| 20100021019 | AUTOMATIC PHOTOGRAPHING METHOD WITH FACE RECOGNITION - An automatic photographing method with face recognition is applied in a camera having a detecting lens and a photographing lens for a user to photograph a target. First, detect a face of the user through the detecting lens, and obtain a plurality of face images of the detected face. Then, capture an image variance of the obtained face images, and photograph the target through a photographing lens when the captured image variance exceeds a photographing starting value. Therefore, during the whole photographing process, photographing can be achieved through determining variations of the face images of the user without pressing the shutter key of the camera, thereby completely preventing handshakes resulted from the pressing action, and thus improving the photographing quality. | 01-28-2010 |

| 20100232513 | VIDEO COMPRESSION CIRCUIT AND METHOD THEREOF - A video compression circuit including a video pre-processor, a macroblock data storage unit and a video processor is provided. When fulfilled by an input video signal, the video pre-processor converts the input video signal to generate a macroblock data. The macroblock data storage unit alternatively and temporally stores the macroblock data generated from the video pre-processor. The video processor alternatively reads the macroblock data stored in the macroblock data storage unit, and compresses the readout macroblock data to an output video signal. | 09-16-2010 |

| 20080298479 | ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING TRANSMITTING AND RECEIVING METHOD AND DEVICE THEREOF - An orthogonal frequency division multiplexing (OFDM) transmitting apparatus including a signal processing unit, a subcarrier orthogonalization processing unit, and a transmitting unit is provided. The signal processing unit divides a received signal into several real parts and several corresponding imaginary parts. The subcarrier orthogonalization processing unit is coupled to the signal processing unit for receiving the real and the imaginary parts of the signal, and for making the real and the imaginary parts respectively carried by a plurality of different and orthogonal subcarriers. The transmitting unit is coupled to the subcarrier orthogonalization processing unit to transmit the subcarriers. | 12-04-2008 |
| 20090221236 | PRE-ENCODING AND PRE-DECODING APPARATUSES AND METHODS THEREOF - A pre-encoding apparatus and a pre-decoding apparatus are provided. The pre-encoding apparatus adopts a cascade structure constituted by a plurality of pre-encoding units and a plurality of interleavers for pre-encoding, and the pre-decoding apparatus adopts a cascade structure constituted by a plurality of pre-decoding units and a plurality of de-interleavers for pre-decoding. Therefore, the pre-decoding apparatus is featured with a lower error rate. Also, each of the pre-decoding units can be alternatively composed of a plurality of low dimensional pre-decoders so that a computation complexity of the pre-decoding apparatus can be reduced accordingly. | 09-03-2009 |
| 20110038250 | ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING TRANSMITTING AND RECEIVING DEVICE - An orthogonal frequency division multiplexing (OFDM) receiving apparatus, including a receiving unit, a subcarrier demodulation unit and a signal output processing unit, is provided. The receiving unit is for receiving an RF signal to generate a set of discrete signals. The subcarrier demodulation unit is coupled to the receiving unit, and used for demodulating a set of discrete signals to obtain a complex signal. The signal output processing unit is coupled to the subcarrier demodulation unit, and used for capturing and outputting real parts of the complex signal. | 02-17-2011 |

| 20100246731 | Method, Apparatus, and Computer Program Product for Decoding Signals in a Wireless Communication Environment - An apparatus for decoding a received plurality of multi-path signals to recover the data content of transmitted signals may include an integrated circuit. The integrated circuit may be configured to generate a logarithm likelihood ratio based on a received plurality of multi-path signals, where the received plurality of multi-path signals is representative of transmitted data content. The integrated circuit may be further configured to arrange coefficients of an expression generated based on the received plurality of multi-path signals and integrate the expression. The integrated circuit may be further configured to divide the integrated expression by prior information. As a result, the integrated circuit may be configured to receive the plurality of multi-path signals and decode the signals via integration. Associated methods and computer program products may also be provided. | 09-30-2010 |
