The
new HDW-F900 camcorder offers high
definition image-capture equivalent to the picture quality associated
with 24-frame 35mm film.
24P HDCAM imaging elevates this image quality to the ranking of a
35mm film release print derived from a 35mm original capture.
The state-of-the-art, Sony HDCAM compression scheme is a frame-based
digital compression strategy, where every frame of the signal is treated
as a single entity. HDCAM maintains exceptionally high picture quality
and multi-generation robustness for both progressive and interlace
signals. |
Advanced
digital pre-filtering and dynamic bit-allocation for luminance and
chrominance components (based on the statistical analysis of the picture
content) are combined with a mild compression ratio of only 4.4 to
1 to give a total on-tape recorded data ratio of a modest 185 Mb/s
at 60i. This, in turn, ensures high-integrity camcorder recording
in the most hostile of environmental conditions.
The frame rate switchability of the camcorder allows 24, 25 or 30
progressive frames per second capture as well as a choice of either
50 or 60Hz interlace - all at the push of a button.
The Art of Image-making
The progressive scan CCD sensor at the heart of the HDW-F900 marks
a significant advance in Sony HAD CCD technology. It is a development
that now makes possible image capture over a range of frame rates,
and ensures that their quality is at the highest possible level. This
progressive scan CCD sensor provides a sensitivity of f10 at 2,000
lux (at 60i) providing subjectively noise and grain-free pictures.
At 24fps, with a 1/48-second shutter speed (equivalent to a 180? film
camera shutter setting), the exposure index of the HDW-F900 is approximately
equivalent to 300 ISO*. It allows the acquisition of gain-free imagery
in deeply shadowed areas of a scene.
Superb CCD highlight-handling greatly extends the Exposure Latitude
of the camera , allowing directors the dramatic freedom to shoot and
capture extreme highlights in otherwise low-key scenes. |
