Abstract
An image processing apparatus for use in a display system comprises a display device for viewing image, and a geometric transformation module that is configured to precondition said image data with geometric transformations to thereby compensate for characteristics of the display system. The geometric transformation module may include a spatial transformation module for redefining spatial relationships between image pixels, an alignment and rotation correction module for repositioning image pixels, a focus correction module for correcting image defocus, a distortion correction module for correcting image distortions, and a multi-frame correlation module for performing motion-compensated frame rate conversion.
Claims34
An image processing apparatus for receiving bitstream data and processing said bitstream data to provide video stream image data to a display device, comprising:
- a display input processor (DIP) coupled to a databus, said DIP comprising an input data connector and a first plurality of processing modules configured to receive bitstream data input and reconstruct said input to generate DIP outputs;
- a display output processor (DOP) coupled to said databus, said DOP comprising a second plurality of processing modules configured to process said DIP outputs for generating DOP outputs, said second plurality comprising a geometric transformation (GT) module and a post GT filtering module;
- and
- a buffer memory, coupled to said databus, configured to store said DIP outputs and said DOP outputs, and to provide said video stream image data to said display device.
An apparatus configured for processing bitstream data to form video stream image data for use in a display system, comprising:
- a display device, coupled to said display system, for viewing image data;
- a geometric transformation GT module coupled to said display device, said GT module configured to precondition said bitstream data using geometric transformations to compensate for characteristics of said display device;
- and
- a temporal gamma processing TGP module coupled to said display device, said TGP module configured to independently determine an output intensity value for each color component output to said display device.
