We have developed a 1.3 million-pixel (1280x1024) progressive-scan CCD image sensor for digital still cameras and PCs. It has a 2/3-inch optical format with 6.7um square pixels and 5 : 4 aspect ratio. This image sensor is able to perform progressive readout without using a mechanical shutter. Better reproduction of color is achieved by a primary color filter, and we have achieved high resistance to fading by employing pigment as the on-chip coloring material. We have also developed a timing generator suited for this CCD image sensor. Through the use of this timing generator, an external trigger is also introduced.
