Abstract: PURPOSE: An apparatus and a method for detecting a pitch of an audio signal in an audio CODEC(COder and DECoder) are provided to expand bandwidth of the audio signal inputted from the audio CODEC, thereby capable of detecting the pitch from the bandwidth expanded signal. CONSTITUTION: A bandwidth expanding member(210) filters inversely the inputted audio signal, performs bandwidth expansion of the inputted audio signal and generates the bandwidth expanded residual signal. A pitch analysis member(230) calculates and mixes autocorrelation functions of time and frequency of the residual signal, and compares an autocorrelation value at the pitch with the autocorrelation value calculated by dividing the pitch calculated from the mixed autocorrelation functions into integer times and detects the point having the most value as an open loop pitch. A pitch correction member(250) corrects the open loop pitch to an average pitch value when the detected open loop pitch escapes from a set range of a previous frame. A pitch quantization member performs quantization of the corrected open loop pitch with a set level and outputs the quantization result.

Abstract: A mobile communication terminal and a message processing method of the terminal are provided to automatically transmit a message which is written while the terminal performs a communication service blocking mode by which a voice call and message transceiving function is blocked, to a receiving place when the communication service blocking mode is canceled, thereby increasing user convenience. A controller performs a communication service blocking mode for blocking a voice call and message transceiving function(S110), and checks whether a user's message input request exists(S120). If so, the controller converts an operational mode of a mobile communication terminal into a message input mode(S130), and receives a message based on user input information(S140). When the message inputting is completed(S150), the controller checks whether a transmission request for the inputted message exists(S160). If so, the controller stores the message in a memory(S170), and checks whether the communication service blocking mode is canceled(S180). If so, the controller automatically transmits the stored message to a receiving place(S190).

Abstract: PURPOSE: An apparatus and a method for discriminating audio signals by bandwidths using plural bandwidths are provided to detect an audio signal of each bandwidth by using plural band-pass filters at an audio CODEC(COder and DECoder), and to analyze the detected audio signal of each bandwidth, thereby capable of discriminating the intensity of a voiced sound. CONSTITUTION: A band-pass filtering member(210) is comprised of five band-pass filters(211-219) having mel-bands and generates five band-pass audio signals through the band-pass filters corresponding to the inputted audio signals. An envelope detecting member(220) receives the band-pass signals and then generates envelop signals corresponding to the bandwidths. Correlation value detectors(231-239) of an autocorrelation value detecting member(230) calculates autocorrelation functions relating to five band-pass signals and four envelop signals. A maximum value detecting member(240) compares the band-pass signals with autocorrelation values of envelop signals, selects and outputs an autocorrelation function having an autocorrelation value which is greater than another autocorrelation value at the corresponding bandwidth. A discriminating member(250) performs quantization of bpvc(band pass voicing strength) values of the bandwidths and converts the values into digital data.

Abstract: PURPOSE: A pre-processing apparatus for recognizing characters of an image signal and a method therefor are provided to judge whether a picture to be recognized is blurred before recognizing characters of the picture. CONSTITUTION: An input unit(10) inputs a picture. An image blurring judging unit(20) classifies the inputted picture into character blocks and background blocks, calculates a mean energy rate of the classified character blocks, compares the calculated mean energy rate with a certain reference value, and judges whether the inputted picture is a blurred picture. If the inputted picture is not the blurred picture, an image binary-coding unit(40) classifies the inputted picture into character blocks and background blocks, compares pixels of the classified character blocks with a pixel reference value, binary-codes the pixels of the character blocks as brightness values of character pixels and background pixels, and binary-codes pixels of the background blocks as brightness values of background pixels.
