Detailed Description
The invention is further described with reference to the following figures and specific examples.
Referring to fig. 1, the present invention provides a method for implementing camera compatibility, and in particular, a method for implementing camera compatibility by setting an Eeprom i2c address, so as to implement compatibility that a camera module uses the same camera sensor, and solve the problem that the same i2c channel may cause device collision due to modification of the i2c address of the camera sensor. The compatible method of the invention sets two corresponding Eeprom addresses for the two camera modules, and controls the camera modules to send the Eeprom addresses of the camera modules when the camera modules communicate with each other, thereby realizing the compatibility of the two camera modules and enabling the two camera modules to share one camera sensor. The method for realizing camera compatibility according to the present invention is described below with reference to the accompanying drawings.
Referring to fig. 1, a flow chart of a method for achieving camera compatibility according to the present invention is shown. The method for realizing camera compatibility according to the present invention is described below with reference to fig. 1.
As shown in fig. 1, the method for realizing camera compatibility of the present invention is used for realizing that one camera module and two camera modules can share the same camera sensor, and the method comprises the following steps:
executing step S11, sending address information of the camera sensor to a first camera supply module and a second camera supply module; then, step S12 is executed;
step S12 is executed, corresponding Eeprom addresses are set for the first camera module and the second camera module, and Eeprom address information sent by the first camera module and the second camera module is received; then, step S13 is executed;
step S13 is executed to perform in-place recognition on the first and second camera modules, and a command of successful recognition is returned to the in-place camera module.
The compatible method of the invention enables the camera module and the camera module to send respective Eeprom address information, and the respective Eeprom address information is a unique address code, so that equipment conflict cannot occur in the communication process, and the compatibility of the two camera modules is realized.
In a specific embodiment of the present invention, when the address information of the camera sensor is sent, the main control terminal of the mobile phone sends the address information of the camera sensor to the first camera supply module and the second camera supply module.
Preferably, as shown in fig. 2 and 3, the MASTER of the mobile phone issues address information of the camera sensor, that is, issues sensor i2c address: 0x20, one for camera module and two for camera module receive the address information of the camera sensor, so that one for camera module and two for camera module can set the same camera sensor address. However, if one camera module and two camera modules use the camera sensor address to communicate with MASTER i2c, the addresses of the camera sensors are incompatible, and address conflict occurs.
Therefore, after the addresses of the camera sensors are set, the corresponding Eeprom addresses are set for the first camera module and the second camera module, specifically, the Eeprom address of the first camera module can be set to 0xA0, the Eeprom address of the second camera module can be set to 0xB0, and when the first camera module and the second camera module communicate with the MASTER in i2c, the corresponding Eeprom addresses can be issued, and the first camera module and the second camera module are distinguished by using the Eeprom addresses, so that the problem of collision cannot occur in the same i2c channel, and the compatibility of the camera modules is realized.
In a specific embodiment of the present invention, when performing in-place recognition, if one camera module is in place, a command of successful recognition is returned to the one camera module, and a command of failed recognition is returned to the two camera modules;
if the two camera modules are in place, an instruction of successful identification is returned to the two camera modules, and an instruction of failed identification is returned to the one camera module.
Further, when in-place identification is carried out, in-place identification is carried out by a main control end of the mobile phone.
In one embodiment of the present invention, the method further comprises: and controlling a camera module and a camera module to issue corresponding Eeprom addresses.
In an embodiment of the present invention, after the instruction of successful recognition is returned to the existing camera module, the existing camera module can call the camera sensor according to the received address information of the camera sensor.
In an embodiment of the present invention, the mobile phone main control terminal is in communication connection with the first camera module and the second camera module through an i2c bus.
By using the i2c communication principle, the master device side sends an i2c signal to the slave device side, and whether the communication is successful is judged according to whether the signal returned by the slave device side is correct.
As shown in fig. 2, an in-place process of the camera module is described below.
The MASTER issues a sensor i2c address: 0x20 for one supply camera module and two supply camera modules. An Eeprom i2c address for the camera module to change to issue 1 for the camera module: 0xA0, and two for the camera module to change to issue 2 for the Eeprom i2c address of the camera module: 0xb 0. The Eeprom receives the i2c signal, and when the signal is successfully received, the identification is carried out on the in-place module, the identification of the camera module is successfully carried out 1, and the identification of the camera module is failed 2, so that the compatibility of the camera module for 1 and 2 is realized.
As shown in fig. 3, the following describes the in-place process of the two camera modules.
The MASTER issues a sensor i2c address: 0x20 for one supply camera module and two supply camera modules. An Eeprom i2c address for the camera module to change to issue 1 for the camera module: 0xA0, the second one for the camera module to change to issue 2 for the Eeprom i2c address of the camera module: 0xb 0. The Eeprom receives the i2c signal, when the signal is successfully received, the in-place module is identified, 2 is used for the camera module to be identified successfully, and 1 is used for the camera module to be identified unsuccessfully, so that the compatibility of 1 and 2 camera modules is realized.
The compatibility method solves the problem that the camera modifies the address of the camera sensor i2c to cause conflict of other devices in the same channel in the compatibility problem.
While the present invention has been described in detail and with reference to the embodiments thereof as illustrated in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments are not to be interpreted as limiting, and the scope of the invention is to be determined by the appended claims.
