Abstract
An imaging apparatus is compensated for its movement during image acquisition of an object by acquiring the image through a lens subassembly in the apparatus which includes a liquid lens, sensing movement of the apparatus during image acquisition, and controlling the liquid lens to compensate for the effects on the image of movement of the apparatus. Preferably, the liquid lens is controlled so as to change its focal length.

A method for compensating an imaging apparatus for its movement during image acquisition of an object, comprising:
- acquiring the image through a lens subassembly in the apparatus which includes a liquid lens;
- sensing movement of the apparatus during image acquisition, wherein said sensing step comprises determining translational movement of the image on an image sensor by sensing rotational movement of the apparatus and the distance of the object from the apparatus;
- and
- controlling the liquid lens to compensate for the effects on the image of movement of the apparatus.
In an imaging apparatus, for compensating the apparatus for its movement during image acquisition of an object, the combination of:
- a lens subassembly in the apparatus which includes a liquid lens, for acquiring the image;
- a movement sensor sensing movement of the apparatus during image acquisition, wherein said movement sensor senses translational movement of the image on an image sensor by sensing rotational movement of the apparatus and the distance of the object from the apparatus;
- and
- a controller controlling the liquid lens to compensate for the effects on the image of movement of the apparatus.
An imaging apparatus including a symbol decoder, a liquid lens, at least one detector for detecting movement in at least two dimensions, and a controller, said liquid lens being controllable to reconfigure it by control of voltage on plural electrodes, said controller receiving input from said at least one detector, and for controlling voltage on the electrodes to reconfigure the liquid lens in plural dimensions to compensate for undesired movement of the imaging apparatus, wherein said at least one detector senses translational movement of an image on an image sensor by sensing rotational movement of the imaging apparatus and the distance of a symbol from the imaging apparatus.
