1. OUTLINE 2. FEATURES 1 - 1
1. OUTLINE
The HDL-45E/E1 is a “3CCD multiple-purpose HDTV camera,” in which our cutting-edge camera technologies and digital
technologies are used to implement high definition, high stability, and high reliability.
It uses 2,300,000-pixel 3CCD supporting full HDTV (1920 × 1080) and digital process LSI (ASIC) used for a broadcasting
studio HDTV camera to get resolution and color reproducibility comparable to a broadcasting studio HDTV camera.
Picture with broad tonal range, from dark part to highlighted part, can be obtained thanks to a 14-bit (16,384 tones) A/D
converter.
Since the camera has a one piece structure which can output HD SDI independently, it can be used for various applications
from broadcasting ones such as weather camera and news appearance to industrial ones such as medical services and PC
input.
2. FEATURES
■ 2,300,000-pixel (1080i Readout) 3CCD Camera
The HDL-45E/E1 uses 2/3-inch 2,300,000-pixel AIT (Advanced Interline Transfer) supporting full HDTV
(1920 × 1080) to implement a high definition of horizontal resolution 1000TV lines and S/N ratio = 56 dB
(Sensitivity : F11) in HDTV system.
■
Support of 2/3-inch Serial Digital Interface Lens
Commercially-supplied HDTV lenses and SDTV lenses can be used since the lens mount includes BTA S-1005B
as standard equipment. ZOOM/FOCUS control can be performed with RCP-50B panel in combination with lenses
supporting serial digital interface.
■
Built-in Filter Servo
The camera incorporates filter servo. Filter position can be remotely controlled from various control panels.
■
ND Filter and Electric Color Temperature (ECC) Filter
The HDL-45E/E1 incorporates four-position optical ND filter. IRIS value can be controlled delicately in accordance
with the subject even at a place where illumination is extremely different such as outdoor.
Electric color temperature (ECC) filters (3200K/5600K) are used as CC filter. Suitable white balance can be
obtained without decreasing camera sensitivity even under the illumination of high color temperature such as
fluorescent lamp. The HDL-45E/E1 also provides the AWB mode, which automatically switches over ECC; 3200K/
5600K, when the operator pushes a switch, to cover the full range of color temperature without regard to the
relationship between the subject and the color temperature filters. In addition, since ND and ECC filters can be
operated separately, ND filter can be used even under studio illumination (3200K).
■
Low Noise Gain Increase
Low noise feedback-type amplifier circuit is used as master gain increase. Picture with good S/N ratio can be
obtained even at high gain increase. Delicate gain increase in increments of 3dB can be performed up to +12dB
to get sensitivity suitable for the scene.
■
Fully Digital Support
• Use of Digital Process LSI (ASIC)
The HDL-45E/E1 uses digital process LSI (ASIC) with max. 38-bit internal processing (calculation) used for our
broadcasting studio HDTV camera. Nonlinear processing such as white shading correction and gamma correction
which is digitalized in the camera implements consistently stable high picture quality and high reliability.
• 14-bit A/D converter
The HDL-45E/E1 uses 14-bit A/D converter to obtain picture with broad tonal range from dark part to highlighted
part. In particular, more natural “black” can be reproduced with higher tone of the dark part to which gamma
processing is performed.
