Sharp Develops 12 Megapixel CCD for Digital Camera


Sharp Corp. has developed a 1/1.7-inch CCD sensor with an effective pixel count of 12.19 megapixels for use in compact digital cameras. The new sensor comes in two models, the basic RJ21Y3BA0ET and upper RJ21Y3DA0ET with high-sensitive imaging function. With its proprietary micro fabrication technology, Sharp has achieved what it claims to be “the industry’s smallest-class” pixel size of 1.88 μm square so that the product features compactness and high sensitivity. It allows high-resolution output to A3 size. It has downward compatibility with its existing models (with an effective pixel count of 10 megapixels) in the optical system and pin configuration.


Thus, the existing optical system can be used as-is when developing new digital cameras. In RJ21Y3DA0ET, CCD the pixel data in units of four adjacent pixels are respectively added by color R, G and B so that the sensitivity in shooting may be quadrupled. This is especially effective for short time exposure. The volume production is slated for January 2007.
