Abstract: PURPOSE: To attain noise reduction through a filter for filtering only the noise- containing signal sections in digital video signals. CONSTITUTION: Each circuit means is operated by a fuzzy logic and provided with inference circuits (look-up tables) C1 and C2 and digital subtracters S1-S4. Each subtracter has an input terminal and is provided for receiving an individual digital video signal for reporting information concerning the pixel to be processed. The number of circuit means included in a filter 1 depends on the size of an image to be processed, and secondly, depends on the number of directions under the operation of a line operator. While using fuzzy type logic rules, a noise calculation circuit 4 compares trigger levels determined in the circuits C1 and C2 with such a trigger level. Thus, noise contained in the digital video signal are reduced effectively.

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: PURPOSE: To provide high resolution of video and to eliminate the defects of conventional techniques by providing a calculation block which is connected to an input terminal and operated by a fuzzy-logic based processing method and which executes a switch between at least two different interpolation processing methods. CONSTITUTION: For a TV signal scanning converting device 1, luminance/ chrominance signals CFy and CFuv and signals PFy and PFuv corresponding to image fields are inputted to an interface(IF) 2. The IF 2 is operated with a fuzzy logic and supplies TV signals components Xy and Piy to input terminals Pi and X of a filtering block 3. A calculation block CALC1 is operated with a fuzzy logic processing method, receives a luminance component Y and detects the front and motion of a TV signal, while utilizing information in two continuous image fields. On the other hand, an arithmetic block 5 inputs an average parameter, which is calculated based on pixels (Pi , Pj and x) of image fields, to the calculation block CALC1 . A block MAX calculates and outputs the peak value of plural signals to be inputted.

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.
