Abstract
A digital photographing apparatus and method are disclosed, The digital photographing apparatus includes a position sensor configured to detect position information of a lens unit, and an optical driving processor configured to calculate a movement position variation of the lens unit based on the position information of the lens unit, compare the movement position variation with a reference movement position variation, and cause the movement position variation to converge on the reference movement position variation.
Claims20
A digital photographing apparatus comprising:
- a position sensor configured to detect current position information of a lens unit for a driving amount;
- and
- an optical driving processor configured to:
- calculate a movement position variation of the lens unit based on the position information of the lens unit,
- compare the movement position variation with a reference movement position variation among reference movement position variations, and
- cause the movement position variation to converge on the reference movement position variation by adjusting the driving amount,
- wherein the reference movement position variations are constants stored in the optical driving processor or in a separate memory, and
- wherein the optical driving processor is configured to apply different bit resolutions to sections of the movement position variation based on differences to the reference movement position variation.
A method for controlling a digital photographing apparatus, the method comprising:
- detecting a current position information of a lens unit by a position sensor for a driving amount;
- calculating, at an optical driving processor, a movement position variation of the lens unit based on the position information of the lens unit;
- comparing the movement position variation with a reference movement position variation among reference movement position variations;
- and
- causing the movement position variation to converge on the reference movement position variation by adjusting the driving amount,
- wherein the reference movement position variations are constants stored in the optical driving processor or in a separate memory, and
- wherein the optical driving processor is configured to apply different bit resolutions to sections of the movement position variation based on difference to the reference movement position variation.
