Image combining method and apparatus are disclosed. The Image combining method according to the present invention generates an update background image by changing a value of region classification bit in pixel data value of an original background image to a corresponding region classification value. Then, the update background image is displayed on a background region, and a picture image inputted through camera is displayed on a preview region. If a capture instruction is inputted, a digital image corresponding to the displayed update background image and the picture image is generated and stored. According to the present invention, additional format data is not needed when combining images such that an efficient use of memory is possible.

A portable terminal and a method of controlling a shared memory, the portable terminal are disclosed. The portable terminal includes a memory unit, being equipped with at least 2 ports and having a storage block partitioned into partitioned blocks in a quantity of n, and a plurality of processors, reading or writing data by accessing a particular partitioned block through each dedicated port. At least one of the partitioned blocks is assigned to a common storage block, accessible by a processor having an access privilege, and the access privilege is transferred between the plurality of processors. The common storage block can be partitioned into k sub partitioned blocks, which the data type and process to be stored are predetermined. With the present invention, in the case of the common storage block for the plurality of processors, by allowing the partitioned storage blocks to be partitioned again into sub partitioned blocks depending on a type of data to be stored, the data processing/transmission speed and efficiency can be optimized.

A method for detecting color temperature and an apparatus thereof are disclosed. According to the present invention, the apparatus for detecting color temperature converts RGB color information, generated by interpolating an image signal sequentially inputted in units of pixel from an image sensor, to a three-dimensional coordinate value of luminance, R-G color difference information, and B-G color difference information, and then renews the added value per color, if included in a filtering zone corresponding to a characteristic curve of the image sensor Then, an average value per color is generated in units of frame, and the compensation rate per color is determined such that the average value per color becomes identical to each other With the present invention, accurate colors can be displayed by detecting the color temperature of the current light source and correcting the distorted color information.

A flexible BPSK (binary phase shift keying)/QPSK (quadrature phase shift keying) modulator of the wideband code division multiple access system. The flexible modulator includes a first link selecting unit for selecting a modulating type after receiving a signal of a reverse channel, alternately, an I (In-phase) signal and Q (quadrature) signal of a forward channel for which a spread modulation is to execute, a Hadamard spreading unit permits Hadamard code spreading modulation after receiving the I and Q signals from the first link selecting unit, and a spreading means for executing a spread modulation for a pseudo-noise (PN) code of the exchanged I and Q signals. The present invention can reduce the amount of hardware required by controlling a similar parts of the channel in a wideband code division multiple access system, especially a BPSK/QPSK modulation parts, by an external register and a flexible channel structure for joint control between channels. A reduced number of gates, and reduced power consumption, as well as reliability can be increased by the flexible modulator.
