Description of the Invention: [Technical Field] The present invention relates to a stereoscopic digital camera module, and more particularly to an autofocus digital stereo camera module. [Prior Art] With the development of multimedia technology, digital cameras and video cameras are increasingly favored by consumers. When people are pursuing miniaturization of digital cameras and cameras, they are placing higher demands on the image quality of the objects they shoot. People are not only limited to viewing 2D images, but also want to be able to view objects at multiple angles at the same time, that is, they want to see stereoscopic images of objects, and at the same time, mobile phones are increasingly popular with consumers, and mobile phones are also portable. Lightweight and convenient to carry, people hope to capture the stereoscopic image of the scene at any time by installing the digital camera module in the mobile phone. Conventional camera and imaging systems only enable users to obtain 2D images. For 2D images, only a single view is required. It is usually used to place a camera in a fixed position and then record an image of the subject by a film or electronic sensor in the camera. However, human vision is stereoscopic, and the human brain can combine the two images to create an additional depth dimension to produce a stereoscopic image. In recent years, cameras and electronic sensors have been designed so that people pick up two-dimensional images and then recombine to produce a stereoscopic image with a depth element. The conventional stereoscopic imaging system captures the subject separately from different angles by the two cameras to obtain a plurality of two-dimensional images. The two cameras are usually relatively fixed, and when the plurality of two-dimensional images of the object are recombined, Through the positional relationship between the two cameras, the combined image of the plurality of images, that is, the stereoscopic image, can be obtained by 1288561. However, the stereoscopic imaging system requires two camera bodies including a lens group and a sensing component, which is inconvenient to carry, and The system cannot synthesize the multi-image to generate a stereo image while displaying the stereo image, and simultaneously display the stereo image effect to the user, and the distance between the two sensing components cannot be automatically adjusted for the object of different object distances during imaging. It is easy to produce parallax. A multi-eye image sensing device is disclosed in U.S. Patent No. 6,549,650, the entire disclosure of which is incorporated herein by reference. The multi-eye image sensing device can display the three-dimensional image while sensing the image, and adjust the imaging system according to the displayed stereo image to achieve the optimal imaging effect. Please refer to the first figure, which includes two image sensing optics. The system 6701a and 6701b, an image synthesizing device (not shown), is configured to synthesize the multi-image signal of the object sensed by the multi-image sensing device into a stereoscopic image signal, and an image display device (not shown) is used for A stereoscopic image signal synthesized by the image synthesizing device is displayed. The image sensing optical systems 6701a and 6701b are arranged side by side and are separated by a basic pitch L centered on a starting point of 0:1, which respectively include lens groups 6702a and 6702b as charge couplers of the image sensor (Charge Coupled Device, Hereinafter, CCD) 6703a and 6703b, the object 6904 is placed at a position where the distance Oi is Z, and the multi-eye image sensing device adjusts the angle of the LM by changing the distance between the two sensing optical systems 6701a and 6701b. Objects of different distances Z are sensed and the parallax is reduced to zero in this way. The multi-image image sensing device can simultaneously synthesize the multi-image to generate a stereo image and simultaneously view the stereo image of the stereo image in the display device: x: effect to sense the simultaneous imaging system, but only Can pass the size 'inconvenient operation, and the multi-eye image sensing device:: For multi-eye camera, the sigh is the department. The large size of the body is installed in the mobile phone, and it can be used for convenient operation, auto focus, and small size.
