1. An image processing method comprising: a) acquiring a main image of a scene; b) determining one or more facial regions in said main image; c) analysing said one or more facial regions to determine if any one of said facial regions includes a defect; d) acquiring a sequence of relatively low resolution images nominally of said scene for a time period not including a time for acquiring said main image; e) determining one or more sets of low resolution facial regions in said sequence of low resolution images; f) analysing said sets of facial regions to determine if any facial regions of a set corresponding to a defective facial region of said main image include a defect; g) combining defect free facial regions of said corresponding set to provide a high quality defect free facial region; and h) correcting at least a portion of any defective facial regions of said main image with image information from a corresponding high quality defect free facial region, wherein said step f) of analysing further comprises: prior to said combining, removing facial regions including faces exceeding an average size of faces in a set of facial regions by a threshold amount from said set of facial regions.
