Detailed Description
The invention will be further described with reference to the drawings and the specific examples.
Referring to fig. 1, the present invention provides a method for implementing camera compatibility, and in particular, to a method for implementing camera compatibility by setting an ep rom i2c address, implementing compatibility of a camera module using the same camera sensor, and solving a problem that the same i2c channel causes device collision due to modifying the i2c address of the camera sensor. The compatibility method of the invention sets two corresponding ep addresses for the two camera modules, and controls the camera modules to send the ep addresses of the camera modules when the camera modules communicate, 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 will be described with reference to the accompanying drawings.
Referring to fig. 1, a flow chart of a method of the present invention for achieving camera compatibility is shown. The method for achieving camera compatibility according to the present invention will be described with reference to fig. 1.
As shown in fig. 1, the method for implementing camera compatibility of the present invention is used for implementing compatibility of a first camera module and a second camera module to share the same camera sensor, and includes the following steps:
step S11 is executed, address information of the camera sensor is issued to a camera module and a camera module; step S12 is then performed;
step S12 is executed, corresponding ep addresses are set for the first camera module and the second camera module, and ep address information sent by the first camera module and the second camera module is received; step S13 is then executed;
step S13 is executed to perform in-place recognition on the first camera module and the second camera module, and return a successful recognition instruction to the in-place camera module.
The compatibility method of the invention enables the first camera module and the second camera module to send the respective ep address information, and the respective ep address information is unique address code, so that equipment conflict can not occur in the communication process, and the compatibility of the two camera modules is realized.
In one embodiment of the present invention, when the address information of the camera sensor is issued, the master control terminal of the mobile phone issues the address information of the camera sensor to the first camera module and the second camera 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 a sensor i2c address: and 0x20, wherein the camera module and the two camera modules receive the address information of the camera sensor, and the camera sensor addresses can be set by the camera module and the two camera modules. However, if the camera sensor address is not compatible with the MASTER when the camera module and the camera modules use the camera sensor address to perform i2c communication, address collision occurs.
Therefore, after the addresses of the camera sensors are set, the first camera module and the second camera module set in the invention set corresponding ep addresses, specifically, the ep address of the first camera module can be set to 0xA0, the ep address of the second camera module can be set to 0xB0, when the first camera module and the second camera module perform i2c communication with the MASTER, the corresponding ep addresses can be issued, and the first camera module and the second camera module are distinguished by using the ep address, so that the problem of collision cannot occur in the same i2c channel, and the compatibility of the camera modules is realized.
In one embodiment of the present invention, when in-place recognition is performed, if one camera module is in place, a successful recognition instruction is returned to the one camera module, and a failure recognition instruction is returned to the two camera modules;
if the two camera modules are in place, an instruction of successful recognition is returned to the two camera modules, and an instruction of failure recognition is returned to the one camera module.
Further, when in-place identification is performed, the main control end of the mobile phone performs in-place identification.
In one embodiment of the present invention, the method further comprises: and controlling the first camera module and the second camera module to issue the corresponding ep addresses.
In one embodiment of the present invention, after an instruction for successful recognition is returned to the in-place camera module, the in-place camera module can call the camera sensor according to the received address information of the camera sensor.
In one 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 the i2c bus.
By utilizing the i2c communication principle, the master equipment end transmits an i2c signal to the slave equipment end, and whether the communication is successful is judged by whether a signal returned by the slave equipment end is correct.
As shown in fig. 2, an in-situ process for the camera module is described below.
MASTER issues a sensor i2c address: 0x20 for one camera module and two camera modules. An ep i2c address for the camera module to change to issue 1 for the camera module: 0xA0, two for camera module to change into 2 for the camera module's ep m i2c address: 0xb0. And when the signal is successfully received, the in-situ module is identified, the camera module is successfully identified 1, and the camera module is failed to identify 2, so that the compatibility of the camera modules 1 and 2 is realized.
As shown in fig. 3, the following describes the bit flow of the two camera modules.
MASTER issues a sensor i2c address: 0x20 for one camera module and two camera modules. An ep i2c address for the camera module to change to issue 1 for the camera module: 0xA0, two for camera module to change into 2 for the camera module's ep m i2c address: 0xb0. And when the signal is successfully received, the in-situ module is identified, the camera module is successfully identified by the in-situ module 2, and the camera module is failed to identify by the in-situ module 1, so that the compatibility of the in-situ module 1 and the in-situ module 2 is realized.
The compatibility method solves the problem that other devices in the same channel collide due to the fact that the camera modifies the camera sensor i2c address in the compatibility problem.
The present invention has been described in detail with reference to the embodiments of the drawings, and those skilled in the art can make various modifications to the invention based on the above description. Accordingly, certain details of the illustrated embodiments are not to be taken as limiting the invention, which is defined by the appended claims.
