Abstract

A system, device, and method for generating and presenting enhanced image content are disclosed. The enhanced image content presenting system may include a display system receiving enhanced spatial image pixel (SIP) data from an image processor (IP). The IP may be configured to acquire one or more first frequency image pixel (FIP) data, create one or more second FIP data as a function of the at least one first FIP data; determine one or more first enhancement metrics as a function of the one or more second FIP data; and enhance each one of the FIP data as a function of one first enhancement metric or a combination of the first enhancement metrics. In some embodiments, each FIP data may have been formed as a layer of a Laplacian pyramid that results from a deconstruction of pre-enhanced SIP data.
