Abstract:
1. An imaging device comprising: a lens; an image unit which images an object through said lens; an adjust unit comprising a piezoelectric element, the adjust unit configured for performing a first adjustment by deforming said piezoelectric element by applying a voltage thereto and thereby causing a distance between said lens and said image unit to be adjusted; a first detector which detects an electric signal generated by deformation of said piezoelectric element in response to a force external to the imaging device; and a controller which controls said adjust unit and causes the adjust unit to perform a second adjustment that causes said distance between said lens and said image unit to be readjusted when said electric signal resulting from deformation of the piezoelectric element caused by an external force is detected by said first detector; wherein said controller controls said piezoelectric element so that detection by said first detector is switched off while said adjust unit is performing adjustment and that detection by said first detector is switched on while said adjust unit is not performing adjustment.
