Fig. 3 is a first schematic flow chart of an electric driving method for a camera according to the present invention.
Referring to fig. 3, the present embodiment provides a method for electrically driving a camera, including:
s101: a first instruction is received.
The first instruction may be understood as an instruction for instructing to drive the first camera to power up, and may specifically include an identifier for characterizing the first camera and an action identifier for instructing to execute a power-up action; the first instruction may be in the form of any data capable of implementing the above functions in the field.
S102: and traversing the information listed after the second driving information in the list according to the sequence in the list according to the first instruction.
List, it can be understood that the driving information of different cameras are listed in sequence.
The driving information is used for indicating a driving circuit which needs to be conducted when the corresponding camera is powered on; the driving information includes first driving information of the first camera and second driving information of the second camera, and the second driving information is listed before the first driving information. The driving information can comprise an identification of a driving circuit of the camera, and the driving circuit which needs to be conducted for driving the camera to be electrified can be obtained through obtaining the driving information. The driving information can carry sequence information representing the sequence of the driving information, and the driving information is traversed according to the sequence information, so that the sequential traversal of each driving information can be realized; the driving information is used for indicating the driving circuit which needs to be conducted when the corresponding camera is electrified.

In the field, the MTK platform issues a common template for a search process from the viewpoint of universality. Namely: the software defaults to scanning the list from index 0 (representing the rear camera) in turn, and if the i2c communication is successful, representing the rear camera is powered on successfully, the rest of the list will be scanned continuously until the last one. Then the list continues to be scanned sequentially starting with index 1 (representing the front camera), if the i2c communication is successful, representing the front camera power-up is successful, and the scanning continues until the last end of the list.
From the above description, the drawbacks include: first, two cameras are stopped until the last one is scanned, the number of lists is defined as 16 by default, and if the assembled camera is located at a position closer to the front of the list, redundancy and time consumption are caused. Secondly, after the rear camera is scanned successfully, it is obvious that no other rear camera can continue to be matched, so that it is not necessary to continue scanning, and the continuous scanning still causes time redundancy. Third, for some cameras, the above scanning procedure may also cause interference between the front and back shots, affecting i2c communication.
In addition, the method can also be applied to power-on driving of more than two cameras.
According to the camera power-on driving method provided by the embodiment, information listed behind second driving information in a list containing first driving information is traversed according to the sequence in the list; and when the first driving information is obtained through traversal, driving the corresponding first driving circuit to be conducted according to the first driving information so as to electrify the first camera. When the first camera is driven, traversal from the beginning of the list can be avoided, time consumed by traversal is reduced, power-on efficiency is improved, and fluency of user experience is improved.

So as to implement step S207, setting of the potential, i.e., changing of the index, is performed. In other alternative embodiments, the traversal may not be stopped, but the potential of the first pin may be changed before the subsequent traversal.
It can be understood as follows: after the user triggers the method, the assembled camera can be triggered to be powered on, and after the first camera and the second camera are assembled on the electronic terminal, the first camera and the second camera can be driven to be powered on respectively, so that: the second camera may be understood as a camera powered on in a previous drive, and the first camera may be understood as a camera powered on in a subsequent drive.
