Description
Technical Field
The invention relates to the technical field of electronic products comprising cameras, in particular to a camera self-adaption method, a camera self-adaption device and electronic equipment.
Background
Modern day life has become increasingly more and more ubiquitous with electronic devices such as tablet computers, smart phones, portable notebooks, desktop computers, etc., which are typically equipped with one or more cameras.
When only the same camera sensor is adopted, the voltage required by the camera module is fixed and is directly configured into a fixed voltage value in software; if several different camera sensors are used, but the voltage values required by the sensors are the same, the fixed voltage values can be directly configured in software to meet the voltage required by the camera sensors to work.
However, when the electronic apparatus includes a plurality of cameras, voltages required for the plurality of camera modules may be different. In addition, even when the electronic device has only one camera, since the camera modules may be supplied by different manufacturers, different voltages may be required between the camera modules supplied by different manufacturers.
If several different camera sensors are used and the voltage values required by the sensors are different, then for a platform integrating a camera power supply, a PMIC (power management integrated circuit) chip of the platform can be configured to output different voltage values to meet the voltage required by the operation of the camera sensors.
However, for a platform without a power supply for integrating the camera operation, it is necessary to satisfy the voltage required for the camera operation by adding an external circuit. Because the voltage output by the external circuit is generally a fixed voltage value, and different camera sensors may need sensors with different voltage values, only one sensor can be matched with a circuit with a voltage value output, so that the storage, supply, installation and other aspects of materials are more complicated, and errors are easy to occur.

In view of the above problems, the present invention provides a camera adaptation method, a camera adaptation apparatus, and an electronic device that are compatible with various camera modules.
One embodiment of the present invention provides a camera adaptive method, including:

In the above-mentioned camera adaptive method, the power control module adopts an I2C interface.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The following embodiment is described by taking a mobile phone as an example, however, the technical solution of the present invention is not limited to the mobile phone, and can also be used for electronic devices such as a tablet computer, a notebook computer, a desktop computer including a camera, and the like.
Example 1
Fig. 1 shows a flowchart of a camera adaptation method according to an embodiment of the present invention.
The camera adaptive method according to embodiment 1 includes:
in step S110, the processor controls the power output module via the power control module to output a predetermined voltage to the camera module.
For example, although there are AVDD (analog voltage), IOVDD (digital voltage), and DVDD (digital core voltage) power supplies for camera modules of a mobile phone, DVDD power supplies for different camera modules are different, and DVDD power supplies are generally 1.0V, 1.05V, 1.1V, and 1.2V. Thus, for example, a processor (CPU) of the mobile phone may cause the power output module to output a low voltage of, for example, 1.0V to the camera module through the power control module.
Step S120, the processor communicates with the camera module.
Step S130, if the communication fails, the processor controls the power output module to output a subsequent predetermined voltage with a higher voltage value to the camera module via the power control module, and then returns to step S120 to enable the processor to communicate with the camera module again.
If the processor fails to communicate with the camera module in step S120, the voltage output to the camera module is increased, for example, to 1.05V, and then the processor is caused to attempt to communicate with the camera module again.
In step S140, if the communication is successful, the processor sets the voltage at the time of successful communication as the power supply voltage for the camera module via the power control module.
More specifically, the power control module may employ, for example, an I2C interface or a GPIO interface. I2C is a standard protocol interface, for a total of 2 control line interfaces, one is SCL (clock signal) and one is SDA (data signal). If the master device (for example, a CPU of a mobile phone) and the slave device (a power control module controlling power output) are controlled by using the I2C interface, the master device first sends an SCL signal to the slave device, the slave device receives the SCL signal sent by the master device, and then sends its own identification ID (one identification ID is provided for each slave device of the I2C interface) to the master device through the SDA, and the master device receives data analysis on the SDA signal line, and then determines that the slave device (the power control module) is a device to be communicated, and then continues to send a related control command; if the master device considers this slave device (power control module) not to be the device to communicate, the data output will be turned off.
The master device (CPU of the mobile phone) communicates with the slave device (power control module that controls the power output). The slave device is first made to control the power output module to output a low voltage value (e.g. 1.0V), then the master device and the camera module communicate (I2C interface is also common), if the communication is successful, the (1.0V) voltage value is output, and the corresponding driver of the camera module is called.
Otherwise, the master device sends the next control instruction to the slave device, the slave device controls the power output module to output the voltage value (1.05V), the master device (the CPU of the mobile phone) communicates with the camera module, and if the communication is successful, the voltage value (1.05V) is output. The same control principle is applied to the case of outputting 1.1V and 1.2V. If all the preset voltage values (for example, the 4 voltage values) are output, so that the camera module cannot normally work, the camera module is not installed or fails.
GPIO (General Purpose I/O Ports) means General Purpose input/output Ports, colloquially, pins through which high and low levels can be output or through which the status of the pin-whether high or low-can be read.
When the power control module adopts a GPIO interface, a plurality of GPIO signals can be used. For example, 3 GPIO signals may be used, which output a low level or a high level, and may be combined to 000, 001, 010, 011, 100, 101, 110, 111.
If the design 000 represents that the voltage output by the mobile phone control power supply output module is 0V, 001 is control output 1.0V, 010 is control output 1.05V, 011 is control output 1.10V, 100 is control output 1.15V, 101 is control output 1.20V, and the rest can be analogized or in a reserved state.
The processor (CPU) of the mobile phone firstly lets the 3 GPIO outputs 001 of the power control module (the power output module outputs 1.0V), and then the mobile phone processor communicates with the camera module (usually, an I2C interface), and if the communication is successful, outputs a (1.0V) voltage value and calls a corresponding driver of the camera module; otherwise, the processor of the mobile phone enables 3 GPIO signals of the power control module to output 010 (the power output module outputs 1.05V), and at this time, the processor of the mobile phone communicates with the camera module, and if the communication is successful, a voltage value of (1.05V) is output, and a corresponding driving program of the camera module is called; the same control principle is applied to the case of outputting 1.1V and 1.2V. If the 4 output voltage values enable the camera module not to work normally, the camera module is judged to be not installed or to be in fault.
According to the camera self-adaption method, if the communication between the processor and the camera module fails, the power control module gradually increases the voltage value output by the power output module so as to match different camera modules, and therefore the self-adaption process is achieved. Although the example of the camera adaptation method applied to the mobile phone is described above, the method is also applicable to other electronic devices with a camera, except that the voltage required by the camera may be different.
