  • Automatic optical inspection method of periodic patterns
    Patent number: 9429527
    Abstract: An automatic optical inspection method for periodic patterns includes defining regular control points in a periodic pattern, forming aligned images surrounded by the control points, obtaining a median image and a deviation image from the aligned images and defining upper- and lower-limit images to form an adaptive model, using the adaptive model to compare each point of all aligned images, defining the point of the aligned image having a gray-scale pixel greater than the upper-limit image or the smaller than the lower-limit image as a defect area. The optical inspection method is applicable for the defect detection of various periodic patterns and users simply need to manually select a first reference point to a fifth reference point from the control points and further select a rectangular range of one of the control points to create an edge image to detect a defect of the periodic pattern.

  • Method and apparatus for providing three-dimensional content
    Patent number: 9185398
    Abstract: A system providing three-dimensional content may include a portable multimedia device that generates a composite video signal from 3D content. The portable multimedia device may also generate a synchronization signal for the composite video signal based on an automatic calibration and/or a manual calibration between the portable multimedia device and a display on which the content is to be displayed. The synchronization signal may be transmitted from the portable multimedia device to the active 3D glasses, so that activation of the 3D glasses may be synchronized with content displayed on the display.
