    摘要: 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.

    摘要: A lens shading correction method and apparatus are provided for removing vignetting occurring in digital images due to lens shading. A white image captured by an image pickup device and an image pickup unit is separated into reference white images corresponding to color channels. A vignetting center having a maximum light intensity is estimated in each of the reference white images. Multiple reference segments on each of the reference white images are defined. A lens shading correction value corresponding to each pixel constituting the reference segments are calculated using a corresponding light intensity. A lens shading correction function corresponding to each reference segment is derived using a corresponding lens shading correction value. Vignetting of a general image received in a general image processing mode is removed, using the derived multiple lens shading correction functions.

    摘要: A driving device including a signal controller which receives input image data corresponding to a plurality of frame periods, outputs the input image data during a first sub-frame period of one frame period among the plurality of frame periods, and outputs impulsive data having gray-scales, which are lower than those of the input image data, during a second sub-frame period of the one frame period. The impulsive data in the frame periods in which still images are displayed comprise first gray-scales, and the impulsive data in the frame periods in which moving images are displayed comprise second gray-scales, the second gray-scale being different from the first gray-scales. A data driver converts the input image data to pixel voltages during the first sub-frame period, and converts the impulsive data to impulsive voltages during the second sub-frame period.
