    摘要: 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.

    摘要: 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.
