摘要： A circuit and a method for controlling current consumed in a slave device and an I2C interface circuit are provided to prevent registers from unnecessarily operating in a power-down mode so as to reduce current consumption. A circuit of controlling current consumed in a slave device includes a main operating unit(50) and an I2C interface circuit(80). The main operating unit operates in response to a master clock signal and is converted to a power-down mode in response to a power-down signal. The I2C interface circuits communicates with the main operating unit and a master device through I2C protocol and includes a clock controller(70), a first register unit(61) and a second register unit(62). The clock controller receives the master clock signal and enables or disables the master clock signal to generate a power-down control signal in response to the power-down signal. The first register unit receives the power-down control signal as a clock signal and performs a read/write operation. The second register unit performs a read/write operation in response to the master clock signal.

摘要： A Huffman decoding method and a recording medium storing a Huffman decoding program are provided to decrease the number of clock cycles by denormalizing pair mode symbols based on a limit bit flag, a sign bit flag, and a state flag. A pair of symbols having first and second normalized symbols are obtained from a codeword of an input bit stream by using a selected Huffman table(501,503). When a previously stored state flag in the Huffman table has a first state value, the first and second symbols are denormalized, so that a final pair of symbols are obtained(505-515). The final symbols include first and second denormalized symbols. The first denormalized symbol is obtained based on a sign flag and a limit bit flag for the first symbol which are previously stored in the selected Huffman table. The second denormalized symbol is obtained based on the sign flag and the limit bit flag for the second symbol which are previously stored in the selected Huffman table.

摘要： A color interpolation method and apparatus considering grid noise and an edge direction are provided to operate parameters by different algorithms according to the condition of direction information by using edge direction information, thereby preventing the generation of wrong color around a detailed edge portion, suppressing the generation of a zipper-shaped artifact around the edge portion, and removing the grid noise even in applying a new color interpolation method. A color interpolation method considering grid noise and an edge direction comprises the following steps of: setting a grid noise coefficient(900); operating a grid noise offset by using the preset grid noise coefficient(902); extracting only pixel values irrespective of R, G, B(Red, Green, Blue) values from a Bayer pattern image and operating edge direction information(904,906); determining the condition of the operated edge direction information out of preset conditions(908,912); and operating a color interpolation parameter based on a color interpolation parameter operation algorithm related to the determined edge direction information condition(910,914,916). Each of the plural preset conditions is related to the color interpolation parameter operation algorithm. The grid noise offset is used as the parameter of the color interpolation parameter operation algorithm corresponding to each condition.

摘要： A system, a method and a recording medium for performing synchronization of output data generated in an asynchronous dual camera are provided to perform synchronization by buffering the output data of the dual camera through two inner memories each assigned to the dual camera, thereby implementing a three dimensional video system even when vertical sync signals, each transmitted from two cameras of the dual camera, are inconsistent with each other. First and second cameras(301,302) respectively generate output data. Two inner memories(303,304) respectively buffer the output data. A control block(306) synchronizes the output data according to vertical sync signals each transmitted from the first and second cameras. If the number of clocks between the vertical sync signals is larger than capacity of the inner memories, an external memory(305) stores the output data. The control block synchronizes the output data by controlling the inner memories and the external memory according to whether the vertical sync signals are consistent or not.
