4K Resolution
Historically, the movie theater experience has always exceeded that achieved by home entertainment systems. The advent of HDTV (1920 horizontal pixels) and technical improvements in home theater equipment have stimulated the movie industry to think further ahead into the future.
Meanwhile, the Hollywood movie studios have jointly agreed on standardizing 4K (4096 horizontal pixels) and 2K (2048 horizontal pixels) as the next-generation digital movie distribution and projection standards. Creating movies in 4K protects the future value of the content, and also provides a significant benefit to the theater audience.
In recent years, stadium-type seating is becoming increasingly popular among modern cinema complexes.
By sitting closer to the screen, the audience can enjoy a more immersive visual experience. However, those sitting in the front rows may witness pixel artifacts when the resolution provided by the projection system is not sufficient to fill the screen size. The SRX-R320 provides true 4K output, which reproduces the full detail of 4K content thanks to the 4K SXRD panels, 4K internal signal processing, and 4K-compatible optical system. Besides, providing four times the resolution of 2K projectors, the visual quality of 2K and HD content is also improved over those provided by native 2K and HD-resolution projectors.
High 2000:1 Contrast Ratio
The SRX-R320 offers a high contrast ratio of more than 2000:1 through the use of Sony’s unique SXRD device. The SXRD device itself achieves a contrast ratio of over 4000:1. This stunning picture quality makes the projector ideal for applications in which dynamic range is essential.
The high contrast ratio has been achieved through two key technologies – the ‘normally black mode’ system and an extremely thin liquid crystal cell gap.
Xenon Lamp Provides Highly Bright and Pure Light Source
A Xenon lamp, standard in film projectors, provides pure, superb color tonal reproduction essential to meeting the stringent requirements of digital cinema. Xenon lamps, which are designed for the SRX-R320 and available from lamp manufacturers, satisfy the wide color range required for digital cinema by dispersion at a very flat and wide light spectrum.
Variety of High-quality Lenses
Six optional zoom lenses are available for the SRX-R320. All lenses utilize very large image circles that contribute to minimizing the optical vignetting that typically occurs on projector lenses, and to obtaining the highest possible values of MTF (Modulation Transfer Function). With these features, the optical systems of the SRX-R320 have the capacity to reproduce resolutions higher than 4K, which is necessary to project 4K content exactly at 4K resolution. In addition, these lenses are designed to minimize chromatic aberrations using Sony’s accumulated technical knowledge
3D Dual Lens Adaptor
Attaching the 3D dual lens adaptor* to its lens mount, the SXR-R320 can deliver crisp 3D images** to screens up to 15 meters (50 feet)*** in width at 4.5 ft-L brightness. It allows full 2K resolution for the left and right eye simultaneously, resulting in a high-brightness, high-quality stereoscopic cinema presentation that offers more faithful reproduction of motion in 3D.
Anamorphic Lens
When projecting digital cinema content created in the CinemaScope format (4096 x 1716 pixels), the SRX-R320 cannot use all of the 4096 x 2160 pixels available for the 4K SXRD device. To improve this inefficiency, the optional LKRL-A001 Anamorphic Lens with Lens Changer Unit * was developed. When CinemaScope images (4096 x 1716 pixels) are input, the SRX-R320 extends them in a longitudinal direction via the projector’s image-processing function, which effectively uses all the pixels of the SXRD device. The the images in a transverse direction, so that the aspect ratio of the images projected on a screen can be restored to its original 2.39:1. This can increase the brightness level of the images on the screen by approximately 20%, allowing for the projector to provide a high brightness of 14 ft-L on screens up to 22 meters (70 feet) wide.
Lens Shift Function
The SRX-R320 is equipped with a lens shift function that allows projected images to be moved up and down or from side to side. This lens shift function can be operated manually via the finger screws incorporated on the projector’s unit. Using this function, the position of the projected images can be moved vertically by -50% to +50% and horizontally by -5% to +5%.
