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 |
