Abstract
An adjustable camera module and an assembly test method therefor. The assembly test method for the adjustable camera module comprises: measuring a static tilt amount between the optical lens sheet group and the photosensitive assembly by performing a defocus curve test on the adjustable camera module; analyzing a static adjusting electric quantity of each adjustment coil of an adjustment coil group according to the static tilt amount; and burning the static adjusting electric quantity required by each adjustment coil so as to reduce process requirements.

1-17. (canceled)
A assembly test method for an adjustable camera module, comprising:
- (a) assembling an optical lens sheet group, an adjustable actuator and a photosensitive assembly to form an adjustable camera module;
- (b) measuring a static tilt amount between the optical lens sheet group and the photosensitive assembly by performing a defocus curve test on the adjustable camera module;
- (c) analyzing a static adjusting electric quantity of each of adjustment coils of an adjustment coil group according to the static tilt amount;
- and
- (d) supplying the static adjusting electric quantity required by each of the adjustment coils to the adjustable camera module;
- and
- (e) measuring an adjusted defocus curve, wherein if the defocus curve is measured after adjustment, and it indicates that the static tilt amount is within an acceptable error range, then the static adjusting electric quantity required by each of the adjustment coils is burned;
- and if a position difference exceeds an acceptable error range, then the steps (b), (c) and (d) are repeated.
A assembly test method for an adjustable camera module, comprising:
- (A) assembling an optical lens sheet group, an adjustable actuator and a photosensitive assembly to form an adjustable camera module;
- (B) measuring dynamic tilt amounts corresponding to the adjustable camera module at different focus positions;
- (C) according to the dynamic tilt amounts, analyzing dynamic adjusting electric quantities required by each of the adjustment coils of the adjustment coil group at the respective focus positions;
- (D) driving the optical lens sheet group to focus, and supplying the dynamic adjusting electric quantity required by each of the adjustment coils corresponding to a focus position to the adjustable camera module;
- and
- (E) measuring an adjusted dynamic tilt amount, and if the adjusted dynamic tilt amount is within an acceptable error range, burning the dynamic adjusting electric quantity required by each of the adjustment coils corresponding to the focus position;
- and if the adjusted dynamic tilt amount exceeds the acceptable error range, repeating the step (B) and the step (C).
