  • Publication number: 20130113923
    Abstract: A blind spot detection alert system. The system comprises two image capturing modules, a processing module, a first display module and a second display module. The two image capturing modules capture a right image and a left image respectively. The first display module is disposed on the right of the second display module. The processing module receives the right image and the left image to analyze a car moving direction. When the processing module determines the car moving direction is a right direction, the first display module displays the right image. When the processing module determines the car moving direction is a left direction, the second display module displays the left image. The processing module calculates a distance to a coming car, a moving direction of the coming car and a speed of the coming car according to the image to get an alert message.

  • Publication number: 20130100287
    Abstract: A blind spot detection system and method thereof applicable to a transportation vehicle. The blind spot detection system comprises a plurality of detection modules, a processing module and a display module. When the transportation vehicle moves at a speed less than a predetermined speed or at a stop moving state, each detection module is used to detect a plurality of blind spot images around the transportation vehicle. The processing module is connected to each detection module and used to receive the plurality of blind spot images and execute an image processing for detecting and identifying a moving object in the plurality of blind spot images, and to generate a mark pattern corresponding to the moving object. The display module is connected to the processing module and used to display the plurality of blind spot images and the mark pattern in a blind spot display mode.

  • Publication number: 20120124468
    Abstract: An electronic apparatus having a touch-controlled interface includes a display unit, a touch-controlled unit, and a display interface. The touch-controlled unit is provided on the display unit, while the display interface is arranged on the display unit for showing figures related to files. When the touch-controlled unit is touched, a signal is generated to make the display interface respond. Further, the display interface shows a time scroll bar, and a user may touch different points of the time scroll bar to define a time period, and thus the display interface is made to show the figures of target files accessed in the time period. Furthermore, a display method includes steps of displaying the figures of files via the display interface, touching the time scroll bar on the display interface to define the time period, and displaying the figures of target files accessed in the time period via the display interface.
