Patent ID: 7746390

Claim:
A device for processing pixel array data in a mobile terminal equipped with a digital camera function, the device comprising: an image sensor having (x×y)-sized pixel capacity, the image sensor to convert an optical signal received via a lens into an electric signal, and to generate (x×y)-sized pixel array data, where x is a total number of pixel columns of the image sensor, and y is a total number of pixel rows of the image sensor; and an image signal processor to generate an (X×Y)-sized extended pixel array data area in a data storage area satisfying a predetermined condition of x×n=X and y×n=Y (where n=natural number greater than 1), to receive individual pixel values of the (x×y)-sized pixel array data from the image sensor, to arrange all the pixel values of the (x×y)-sized pixel array data in the (X×Y)-sized extended pixel array data area in the data storage area to be spaced apart from each other by a pixel size of (n−1), to arrange corresponding pixel values obtained by performing an arithmetical operation on corresponding pixel values of (x×y)-sized pixel array data, which are adjacent to remaining pixel areas of the (X×Y)-sized extended pixel array data in the data storage area other than the pixel areas having the pixel values of the (x×y)-sized pixel array data, in the remaining pixel areas, and to output the (X×Y)-sized extended pixel array data in which the pixel values are arranged in the respective pixel areas so that the (X×Y)-sized extended pixel array data can be displayed.
