[0030] Currently, videos recorded by mobile phones or cameras are all 2D (two-dimensional) videos. If you need to record 3D (three-dimensional) videos, the phone needs to have multiple cameras or use VR (Virtual Reality) devices like Apple's vision pro or other professional equipment. On the one hand, most mobile phone hardware does not support it, and hardware upgrades are relatively expensive. On the other hand, the wearing experience of VR devices is not good.

[0031] The utility model provides a 3D video recording accessory, see Figure 1 to Figure 2 , is an embodiment of the 3D video recording accessory proposed in this application, and the 3D video recording accessory will be described below in conjunction with specific drawings.

[0032] See also Figure 1 to Figure 2 The 3D video recording accessory includes a main body 1 and two cameras 2. The main body 1 is provided with a MIPI fusion chip and a signal transmission device 12. The MIPI fusion chip is used to transmit the fusion signal to the mobile device 200 through the signal transmission device 12; the two cameras 2 are spaced apart from each other on the main body 1 and are respectively connected to the MIPI fusion chip by telecommunication.

[0033] The technical solution of the utility model is to assist the mobile device 200 that cannot be supported by the existing hardware to complete the recording of 3D video by setting the 3D video recording accessory externally connected to the mobile device 200, with low cost and good effect. Specifically, the 3D video recording accessory includes the main body 1 and two cameras 2 arranged on the main body 1, the two cameras 2 arranged at intervals are RGB color cameras 2, and the interval distance between them simulates the pupil distance of the human eye. The video or picture taken by the two cameras 2 is transmitted to the MIPI fusion chip for processing, and the MIPI fusion chip splices the data of the two cameras 2 together, for example, one camera 2 takes image A, and the other camera 2 takes image B. The image fused and spliced ​​by the MIPI fusion chip is the image data of A+B distributed on the left and right. The fused image data is transmitted to the mobile device 200 through the signal transmission device 12, and can be viewed on the mobile device 200, so as to meet the needs of 3D video recording of some mobile devices 200 that are not supported by some hardware.

[0034] Furthermore, the distance between the two cameras 2 can be adjusted. In order to satisfy users with different pupil distances to have the same video recording and viewing experience, in some embodiments of the present application, the distance between the two cameras 2 can be set to be adjustable, so that users can adjust it according to their own needs, with higher freedom and greater applicability.

[0035] Specifically, the signal transmission device 12 includes a video bridge chip 121 and a signal transmission structure 122. The video bridge chip 121 is electrically connected to the MIPI fusion chip; the signal transmission structure 122 is used to electrically connect to the video bridge chip 121 and the mobile device 200. The data signal after fusion by the MIPI fusion chip is converted into a USB3.0 or USB2.0 signal by the bridge chip in this embodiment, and then transmitted to the mobile device 200 end through the signal transmission structure 122, which conforms to the transmission line category of the existing mobile device 200, so as to be applicable to the existing commonly used mobile devices 200, close to the conventional use of the mobile device 200, and more applicable. Among them, in this embodiment, the signal transmission structure 122 is set as a signal transmission line 122a, which is more stable and practical compared with the wireless transmission structure.

[0036] In addition, as an auxiliary accessory independent of the mobile device 200, the 3D video recording accessory can be powered by its own power supply 13, or it can be powered by the mobile device 200 after being connected to the mobile device 200. When it has its own power supply 13, it does not need to consume the power of the mobile device 200, but its own weight increases and it is not convenient to carry, and the cost increases, and it needs to be charged separately before use. When it does not have its own power supply 13, it can be connected to the mobile device 200 through the power connection line 14 and powered by the mobile device 200. Contrary to its own power supply 13, it has a lighter weight and lower cost, and does not need to be charged separately, but it consumes power when used. The two settings each have their own advantages and disadvantages. Therefore, the present application proposes two implementation methods for selection based on actual needs, both of which can meet usage requirements. In one embodiment, a power supply 13 is further provided in the main body 1, and the power supply 13 is electrically connected to the camera 2, the MIPI fusion chip and the signal transmission device 12; in another embodiment, a power connection line 14 is further provided on the main body 1, which is electrically connected to the camera 2, the MIPI fusion chip and the signal transmission device 12, and the power connection line 14 is used to connect to the mobile device 200.

[0037] In addition, the main body 1 is also provided with a fixing structure 15, and the fixing structure 15 is used to fix to the mobile device 200. The 3D video recording accessory is a structure independent of the mobile device 200, and needs to be separated from the mobile device 200 for independent operation when in use. However, when temporarily stored, if the two cannot be fixed, the placement will be messy and not convenient for carrying. Therefore, the present application also provides the fixing structure 15 on the main body 1, so that the main body 1 can be fixed to the mobile device 200 through the fixing structure 15. On the basis of facilitating storage and carrying, it is also convenient for the handheld mobile device 200 to perform stable shooting through the 3D video recording accessory. Specifically, the fixing structure 15 includes a magnetic structure or a buckle structure.

[0038] The utility model also proposes a 3D video recording mobile device 200 kit, which includes a mobile device 200 and a 3D video recording accessory. The specific structure of the 3D video recording accessory refers to the above embodiment. Since the 3D video recording mobile device 200 kit adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. The signal transmission device 12 of the 3D video recording accessory is connected to the mobile device 200 by telecommunication.

[0039] Specifically, a fixing structure 15 is provided between the mobile device 200 and the 3D video recording accessory, and the fixing structure 15 includes a magnetic structure or a buckle structure. The fixing structure 15 can be provided only on the 3D video recording accessory, or can be provided between the mobile device 200 and the 3D video recording accessory, that is, the magnetic structure is provided between the mobile device 200 and the 3D video recording accessory to enhance the suction force of the two and improve the stability, or the buckle structure is provided on both the mobile device 200 and the 3D video recording accessory to facilitate the setting of the clamping position, so as to avoid the 3D video recording accessory being stuck on the screen surface of the mobile device 200, so as to avoid blocking the screen of the mobile device 200, or even avoiding damaging the screen of the mobile device 200.

[0040] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
