Photographic image acquistion device and method
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.
