Description

Technical Field

[0001] The utility model relates to the technical field of CMOS protection structures, and particularly to an object shadow photography accessory structure for a mirrorless digital camera. Background Technique

[0002] Object shadow photography is a special photography method that directly forms an image by projecting an object on a light-sensitive material.

[0003] Previously, materials used for object shadow photography mostly included color and black-and-white photographic papers, scanners, Polaroid papers, color and black-and-white light-sensitive films, etc. There has been no method of directly using the CMOS of a mirrorless digital camera for object shadow photography.

[0004] A mature method of using a mirrorless digital camera to take object shadow photography is to directly place the object to be photographed on the CMOS imaging sensor surface of the mirrorless digital camera, and then use the original electronic shutter of the camera to expose and form an image to obtain an image.

[0005] However, since there are many types of imaging objects placed on the CMOS surface, including liquids, dust, impurity particles and other substances, they may cause wear and damage to the CMOS surface and the protective glass on the surface, and the above various substances are also very likely to enter the body of the mirrorless digital camera, causing damage and failure of mechanical or electronic devices. Therefore, an object shadow photography accessory structure for a mirrorless digital camera is provided. Summary of the Utility Model

[0006] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Simplifications or omissions may be made in this part, as well as in the abstract and the title of the description of this application, to avoid obscuring the purpose of this part, the abstract and the title of the description, and such simplifications or omissions shall not be used to limit the scope of the utility model.

[0007] Therefore, the purpose of the utility model is to provide an object shadow photography accessory structure for a mirrorless digital camera. Through the design of the object shadow holder, a protection structure can be formed between the CMOS surface of the mirrorless digital camera, the camera lens mount and the outside world, avoiding possible wear, pollution, short circuit and other damages to the CMOS and the camera during object shadow photography.

[0014] As a preferred solution of the shadow photography accessory structure of a mirrorless digital camera described in the present utility model, wherein: the cover plate component includes a connection cover connected to the outer side of the protective cover, and a limiting groove adapted to the protective cover is formed in the connection cover.

[0015] As a preferred solution of the shadow photography accessory structure of a mirrorless digital camera described in the present utility model, wherein: the bottom of the connection cover is symmetrically and integrally formed with buckles, and rubber bumps are bonded in the buckles.

[0016] As a preferred solution of the shadow photography accessory structure of a mirrorless digital camera described in the present utility model, wherein: the bottom of the shadow stand is made of a colorless transparent material, and the material is colorless transparent glass or organic glass or plastic material, and the external length and width dimensions of the bottom surface of the shadow stand are slightly smaller than the planar length and width dimensions of the space around the cmos sensor.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. Through the design of the shadow stand, a protection structure can be formed between the cmos surface of the mirrorless digital camera, the lens bayonet of the camera and the outside world. When performing shadow photography, it avoids possible wear, pollution, short circuit and other damages to the cmos and the camera caused by substances such as liquid, dust, impurity particles, etc. Moreover, a rubber pad is connected to the bottom of the shadow stand, which can prevent the shadow stand from directly contacting the cmos surface to a certain extent;

[0019] 2. The buckles are engaged with the outside of the lens bayonet of the camera to fix the position of the connection cover, and then fix the protective cover on the lens bayonet of the camera body, which can effectively prevent the protective cover from shifting under force when placing items on the shadow stand.
