A digital camera includes a CCD imager having an interline transfer scheme. A first charge produced due to first exposure is read from light receiving elements positioned vertically intermittently. A second charge produced due to second exposure is also read from the same light receiving elements to vertical transfer regions. Here, the first charge is vertically moved simultaneously with or prior to reading out the second charge. The moving distance, at this time, is equal to or greater than a distance that the light receiving elements continue in the vertical direction. As a result of this, the second charge will not be mixed with the first charge. The first and second charges are subjected to a compositing process to display a composite image on an LCD.

The present invention is concerned with a process for the formation of dental restorations from glass-ceramic materials, and the resulting dental restorations. In this invention, a dental restoration is prepared by placing a glass-ceramic material in a heat-pressure deformable crucible. Heat is then applied to the crucible in order to bring the glass-ceramic material to working range at temperatures above its liquidus temperature. The crucible in which the glass-ceramic material is placed has heat-pressure deformation properties which are matched to the working temperature of the glass-ceramic material being heated. The heat deformation properties of the crucible must be such that when the glass-ceramic material in the crucible is in the working range, the crucible is heat-pressure deformable without rupturing. Once the glass-ceramic material is heated to its working temperature, the crucible is brought into contact with a mold having a preformed cavity therein, the cavity being in the shape of the desired dental restoration. As the distance between the heated glass-ceramic material and the mold is decreased, the crucible is deformed to form a seal with the mold, thereby facilitating the injection of the molten glass-ceramic material into the mold cavity. An interactive seal between the crucible and the mold may be provided for. The composite process may be carried out in a vacuum. The resulting dental restoration has superior optical esthetic and strength properties. The invention further includes the heat-pressure deformable crucible. The invention includes dental restorations which are formed from particular lithium-disilicate glass-ceramics. In addition to forming dental restorations by the process of this invention, the dental restorations may be milled.
