Abstract
An autofocus camera is provided which restrains and corrects any tilt that may occur in the optical axis direction without the need of providing any additional new sensors for that purpose. The autofocus camera includes an image sensor for receiving light from an object and converting the light into corresponding electrical signals, a lens driving device having a lens for focusing the light from the object upon said image sensor, and a control portion for causing said lens driving device to adjust any tilt that may occur in the optical axis in response to the electrical signals received from said image sensor. The control portion is operated to cause the lens driving device to adjust any tilts of the optical axis with respect to the image sensor in the orthogonal directions with each other, so that the resolution signals at the predetermined positions of said image sensor can be maximized.
