Sony F23 Specifications page 5

4:4:4 RGB Image Capture
The F23 was designed from the outset to preserve
all the detail, contrast and color that the image
sensors can capture. Most digital HD acquisition
works within the ITU-R BT.709 standard, which
specifies 4:2:2 sampling and Y/Cb/Cr encoding.
The F23 exceeds this with full 4:4:4 RGB image
capture and output. As a result, you get natural
skin tones, rich color and exceptional resolution.
The robust 4:4:4 signal is ideal for the most
exacting green-screen compositing, aggressive
color correction, and other image manipulations in
post. The 4:4:4 signal excels in demanding feature
film, commercial and episodic TV productions. For
other projects, the F23 also supports high-quality
4:2:2 Y/Cb/Cr.
Over 12 Stops of
Exposure Latitude
Many HD cameras are
limited to 9 stops of exposure
latitude, forcing
cinematographers to
compromise between blown-out
highlights or crushed blacks.
Thanks to a revolutionary CCD
design and 14-bit analog-to-
digital conversion, the F23
achieves more than 12 stops of
exposure latitude. This enables you
to shoot challenging, high-contrast
scenes, and create images that
stand up better through vigorous
post manipulation.
1080/60P Image Sensors
Because the F23 uses three separate image
sensors for Red, Green, and Blue, there is no need
for Bayer color filter arrays. And color values are
never "interpolated" from neighboring pixels. You
get the full resolution of 1920 (H) x 1080 (V) images
at picture rates of up to 60 progressive frames per
second. Even in deep
shadows, image noise is
remarkably low. And
sensitivity is an ample T10
(in 23.98P mode).
Wider Color Gamut
Most HD cameras are limited
to the ITU 709 high definition color gamut. Thanks
to an improved prism block and digital signal
processing of up to 36 bits, the F23 can go beyond
ITU color, ideal for projects destined for theatrical
release. Of course, ITU 709 color is always available
for projects that require it.
Multiple Frame Rates
The F23 captures the Common Image Format
(CIF): 1920 (H) x 1080 (V). To support a full range
of cinema, episodic and commercial productions,
the camera offers a choice of frame rates from
1 to 60 frames per second in 4:4:4 RGB or 4:2:2
Y/Cb/Cr. All of these frame rates can be recorded
on the docking SRW-1 HDCAM SR field recorder.
(For the SRW-1,Sony plans to support frame rates
of 1 fps to 60 fps in 4:4:4 mode with the
introduction of an additional HKSR-103 RGB 60P
processor board.)
