchromatic image of a scene. The device extracts a luminosity subcomponent image from the multi-spectral image and upsamples it to generate a luminosity image of a scale intended for a super-resolved image. For each pixel of the luminosity image, the device performs a series of pixel processing and replacement steps, including extracting a first image patch surrounding the pixel and matching it with a plurality of extracted panchromatic image patches, which are smaller than the first image patch by a ratio of a size of the panchromatic image to a size of the luminosity image. The image processing and replacement of the pixels may be iteratively performed to produce a super-resolved image.

Abstract: A photographic image acquisition device comprising a primary image sensor optically coupled to a primary imaging lens and at least one secondary image sensor optically coupled to a secondary imaging lens, the optical axes of the primary and the secondary lenses set parallel to each other, both image sensors set in the same geometric plane, such that both focal planes arrays receive optical projections of the same scene.
