Abstract
An auto stabilization method and a photographing apparatus using the same are provided. The photographing apparatus having the auto stabilization function includes a voice coil motor actuator (VCMA) to move a photographing element. In the generation of hand tremor, the photographing apparatus controls compensating of the hand tremor. Because one or more dynamic characteristics according to a structure of the VCMA is considered, saturation or delay of displacement of the VCMA is avoided, and a clearer image is provided.
Claims25
A method of auto stabilization of a photographing apparatus, the method comprising:
- generating a driving element control signal to drive a driving element to compensate for a vibration caused due to hand tremor according to one or more dynamic characteristics of a driving element which moves a photographing element with respect to a reference;
- adding a movement compensation signal of the driving element to control displacement of the driving element to the control signal;
- and
- outputting the control signal including the movement compensation signal to the driving element.
A photographing apparatus, comprising:
- a photographing element to photograph an image;
- a driving unit on which the photographing element is mounted, to move the photographing element;
- and
- a controller to generate a driving unit control signal according to one or more dynamic characteristics of the driving unit to compensate for vibration caused due to hand tremor, and to add a driving unit movement compensation signal to control displacement of the driving unit to the driving unit control signal and output the driving unit control signal including the driving unit movement compensation signal to the driving unit.
An auto stabilization unit usable with a photographing apparatus, the auto stabilization unit, comprising:
- a detecting unit to detect vibration;
- and
- a controller to compensate for the vibration by at least one of generating a driving unit control signal according to at least one of one or more dynamic characteristics of the driving unit of the photographing apparatus and adding a driving unit movement compensation signal to control displacement of the driving unit to the driving unit control signal.
A photographing apparatus, comprising:
- a photographing element to photograph an image;
- a driving unit coupled to the photographing element, and to move the photographing element;
- and
- a controller to compensate for vibration by at least one of generating a driving unit control signal according to at least one of one or more dynamic characteristics of the driving unit and adding a driving unit movement compensation signal to control displacement of the driving unit to the driving unit control signal.
