Description of the invention () The scope of the invention: The present invention relates to a structure of a three-dimensional slide frame * especially a three-dimensional slide frame structure that can provide clear three-dimensional images. Background of the Invention: A stereoscopic slide film of an image captured by a stereo camera having a fixed distance between the left and right lens optical axes. The non-overlapping parts are the left half of the left frame and the right half of the right frame. The distance between objects is different when the horizon of vision is different. When using a stereoscopic slide viewer, the non-overlapping part will affect the horizon due to the incompleteness of the stereoscopic image. In order to solve this problem, a method of shielding the non-overlapping portions of the left and right pictures is generally adopted. The width of the picture frame of the stereoscopic slide frame is smaller than that of the stereoscopic slide film, and the non-overlapping portions are masked. The width of the masked non-overlapping parts varies, which will have the greatest impact on the composite image (it varies with size, position, color contrast, etc.) and makes the left and right composite images shorter. Therefore, the installation of the negative film is for each individual three-dimensional slide film. From the plurality of three-dimensional slide frames with different picture window widths, a 'stereoscopic slide frame with the most suitable screen shielding amount is selected. Therefore, the film image captured by the stereo camera with fixed optical axis type cannot avoid the picture loss after the picture is blocked, and it has the disadvantages that the picture loss increases at close range. On the other hand, a stereo camera with a distance adjustment device between optical axes can adjust the horizon of the left and right lenses, so that parallax can be corrected with the object distance. Therefore, when the film is uniformly installed in the three-dimensional magic with the same window width as that of the film (Please read the precautions on the back before filling this page).

Description of the invention () In theory, there is no need to use a slideshow The film frame covers the outer edges of the left and right frames to obtain the correct stereo effect. However, even if the image of the negative is captured by a stereo camera that adjusts the optical axis distance automatically or manually, it may be necessary to mask the left and right. Picture correction perspective is as follows. For example, if one of the objects captured is located at a closer distance than the main object, the composition of the left and right pictures will be seriously affected. At this time, the outer edges M of the left and right pictures must be shaded to correct the perspective. In the case of excessive parallax correction (when the distance between the optical axes is extremely short), the error generated by the stereo camera that manually adjusts the distance between the optical axes must be corrected. In contrast to the foregoing, the inner edges of the left and right screens must be masked at this time. However, a stereoscopic slide film of an image obtained by a stereo camera having a device for adjusting the distance between optical axes. A very small amount of masking is required, because the photographic results are in a state of excessive parallax correction. Therefore, the appropriate method is to use a slide frame with a screen window width slightly smaller than the film screen width to adjust the frame size. The negative film is sold to cover a part of the daytime surface. However, in the three-dimensional slide frame of the previous example, the position of the negative film is clamped in the frame and adjusted according to the picture window of the film frame. As a result, the positioning operation will be difficult. And it is inaccurate, which is both troublesome and inefficient. To solve the above technical difficulties, the purpose of the present invention is to provide a three-dimensional slide frame structure with easy installation and accurate positioning.
