This specification discloses a CCD imager which includes a line addressing circuit (24) which selectively addresses CCD imaging gates (48). Output signals are clocked under the gates (48) to a buffer register (30) which is constructed in the form of a tree. Signals from under each of the CCD gates (48) travel an identical length path through the buffer register (30) to a charge detection circuit (46) measured by the number of pixels involved. The output signals thus take the same time, or same number of clock pulses, to travel the length of the buffer register (30) to enable all line switching to be accomplished during the horizontal blanking time of a television thus eliminating the switching noise from the television screen. |
