“…In this way, the Nyquist limit was increased by a factor of 2 over that of the static array; however, image flicker appearing at highly resolved images near the double-enhanced Nyquist limit was a problem. This problem was solved by wobbling the array to enlarge the horizontal pixel apertures so that they slightly overlapped [15].…”

The state of the art in visible spectrum solid -state area arrays is discussed from an historical perspective. The major development during the decade of the 1960's was the first demonstration of self-scanned solid -state area imagers using transistors as photosensors. During the decade of the 1970's, major advances included the charge-coupled concept, temporal and spatial noise reduction and the understanding of aliasing vs. MTF. During the 1980's, solid -state imaging has continued to mature with advances in the control of defects, development of color filters for one -chip color camera, development of vertical anti -blooming and anti -smear structures and the use of thin films for vertical photosites.

“…There are two methods to improve the spatial resolution of a CCD imager : (1) a pixel number increase ; (2) pixel position changing relative to the scene. Pixel position changing is to make a device in a CCD imager which can change pixel position relative to incident light intensity distribution.…”

This paper presents the principle to enhance the spatial 2-D resolution of spatial 2-D resolution and the possibly available limitation of maximum resolution. The paper also reports on image signal processing for 2-D high definition picture and the hanging -up piezoelectric bimorph construction designed to improve both horizontal and vertical resolution respectively by one time. The regenerated signal can be compatible with current TV mode.
