摘要： The present invention provides a method for efficiently removing noise of an image sensor. To this end, the present invention enables: an area to be divided into an edge area, a sensitivity difference generation area, and a pattern area relative to an input image of a Bayer pattern; and different noise removing methods to be applied according to each of the divided areas. By doing this, noise can be removed efficiently since the noise is adaptively removed in each area. Further, sensitivity differences between Gr and Gb are considered in such a manner that resolution can be improved.

摘要： 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.

摘要： 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.
