    摘要: An image processing method and apparatus capable of easily detecting an edge of an object from an input image, in which the edge is detected using one step, without a pre-processing step, and a complicated trigonometric function is not used for gradient detection. The image processing method includes setting a window within an input image, analyzing the window to determine directions of edges of objects within the image included in the window, detecting edge information including the edge directions, and processing and outputting the window using the edge information.

    摘要: A method for photographing a panoramic picture includes the steps of checking motion of a corresponding photographing apparatus compares currently input images and previous images in real time through a motion estimation technique employing exposure compensation. Respective images constituting a panoramic picture are photographed, and image photography information is checked that includes focus distance and optical magnification to calculate actual photography range distance of the images. A pre-set threshold is set in consideration of a calculated actual photography range distance of the images. The checked motion is confirmed as to whether the pre-set threshold has been reached, and photography time points of the respective images are determined. The respective images are photographed according to a manual mode or an automatic mode at the photography time point of the respective images.

    摘要: Disclosed is color conversion method using a color look-up table. The method includes the steps of: generating a color look-up table using information on the difference of each channel before and after a conversion of each color; and converting the colors using the generated color look-up table. The step of generating the color look-up table includes identifying the maximum difference value among several difference values and generating a first compressed table to initially compress the difference values using the maximum difference value. Further, the step of generating the color look-up table further includes determining, using a predetermined algorithm, whether precedence bits can be removed in the difference values stored in the first compressed table, if yes, removing the corresponding checked bits and storing the converted channel value in a separate auxiliary color table and, if no, storing an index relating to the auxiliary color table as the corresponding difference value, and generating a secondary compressed table that secondarily compresses the initially compressed difference value and adding type information that indicates if information stored as each difference value is the difference value or the index.
