|PANASONIC ANNOUNCES SIGNIFICANT IMPROVEMENT IN MOS IMAGING PERFORMANCE|
New Free Firmware Upgrade Addresses ‘Flash Band’ Effect of Rolling Shutter Imagers
|LAS VEGAS, NV (April 19, 2009) Here at NAB, Panasonic announced a new free firmware upgrade for the recently-released AG-HPX300 10-bit, 4:2:2 P2 HD camcorder that will enhance its performance compared to the growing number of products now utilizing MOS imagers.
Panasonic’s HPX300 is the world’s first affordable 10-bit, 4:2:2 professional HD camcorder, providing master quality, full 1920 x 1080 resolution AVC-Intra recording and professional features like variable frame rates. It incorporates advanced 1/3” 2.2-megapixel 3-MOS image sensors to acquire full native resolution 1920x1080 HD images. These advanced 3-MOS imagers provide exceptional image quality while minimizing flare.
The Flash Band Compensation firmware upgrade compensates for the “flash band” effect experienced by most MOS-based imagers.* As these imagers utilize rolling shutter, which records images line by line instead of simultaneously, as with global shutter technology, they tend to be susceptible to image variance when a light flashes during shooting. A light band (flash band) can appear in the continuous two frames when a flash occurs, similar to that from a still camera or strobe light.
The free firmware upgrade enables the camera to use a newly developed LSI signal process that removes the flash artifact. It detects the “flash band” frame and combines it with the previous unaffected frame image to compensate for divided flash band frames and maintain the natural frame sequence.
The Flash Band Compensation firmware upgrade for the HPX300 will be available on the download section of the Panasonic Broadcast website, www.panasonic.com/broadcast, this summer.
