Patent ID: 8564841

Claim:
A method for improving graininess in an image during an ICC profile construction, said method comprising: switching a control operation between a first controller and a second controller utilizing a switching control strategy based on a color space region that requires a graininess minimization in order to thereafter modify a CMYK value associated with a color profile of an image; constructing a destination ICC profile utilizing said modified CMYK value associated with said color profile based on a current state of a rendering device; constructing said destination ICC profile utilizing a rendering device model; defining a recruiting set including a plurality of LAB nodes and computing said CMYK value with respect to said plurality of LAB nodes in said recruiting set utilizing a gray component replacement profile; designating a threshold value associated with said recruiting set in order to thereafter determine a candidate set including at least one candidate node by detecting a color in said candidate set that are closer to a color in said recruiting set; and comparing said candidate node with said threshold node in order to initiate said switching strategy and constructing said destination ICC profile that reduces graininess with respect to said image, thereby reducing graininess and improving smoothness with respect to said image.
