Accompanying drawing 10 represents the reality of an optical anti-vibration motor based on controlled mirror head tilt and phase-detection imageing sensor The principle of phase information movement when camera lens is inclined under existing optical anti-vibration mode of operation.The work of phase-detection imageing sensor 2 is former Reason be based on camera lens along optical axis direction move when detect the change of phase information to calculate camera lens in the position of accurate focus, then Camera lens is driven to reach the point rapidly so as to form rapid focus.But, the phase information for detecting can be also caused when deflection lenses It is mobile, for example, when camera lens is along the focusing campaign shift position of optical axisd, the inclined angle of camera lens isθWhen, the detection position of phase place Putting to offset outP（p _L,p _R）Individual location of pixels, and phase place change information is thus worked out to camera lens angle of inclination and the mobile position of focusing The relation table of shifting.
