In the filming apparatus of mobile terminal, the camera module circuit plate in optical anti-vibration photographic head module is not
Drive module including optical anti-vibration or do not include that optical anti-vibration drives module and gyro module, and by light
Learning stabilization drives module or optical anti-vibration to drive module and gyro module to be arranged on the master that radiating condition is good
On plate, the most well solve the local pyrexia problem of optical anti-vibration photographic head module, Consumer's Experience sense
Good, the shake angular velocity data accuracy of detection of gyro module is higher simultaneously, the optical anti-vibration of photographic head
Can be good；
Further, since mainboard ground and camera module circuit plate ground separate, the therefore shooting dress of mobile terminal
In putting, optical anti-vibration drives ground connection and at least one image sensing module (such as PDAF image of module
Sensing module) ground connection also separate, thus avoid optical anti-vibration drive module to optical anti-vibration photographic head
The interference of each image sensing module in module, optical anti-vibration drives module can be operated in low-power consumption
Under PWM mode, effectively reducing power consumption, the optical anti-vibration on mainboard drives module and photographic head simultaneously
Image sensing module type selecting on mould-group circuit-board can be more flexible；
Additionally, in the filming apparatus of mobile terminal, optical anti-vibration drives module or optical anti-vibration drive
Module and gyro module are arranged on the mainboard that flexible layout, cabling and arrangement space are big, it is also possible to pole
The earth saves the cabling of camera module circuit plate and arrangement space etc., be conducive to carrying out layout design and
Reduce blind buried via hole technique, improve the reliability of optical anti-vibration photographic head module.
