Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of Invention 
         [0002]    The present invention relates to a multi-functional electronic device, and more particularly to a portable integrative stereoscopic video multimedia device for personal use. 
         [0003]    2. Related Art 
         [0004]    When viewing an object, two eyes of a human have a stereoscopic sense, because a distance between two pupils of the human eyes is approximately 6-7 cm. When the two eyes view an object, the viewing angles of the two eyes are not completely the same. Although the difference between the two eyes is slight, when it is transmitted to the brain through retinas, the brain has a sense of different distances based on the slight difference, thereby generating the stereoscopic sense. One eye can also see the object, but it is difficult to differentiate the farness and nearness and the distance of the object. According to this principle, for the same image, if two pictures with a slight angle difference are produced or shot by using the viewing angle difference of the two eyes, and then the two human eyes are made to respectively view the two pictures, the brain generates a stereoscopic image through the retinas. Currently, the principle is applied to various stereoscopic image demonstration techniques. However, the conventional stereoscopic image viewing devices have some disadvantages, for example, the technique is complicated, the cost is high, the image viewing effect is not ideal, so it is difficult to popularize and use the stereoscopic image viewing device as a personal product. 
         [0005]    As the electronic technology is developed, a multi-functional electronic product with communication, shooting, recording, displaying, and gaming functions is proposed, for example, a newly proposed portable game console Gizmondo Widescreen having a mobile phone function, which is a revolution to the conventional electronic product. However, most of the electronic video products can display only plane images, and few personal electronic devices through which the eyes may view high-quality stereoscopic images are available. A terminal device having functions of stereoscopic shoot, gaming, communication, projection, business card recognition, global positioning system (GPS) positioning and navigation, plane and stereoscopic display is not available. According to a naked eye stereoscopic image liquid crystal display (LCD) proposed by SHARP in 2004, the inventor of the application designs a new personal stereoscopic video multimedia electronic device.

The driving gear  4041  is engaged with the left driving tooth  4042 , and the micro motor  4040  controls and adjusts an angle of the left camera  200 , so as to adjust an included angle between axial lines of the left camera  200  and the right camera  201 , and to control the left slide base  400  to move on the straight guide rail  402 . A left screw hole  4043  is disposed on the left slide base  400 , and the left driving screw  4031  matching the left screw hole  4043  controls the operation of the moving motor  4030 , so as to adjust the distance between the left camera  200  and the right camera  201 . Similarly, operations of the moving mechanism and the right rotating mechanism of the right camera  201  are the same as those of the left rotating mechanism. 
         [0056]    In the present invention, one or two projection lenses may be used, and the operating principles of the stereoscopic images are respectively as follows. 
         [0057]    For one projection lens, a time difference principle is utilized. During projection, the two left and right image signals are alternately played. During viewing, a synchronous LCD switching spectacle is worn, such that the left and the right eyes respectively view the two image frames with the visual difference, so as to achieve the stereoscopic image effect through the human brain. 
         [0058]    For two projection lenses, a polarized light principle is utilized. During the projection, the two left and right image signals are simultaneously played in different light wave vibration directions, and are projected to a screen capable of maintaining the original light wave vibration directions after reflection. During viewing, a polarized light spectacle is worn, such that the left and the right eyes respectively view the two image frames with the visual difference, so as to achieve the stereoscopic image effect through the human brain. 
         [0059]    In addition to the optical projection system and the projection control and image signal driver, in order to meet the requirements for different display functions and satisfy different demands of people, the naked eye stereoscopic image LCD  5  and the binocular stereoscopic viewing module  3  are disposed in the display part of the present invention.
