<p>An apparatus and method for electronically acquiring images using a frame-transfer CCD sensor (202) with a reduced-height storage area (206) reduces saturation artifacts in the resulting digital images by modifying the energy profile of the CCD sensor in an image area (204) of the CCD sensor after an exposure period. The energy profile of the image area of the CCD sensor is modified by decreasing (510) the potential applied to the substrate (302) of the image area such that dissipation of saturated charges remaining in the image area of the CCD sensor is significantly reduced when the majority of accumulated charges is transferred from the image area to the storage area of the CCD sensor. Thus, the saturated charges in the image area and the storage area are substantially maintained at their initial levels, which results in digital images with reduced saturation artifacts.</p> |
