IC Media announces 3-Mpixel CMOS image sensor
JANUARY 27--IC Media Corporation (San Jose, CA;www.ic-media.com) is offering a new 3-Mpixel CMOS image sensor, specially designed to provide high-quality images required for mainstream digital cameras. Utilizing the company's new high-performance sensor pixel design, the products simultaneously enable 3-Mpixel cameras to be more affordable, while offering even clearer pictures.
"The image quality provided in this high-resolution sensor is at a level competitive with charge-coupled-device sensor products. Reaching this image-quality milestone now provides camera designers with a cost-effective/simple-to-design solution to meet their product requirements," stated Ben Wu, president and chief executive officer.
Using 0.25-μm process technology, IC Media was able to reduce the size and power requirements for digital camera designers. The power requirement remains below 6 0mA at six frames/s and below 100 mA at 12 frames/s. The ICM-110T uses a dual-voltage power scheme for maximum dynamic range with 2.5 V for the circuit and 3.3 V for the sensor array.
The ICM-110T single-chip, digital color imaging device incorporates a 2048 x 1536 (3,145,728 pixels) sensor array capable of operating at up to 12 frames/s with subsampled quarter and quarter-quarter (1/16) resolutions, operating at higher frame rates in a progressive manner. It also provides register-selectable frame rates of 12/6/4.3/2.1/1.8/1.2/0.9/0.42 frames/s modes. Correlated double sampling is performed by the internal 11-bit analog-to-digital converter and timing circuitry. The output is 10-bit raw data that can be fed to other digital signal processor, color processing, or compression chips.
