Abstract
A CCD sensor has a shutter to prevent frame shift smear during transfer of an image from the image region to a store region. The CCD sensor has an extended dynamic range, because each integration is in two parts, the second part of which has a different sensitivity than the first part. In order to avoid an asymmetry in the uncovering and covering of the image region, a two-bladed shutter is used.
