Digital imaging device

A digital imaging device, comprising:

• a casing extending along an extension axis, wherein the casing comprises a closed end and an open end opposite to the closed end;
• a photosensitive device disposed inside the casing and adjacent to the closed end, wherein the photosensitive device has a photosensitive element facing the open end;
• a light shielding barrel disposed inside the casing and extending along the extension axis, wherein the light shielding barrel comprises a fixed end and a movable end, the fixed end is fixed inside the casing and surrounding the photosensitive element;
• a movable lens barrel coaxially disposed with the light shielding barrel, wherein the movable lens barrel comprises a lens end and a driving portion, the lens end comprises an optical lens, the optical lens is coaxially disposed with the photosensitive element;
• and
• a driving device connected to the driving portion of the movable lens barrel, wherein the driving device drives the movable lens barrel to move axially relative to the light shielding barrel, so that the optical lens selectively moves near to or away from the photosensitive element.
