LUM Coloring Exposure Check
http://www.flandersscientific.com/uploads/LUMColoring300.jpgThe LUM Coloring Exposure Check feature provides a false color map showing signal luminance levels on-screen. This feature can be turned on/off with a single button press allowing an operator to quickly and easily check exposure levels. In its default configuration this feature will show all levels above 100 IRE as white and all levels below 0 IRE as black. However, these thresholds can be quickly raised or lowered so that any luminance level can be set as a reference upper or lower threshold. A user defined center area can also be shown in greyscale instead of being color coded so that only levels between very specific upper and lower ranges will be highlighted in a false color. Also note that the Luminance scale can be changed between voltage, IRE, or Digital Levels depending on operator preference.
DSLR Zoom
The DSLR Zoom features allows for full screen scaling of DSLR video outputs when in preview or record modes, whether in 1080 or 480 resolution. Additionally, the DSLR Zoom feature works in conjunction with other features such as markers and scopes making FSI monitors an ideal complement to DSLR work-flows.

Focus Assist
http://www.flandersscientific.com/uploads/FocusAssist300.jpgThis feature provides you with a movable focus assist window that will highlight in focus areas within the window as red and will also provide you with a numerical indication of focus level. The focus threshold is adjustable so you can establish the level at which the red focus highlight will begin to appear. This feature in conjunction with the 1:1 pixel mapping feature provides operators with different methods for judging focus.
Measurement Feature
http://www.flandersscientific.com/uploads/measurement600.jpg
The measurement feature allows you to select any single pixel or block of pixels using a movable cross hair to obtain real time readouts of the YRGB values for that position. The YRGB values can be represented in the operator's choice of an 8 bit (0~255) or 10 bit (0~1023) range and will also be shown as a percentage value. Additionally, a reference position (both spatial and temporal) may be set, which then allows the cross-hair to be moved to any other onscreen position to obtain a real-time readout of the difference between the current and reference position values. The measurement feature also allows you to define any onscreen position (spatial and temporal) as your F Stop 0 reference and then quantifies the difference between your reference and current position as an F Stop value.
Timecode Display
http://www.flandersscientific.com/uploads/timecode200.jpgAll FSI Monitors are capable of pulling VITC 1, VITC 2, or LTC Timecode out of serial digital video and displaying it in any of 6 on-screen locations.
Pixel Zoom
This feature allows you select any portion of an HD signal and zoom in on it for a high quality closeup of just that portion of the signal. The Pixel Zoom feature works in real-time and plays video back without any additional delay even when in the zoomed mode.
Sub Window Freeze Frame
The sub window mode allows you to take any incoming signal and freeze it on the left side of the screen while keeping the video from that same input playing live on the right side of the screen. This mode is useful in matching different shots/scenes.
On-Screen Alarms
http://www.flandersscientific.com/uploads/IREAlarm200.jpgThe monitor can be setup to provide a small onscreen dialog box whenever a specified alarm condition is met. By default the IRE alarm will be triggered whenever signal luminance exceeds 100IRE, but this threshold level is customizable so that the operator can specify a different IRE trigger level for the IRE alarm. Additional alarms include RGB Alarm, Audio Mute, Loss of Signal, Black Field, and Blue Field. The advantage of the onscreen alarm system is that it allows operators to monitor a full video signal with no obtrusive overlapping Scope Windows becausethe alarm dialog box will only appear when an alarm event occurs.

这就是为什么我问LZ是不是一万美金的原因...
最接近LZ的预算的机器是惠普LP2480ZX，而且需要单独购买SDI输入端。 尊正在北京有点么？可否有现场展示看下效果？ 另外 我看尊正好像目前还没有可编程LUT的技术？
实际效果可能比较依赖面板批次吧 vvhh1234 发表于 2011-5-10 00:19 static/image/common/back.gif

如果没有3D LUT技术不可能把相当于NTSC 120%以上的色彩调整到 REC 709, SMPTE C, EBU, DCI-P3这几个色域范围中。即使是NTSC 72%的面板如果不进行3D LUT处理，也很难完全映射到REC709的范围内。

尊正在欧美市场其实是最早实现和倡导客户自己定期做监视器自动校正的厂商。也就是说不但每一台监视器都以CS-2000为标准在出厂前做了校正，而且，客户如果在具备专业仪器的前提下可以随时做自动校正，所以产品跟面板批次无关。
到目前为止，一些非常知名的厂商也仅仅能做白平衡校正而不是包括色彩、亮度、gamma、色温等全面校正。
以下是相关介绍的链接和部分介绍文字：

