Abstract
A characteristic point such as an image contrast of a target image in an image screen of an object produced by an image sensor is counted, a correlation between counts at two points in time is determined. A drive means for preventing vibration of an imaging lens is controlled in accordance with the correlation signal and imaging information such as in-focus or out-of-focus information.
Claims6
An image stabilizing device comprising:
- lens barrel having an imaging optical system and an image sensor integrated with said lens barrel;
- housing for supporting said lens barrel;
- generating means for generating a signal relating to vibration of the image based on image information produced by said image sensor;
- and
- driving means for moving said lens barrel relative to said housing based on the signal produced by said generating means to correct the vibration.
