Embodiment 1

[0021] figure 1 The flow chart of the implementation method of the host external camera provided by Embodiment 1 of the present invention, this embodiment is applicable to the situation where the external camera is connected to the host in a pluggable form for image processing, and the particularly preferred scenario is, On the mobile terminal implemented with the Android (Android) host operating system, plug and unplug the external camera to realize the endoscope. The method can be executed by a device for realizing an external camera of the host computer implemented by software, and the device is configured in a mobile phone such as a mobile terminal.

[0022] The method of this embodiment specifically includes the following steps:

[0023] Step 110, when the host operating system detects that the external camera is plugged and unplugged, it broadcasts the plug-and-plug information of the external camera;

[0024] Step 120, the camera application program receives the broad...

Embodiment 2

[0030] figure 2 It is a flow chart of a method for implementing an external camera of a host provided in Embodiment 2 of the present invention. This embodiment provides a preferred example based on the foregoing embodiments.

[0031] In this embodiment, the interface type of the external camera is Universal Serial Bus (USB for short). Those skilled in the art can understand that the interface type of the external camera can also be provided by the host. Other protocol ports.

[0032] The host operating system in this embodiment takes the Android system as an example, and the kernel used in it is Linux. The function and interface of the setting function provided by the Android system can also realize similar functions in other host operating systems, and the only difference is the name.

[0033] Based on the foregoing, the method of this embodiment specifically includes the following steps:

[0034] Step 210, configure the kernel of the host operating system to support the ...

Embodiment 3

[0063] image 3 It is a schematic structural diagram of a device for realizing an external camera provided by a host computer according to Embodiment 3 of the present invention. The device includes: a plug-in broadcast module 310 , a resource instance operation module 320 and an image processing module 330 .

[0064] Wherein, the plugging broadcast module 310 is used to broadcast the plugging information of the external camera when the host operating system detects the plugging and unplugging of the external camera; the resource instance operation module 320 is used to receive the plugging information of the external camera using the camera application program Broadcasting, through the operation interface of the hardware abstraction layer of the host operating system, generate or release the camera resource instance; the image processing module 330 is used to use the camera application program to call the generated camera resource through the operation interface of the hardware...

Abstract

The embodiment of the invention provides a realizing method and device for an external camera of a host, and a mobile terminal. The method comprises the steps of when a host operation system monitors the condition that the external camera is plugged or unplugged, broadcasting the plugging-unplugging information of the external camera; using a camera application program to receive the broadcasting of the plugging-unplugging information of the external camera, and generating or releasing a camera resource example by the operation interface of a hardware abstraction layer of the host operation system; enabling the camera application program to call the generated camera resource example by the operation interface of the hardware abstraction layer of the host operation system so as to finish an image processing function. The source example of the external camera is realized by software, so the external camera is virtualized to the internal camera of the host, and further the processing function for an image collected by the external camera is realized. As the external camera can be conveniently plugged on or unplugged from the host, so the operation is flexible and convenient, and no extra hardware and software improvement is needed, and the realizing cost is low.

Description

technical field [0001] Embodiments of the present invention relate to computer equipment technology, and in particular to a method and device for implementing an external camera of a host and a mobile terminal. Background technique [0002] Endoscope, also known as endoscope, is a multidisciplinary and general-purpose tool. Its function is to probe deep into curved pipes, to observe parts that cannot be seen directly, and to observe the internal space structure in a sealed cavity. and state, can realize long-distance observation and operation. Industrial videoscopes can realize non-destructive testing without dismantling or destroying the assembly and stopping the operation of the equipment, and are widely used in modern core industries such as aviation, automobiles, ships, electrical, chemical, electric power, gas, atomic energy, civil engineering, etc. each department. [0003] Existing endoscopes are composed of a host and a detection tube. The detection tube is a camer...