Calibration Workflow and Alignment Options
http://www.flandersscientific.com/main/templates/Basic4/black/bar.jpg
Offset Creation
High quality spectroradiometers offer unsurpassed measurement accuracy when dealing with a wide variety of spectral distributions. However, high quality spectroradiometers are very expensive and measure quite slowly compared to filter based colorimeters. Colorimeters measure very quickly making them ideal for full automatic alignment routines, but without specific offsets for any given spectral distribution can be quite inaccurate. Therefore, at FSI we have adopted a workflow where a high quality spectroradiometer is used as a reference device to which all colorimeters used for automatic alignment are first calibrated with individual offset files for every type of spectral distribution that may be encountered when measuring various FSI monitors. This workflow allows FSI to utilize several fast measuring colorimeters for calibration of new and serviced monitors while maintaining highly accurate measurement results.
FSI's Calibration Workflow
http://www.flandersscientific.com/uploads/calworkflow.jpg
http://www.flandersscientific.com/uploads/SpectroTable600.png
End User Recalibration Options
All FSI monitors come fully calibrated so there is no immediate need for calibration. Over time FSI’s customers have several recalibration options available to them and the recalibration option best suited to any particular customer is largely a function of the number of monitors owned and the specific application for which the monitor is being utilized.
[*]FSI offers FREE recalibration of your monitor as often as you like, for as long as you own the monitor, even outside of the warranty period. This is a service many other manufacturers and calibrators charge hundreds of dollars for and represents a significant cost savings to FSI monitor owners. Customers are only responsible for insured freight of the monitor to/from FSI’s service facility in Suwanee, GA, but the full recalibration procedure is performed at no cost. Typical turnaround for this service is within 24 hours of the monitor’s receipt at FSI provided that the monitor is sent into FSI with a valid RMA# issued by FSI’s service department. For customers that own only one or a few FSI monitors this is often the most cost effective recalibration option and ensures that your monitor is professionally recalibrated with the same high quality calibration tools used to calibrate new FSI monitors.
[*]FSI sells a CA-210 recalibration kitthat includes the DCAA (direct connect automatic alignment) adapter and a Minolta CA-210 colorimeter with preprogrammed recallable spectroradiometer offsets for all current FSI monitor models. The programmed offsets are determined for each individual Minolta CA-210 to ensure the greatest possible accuracy. This option is best suited for larger facilities that own many monitors and can justify the expense of a high quality colorimeter like the CA-210. FSI does not currently interface with any lower end colorimeters for automatic alignment as these cheaper probes tend to track poorly in lowlight measurements, even when offsets are used, making them unsuitable for an automatic alignment routine that measures dark test patches.
[*]Customers that already own a CA-210 colorimeter may purchase a DCAA adapter from FSI and send their CA-210 to FSI for calibration of recallable spectroradiometer determined offset files for every current FSI monitor model. Please note that a CA-210 should NOT be used for recalibration of FSI monitors unless it has the proper spectroradiometer determined recallable offsets programmed into the unit.
[*]In the USA FSI rents the CA-210 automatic alignment kit. This option is typically much more expensive than sending an individual unit in for recalibration, but for mid-sized facilities with 5 or more monitors renting an alignment kit may make sense both from a financial and convenience standpoint. This program is currently only available in the United States and rental kit availability is limited so customers must first contact FSI to schedule an open timeframe for rental. (This program will begin on a limited basis Summer 2011).
[*]All FSI monitors have a simple backlight adjustment that adjusts the unit’s peak white luminance. This is important because the main area of anticipated drift on FSI monitors over time will be the overall luminance of the displays. By simply increasing the backlight setting overtime to maintain consistent peak white luminance most other aspects of display performance will stay within very close tolerances of their original states. Though the x,y chromaticity and CCT readings of puck style colorimeters are generally very inaccurate the peak white luminance reading of a 100% white field is generally fairly accurate, even on lower end colorimeters. These inexpensive probes can therefore be used as basic light meters to maintain a desired luminance level over time. For many applications this adjustment alone will allow the monitor to operate within acceptable tolerance ranges.
[*]All FSI monitors are also equipped with basic RGB Gain/Bias controls that allow users with adequate test equipment, such as a high quality spectroradiometer, to manually tweak color temperature on the monitor. This is important because second to peak white luminance some slight drift in overall CCT (x,y chromaticity) is to be expected over time. This drift is typically not substantial, often times being less over the life of a unit than some CRTs would drift in a month, but the adjustments are there for customers interested in these manual tweaks to white balance over time. Customers using this approach should be aware of two important points:
[*]Only slight adjustment to RGB levels should be made. If substantial changes to RGB gain/bias are being used other aspects of calibration may be thrown off considerably. If such changes seem necessary then sending the unit in for complete recalibration may be advisable.
[*]The spectroradiometer used should be of sufficient quality and designed specifically to measure the type of display being calibrated. FSI recommends that spectroradiometers used for this purpose be at least 5nm bandwidth, have at least a 128 element detector, and utilize a high quality lens that allows for sufficient measurement area size at close measuring distances with minimal polarization error. Systems without traditional lenses, for example fiber optic based systems, are not recommended as polarization errors in readings can be significant with such systems on some LCD panel technologies.

