Embodiment 1

[0035] Reference figure 2 , image 3 , Figure 4 , A method for a computer to receive input video data from a mobile phone with a camera, the method comprising the following steps:

[0036] (1) The mobile phone 1 and the computer are connected through a data line;

[0037] (2) The computer starts the video function of the video application program 3. The operating system scans the computer's hardware port and sends out video capture information through the application program interface 4.

[0038] (3) The virtual camera 2 searches and captures the video capture information. The virtual camera device 2 establishes a connection between the operating system and the camera 7 of the mobile phone through the virtual camera driver 5 and the micro driver 6:

[0039] (3.1) The image engine (GDI) module 8 reads the video capture signal, and the image engine module 8 uses the I / O manager module 9 to call the routines of the microdrive 6 and the video port, and issues mode read commands;

Abstract

The invention relates to a method for using computer to receive the video data input by the camera mobile phone, and relative system, wherein said method comprises: (1), connecting the mobile phone and the computer via data line; (2), the computer starts the video function of video application program, the operation system scans the hardware port of computer, and sending the video catch information via the application program interface; (3), the virtual camera device searches and catches the video catch information; (4), the computer checks the working condition of mobile phone if meets the data transmission; (5), if meets, the mobile phone enters into stepping state, to obtain the JPEG compressed code flow data, to be sent to the buffer region of image processing module; (6), the image processing module demands the data of buffer region, to transform the JPEG compressed code flow data into bit document to be caught and displayed by the video application program. The invention can transmit the video data to the computer, without writing fixed driving program into the mobile phone.

Description

(1) Technical field [0001] The invention relates to a method for a computer to receive input video data from a mobile phone with a camera, and a system for applying the mobile phone camera to computer video chat or video monitoring. (2) Background technology [0002] Smart phones have more and more powerful functions, which can provide new functions that cannot be achieved by voice communication phones in the past. Among them, the development of camera phones has become a new hot spot. In order to make the mobile phone more competitive and realize the value-added of new functions, we hope that the continuous shooting function provided by the mobile phone camera can provide the same functions as the ordinary camera and realize the alternative camera phone camera used for video chat software. [0003] Based on the camera phone, the camera function is developed for the Windows operating system platform, which can replace the existing ordinary camera in the market and can be directly...
