Patent ID: 8351739

Claim:
A device for removing mosquito noise, comprising: a buffer, for receiving an input image comprising a pixel matrix, and storing said pixel matrix, wherein said pixel matrix comprises a first matrix and a second matrix, and both said first matrix and said second matrix include a target pixel; a memory, for storing a plurality of coefficients; a strength determining unit, coupled to said buffer and said memory, for detecting a first image complexity of said first matrix and a second complexity of said second pixel matrix, and for selecting a first strength coefficient from said plurality of coefficients stored in the memory according to said first image complexity and said second image complexity; and a noise reduction circuit, for performing noise reduction on the input image and generating an adjusted image; and a blending unit, coupled to the noise reduction circuit and the strength determining unit, for blending an input pixel of said input image and an adjusted pixel of said adjusted image according to said first strength coefficient to generate an output image.
