Patent ID: 8134764

Claim:
An image processing device for improving image quality with a Carry-Save-Add (CSA) accumulator, the image processing device comprising: a CSA accumulator including a first input for receiving a processing signal and a second input for receiving a previous result of the CSA accumulator, the CSA accumulator used for processing a carry-save addition; a first register including an input coupled to the CSA accumulator and an output coupled to the second input of the CSA accumulator; a Carry-Propagate-Adder (CPA) coupled to the first register, the CPA used for processing an addition operation on all carries in a frame during a vertical blank period of a vertical synchronization signal; a second register including an input coupled to the CPA, a control end for receiving the vertical synchronization signal and an output for outputting a result of the CPA; and a central processing unit (CPU) including an input coupled to the second register and an output for outputting an output signal comprising a processed image measurement data.
