  • Publication number: 20110194764
    Abstract: A method for removing defective pixels using a signal processing scheme with a Bayer pattern, by determining an output value of the inter-channel according to whether or not a difference between a center pixel and an average of neighboring pixels, which have the same color as that of the center pixel, is greater than or equal to a threshold value; and using values of neighboring pixels nearest to a center pixel as an input, obtaining an output value of the cross-channel by finding a median value among a median value of vertical and horizontal lines including the center pixel, a median value of diagonal lines including the center pixel, and a value of the center pixel. Then, a defective pixel is removed, through the use of the output value of the inter-channel, the output value of the cross-channel, and the value of the center pixel.

  • Publication number: 20110188774
    Abstract: An image generating apparatus and method for emphasizing an edge, based on image characteristics by extracting an edge region from an input original image, and an edge gain indicating a degree for emphasizing the edge region and an edge threshold indicating a degree of complexity between pixels are calculated for each of a plurality of image regions of the original image. The extracted edge region is combined with the calculated edge gain. Thresholding is performed by adjusting the calculated edge threshold for the edge region combined with the edge gain, and the thresholding-applied edge region is combined with the original image to output a final image. By adaptively adjusting an edge gain and an edge threshold for a portion where an edge needs to be emphasized and the other portions in an image having multiple image characteristics, both edge emphasis and noise cancellation can be achieved together.

  • Patent number: 7856176
    Abstract: A method and apparatus for compensating hand-trembling of a camera with reduced time required for capture compensated images. The method may include: calculating exposure time proper for preventing hand-trembling using an AE (Automatic Exposure) algorithm during an image-capturing standby mode; executing image-capturing multiple times depending on the exposure time at the time of inputting a photographing signal through a photographing button, and detecting the amount of hand-trembling at each time of image-capturing. The storing of images can be selected by a preset number of required images from the captured images as resultant images, the images being sequentially stored from an image having a lowest amount of hand-trembling as a resultant image, whereby an image with reduced hand-trembling can be obtained.
