Embodiment
Referring to Fig. 1, the information carrying means 10 of better embodiment of the present invention, for connect a camera module 20 and
One image analysis apparatus 30.The camera module 20 needs to be tested after being completed, and the content of test generally comprises the camera
The image analysis apparatus 30 is sent to after the shooting image of module 20, the computer of image analysis software is such as installed, carries out image point
Analysis, judges whether the camera module 20 is qualified from analysis result.Such test request camera module 20 can press set bat
Take the photograph parameter shooting image and by the image of shooting at a high speed, without falsehood be sent to the image analysis apparatus 30.Present embodiment
Information carrying means 10 is exactly to be used to connect the camera module 20 and the image analysis apparatus, and the camera module is transmitted between
The information such as 20 acquisition parameters and image.Certainly, the application of the information carrying means 10 is not limited to present embodiment, can also
Information transfer for terminal user.The setting of the acquisition parameters of the camera module 20 is to build the test of the camera module 20
Condition, can be the parameters such as resolution ratio, the vertical sync period of the camera module 20.
The information carrying means 10 includes a first interface 100, one for being used to connect the camera module 20 and is used to connect
Connect 200, cachings 300 of second interface and one and the first interface 100, the second interface of the image analysis apparatus 30
200 and the caching 300 connection processor 400.The processor 400 includes 402, second controllers of first controller
404th, the 3rd controller 406.First controller 402 is used to receive the image analysis apparatus by the second interface 200
