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: PROBLEM TO BE SOLVED: To reduce computing time and energy consumption in a method of processing digital images in devices for acquiring both individual images and image sequences. SOLUTION: The method of processing digital images comprises the steps of: acquiring images in CFA (Color Filter Array) format; and reducing the resolution of the images acquired. The resolution-reduction step processes the images directly in the CFA format. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide an exposure correction method for improving the quality of a digital image acquired with a no-optimal exposure and taking into account the face that regions, which are important from the perceptive or content point of view, exist in the image. SOLUTION: The method, which is applied directly to the image in CFA (Color Filter Array) format, identifies the regions of the image that are most important from the perceptive or content point of view by means of simple statistical measures. The image is then transformed by inverting then response function is such a manner as to optimize the quality of these regions. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a DSC (Digital Still Camera) system capable of reducing the configuration and energy consumption and producing an image with a small loss on a network. SOLUTION: A digital camera includes: a sensor 205 for sensing an image and producing a first signal; a Bayer pattern producer 210 coupled to the sensor and structured to produce a Bayer pattern from the first signal; a splitter 212 that splits the Bayer pattern into separate color channels; a compressor 220 for compressing the color channels into a compressed image; and an output interface 226 for transmitting the compressed image over a communication channel. The digital camera also includes: a color interpolator 214 that is structured to perform a modification on each of the color channels produced by the splitter 212 prior to transmission of the color channels to the compressor 220. A multimedia packer 222 packs multimedia data in a unique format and transmits the result to the output interface 226 to be connected to a wireless network. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To suppress noise affected on a specific area of a field scanned by the unit of lines by replacing a pixel having noise with an average pixel value of a nearby pixel belonging to a prescribed processing window. SOLUTION: A difference calculation circuit calculates a difference Di (D1-D7) between luminance values Xi (X1-X7) of a pixel adjacent to a processing pixel value X of a processing window. Then a Dmax &Dmin detection block identifies a maximum value and a minimum value of a received difference Di. Upon the receipt of the Dmax and Dmin by an adaptive threshold level detection processing block adopting a 1st fuzzy logic, they are referenced as a membership 1 and corresponding values to the threshold levels Th1, Th2 are generated. Then a local adaptive noise smoothing processing block adopting a 2nd fuzzy block generates a set of output values Ki based on the threshold level parameters Th1, Th2 referenced by a membership 2 and generated before. A final filter block generates a pixel Xout as a sum of weighting factors.
