Currently, in order to reduce the load of driving IC, within the same period, multi-cam is whole in common application scenarios
General of end can open an image capture module and work, at this point, the image capture module of work will utilize driving IC
Acquired image is handled, and image transmitting is carried out by communication module and CPU, when the image capture module of work is sent out
When raw switching, main needs switch over the image capture module of work, used driving IC and pass through and communicate mould
Block and CPU carry out the route of image transmitting into there is no variations, so that it is total to have reached multiple cameras in multi-cam terminal
The purpose for driving IC and communication module to carry out image procossing and image transmitting with one reduces extra driving IC and leads to
The use for believing module, while reducing cost, reduces the design difficulty of transmission line.
In other embodiments, it can be worked at the same time in multi-cam terminal with multiple images acquisition module, it is desirable that
Driving IC must support the cooperative mode of multiple images acquisition module, and multiple images acquisition module works at the same time worked
Journey is similar with the process that an image capture module works, and a driving IC can handle multiple images acquisition module institute simultaneously at this time
Acquired image, and by the same communication module by image transmitting to CPU.
A kind of circuit structure of multi-cam is present embodiments provided, multiple images acquisition mould is contained in the circuit structure
Block, multiple images acquisition module are all connected on a main body PCB, and the driving IC for image procossing is provided on main body PCB
Chip is handled for the electric signal to each image capture module acquired image, meanwhile, main body PCB also with mainboard
PCB connection, communication module and CPU are provided on mainboard PCB, and the image after processing is passed through communication module and passed by driving IC chip
CPU is transported to, CPU is being shown and stored to the image.The present embodiment, by multiple images acquisition module and main body PCB into
Row connection, realizes the purpose of common drive IC and communication module, to reduce the cost of multi-camera circuit structure, passes through
Sharing for the communication module being connected between multiple cameras and CPU, reduces the design difficulty of telecommunication circuit.
Second embodiment
The present embodiment is that displaying of the multi-camera circuit structure of proposition of the embodiment of the present invention under practical application scene is shown
Example, we are illustrated by taking the dual camera terminal of common a front camera and a rear camera as an example.
Currently, the circuit structure of common dual camera terminal is as shown in figure 4, in Fig. 4, front camera and postposition are imaged
Head is fully functional camera, each camera includes image capture module, main body PCB and driving IC chip,
Driving IC chip point is welded on main body PCB, and the rear of image capture module is arranged in main body PCB, is one with image capture module
Body structure；Each camera will be attached by an individual flexible circuit (FPC) and connector with mainboard PCB,
And it is connect by the communication module on mainboard PCB with the CPU on mainboard PCB, thus by the collected figure of each camera
Image output and storage are carried out as being transferred to CPU.When using circuit structure in Fig. 4, it is desirable that each camera all include
A whole set of complete image capture module, main body PCB and driving IC chip and each camera can all be configured with a set of list
The only FPC communicated with CPU, connector and communication module.
Under normal conditions, the front camera and rear camera of dual camera terminal can't work at the same time, this will
Cause one of camera at work, another camera is in idle state, communication module matched with its and drive
Dynamic IC chip can be in idle state, and which results in the wastes of resource.
Therefore, multi-camera circuit structure according to an embodiment of the present invention improves the existing structure in Fig. 4, obtains
Improved dual camera circuit structure as shown in Figure 5.In this configuration, it is contemplated that under normal conditions, rear camera
Driving IC chip chip performance can be better than front camera, therefore, can remove main body PCB in front camera, driving IC core
Piece and with the mainboard PCB FPC connecting and communication module, front camera at this time only has image collecting function, do not having
Standby image processing function, the image processing function of front camera are handled by the driving IC of rear camera, front end processor
Signal transmission between camera and CPU is completed also by the communication module between rear camera and PCB.
Above-described embodiment is circuit connection diagram when who believes that is to be staggered in front camera and postposition,
In further embodiments, back-to-back setting on the same position of front camera and rear camera at the terminal, it is this
In the case of front camera and rear camera can be made of one formula structure, the main body PCB of rear camera setting is existed
Between front camera and rear camera, the image capture module of this setup front camera and and rear camera
PCB connection do not need using FPC.
Present embodiments provide a kind of dual camera circuit of embodiment of the present invention dual camera terminal in practical applications
The improvement embodiment of structure in the embodiment, is carried out by the main body PCB and driving IC chip of front camera and with CPU
The communication module of signal connection is cancelled, and front camera public security remains image capture module therein, the Image Acquisition mould
Block is connected by FPC with the main body PCB in rear camera, and when preposition my younger brother holds high head work, the image of front camera is adopted
Collect module and the electric signal transmission of acquired image is subjected to image procossing to the driving IC chip in rear camera, uses simultaneously
The communication module crossed between rear camera and CPU transmits the picture signal of front camera, to realize preposition camera shooting
Head rear camera reduces preposition take the photograph by sharing same set of main body PCB, driving IC chip and the purpose of communication module
As the overall cost of head and rear camera, reduce the quantity of communication module, reduces the difficulty of circuit design.
