## Title
Photography studio with turntable driving mechanism

## Abstract

A photography studio with a turntable driving mechanism is provided. The turntable is driven to start or brake by at least two timing pulleys contacting with the side of the turntable, and the timing pulleys were driven synchronously by another motorized timing pulley through a timing belt. Therefore, at least two indirect contact points are formed between the motorized timing pulley and the turntable to increase the contact friction to avoid sliding when the rotation of the turntable starts or brakes. In addition, a multilayer platform for shooting shadow-free images is proposed, which comprises a thicker transparent glass plate or plastic plate covered with a thinner curved translucent plastic plate and a group of lamps disposed under or behind the multilayer platform.

## Background
FIELD OF THE INVENTION
The present invention generally relates to a photography studio, and more particularly to a photography studio with a turntable driving mechanism.
DESCRIPTION OF THE RELATED ART
In the conventional art for taking a shadow free plane 2D image, the light is projected from the back of a curved surface of a thicker translucent plastic platform (for example larger than 1 cm) capable of bearing the weight of a photographed object to take shadow free images. However, the thicker translucent plastic platform (as illustrated FIG. 1) is difficult to be formed and has a lower light transmittance to have the issues of energy waste and poor result in taking shadow free images.
Furthermore, for taking a shadow free stereoscopic 3D image, the system illustrated in FIG. 2 is used, wherein a motor 1 directly drives, via a connected shaft 2, a transparent or translucent round platter 3 to rotate or brake. In addition, a plurality of rollers 4 is set under the bottom to support the round platter 3, which is embedded into a curved translucent plastic plate 5. However, because the flatness between the curved translucent plastic plate 5 and the round platter 3 is not perfect or the shaft 2 and the rollers 4 under the bottom of the curved translucent plastic plate 5 are also dimly visible, the result of taking shadow free images is worse.
SUMMARY OF THE INVENTION
The present invention is directed to a photography studio or a light box, which may be used for taking a shadow free plane 2D or stereoscopic 3D image, even can get a pure white background, to omit the background removal process. Specifically for a stereoscopic 3D image stitched from a lot of plane 2D images, it saves big time on background removal process once such a photography studio or light box is applied.
The present invention is also directed to taking a shadow free stereoscopic 3D image by using the above mentioned photography studio or light box, which accompanies with a transparent glass round platter, a transparent plastic round platter or a translucent plastic round platter, so as to reduce slippery situation when a turntable driving mechanism drives the round platter to start or brake rotating. Therefore, it is capable of locating each different shooting angles more accurately, and thus the composed stereoscopic 3D image is much smoother.
The present invention provides a multi-layers platform capable of taking a plane 2D image. In such multi-layers platform, a thicker transparent glass plate or plastic plate (for example 5 mm) is used as a base plate, and a curved thinner translucent plastic plate (for example 2 mm), which may be formed by manually bended from a plane plate or directly formed by plastic injection molding, is disposed on the base plate, so as to form a high light transmission multi-layered platform. The curved translucent plastic plate covered on the thicker transparent glass plate or plastic plate can avoid showing the items thereunder, and the thicker transparent glass plate or plastic plate can bear the weight of a photographed object.
In addition, the present invention further provides a turntable driving mechanism for taking a stereoscopic 3D image. In such turntable driving mechanism, a motive source (for example a motor) drives a timing pulley set with at least two timing pulleys by a timing belt or drives a gear set with at least two gears or a large gear to rotate by another small gear. Therefore, the timing pulley set or the gear set contacts a side surface of the transparent glass or plastic round platter with multi-points (at least two points) or a side surface of the large gear, so as to synchronously start or brake the rotation of the round plate or the large gear to avoid sliding, which is seriously caused by that with only one smooth contact point.

The detail structures of the present embodiment are substantially similar to that of the previous embodiment, besides the present embodiment uses a light transmissive large gear 135 to replace the glass round platter 32 of the previous embodiment, and further uses small gears 137, 138 and 139 to replace the timing pulleys 76, 77, 78, 79, 80 and idlers 87, 88 of the previous embodiment. Therefore, the timing belt 81 of the previous embodiment is omitted.
The light transmissive large gear 135 may be a transparent glass large gear, a transparent plastic large gear or a translucent plastic large gear, or may be a combination of a light transmissive round platter and an annular light transmissive plastic large gear fitting around the light transmissive round platter. Herein, a translucent plastic round platter may further use to cover on the light transmissive large gear 135.
In the present embodiment, a motor 140 drives a small gear 137 disposed on an output shaft of a gear chamber 143 to rotate through a gear reducer 141, a coupling 142 and the gear chamber 143, so as to drive the light transmissive large gear 135 to rotate.

In summary, when using the multi-layers platform provided by the present invention for taking a plane 2D image, the transparent glass plate or the transparent plastic plate with a thicker thickness can carry a heavier photographed object and have higher light transmittance. Moreover, the curved translucent plastic plate covering over the transparent glass plate or the transparent plastic plate and having a thinner thickness can be used as a background, so as to avoid the items located under the transparent glass plate or the transparent plastic plate being taken in the image. Therefore, it is not only saving more energy but also obtaining better shadow free result by using the multi-layers platform provided by the present invention for taking a plane 2D image. Furthermore, by further providing light around the photographed object properly, it is able to generate images with benefits such as pure white, shadow free and unnecessary to do background removal and so on. On the contrary, it is unable to carry a heavier photographed object by only using a curved translucent plastic plate with a thinner thickness.
In addition, it is able to further dispose a transparent glass round platter, a transparent plastic round platter or a translucent plastic round platter on the multi-layers platform, and start or brake the rotation of the above mentioned round platter synchronically by the timing pulleys with at least two contact points between the side surface of the round platter and the timing pulleys. Note that during taking a stereoscopic 3D image formerly, it is necessary to spend a lot of times to do background removal before composing the significant amount of plane 2D images generated from different shooting angles into a stereoscopic 3D image file. However, it is able to reduce the issue of slips when the turntable is driven to rotate by using the turntable driving mechanism of the present invention. Therefore, it is able to control the shooting angles more accurately and thus saving a lot of times for doing background removal when using the turntable driving mechanism together with the above mentioned multi-layers platform to take a shadow free stereoscopic 3D image.
Although specific embodiments of the present invention have been described, it will be understood by those of skill in the art that there are other embodiments that are equivalent to the described embodiments. Accordingly, it is to be understood that the invention is not to be limited by the specific illustrated embodiments, but only by the scope of the appended claims.
