Patent ID: 7489814

Claim:
A method of modulating a dynamic range of a plurality of picture elements each containing image information, the method comprising: (a) inputting the plurality of picture elements and extracting, from the image information of a picture element of said plurality of picture elements an intensity level being in a first dynamic range; and (b) for said picture element: (i) defining a surrounding region of picture elements and a remote region of picture elements; (ii) calculating an overall surround intensity using a surround spatial profile, and calculating an overall remote intensity using a remote spatial profile; (ii) selecting at least one adaptation weight-function; and (iii) using said at least one adaptation weight-function, said overall surround intensity and said overall remote intensity, for assigning a new intensity level to said picture element, said new intensity level being in a second dynamic range, thereby modulating the dynamic range of the plurality of picture elements.
