JVC Professional Products Company unveiled the GY-HMQ10, the world’s first handheld 4K camcorder, which captures, records and plays video images at four times the resolution of high definition television (HDTV).
Powered by JVC’s Falconbrid large-scale integration (LSI) chip for high-speed signal processing and a 1/2-inch CMOS imager with 8.3 million active pixels, it delivers real-time 3840×2160 footage at 24p, 50p, or 60p.
“We’re witnessing the birth of what is destined to become a broad market for full 4K end-to-end production,” said Edgar Shane, JVC’s general manager of engineering. “The GY-HMQ10 is a breakthrough product that opens up 4K imaging to users who previously wouldn’t have considered it,” he added.
High-resolution 4K still picture imaging has been around for several years in DSLR cameras, and motion video capture with these cameras has always been done at a lower video resolution because of lack of processing power, JVC says. Likewise, high-end digital motion picture cameras may capture 4K images, but often provide a raw data output to an external storage array for later processing—again due to lack of processing power in the camera, the company says.
JVC’s exclusive Falconbrid LSI processing takes raw image data from the camera’s CMOS device and dematrixes it in real time, but unlike many high-end 4K cameras, the GY-HMQ10 is able to output 4K images to a monitor or projection system in real time with virtually no latency, JVC says. That capability opens up applications in cinematography, medical microscopy, telepresence, specialized observation/surveillance and live wide-view event coverage, the firm says.
Using MPEG-4 technology and a variable bit rate H.264 codec operating at up to 144 Mbps, the GY-HMQ10 records up to two hours of 4K video to economical SDHC or SDXC memory cards. In addition to 4K imaging, the GY-HMQ10 also captures and records 1080i or 1080/60p full HD, with detail provided by its 8.3 megapixel imager and superior lens. HD is recorded on a single memory card in a format compatible with most editing systems. That combination of 4K and HD imaging was requested by attendees of JVC’s 4K forums, conducted throughout North America last year and is unique in the camera industry.
