High Density CCDs
High-performance 520,000-pixel (NTSC), 620,000 (HL-45A), 600,000 (HL-45AW)-
pixel (PAL) IT CCD image sensors provide exceptional smear characteristics. A
horizontal resolution of 900 (HL-45A), 750 (HL-45AW) TV lines, or more, and a
modulation depth of 75% (5MHz) deliver top-notch performance.
Digital Process
Newly-developed digital processing ICs (ASICs) with 12-bit analog-to digital(A/D)
conversion deliver a high S/N ratio of 64dB (NTSC), 61dB (PAL). Because all the
processing after PRE KNEE is digitized, high image quality with rock-solid stability is
achieved. Because the processes, such as gamma and DTL, are also digitized, video
with a good S/N ratio is maintained during operating conditions.
Super-V
The Super-V function enhances the vertical resolution by 20% through combination
of the frame store mode and the 1/60 (NTSC), 1/50 (PAL) shutter.
Color Matrix
A six-axis color linear matrix circuit is incorporated to compensate for optics-related
color reproduction, thereby achieving vivid, true-to-life color tones.
Dynamic Range
The HL-45A/45AW delivers a dynamic range of 600%. Even for high contrast
subjects, video with proper contrast can be produced.
Sensitivity of f10(HL-45A), f11(HL-45AW)
A sensitivity of f10 (HL-45A), f11 (HL-45AW) at 2000 lx is realized. A greater depth
of field facilitates simple focusing. In addition, clear images can be acquired even
when the camera is used under poor lighting conditions.
Lineup for Supporting User Needs
In flexible response to diverse user needs, the HL-45A (a fixed aspect ratio of 4:3)
and the HL-45AW (switchable between 4:3 and 16:9) are available.
Digital-Specific Versatile Videography
RGB DTL Method
Conventionally, the vertical DTL signal is derived from the G signal alone, so that the
sense of resolution for red and blue subjects was insufficient.This shortcoming is
overcome by the HL-45A/45AW, which produces independent vertical DTL signals
from the respective R, G, and B signals, thereby substantially enhancing the sense of
resolution for red and blue subjects.
Black Stretch
The Black Stretch function improves the reproduction in shadow areas of a subject
by raising the video level only for low-brightness portions. The stretch level is variable
in 3%, 5%, and 7%.
DTL Function
Numerous DTL functions are incorporated, such as, Diagonal DTL, Soft DTL, Skin
DTL, as well as variable boost frequency(in 8 steps) and H/V balance.
