Abstract:
1. A portable digital camera device having no photographic film, comprising: (a) an integral flash for providing illumination during image acquisition; (b) a digital image capturing apparatus including one or more image sensors for capturing a main image including a face, and for acquiring one or more reference images at least approximately of said same scene as the main image including said face; (c) a face filter for correcting a face defect within the main image based on analysis of at least one reference image; (d) a dedicated hardware subsystem which is provided reference image data directly from at least one of the one or more image sensors; (e) a main system memory which receives raw image data and metadata as implemented by the dedicated hardware subsystem; and (f) wherein the main system memory is configured to receive metadata that comprises one or more identified face defect areas within the main image; and (g) a subsampling module for changing the degree of said subsampling is determined based on a complexity of calculation for said filter.
