Sharp Corp. developed the “RJ24N3AAOPT,” a new 2-million CCD image sensor with a pixel size of 2.75 square micrometers.
It is for a 1/3.2- inch optical system (its light-reception part has the diagonal length of about 5.6mm). As a 2 million-pixel CCD image sensor, the smallest sensor commercially available is for a 1/2.7-inch optical system (diagonal length of 6.65mm). It is built in Canon Inc.’s small-size “IXY DIGITAL 300” digital camera and some other products.
According to Sharp, use of the new CCD imgae sensor enables makers to reduce the volume of the whole optical system of a digital still camera by approximately 35 percent compared with that of a 1/2.7-inch CCD image sensor. The reduction will open up possibilities of commercially viable smaller digital cameras in the future.
The total number of the pixels in the new sensor is 2.14 million (1,704 dots by 1,257 dots) and the effective pixels 2.01 million (1,630 dots by 1,230 dots). Its sensitivity is 130mV and its saturated output voltage 500mV. The 16-pin package is plastic DIP. Sharp plans to start shipping samples at the end of October 2001. The sample is priced at 3,000 yen. Also, it plans to start mass-production in March 2002 at a volume of 300,000 units per month.
