Patent ID: 7619652

Claim:
A frame processing system comprising: an interface inputting a first picture frame from an electronic camera; a picture frame processor reconstructing at least part of the first picture frame into a second picture frame, making a pixelwise correction of brightness; and another interface outputting at least part of the second picture frame to a display, wherein the picture frame processor comprises: an input-end frame buffer holding the first picture frame therein as an input picture frame; an output-end frame buffer holding the second picture frame therein as an output picture frame; a reconstruction table provider providing a reconstruction table having an address to access to an output pixel of the output-end frame buffer and an address, which corresponds to the address to the output pixel, to access to an input pixel of the input-end frame buffer; a brightness correction parameter provider providing a brightness correction parameter table having the address to access to the input pixel of the input-end frame buffer and a brightness correction parameter corresponding to the address to access to the input pixel of the input-end frame buffer; and a processing unit looking up the reconstruction table to obtain the address to access to the input pixel based on the address to access to the output pixel of the output-end frame buffer and looking up the brightness correction parameter table to obtain the brightness correction parameter based on the obtained address to access to the input pixel of the input-end frame buffer, thereby obtaining a pixel data of the input pixel from the input-end frame buffer and applying the obtained brightness correction parameter to correct the brightness of the obtained pixel data.
