Fig. 3 is the flow chart of the camera control method of the embodiment of the present invention 1.
Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality
It applies among a range.
Embodiment 1
Referring to Fig. 1, Fig. 2, the present embodiment provides a mobile phone, the mobile phone includes a cam device, the camera dress
It sets including the pcb board 11 in the mobile phone, 13, two one first lens module 12, the second lens module imaging sensors
14, a signal amplifier, a lens motor 15, one are used to drive the motor drive circuit and a transmission bracket of lens motor
17。
First lens module 12 and the second lens module 13 are respectively arranged on the two sides of the pcb board 11, and the first mirror
The shooting direction of head mould group 12 and the second lens module 13 is on the contrary, specifically, the second lens module 13 is set to first on pcb board 11
The another side of the pcb board 11 of 12 position of lens module.
The present embodiment overlaps front camera and rear camera, makes full use of the confined space on pcb board, energy
The space on mobile phone display screen is enough saved, improves screen accounting, and since the position of front camera and rear camera is overlapped,
So that the position of two cameras is closer in the electronic device that front camera and rear camera are connected, be more convenient cabling with
And the typesetting of electronic component, therefore the size of further reduction mobile phone top margin frame, keep mobile phone thinner, volume is smaller.
Imaging sensor 14 is set to the camera lens rear of the first lens module and the second lens module, for acquiring image letter
Number.
Two described image sensors 14 are connect with the signal amplifier, and the signal amplifier and the modulus turn
Parallel operation connection.The imaging sensor of first lens module 12 and the second lens module 13 turns with the signal amplifier and modulus
Parallel operation connection, two imaging sensors share a signal amplifier and digital analog converter and can further save in mobile phone
Space, the size for shortening frame at the top of mobile phone improve screen accounting.
Specifically, when the first lens module works (front camera unlatching), the signal amplifier receives the first mirror
The signal that the corresponding imaging sensor of head mould group is transmitted, and the analog-digital converter will be transferred to after the signal transmitted amplification
Carry out analog-to-digital conversion.Since the first lens module and the second lens module usually only can activate one to carry out work in routine use
Make, therefore two lens modules can make full use of the sky of interior of mobile phone using the same signal amplifier and analog-digital converter
Between, specifically signal amplifier is set between two imaging sensors, the imaging sensor of the first lens module, signal amplification
Device and the imaging sensor of the second lens module are successively overlapped.
The pcb board is equipped with the recess for accommodating imaging sensor, and the thickness so as to be mobile phone further decreases.
The lens motor is connect with the motor drive circuit.The transmission bracket is for adjusting camera lens in lens module
To the distance of imaging sensor.Camera lens 121 in one end of the transmission bracket and the first lens module is fixed, the transmission branch
Camera lens 131 in the other end of frame and the second lens module is fixed, and the support rod 171 of the transmission bracket passes through the pcb board
And two camera lenses are set up on imaging sensor, the lens motor is used to adjust the position of the transmission bracket.
The transmission device of the first lens module of the application and the second lens module sharing lens motor and motor ---
Transmission bracket.A camera lens is fixed at the both ends of the transmission bracket, is the first lens module and the second lens module respectively
Camera lens.When transmission bracket is mobile to one end, the end principle imaging sensor, and the camera lens of the other end is then close to described image
Sensor, and the first lens module and the second lens module under normal conditions only have one it is in running order, so one
Transmission bracket is just able to satisfy the needs of two lens modules.
The cam device of the application can save the space of interior of mobile phone but also saving components, simplify the inside of mobile phone
Structure, so as to reduce manufacturing cost.
Further, referring to fig. 2, the transmission bracket 17 includes two pairs of support rods 171 and identical as support rod quantity
The fixing groove 172 of (4), two support rods in the pair of support rod 171 are relatively arranged on the two sides of imaging sensor, institute
The shape for stating fixing groove matches with the shape of the support rod and is coated between support rod and fixing groove lubricant, the pcb board
The pcb boards 11 of imaging sensor two sides be equipped with through-hole for fixing the fixing groove, the support rod is set to described solid
Determine in slot and vertical with plane locating for pcb board.
A pair of support rods in face of imaging sensor side be equipped with the flank of tooth, the lens motor include one for it is described
The transmission gear 16 of flank engagement.
The transmission gear is set between imaging sensor and support rod, in the center and transmission gear of the support rod
Line is in pcb board institute in the plane.
The lens motor of the application is set on pcb board, and transmission gear and support rod are set between two camera lenses, thus
A set of transmission device be can use to adjust two lens modules, utilize the confined space in mobile phone to the greatest extent.
Referring to Fig. 3, using the cam device of above-mentioned mobile phone, the present embodiment can provide a kind of camera control method, institute
Stating camera control method includes:
Whether step 100, detector lens mould group work, if so then execute step 101, if otherwise executing step 100 again,
Wherein, only one most lens module are in running order between the first lens module and the second lens module.
Step 101 judges whether the first lens module works, and if so then execute step 102, thens follow the steps 104 if not.
Step 102 judges whether to receive the instruction of an increase focal length, if so then execute step 103, if otherwise terminating to flow
Journey.
Step 103, support rod are moved to first direction along fixing groove to increase the camera lens of the first lens module to image and pass
The distance of sensor, then terminates process.
Step 104 judges whether to receive the instruction of a reduction focal length, if so then execute step 105, if otherwise terminating to flow
Journey.
Step 105, support rod are moved to first direction along fixing groove to reduce the camera lens of the second lens module to image and pass
The distance of sensor.
In step 103, when transmission gear is rotated along a second direction, support rod is moved along fixing groove to first direction,
Therefore after receiving the instruction for increasing focal length, the mobile phone control transmission gear rotates a target angle along the second direction
Degree.
The camera structure of the present embodiment mobile phone is reasonable, occupied space significantly reduces, and cooperates camera control
Method processed, mobile terminal can save the use of electronic component, can not only further save component the space occupied, also
It can reduce production cost.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that these
It is merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art is not carrying on the back
Under the premise of from the principle and substance of the present invention, many changes and modifications may be made, but these are changed
Protection scope of the present invention is each fallen with modification.
