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
I
n 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.
■
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.
