Abstract: A panorama photography method and apparatus is provided to inform a use of an optimum photographing position for the next photograph when capturing in succession several adjacent photographs to obtain a combined panorama photograph. In the method, after a first image is captured, a guide image is generated from a predefined section of the first image, and a first edge is detected in the guide image. A preview image is acquired for a second image to be captured, and a second edge is detected in the preview image. The second edge is obtained from a predefined part of the preview image that coincides with the guide image. Based on comparison between the first and second edges, notification data are generated and outputted together with a synthetic image of the guide image and the preview image.

Abstract: Provided is an improved apparatus and method for recognizing pattern data. The method including extracting a high frequency component with Y data from pattern data sensed through a camera equipped in a mobile station to more clearly recognize edge portions. The high frequency component and the Y data are weighted with predetermined weights, and input data is generated using the high frequency component and Y data weighted with the pre-set weights. Accordingly, edge portions of the input data are more clearly defined, thereby increasing a recognition rate of the pattern data.

Abstract: A method and apparatus for auto white balance in a portable terminal is provided. The method includes analyzing a captured image with histograms of red, green, and blue channels and a histogram of a gray channel; determining whether the histogram of the RGB channels and the histogram of the gray channel overlap over a predetermined percentage; measuring each color distribution average value of the RGB channels when the histogram of the RGB channels and the histogram of the gray channel overlap over a predetermined percentage; and performing color temperature correction using the color distribution average value measured in each of the RGB channels.
