Digital Cinematography provides the cinema industry with new ways to produce and display movies while preserving the artistic intent of the cinematographer. It provides new techniques for composition and display of cinema that improve the quality and allow for widespread distribution without the use of celluloid.
JVC has developed a new technology - D-ILA, that provides the basis for cinema projectors that provide film-like images in post-production and in the theatre.
The D-ILA (Digital Direct-Drive Image Light Amplifier) technology of JVC is based on innovations in CMOS microchip design and liquid crystal technology. For true HDTV performance the D-ILA has QXGA performance with 2048 x 1536 pixels on a single 1.3 inch display modulator. This total resolution of 3.2 million pixels makes it completely unique in the high quality projection market where other projectors provide only 1.3 million pixels. This makes possible the display of HDTV images at the complete native resolution of 1920 x 1080 pixels.
This high resolution performance has been realized in the benchmark JVC QX-1 projector. With the QXGA resolution combined with a contrast ratio of greater than 1000:1, the QX-1 is the new standard of excellence for Digital Cinema presentation. The high light output of 7000 lumens make it possible to project images onto screens in many venues.
JVC also has a complete line of D-ILA projectors with a range of resolution formats and light output for a wide range of applications. In particular compact projectors provide the unique qualities of D-ILA technology on smaller screens for Home Theatre and post production applications.
The D-ILA innovative LCOS (Liquid Crystal on Silicon) design is the key to reproducing all the details in a high-definition image. The D-ILA has a pixel array with a 93% fill factor and thus virtual elimination of the annoying "grid" so evident in other fixed matrix technologies. Compared with micromirror technology the liquid crystal image modulator smoothes the image and eliminates artificial sharpness associated with the micromirror edges. Thus D-ILA images are as smooth and natural as film with accurate reproduction of the details and information contained in the original digital source. Also compared with digital displays that use "pulse code modulation" and linear response to create gray levels, the D-ILA uses "analog gradation" with an S-shaped response. This makes it possible to reproduce dark areas so important in cinema images with high S/N (signal to noise ratio) and absence of contouring.
