Sony SRX-R220 - Manual (Page 6)

Operational Features
Keystone Masking
To compensate for keystone distortion, which typically
occurs when the projector is not installed directly in front of
the screen, the SRX-R220 and SRX-R210 have an image-
masking function. To determine a position of the masking,
this allows users to set a further two points as well as four
corner point, which is effective when projecting onto a
curved screen.
Zoom/Focus Memory Function
The SRX-R220 and SRX-R210 are equipped with zoom and
focus memory functions that make it easy to switch the
projection between two types of aspect ratios.
When used with the optional zoom lens LKRL-Z114C,
LKRL-Z116C, LKRL-Z117, LKRL-Z119, or LKRL-Z122 , the
zoom and focus positions for 1.85:1 VistaVision™ and
2.39:1 CinemaScope™ can be stored and instantly recalled
via the SRX Controller software. This allows for full-screen
display regardless of the aspect ratio. An electronic vertical
alignment feature is included in the same memory to
compensate for vertical changes in the image should the
projector be mounted at a downwards angle.
Color Space Conversion (CSC)
function
The SRX-R220 and SRX-R210 feature a Color Space
Conversion (CSC) function, which helps users easily adjust
the projector’s color space to that which is defined in the
DCDM (Minimum D-Cinema Color Gamut) or ITU-R BT.709.
The target color gamut parameters required to meet the
DCDM or ITU-R BT. 709 standards can be automatically
calculated from settings on the supplied SRX Controller
software, and then applied to the projector. The internal test
generator simplifies adjustment and lets the operator align the
projector in minutes.
12-bit LCD Driver
The SRX-R220 and the SRX-R210 utilize a 12-bit imager
driver for reproducing extremely natural images.
Gamma Curve Selection
The SRX-R220 and the SRX-R210 provide three preset
gamma curve values. Users can select an optimum value
from 1.8, 2.2, and 2.6 according to the desired color tone.
Squeeze Mode Function
The SRX-R220 and SRX-R210 allows squeezed images (16:9
or 1.896:1) to be changed to 2.39:1 un-squeezed images.
This can be done electrically without an anamorphic lens,
and be activated by the SRX Controller software.
