JVC LSI Enables High-speed Image Processing in HD Camcorders


JVC has developed new LSI for high-speed processing of Full High-Definition video and ultra-high-resolution 4K2K stills on one chip for HD camcorders.

The LSI enables shooting and recording Full HD, including both 2D and 3D images, and also ultra-high-resolution 4K2K images of approximately four times the resolution of Full HD.

In addition to 2.7 times faster processing than previous CPU, the new CPU supports various signal-processing technologies that have been fully revised for high-resolution image recording.

Specifically, the camera-signal processing is 1.7 times faster than JVC's previous technology, enabling 8.3-megapixel video at 60 frames per second. The H.264 video processing power is double JVC's previous technology, enabling compression of 2.07-megapixel images at 60 frames per second. JPEG still-image processing is also 5.5 times faster than JVC's previous technology, enabling compression at up to 8.3-megapixel images at 60 frames per second.

The LSI also achieves real-time 3D compression of separate Full HD images (1920 x 1080/60p) from right and left cameras using MPEG-4 MVC. The amount of data is double the conventional side-by-side 3D recording format, enabling high-resolution Full HD 3D images with one chip.

The camera's processing circuitry and a high-speed JPEG engine enable the simultaneous capture of Full HD video and 8.3 megapixel stills at 60 frames per second.

The LSI also offers gigh-speed video capture for 3D recording at 300 frames per second based on high-speed video codec.

JVC's new LSI incorporates 40nm process technology for high functionality, 40% reduction of power consumption and 50% reduction of system costs compared to previous LSIs.

JVC will exhibit a new consumer camcorder with the LSI at the 2011 International Consumer Electronics Show (CES), which will take place in Las Vegas, Nevada from January 6 to 9.
