Description

Technical Field

[0001] The utility model belongs to the technical field of accessories for photography and videography, and particularly relates to a multi-directional stretch curtain. Background Art

[0002] With social progress and improved living standards, people's demands for a higher quality of life are steadily increasing. As China's film and television and multimedia industries mature and stabilize, along with the continuous innovation of mobile phone photography and the increasing demand for image quality, image processing and video production have gradually become popular and accessible to the general public. This requires extensive keying technology, which presupposes the use of a green background during filming. Previously, this green background was typically a simple green cloth hung on the wall, making it difficult to carry and install, resulting in certain limitations in its use. Currently available retractable, one-piece, foldable screens only have one vertical side that can be retracted into the housing. Therefore, objects on the ground cannot be fully covered by the background during use. For example, Chinese utility model patent CN216133286 U, "A Green Cloth Floor Screen," features a screen that stretches in only one direction, providing only a view of the backing cloth and not the ground background, as objects would be partially outside the screen. Therefore, developing a multi-directional stretch screen that overcomes these limitations is crucial. Utility Model Content
