TOKYO Matsushita Electric Industrial Co., Ltd., has announced an image sensor architecture that features advantages of both CCD and CMOS sensors.
Maicovicon consumes less power consumption than a charge couple device and exhibits higher quality image than a CMOS sensor.
Maicovicon will be available in 1.3 Megapixel and 2 Megapixel versions with a pixel size of 2.8 mm square. The 1.3 Megapixel sensor occupies an area of diagonal length of 4.5mm for a 1/4-inch optical system while the 2-Megapixel sensor has a 5.6mm diagonal length for a 1/3-inch optical system.
The photosensitive area in each pixel is about three times larger than that of CMOS sensors and almost equal to that of CCD sensors.
"Matsushita has been developing CMOS sensors and made many prototypes, but the sensitivity and capability of moving image capture were unsatisfactory. We decided to cover application areas that CMOS sensors cover with Maicovicon," said Susumu Koike, president of Semiconductor Company of Matsushita.
Maicovicon exhibits a power consumption of 25 mW for the 1.3 mega-pixel sensor and 45 mW for the 2 mega-pixel model, which are comparable to that of CMOS sensors, and are only about one-fifth the power required for a CCD image sensor with the same number of pixels.
Matsushita will begin volume production of 1.3 Megapixel sensors this month with a capacity of about 2 million units a month and 2 Megapixel sensor production will follow next month. The company intends to ramp up the total production volume to 8 million units by autumn.