^08^您多指教。
区别技监的重要的技术特征点 主要就是可编程LUT 因为有可编程LUT，相应的色彩管理解决方案才有意义，将校正好的色域数据定期修正，保证最佳的状态，或者是设置到其他的一些模式。
这种固定的3D LUT，对应的只是该面板批次的调整LUT 没有相应的色彩管理解决方案 使用上较受限制。 本帖最后由 vvhh1234 于 2011-5-10 01:40 编辑
看资料就头疼，直接回答问题不好么
用的是可编程LUT？可以自设目标模式么？这个自动校准是以什么为标准的呢？
面板依然决定产品，因为CS2000也没法解决面板均一性的问题 lcd有衰减的问题，3色rgb led背光，3色led分别衰减的速度不一样
另外多说一句。
FSI（尊正）的东西在欧美的口碑不错，奶牛上经常看到有人提起，参数上也很有性价比，尤其是售后30天不满意直接退货的条款。
大家确实可以考虑！
新的RGB LED型号也要出来了 很专业！在北京有点么？想去看看。 vvhh1234 发表于 2011-5-10 01:13 static/image/common/back.gif

V版意思是不是厂家在出厂时不会针对不同批次面板用编程LUT来映射色域设置为几种常用自动模式，专业器材的有名生产商在对零部件的测试把关上应该是苛刻的吧，用户自己针对硬件的具体情况使用编程LUT可能太不现实了，如果硬件本身没大问题和偏差，衰减的问题从外部控制的专业方法校正，跟映射色域是两回事了。 本帖最后由 vvhh1234 于 2011-5-11 15:26 编辑

其实不是，可编程LUT可不光是映射色域啊
比如IPS经常碰到的面板均匀性不好等本生问题，都可以通过它来解决。
开放模式还一个好处是使用色彩管理流程，不是色彩管理。比如CINETAL就是搭配CINESPACE来使用的
但也有些衰减是不好矫正的，RGBLED背光的面板想做到很好的效果就很难 实现可编程LUT不是很困难的事情，这个工作本身就在做，目前LUT的建立在工厂不是一个很友好的界面，如果开放，仅仅需要在PC环境下建立一个操作界面并开放给客户就可以了。事实上尊正在美国已经做过若干次LUT升级，客户使用升级线通过简单的操作就可以升级LUT。比如说现在尊正的LM-2461W就可以支持DCI P3、EBU、SMPTE C、REC709，如果客户需要也可以下载最新的CFE文件进行LUT升级。这里面的区别仅仅是CFE的生成是工厂做的还是客户自己做的。但是从产品后期维护的安全性和目前液晶面板技术能达到的技术高度综合考虑，暂时没有开放这部分功能。
另外，更大的问题是，不管是CINESPACE还是尊正的CFE都需要仪器的配合，这时候LUT的精确度已经完全依赖于仪器的精度了，这方面，CINETAL采用的是X-Rite和柯尼卡美能达的probe（探头），而尊正采用的是目前业界公认最好的柯尼卡美能达的CS-2000作为建立LUT的标准仪器。这方面让客户自己做并不现实，X-Rite本身就是比较偏民用的厂家，精度基本上没办法达到专业的要求，即使是eyeone pro也只是达到专业入门级别；而柯尼卡美能达的能做LUT的至少要CS-200以上，基于三刺激值的CA-210和CA-310根本无法完成这个工作，而CS-200大概要12万，CS-2000大概要24万。从经验来看，大部分液晶的背光衰减通过重新校正就可以达到较满意的结果，而没必要每次都重新生成新的LUT。 RGB LED的问题主要是面板均匀性的问题 之前LG的那块 自家用过 LP2480ZX也用过，都不可避免。
目前的技术能力想驾驭还是很难的 这种衰减很难矫正，面板的良品率就很低，尤其是在纯白下，近乎不可忍受，也是LP2480ZX让人质垢的硬伤
CINESPACE倒不是是给显示器，是因为支持一整套流程，在一套流程里软件硬件等之间的协同，和CFE关系不大吧。
主要的色彩管理流程就那么几个，如ARRI的一套，LIGHTSAPCE，CINESPACE。 本帖最后由 zun 于 2011-5-12 06:38 编辑

没错，尊正的LM-2470W用的也是相同的屏，的确是存在衰减很快的问题，这应该也是直下式RGB LED背光的主要问题。
cineProfiler是一定需要色彩分析仪的配合的，其实不管叫什么名字，核心技术其实就是如何建立三维色彩的映射关系，不管是液晶也好、等离子也好、OLED也好、投影也好，所有映射关系的建立一定需要一个反馈系统才可能实现。 可是之前的尊正我也看过，怎么没把好东西摆出来呢。 期待尊正在今年的birtv上多几个型号搞买一送一的好活动！！！ 还是瑞鸽监视器价格实在点，不知画在表现如何。
