Abstract :
For multimedia applications, 30Frame/s 2/3 inch 1.3M pixel progressive scan interline-transfer CCD (IT-CCD) image sensor employs an optimized well for the horizontal CCD (H-CCD) and a wide bandwidth amplifier for 49 MHz operation. An 8-phase drive for vertical CCDs (V-CCDs) makes it possible to carry out a variety of operations such as 1050 line progressive mode and 1049 line wide dynamic range interlaced mode. For still camera use, removing residual charges stored in the V-CCDs before exposure is essential. A narrow-channel barrier overflow drain attached under the H-CCD automatically drains extra charge and requires neither overflow control gate nor additional masks.
