ABSTRACT:
A technique and structure is used for producing high resolution color images using a monochrome area charge-coupled device (CCD) 64 and a sequential color illumination scheme. The monochrome CCD 64 comprises a plurality of semiconductor storage cells 76, the semiconductor storage cells 76 being configured in an array having vertical columns 74 and horizontal rows 79. The entire CCD 64 is exposed to a first color image. The charge packets 82 stored in two adjacent horizontal rows as a result of the exposure are then shifted into a third horizontal row. The CCD 64 is then exposed to a second color image. The charge packets 82 stored in the first horizontal row as a result of the second exposure are then shifted into the second horizontal row. The CCD 64 is then exposed to a third and final color image. The CCD output is digitized and stored in a frame. The color information of a particular location on the CCD array 64 is derived by utilizing a simple set of equations.
