Bonjour Yann. So far all of my tests (using Landsat5, Landsat7, IKONOS, QuickBird2 and WorldView2 imagery) indicate that you _need_ to feed the module with 8-bit data. For your interest, there is also a related ticket: <https://trac.osgeo.org/grass/ticket/2048>. My small research on it as an answer in a related question over at GIS@SE: <http://gis.stackexchange.com/questions/39174/how-to-color-balance-false-composites-of-pan-sharpened-landsat-images-in-grass/67319#67319>. So you better rescale, optinally color-balance before sharpening, sharpen and, probably color-rebalance after sharpening.
