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.

Apparatus and method for recognizing pattern data in a mobile terminal

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.
