Abstract

The invention provides a method for driving a mobile phone camera. A memory chip is embedded in a mobile phone camera module, and the memory chip stores first initial codes of the mobile phone camera; a mobile phone software system calls the first initial codes and compares the first initial codes with second initial codes stored in the mobile phone software system, and identifies and stores the initial codes to be used. The method for driving a mobile phone camera reduces the workload of software developers, and the plug and play camera is convenient to use by terminal users.

Description

The cell-phone camera head driving method

Technical field

The present invention relates to a kind of using method of communication apparatus, relate in particular to a kind of cell-phone camera head driving method.

Background technology

The job step of mobile phone cam module of the prior art please refer to Fig. 1, and Fig. 1 is the schematic flow sheet of cell-phone camera head driving method in the prior art, may further comprise the steps: step 21: the camera function menu that enters described mobile phone; Step 22: the cell phone software system reads the light sensor chip id number of described mobile phone cam; Step 23: described cell phone software system searches in the memory of described mobile phone and described ID number corresponding setup code according to described ID number; Step 24: whether judgement searches successful, if not, then changes step 25 over to, if then change step 26 over to; Step 25: provide miscue; Step 26: add corresponding setup code, change step 21 over to; Step 27: the register that described setup code is write described mobile phone cam; Step 28: call described setup code, the light sensor chip of the described mobile phone cam of initialization; Step 29: described mobile phone cam operate as normal, described cell phone software system receives camera data.

From above-mentioned steps as can be seen, when described cell phone software system according to described ID number, when in the memory of described mobile phone, searching the setup code failure corresponding with described ID number, then must add new code by the program development personnel is also debugged, therefore when in cell phone system, increasing a new mobile phone cam module, then must write new code and debugging again, very inconvenient, in addition, the mobile phone terminal user also can't independently change novel camera, has limited the use of this function of mobile phone cam plug and play.

Summary of the invention

The problem that the present invention solves is that existing mobile phone cam driver all needs the research staff to write the problem of new setup code with debugging under the situation of changing camera.

To achieve these goals, the invention provides a kind of cell-phone camera head driving method, may further comprise the steps: step 1: be embedded in a memory chip at described mobile phone cam module, described memory chip stored has first setup code of described mobile phone cam; Step 2: the camera function menu that enters described mobile phone; Step 3: the cell phone software system reads the light sensor chip id number of described mobile phone cam; Step 4: described cell phone software system reads first setup code from the memory chip of described mobile phone cam module; Step 5: described cell phone software system searches in the memory of described mobile phone and the described ID number second corresponding setup code according to described ID number, if search successfully, then changes step 6 over to, if search failure, then changes step 9 over to; Step 6: whether the content of the content of more described first setup code and described second setup code is identical, if not, then changes step 7 over to, if then change step 8 over to; Step 7: change to the content of described second setup code identical with the content of described first setup code; Step 8: call described second setup code, the light sensor chip of the described mobile phone cam of initialization changes step 10 over to; Step 9: store and call described first setup code, the light sensor chip of the described mobile phone cam of initialization; Step 10: described mobile phone cam operate as normal, described cell phone software system receives camera data.

Optionally, described mobile phone links to each other with described mobile phone cam module by three interfaces at least, and described three interfaces are respectively commands for controlling interface, data transmission interface and data read interface.

Optionally, also store the effect parameter of described mobile phone cam in the described memory chip.

Owing to adopted technique scheme, compared with prior art, the present invention has the following advantages: cell-phone camera head driving method of the present invention is deposited in the setup code of mobile phone cam self in the memory chip of mobile phone cam in advance, be convenient to the comparison of the setup code of mobile phone EMS memory storage and directly use, thereby reduced software developer's workload, camera can be accomplished plug and play simultaneously, has made things convenient for terminal use's use; In addition, mobile phone cam manufacturer product inline code can be given full play to the professional speciality of each manufacturer, and the code of devise optimum matter is brought into play the function and the effect of camera to greatest extent; At last, owing to compete, can improve constantly the quality of code between the different vendor, use, so just promote the technological progress of industry, form benign cycle in the hope of obtaining the client.

Embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.

Please refer to Fig. 2, Fig. 2 is the schematic flow sheet of cell-phone camera head driving method of the present invention, and as can be seen from Figure 2, cell-phone camera head driving method of the present invention comprises:

Step 11: be embedded in a memory chip at described mobile phone cam module, described memory chip stored has first setup code of described mobile phone cam, also store the effect parameter of described mobile phone cam in the described memory chip, first setup code is for writing in advance, be positioned in the memory, conveniently call, effect parameter then is user's parameters of checking mobile phone cam for convenience, for example pixel etc.; Step 12: the camera function menu that enters described mobile phone;

Step 13: the cell phone software system reads the light sensor chip id number of described mobile phone cam;

Step 14: described cell phone software system reads first setup code from the memory chip of described mobile phone cam module, this first initial code is the setup code of described mobile phone cam;

Step 15: described cell phone software system searches in the memory of described mobile phone and the described ID number second corresponding setup code according to described ID number, and this second setup code is in the numerous setup code that originally was stored in the mobile phone;

Step 16: whether judgement searches successful, if search successfully, then change step 17 over to, if search failure, then change step 20 over to, the standard of searching success or not is whether to have the described light sensor chip id number and the setup code of ID correspondence therewith in the mobile phone memory;

Step 17: whether the content of the content of more described first setup code and described second setup code is identical, if not, then changes step 18 over to, if then change step 19 over to;

Step 18: change to the content of described second setup code identical with the content of described first setup code;

Step 19: call described second setup code, the light sensor chip of the described mobile phone cam of initialization changes step 21 over to;
