Step judges, to determine that this trigger condition triggers other position regulating function in camera terminal, such as terminal stabilization the most simultaneously
Function, it is simple to other position regulating function triggered this trigger condition in time takes appropriate measures, it is to avoid this technology is to CAF
The impact of function.Here by embodiment of the present invention scheme preset the first trigger condition judge, this preset first
Trigger condition is can to trigger other position regulating function corresponding and the trigger condition of CAF function in camera terminal simultaneously.
Trigger condition firstly for scene changes class illustrates, by foregoing it is known that CAF function can be triggered
Scene changes include a variety of, for former embodiment, i.e. light variable or dimmed, the multiple conversion of shooting background, bat
Move before and after taking the photograph object, reference object the change all fully belonging to shooting environmental such as be increased or decreased, for camera terminal
For be perhaps not required to move or change in location etc., therefore, the scene changes embodiment of the above-mentioned type does not interferes with bat

Change, and this first trigger condition preset can carry out self-defined according to different application scenarios, such as, for camera terminal
The different stabilization technology of middle design arranges the first different trigger conditions.
The stabilization technology being currently, there are in camera terminal has multiple, including optical anti-vibration OIS, electronic flutter-proof and photosensitive
Device stabilization etc..
Optical anti-vibration, is not to allow fuselage not tremble, and it is dependent on special camera lens or charge coupled cell CCD photo-sensitive cell
Structure reduce operator to the full extent in use owing to the image that causes of shake is unstable.Implement principle
It is: the gyroscope in camera lens detects the movement of smile, and signal can reach the position calculating needs compensation on microprocessor
Shifting amount, then by compensating lens set, jitter direction and displacement according to camera lens are compensated for, thus effectively overcome because of phase
The image fog that the vibration of machine produces.
Electronic flutter-proof, is primarily referred to as on digital camera using and forces to improve the photosensitive parameter of CCD, add quick operating valve pin simultaneously
The image obtained on CCD is analyzed, then utilizes the stabilization that edge image compensates.
Photoreceptors stabilization, is first to be fixed on by CCD on a support that can move up and down, senses phase by gyroscope
The direction of machine shake and amplitude, then these data are sent to processor and carry out screening, amplifying by sensor, calculate and can support
Disappear the CCD amount of movement shaken.

The data of Hall element calculate the displacement needing to compensate immediately, correct the position of lens group, make camera lens keep and light as far as possible
Axle is vertical.And in CAF function, after also occurring to detect that the change in location of camera lens and/or angle change by gyroscope, it is determined that
Scene changes, thus starts the phenomenon of focusing, and therefore, at this moment OIS function and CAF function are carried out simultaneously, and OIS is to lens group
Reverse calibration so that the picture of sensor output is delayed, will certainly affect the accuracy of CAF, therefore, in this embodiment,
The first default trigger condition can be defined as change in location and/or angle change that the built-in gyroscope of camera terminal detects
Change.
