Problems solved by technology

[0005] Although virtual camera technology can support the use of multiple virtual cameras, the use of virtual cameras in the prior art also has the following defects: on the one hand, users who use virtual cameras need to additionally install corresponding virtual camera software on the terminal, which is relatively difficult to operate. On the other hand, because the virtual camera software can support multipl...

Embodiment 1

[0049] In this embodiment, there are two camera service users, camera service user A and camera service user B; camera service user A and camera service user B respectively create and initialize their own corresponding shared memory at the beginning; Service consumer B sends the request first.

[0050] The method for realizing camera resource sharing in this embodiment is as follows: image 3 shown, including the following steps:

[0051] Steps 301-302: camera service user A creates and initializes shared memory A, and camera service user B creates and initializes shared memory B;

[0052] In practical applications, there is no fixed order for the creation of these two shared memories.

[0053] Step 303: The camera service user B sends a camera service request to the camera service providing module, and the request carries the name of the shared memory B.

[0054] Steps 304a-304b: After receiving the camera service request, the camera service provider module starts the came...

Embodiment 2

[0065] In this embodiment, there are two camera service users, camera service user A and camera service user B; camera service user A and camera service user B respectively create and initialize their own corresponding Shared memory; camera service user A sends a request first.

[0066] The method for realizing camera resource sharing in this embodiment is as follows: Figure 4 shown, including the following steps:

[0067] Step 401: Camera service user A creates and initializes shared memory A.

[0068] Step 402: The camera service user A sends a camera service request to the camera service providing module, and the request carries the name of the shared memory A.

[0069] Steps 403a-403b: After receiving the camera service request, the camera service provider module starts the camera and obtains the video data collected by the current camera; the camera service user A reads the written video data from the shared memory A in a loop;

[0070] Here, steps 403a and 403b are o...

Embodiment 3

[0079] In this embodiment, there are two camera service users, camera service user A and camera service user B; camera service user A and camera service user B send requests at the same time. The numbering of the steps in this embodiment is only for the convenience of description, and does not limit the order in which the two cameras serve users.

[0080] The method for realizing camera resource sharing in this embodiment is as follows: Figure 5 shown, including the following steps:

[0081] Steps 501-502: camera service user A creates and initializes shared memory A, and camera service user B creates and initializes shared memory B;

[0082] Steps 503-504: Camera service user A and camera service user B respectively send camera service requests to the camera service provider module, and the requests carry names of shared memory A and shared memory B respectively.

[0083] Steps 505a to 505b: After receiving the camera service request, the camera service provider module sta...

Abstract

The invention discloses a method for achieving camera resource sharing, which comprises the following steps that: each camera service user creates and initializes a self-corresponding shared memory respectively; and the camera service user needing a camera sends a camera service request, and a camera service providing module writes currently-acquired camera video data into a corresponding shared memory according to the name of the shared memory carried in the request. The invention also discloses a system for achieving the camera resource sharing at the same time, and by adopting the method and the system, the camera resource sharing can be achieved in a simple mode.

Description

technical field [0001] The present invention relates to camera technology, in particular to a method and system for realizing camera resource sharing. Background technique [0002] With the rapid development of network communication technology and multimedia transmission technology, more and more people conduct conversations, communicate, and transmit data, pictures, audio and video information through the network. During the conversation between the two communication parties, in order to allow the other party to see themselves, the user can install a camera on the local terminal, and the camera collects images of the user's current environment and converts them into video data, and then sends the collected video data to The peer for the session. Obviously, the use of the camera plays an important role when using this communication method. [0003] At present, the camera installed on the terminal can be controlled and used by different software inside the terminal, or diff...
