AltaSens, Inc., announced availability of its 1/3-inch ProCamHD 2460 and 2462 sensors for deployment in the latest high definition video HDV camcorders and HD cameras. Both 1.3 megapixel sensors generate crystal-clear progressive 12-bit digital video at 1280 by 720 resolution and 75 MHz rate. The result is smooth 720/60p HDV or 50 Hz SXGA.
ProCamHD technology uses CMOS imaging system-on-chip (iSoC) integration to enable noise-free megapixel video and rapid-fire snapshots, even under non-optimum lighting conditions. Other CCD and CMOS sensor manufacturers instead reduce HD video sensor resolution to cut noise and attempt to recover lost resolution via increasingly complex back-end processing.
The 2462 sensor supports single-chip cameras with the latest RGB color filter and microlens technology
. Its maximum power dissipation of 350 mW lengthens battery life. The 2460 is the monochrome counterpart sensor with advanced microlens array for low-power 3-CMOS cameras. Both deliver low noise via tapered reset, a patented technique for greatly reducing noise and maximizing dynamic range. While film-like with respect to exposure latitude, each sensor's 60 Hz frame rate largely prevents cinema-like smearing.
AltaSens is supporting 246X sensor evaluation and initial setup via an evaluation kit and AltaSens' ProCEED Software Package. The evaluation kit comes with Megapixel-quality lens, cabling, and frame capture board for use in a PC. The ProCEED software simplifies sensor programming while enabling real-time PC-based imaging and extensive sensor characterization.
