Abstract:
1. Within a digital camera, a method of digital image processing using face detection for achieving a desired image parameter, comprising: identifying a group of pixels that correspond to a face in a foreground region within a digital image taken with flash; determining first initial values of focus of pixels of the group of pixels; determining second initial values of focus of pixels other than pixels of the group of pixels and located within a background region of the digital image; comparing the first and second initial values, respectively, with a desired focus of pixels based on one or more desired values of focus of background region pixels; and determining adjusted values of focus separately for the foreground and background regions based on the comparing of the first and second initial values with a desired focus of pixels based on a desired focus of pixels within said background region, and on a comparison of values of focus corresponding to the first and second initial values.
