Part #: HL-45A
Description: The HL-45A is a cutting-edge, high-performance digital camera with new-generation ASICs that support reductions in camera size, weight and power consumption. High performance is achieved through three IT CCDs that provide an astounding 900 (HL-45A) TV lines, or more, resolution, a modulation depth of 75% (5MHz), a dynamic range of 600%, a sensitivity of f10 (HL-45A) at 2000 lux and a S/N of 64dB (NTSC), 61dB (PAL).

For cost-savings, the HL-45A connects with existing TA/BS-OCP-40, and newly developed TA/BS/OCP-45 for wideband triax operation. The HL-45A sports a slew of capabilities for leading-edge performance. For example, a memory card can store operating status to facilitate camera setup. The camera uses an advanced RGB DTL System to enhance resolution, plus much more, all made possible through advanced digital signal processing.

High Density CCDs
High-performance 520,000-pixel(NTSC) for HL-45A and 620,000-pixel(PAL) for HL-45A IT CCD image sensors provide exceptional smear characteristics. A horizontal resolution of 900(HL-45A) 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 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 delivers a dynamic range of 600%. Even for high contrast subjects, video with proper contrast can be produced.
Sensitivity of f10(HL-45A)
A sensitivity of f10(HL-45A) 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) is 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, 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.
More Flexibility for High Image Quality
Memory Card
The HL-45A is memory-card-ready so that camera operating status can be stored. Thus, camera setup, color matching and identical DTL settings for several cameras is greatly simplified (The SmartMedia with a capacity of 2MB is used for storage.
Variable Shutter
In addition to six shutter presets, a variable shutter is also employed which can be set from 1/60.3 to 1/201 (NTSC), 1/50.3 to 1/200 (PAL) of a second.
+36dB Gain
A +36dB gain allows for minimum illumination of 0.7 (HL-45A) lx (f1.4). Because sensitivity is enhanced electronically, loss of resolution is minimized.
Filter
The HL-45A has a built-in CC filter disk. A color temperature conversion filter can be selected to best match surrounding illumination conditions.
High-Resolution Viewfinder
The HL-45A comes standard with a 1.5-inch high-resolution viewfinder that delivers a horizontal resolution of 600TV lines. This ensures clarity and consistently high image quality.
Menu Switch
Shutter speed and Super-V can be set with a menu switch located on the switch panel. Various camera settings can be made on screen in a menu-driven manner, thereby substantially improving ease of operation.
Low Center of Gravity
The camera head is designed with a low center of gravity for operator comfort. The camera head is compact, weighing less than 6 pounds. High-density CCDs are used, and the power consumption is a low 15W, thanks to newly developed ASICs.
Shoulder Pad
A new non-slip material is used for the shoulder pad. Pad position can readily be adjusted front and rear, as well as right and left angle.
