Image Quality and Color Management Technologies
in the LH Series LCD Monitors for Broadcasting Use

Image Quality and Color Management Technologies in the LH Series LCD Monitors for Broadcasting Use 3D-LUT / Matrix (two dimensions)

6-Poles (RGB/CMY) Coordinate Correction / 3-Poles (RGB) Coordinate Correction

Faithful Color Correction from the 3D-LUT

By using a three-dimensional LUT (Look Up Table) for each RGB color and applying precise 10 bit image processing, faithful colors are reproduced from low to high luminance levels and natural intermediate colors are attained. (more information)

I/P Conversion Circuit for Motion Response

A circuit delay time (not including panel delay) of approximately 5 msec* is achieved by incorporating an I/P converter circuit that converts SD and HD interlace signals with high precision to generate progressive signals without causing field-length delay. Minimizing the delay between the input signal and monitor output enables the user to confirm footage without any incongruity.

Diagonal Line Compensation

Jagged noise on diagonal lines in moving images is a common problem. This LCD monitor solves this by detecting correlations in the diagonal direction, resulting in smooth, precise reproduction of moving images.

Conventional Vertical Interpolation / New Diagonal Interpolation

Broadcast Settings for Gradation and Color Temperature

Individual RGB corrections are made on every monitor that is shipped, to ensure that rated gamma properties (g = 2.2) are reproduced, and gradation suitable for broadcasting is achieved. A color temperature of 9300 K/6500 K/5600 K, or 3000 K to 9300 K, can be selected with the variable setting.

WFM (Y/R/G/B) Display

The built-in waveform monitoring function displays a waveform in a sub-screen. The display signal can be selected from Y, R, G and B.

Vectorscope Display

All lines of the input signal via SDI are displayed as a vectorscope, and can be positioned in any of the four corners of the screen.

Various Markers

Various markers can be displayed in both 16:9 and 4:3 aspect ratios.
• Aspect Marker (16:9): 4:3, 13:9, 14:9, CNSCO2.39, CNSCO2.35, 2:1 or VISTA, with background brightness control of Black (0%), Half (50%) or Normal (100%).
• Safe Area Marker (16:9/4:3): 95%, 93%, 90%, 88%, 80% or VAR (variable setting).
• Center Marker (16:9/4:3): ON/OFF. The center marker can be displayed together with another marker, as shown in the example right.

Cross Hatch Overlay

A simple cross hatch overlay can be displayed to check the tilt of the camera.

Pixel-to-Pixel Display

This function lets you display and confirm video pixels without any resizing. When displaying 1080i/p, you can choose from five display areas: center, right-top, rightbottom, left-top or left-bottom.

Still Frame Display

A frame of video can easily be frozen and displayed as a still image on the left side of the screen. This function can be used to match a live camera with a frame of video shot at an earlier time or with a different camera.

Audio Level Meter

The color audio level meter displays the input level of embedded audio (SDI, HDMI*) or analog audio.* The display mode can be selected from 2-channel, 4-channel, 8-channel or OFF. It is also equipped with reference point setting, peak hold and over-range display functions.

Time Code Display

With HD SDI input, this function displays the value of the VITC, LTC or UB time code.

Closed Caption Display

The BT-LH1850 can display closed captions with an SDI or VIDEO input. It supports the EIA/CEA-708 HD SDI closed captioning standard (EIA/ CEA-608 SD-SDI closed captioning standard), and can display up to eight windows simultaneously.

HV Delay Display and Mono Mode

The HV Delay function that displays the video blanking period, and the Mono mode that switches the display to black-and-white, can be assigned to function keys for quick access.

RS-485 Serial Remote

Calibration Function

The BT-LH1850 comes installed with software that allows it to be calibrated without using a PC, by simply connecting a manufacturer-designated display color analyzer and measurement probe to the monitor.

Cine-gamma and Black Mode

The BT-LH1850 is equipped with a cine-gamma (F-REC) compensation function and serves as a monitor for the Varicam camera recorder. The black mode also makes dark image areas in low-gradation scenes easier to see. It helps to produce movies as well as film-like HD programs and commercials.

Function Keys

Each of the function keys on the front panel can be assigned a function selected from various display and switchover functions to enable one-touch display ON/OFF or mode change. These function buttons speed up operation and customize the functions to individual user needs.

SDI, HDMI and DVI-I Inputs

Two SDI inputs (SDI1/SDI2) with an automatic HD/SD switching function are provided as standard equipment. They support embedded audio, and the channel for audio output to speakers and headphone can be selected. The next-generation HD Link is featured to allow high-quality digital connection of a wide range of digital HD products with an HDMI terminal, such as BD/DVD players. Digital and analog DVI-I (Single Link) input is also provided.

Low Power Consumption and Mercury-Free Design Help Protect the Environment

A thorough energy-saving design has achieved low power consumption of only 22 W (with DC input), which is a 54% reduction from our previous model (the BT-LH1710 (2009 model) / Power Consumption 48W (DC IN)). A mercury-free LED backlight is also gentle to the environment.

Additional Features

• RS-485 (RJ-45), RS-232C (9-pin) and GPI (9-pin) remote input terminals.
• Tally lamp (red/green/amber).
• Key Lock function disables the front panel operation/control functions, except for Power switch, menu operation and sound level adjustment.
• Monaural speakers and headphone jack on the front panel.
• Fanless drive and its quiet operation make this model ideal for use in editing studios or MA rooms.
• Auto power down with no operation nor signal input for a certain period of time.
• Tilt Stand is included as standard (detachable).
