Embodiment
Below in conjunction with accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Generally exist
The component of the embodiment of the present invention described and illustrated in accompanying drawing can be configured to arrange and design with a variety of herein.Cause
This, the detailed description of the embodiments of the invention to providing in the accompanying drawings is not intended to limit claimed invention below
Scope, but it is merely representative of the selected embodiment of the present invention.Based on embodiments of the invention, those skilled in the art are not doing
The every other embodiment obtained on the premise of going out creative work, belongs to the scope of protection of the invention.
The following examples are illustrated by taking mobile phone as an example, however, technical scheme is not limited to mobile phone, also
It can be used for the electronic equipments such as the desktop computer of tablet personal computer, notebook including camera.
Embodiment 1
Fig. 1 shows a kind of schematic flow sheet of the camera adaptive approach of one embodiment of the present of invention.
The camera adaptive approach that embodiment 1 is related to includes：
Step S110, processor control power supply output module to export predetermined voltage to shooting via energy supply control module
Head module.
For example, for the camera module of mobile phone, typically there are AVDD (analog voltage), IOVDD (digital voltage), DVDD
(digital core voltage) power supply, but its DVDD power supply of different camera modules is variant, general DVDD be 1.0V, 1.05V,
1.1V、1.2V.Thus, for example, the processor (CPU) of mobile phone can make power supply output module export example by energy supply control module
If 1.0V low-voltage is to camera module.
Step S120, the processor communicate with the camera module.
Step S130, if communication failure, the processor is set to control the power supply to export via the energy supply control module
Module exports the follow-up predetermined voltage of higher voltage value to the camera module, is then return to step S120, makes the place
Reason is thought highly of new to communicate with the camera module.
If processor and camera module communication failure in the step s 120, carry output to the voltage of camera module
Height, such as improve to 1.05V, then, make processor attempt to communicate with camera module again.
Step S140, if communicating successfully, the electricity that the processor will communicate when successfully via the energy supply control module
Pressure is set to the supply voltage for the camera module.
More specifically, energy supply control module can use such as I2C interface or GPIO interface.I2C is a standard association
Interface is discussed, is 2 control line interfaces altogether, one is SCL (clock signal), and one is SDA (data-signal).Main equipment (example
Such as the CPU of mobile phone) and the slave unit energy supply control module of output (control power supply) using I2C interface control, master sets first
Preparation send SCL signal to slave unit, can be by SDA by the identification of oneself after slave unit receives the SCL signal that main equipment is sent
ID (slave unit of each I2C interface has an identification id) is sent to main equipment, and main equipment receives the data on SDA signal line
After parsing, if judging that the slave unit (energy supply control module) is the equipment to be communicated, it will continue to send related control
System order；If main equipment thinks that this slave unit (energy supply control module) is not meant to the equipment to be communicated, number can be closed
According to output.
Main equipment (CPU of mobile phone) and slave unit (energy supply control module of control power supply output) are communicated.Allow first
Slave unit controls power supply output module, and to export low voltage value (such as 1.0V), then main equipment and camera module are communicated
(being generally also I2C interface), if communicated successfully, exports (1.0V) magnitude of voltage, calls this corresponding camera module
Driver.
Otherwise, main equipment sends next control instruction to slave unit, makes slave unit control power supply output module output electric
Pressure value (1.05V), main equipment (CPU of mobile phone) go to be communicated with camera module again, if communicated successfully, exported
(1.05V) magnitude of voltage.The control principle that output 1.1V and 1.2V situation is just as.If the predetermined all magnitudes of voltage of output
(4 magnitudes of voltage as escribed above) so that camera module all can not normally work, and that just illustrates that camera module is not pacified
Install or break down.
GPIO (the General Purpose I/O Ports) meanings are general input/output port, generally, are exactly
Some pins, low and high levels can be exported by them or the state-be high level or low electricity of pins is read in by them
It is flat.
When energy supply control module uses GPIO interface, multiple GPIO signals can be used.Such as 3 GPIO can be used to believe
Number, GPIO output low levels or high level, 000,001,010,011,100,101,110,111 can be combined as.
Exported if design 000 is the voltage for representing the output of mobile phone control power supply output module as 0V, 001 for control
1.0V, 010 is control output 1.05V, and 011 is control output 1.10V, and 100 be control output 1.15V, and 101 be control output
1.20V, remaining can analogize or in reserved state.
The processor (CPU) of mobile phone allows this 3 GPIO of energy supply control module to export 001 first, and (power supply output module is defeated
Go out 1.0V), then cell phone processor can go to be communicated (being typically I2C interface) with camera module, if communicated successfully,
Export (1.0V) magnitude of voltage, the driver of camera module corresponding to calling；Otherwise the processor of mobile phone is by power supply mould
3 GPIO signal outputs 010 (power supply output module export 1.05V) of block, this when, cell phone processor was gone and camera again
Module is communicated, if communicated successfully, exports (1.05V) magnitude of voltage, calls the driving of this corresponding camera module
Program；The control principle that output 1.1V and 1.2V situation is just as.If 4 magnitudes of voltage of output so that shooting head mould
Block all can not normally work, then judge that camera module is fitted without or broken down.
According to the camera adaptive approach of the present invention, if processor and camera module communication failure, pass through electricity
Source control module progressively heightens the magnitude of voltage of power supply output module output, different camera modules is matched with this, so as to real
Now adaptive process.Although the example that camera adaptive approach is applied to mobile phone is described above, however, this method
Other electronic equipments with camera are applied equally to, the difference is that the voltage needed for camera may be different.
