  • Patent number: 8873030
    Abstract: A testing device, a detection system, and an automatic detection method thereof are disclosed. The detection system is used for testing an optical capturing module and includes a controlling module and the testing device. The controlling module is electrically connected to the optical capturing module. The testing device includes a base, a fixing unit, a testing unit and a track. The fixing unit is disposed on the base and used for mounting the optical capturing module. The testing unit is used for the optical capturing module to capture a sensing signal. The track is disposed on the base for the testing unit to move along the track. When the testing unit is moving, the optical capturing module is use for capturing a sensing signal curve according to the continuous movement of the test element and the control module determines whether the sensing signal curve is exceed a predetermined value.

  • Patent number: 8665445
    Abstract: A diagnostic system for an optical touch control module and an automatic diagnostic method thereof are disclosed. The diagnostic system is used for testing an optical capturing module of the optical touch control module. The diagnostic system includes a controlling module, a first test element, a second test element, and a rotary fixture. The first and the second test element are disposed on a touch surface for allowing the optical capturing module to capture a first and a second test signal. The rotary fixture is used for contacting to the optical capturing module, wherein the controlling module determines whether an image signal captured by the optical capturing module has the first and the second test signal. If not, the controlling module controls the rotary fixture to rotate the optical capturing module to adjust a capturing direction.

  • Publication number: 20130278940
    Abstract: An optical touch control system and a captured signal adjusting method thereof are disclosed. The optical touch control system includes a base, an image sensor module, and an image processing device. The base has an edge frame. The image sensor module is disposed on the base and used for capturing the edge frame to obtain a testing image signal. The image processing device includes a processing module, a recognition module, and a record module. The processing module is used for executing a testing procedure. The recognition module is used for scanning the testing image signal. When the processing module executes the testing procedure, the recognition module recognizes a coordinate of an edge frame image from the testing image signal. Then the processing module is used for setting the coordinate of the edge frame image as a correct capture coordinate to record in the record module.
