B/P/D Series Monitor internally built in 3D-LUT Color Management System in accordance with unified industry standards and it uses professional testing equipment to take systematic and accurate calibration for monitors to ensure the display indicator of monitor meet the tolerance range of color space standard .Therefore, it ensures each monitor has the accurate color restoration and the color of same style monitors is consistent to the maximum extent .
Luminance levels can be represented using False Color on the screen. It represents the amount of exposure explained as color values ranging from Blue to Green to Yellow to Red.
Usage:
False Color is used to assist in setting the camera exposure. Blue (cool color) indicates a low exposure, a darker blue indicates an even lower exposure. Red (warm color) indicates a high exposure and a deeper red indicates an even higher exposure. Green and Yellow are in between. A scan feature allowing the image to be offset to the upper left revealing the Luminance Waveform on the upper right makes it easy to identify parts of the picture which may exceed standards.
The zebra is suggested that the photographic exposure is a highlight indicator, and the aperture can be controlled according to the zebra tips when shooting with a manual aperture.
Usually when the brightness of the subject exceeds the maximum brightness (different types of models) that the camera can accommodate (different, this value is different), the zebra is started, so, when the aperture is adjusted, the subject should be the brighteree Slightly with zebras, while other parts have no zebra, which can be accurately exposed. If the spot is too much, the exposure is excessive; if there is no zebra pattern any part of the image, the image will be insufficient. Now some cameras are adjustable, usually adjusted between 60% and 100% of the highest brightness, and can be selected according to their own habits.
Luminance Waveform
The luminance waveform can be superimposed over picture (see below). The Y-axis represents the luminance level. There are two indicators; one at 100% and one at 700mv.
Usage:
The Luminance waveform is mainly used to read the value of the Y signal. This is helpful for setting Camera Iris levels.
Audio Meter
16 channels of embedded audio in the SDI video signal can be decoded and 8 selective channels can be shown on the screen at the same time. The Volume unit shows both VU and PPM.
Usage:
The Volume unit is used for measuring audio levels and calibration. This is helpful for making sure that audio levels are within technical requirements and specifications.
Safe & Area Marker
Usage:
Image overflow or cutoffs can be checked using this feature. This is helpful during “Pan and Scan” as image is prepped for various broadcast markets. Ruige monitors have selections for Safety Marker Scales, Title Scales, Transform Scales and Center Cross. This is helpful for composition during shooting or title placement.
Usage:
In order to adjust for correct scanning users can choose different Aspect ratios. Selections are: 16:9, 4:3, Letterbox, Pixel-to-Pixel, Over Scan and Built-in Scan.
Only the blue portion of the video signal is displayed.
Usage:
This is used for monitor color phase adjustment, level and calibration
Usage:
Overscan is often used to programing for TV broadcast.

Rapid positioning for out of range indicator
“Exposure analysis” function gives the user the ability to do fast out of range checks. When the image becomes more complex with out of range colors, it becomes too inconvenient to see.
The design inspiration of this function is based on x-ray machines and body scanners at airports. The black color indicates hard items and the softer items are represented with White and purple. These colors can be isolated in one second by contrasting with “Exposure Analysis” when switched on.
Case in point, security checks at airport are lacking due to subjective human factors. With Rapid positioning for out of range indicator allows for 100% accuracy. However, the end user has the freedom to not use this function for that artistic professional look.
