Micron Technology has introduced a 1.3 megapixel (MI-1300) low-power CMOS progressive scan active pixel image sensor. The part has been designed to meet the demands of digital still cameras, digital video cameras, and PC cameras.
The sensor output of the MI-1300 is 30 frames/sec progressive scan, exceeding frame rates available for CCD sensors designed for digital still camera applications.
Through the use of Micron’s low-leakage DRAM process technology, the sensor has a dark current of 20 electrons per second. The sensor also maintains a low temporal noise of less than 10 electrons, allowing images to be captured in low light levels.
Micron claims that sensor’s performance on both of these parameters, as well as others, is similar to CCD levels and exceeds the performance of most competing CMOS sensors. Proprietary process techniques have also been applied to achieve a high degree of colour separation that results in richer colours.
The MI-1300 has on-chip timing and control, analog-to-digital conversion (ADC), programmable gain and exposure control, auto black level calibration, and snap-shot and viewfinder modes. It is capable of both continuous video and single frame capture with sync input and strobe output as well as windowing, horizontal and vertical blanking control.
The MI-1300 is the first in a family of megapixel products and will be followed by higher resolution megapixel devices later this year.
