  • Patent number: 7857703
    Abstract: A method for coordinate generation to be implemented using an orientation device includes the steps of: providing at least three reference marks on a target; aiming the orientation device at an initial point on the target, and operating the orientation device such that the sensor is able to capture an image of the target that contains at least one of the reference marks; correlating a coordinate space of the orientation device with a coordinate space of the target; aiming the orientation device at a target point on the target, and operating the orientation device such that the sensor is able to capture an image of the target that contains the reference marks; and determining relative coordinates of the target point with reference to the established coordinate space relation and the captured image. An orientation device that performs the method is also disclosed.

  • Publication number: 20070273646
    Abstract: A pointer positioning device for positioning an aiming point on a display screen of an image display comprises at least one auxiliary point, an image sensor and an optical filter. The auxiliary point is disposed at the peripheral of the display screen for generating a predetermined spectrum. The image sensor receives signals of the predetermined spectrum generated by the auxiliary point. The optical filter is disposed in front of the image sensor for filtering out spectrum outside the predetermined spectrum such that the image sensor can merely sense the signals of the predetermined spectrum, wherein the auxiliary point is utilized as a reference point for correcting an initial setup and positioning the aiming point so as to position the aiming point inside a predetermined range on the display screen. The present invention also provides a pointer positioning method adapted to the pointer positioning device.

  • Publication number: 20070158431
    Abstract: A wireless image capture apparatus includes an image sensor, a backend circuit and a radio frequency module. The image sensor converts captured images into digital signals. Subsequently, the backend circuit performs image processing, data compression and format transformation on the digital signals. The output signals of the backend circuit are series-for-mat signals compatible with the radio frequency module. Thus, wireless signals are outputted by the radio frequency module toward the exterior of the apparatus.
