    Abstract: PROBLEM TO BE SOLVED: To provide a method for preserving picture detail and applying filter processing to noise from complicated image files. SOLUTION: A filter is provided for a digital camera includes image sensors sensitive to light, a color filter placed over sensitive elements of the sensors and patterned according to a Bayer mosaic pattern layout, an interpolation algorithm joining together the digital information provided by differently colored adjacent pixels in the Bayer pattern. The filter (10) is adaptive and includes a noise level computation block (26) thus removing noise while simultaneously preserving picture detail.

    Abstract: A method of filtering and an image filter (10) is disclosed. The filter is provided for a digital camera including image sensors sensitive to light, a color filter placed over sensitive elements of the sensors and patterned according to a Bayer mosaic pattern layout and an interpolation algorithm joining together the digital information provided by differently colored adjacent pixels in said Bayer pattern. The filter (10) is adaptive and includes a noise level computation block (26) for operating directly on a said Bayer pattern data set of for each color channel thus removing noise while simultaneously preserving picture detail.
