A support for an optical system of a digital camera is constructed which provides adjustable positioning of the lens elements in response to signals from the camera control processor. The support comprises multiple tubes, mounted for relative coaxial movement, which support a lens element. At least one of the tubes is adjustable in position relative to a main support tube. The adjustable tube is engageable by piezoelectric elements. Each piezoelectrical element is mounted to a flexible printed circuit board which contains the camera operating system and is mounted on the support tube.

The stereoscopic display without using eye-glasses according to claim 1, wherein each shutter region of each shutter means has the same size, and the shutter means are laterally spaced apart from each other by a distance equal to a length integer multiplied by a length of the shutter region. 4. The stereoscopic display without using eye-glasses according to claim 1, wherein said first and second shutter means are arranged at a stop of projection lenses of said projectors and includes two or more than two shutter regions, which switch light transmission and light shading and are placed laterally in width less than the diameter of the stop.
