| 20110025866 | COMPACT LENS OPTICAL SYSTEM AND DIGITAL CAMERA MODULE INCLUDING THE SAME - A dual lens optical system (OS) includes a photographing device, a first OS having a first reflection member and redirecting an optical axis of light representing an image of an object input from a first direction toward the photographing device, and a second OS having a second reflection member, redirecting an optical axis of light representing an image of an object input from a second direction toward the photographing device, and sharing at least one of optical elements of the first OS. The first and second OSs selectively redirect the image light from the first or second direction toward the photographing device. The photographing surface has a first region where the light representing the image of the object input through the first OS is formed, and a second region where light representing the image of the object input through the second OS is formed, have different sizes and are overlapped. | 02-03-2011 |
| 20110085249 | ZOOM LENS SYSTEM AND IMAGE PICKUP APPARATUS - A zoom lens system and an image pickup apparatus including the same are provided. The zoom lens system includes a first lens group having a positive refractive power, a second lens group having a negative refractive power, a third lens group having a positive refractive power, a fourth lens group having a positive refractive power, and a fifth lens group having a positive refractive power, which are arranged in an order from an object side. When zooming is performed from a wide angle position to a telephoto position, the first lens group, the third lens group and the fifth lens group remain fixed and the second lens group and the fourth lens group move. | 04-14-2011 |

| 20100145697 | SIMILAR SPEAKER RECOGNITION METHOD AND SYSTEM USING NONLINEAR ANALYSIS - Disclosed herein is a similar speaker recognition method and system using nonlinear analysis. The recognition method extracts a nonlinear feature of a sound signal through nonlinear analysis of the sound signal and combines the nonlinear feature with a linear feature such as spectrum. The method transforms sound data in a time domain into status vectors in a phase domain and uses a nonlinear time series analysis method capable of representing nonlinear features of the status vectors to extract nonlinear information of a sound. The method can overcome technical limitations of conventional linear algorithms. The recognition method can be applied to sound-related application systems other than speaker recognition systems. | 06-10-2010 |

| 20100097707 | DUAL LENS OPTICAL SYSTEM AND DIGITAL CAMERA MODULE INCLUDING THE SAME - A dual lens optical system including a first optical system and a second optical system includes at least one reflection member to selectively redirect object lights in first and second directions toward a photographing device. The first optical system includes, in order from an object to the photographing device along the optical axis, a first lens group comprising a first reflection member, a second lens group having a negative refractive power, a third lens group having a positive refractive power, a fourth lens group having a positive refractive power, and a fifth lens group having a positive refractive power. The second optical system shares at least one optical element with the first optical system. | 04-22-2010 |
