JVC develops next-gen high-def engine

Victor Company of Japan, Ltd, (JVC), has developed a next-generation high-definition image processing system, for use in large-screen displays.

The ‘engine’ uses a new image processing algorithm and features greatly increased bit accuracy to give high motion image quality which meets the needs of new-format high-quality image signals, the development of display panels beyond 10 bits, and the trend for larger screens.

The engine can handle 36-bit Deep Colour input at 12bit x3 for R, G and B. It uses corresponding 12bit x3 36-bit RGB processing to maintain high-accuracy signal processing quality, achieving a 68-billion colour expression capability and high-grade image reproduction without perceptible image deterioration from digitisation.

JVC uses bit extension technology called Real Bit Driver in its new engine. This turns 8-bit images into images with 12-bit precision.

This overcomes a disparity between LCD panel technology and digital image content such as DVDs - LCD panels are evolving to RGB 10-bit display, while 8-bit RGB / Y,Cb,Cr(Y,Pb,Pr) is becoming the norm for content such as digital broadcasts and DVDs.

JVC’s Real Bit Driver can reproduce smooth gradations without losing the perceived resolution of the image source and without false contours in gradation caused by too few bits.

The new engine also uses 120-frame Clear Motion Drive Technology which gives a high level of noise suppression without blurring motion on fast moving images.

It also incorporates JVC’s latest GENESSA high-definition technology. JVC has introduced Real Colour Creation for greater reality in colour reproduction, Intelligent Gamma, which fine-tunes contrast, and Intelligent Clear, which provides crisp low-noise images.

JVC has also utilised its own x.v.Color enabled signal processing technology, which gives more realistic colour expression, and creates perception of depth of field and texture.

JVC’s next-generation high-def engine integrates these new image processing technologies on a single system LSI. The company plans to utilise the engine in LCD panels and other large-screen displays.
