20110091079 | FACIAL IMAGE RECOGNITION SYSTEM FOR A DRIVER OF A VEHICLE - A facial image recognition system for a driver of a vehicle includes an image capturing unit, an image processing unit, and a warning unit. The image capturing unit is used for capturing facial images of the driver. The image processing unit is electrically coupled to the image capturing unit, has installed therein a facial frame selecting and position correcting method and an identification comparison algorithm, and receives the facial images of the driver from the image capturing unit. The warning unit is electrically coupled to the image processing unit, and emits a warning signal when the image processing unit determines that an identification of the driver has changed. | 04-21-2011 |

20100053320 | OBJECT POSITION DETECTION DEVICE AND METHOD THEREOF - The present invention discloses a fast object position detection device and a method thereof, particularly to a detection device and a method thereof which can directly apply to various image systems. The device of the present invention mainly comprises an image capturing system that captures images within the regions defined by the user, and an image processing unit determining the position of an object and obtaining related information. In the method of the present invention, a captured image is converted into 1-D distance-axis signal information; a differential value of the 1-D distance-axis signal information is used to determine a position of an object; and a difference of the 1-D distance-axis signal information of at least two adjacent time points is used to determine an approaching status of an object. | 03-04-2010 |
20100321174 | Vehicular collision warning system - A vehicular collision warning system comprises at least one image capture device capturing images of blind spots, a processing unit receiving the images of blind spots from the image capture device, and at least one alert device. The processing unit identifies at least one barrier from the images and calculates the speed and transverse displacement of the barrier according to the positional change with respect to time. The processing unit presets at least one attention area on the image, estimates whether the barrier will appear in the attention area, sends out an alert-triggering signal to trigger the alert devices to generate sound, light, or pictures to warn the driver early. Cooperating with the speed sensor, brake system and turn light system, the vehicular collision warning system can trigger different alert signals according to the grading of danger to actively warn the driver early. | 12-23-2010 |
20110026771 | Obstacle determination system and method implemented through utilizing bird's-eye-view images - A technology of determining obstacles around a vehicle through utilizing bird's-eye-view images; wherein, a plurality of image fetching devices disposed in various positions of said vehicle fetch a plurality of images around said vehicle, said images of two adjacent regions contain at least an overlapped region; an image processor transforms said images into said respective independent bird's-eye-view images; and an obstacle detection unit compares said overlapped region in said independent bird's-eye-view images of two adjacent regions, so as to obtain their correlations, and existence of said obstacle is determined based on said correlations. Moreover, a correspondence table is set up containing a set of space transformation information based on vehicle driving condition information. Therefore, a surrounding bird's-eye-view image of an appropriate visual angle can be produced quickly and a position of said obstacle is marked on said surrounding bird's-eye-view image. | 02-03-2011 |

20130054086 | Adjusting Method and System of Intelligent Vehicle Imaging Device - An adjusting method and an adjusting system of an intelligent vehicle imaging device are provided, wherein a real feature point for comparison is disposed in a monitoring area around a vehicle. A camera captures images around the vehicle. The images are transmitted to the controller and displayed on a touch display panel. The controller performs image processing on the images and the real feature point, and compares the real feature point with position data of predetermined feature points, and generates a bird's-eye view image. If the images are captured, the bird's-eye view image is rotated and scaled after conversion according to a predetermined position and a predetermined proportion and then is located on a stitched image and outputted. A blind spot area size or a lane departure parameter is selected through the touch display panel, and the stitched image is adjusted through the touch display panel. | 02-28-2013 |

20110019718 | Spread Spectrum Clock Generator and Method for Adjusting Spread Amount - A spread spectrum clock generator includes a triangular modulator, a delta sigma modulator, a frequency divider, and a phase lock loop. The triangular modulator generates a digital modulation signal, representing a decimal, according to a digital parallel signal, in which the spread amount is in proportion to the digital parallel signal. The delta sigma modulator, electrically connected to the triangular modulator, generates a divider divisor, including the decimal and an integer, according to the digital modulation signal. The frequency divider divides the frequency of the output signal clock according to the divider divisor to generate a divided clock signal, in which the frequency of the divided clock signal is substantially equal to a quotient result from dividing the frequency of the output clock signal with the divider divisor. The phase lock loop adjusts the frequency of the output clock signal according to the divided clock signal and a reference clock signal. | 01-27-2011 |
