Abstract: Disclosed is a technique for processing pixel array data of a mobile terminal with a digital camera function. A device for processing pixel array data includes: an image sensor having (x×y)-sized pixel capacity, converting an optical signal received via a lens into an electric signal, and generating (x×y)-sized pixel array data; and an image signal processor for generating an (X×Y)-sized extended pixel array data area, receiving pixel values of the (x×y)-sized pixel array data from the image sensor, arranging the pixel values of the (x×y)-sized pixel array data in the (X×Y)-sized extended pixel array data area, arranging pixel values obtained by performing an arithmetical operation on pixel values of (x×y)-sized pixel array data, adjacent to remaining pixel areas of the (X×Y)-sized extended pixel array data other than the pixel areas having the pixel values of the (x×y)-sized pixel array data, in the remaining pixel areas, and outputting the (X×Y)-sized extended pixel array data.

Abstract: Disclosed herein is a mobile communication terminal equipped with a camera having an image distortion compensation function which compensates image distortion created by a luminance difference between pixels in the vicinity of a central portion of a pixel array of an image sensor and pixels in the vicinity of an outer portion of a pixel array of the image sensor by detecting a Y-component value of the central pixel of the pixel array of the image sensor and Y-component values of the pixels located diagonally to the central pixel, comparing the Y-component value of the central pixel with the Y-component values of the pixels located diagonally to the central pixel, generating compensation values for compensating signal distortion in each of the pixels located diagonally to the central pixel according to the comparison result, and outputting a distortion compensation command, together with the compensation values, to the ISP (image signal processor).

Abstract: An apparatus and method for processing data using the complex quadrature phase shift keying (CQPSK) is disclosed. The present invention includes plurality of multiplying units for multiplying a long pseudo noise (PN) code with an in-phase pseudo noise and quadrature pseudo noise, and a results of multiplying with a pilot channel, a dedicated control channel, a voice channel, a high-speed data transmission channel, a result multiplied with channels with gain, filtering units for eliminating noise, subtracting and adding units for calculating final result, and in-phase/quadrature channel outputting unit for outputting I-channel/Q-channel. The present invention can improve data processing speed of a radio channel, increase capacity of data processing in radio communication and also can be applicable to various kinds of radio communication devices transceiving voice, media contents and high-speed data at a same time.
