Lumagen Press Release:


Embargo release until January 6, 2011


RadianceMini 3D joins the award winning Lumagen® Radiance™ video processor family.

January 6, 2011 — Lumagen®, Inc., a specialist in the design and manufacture of video products for the home and corporate markets, is announcing the RadianceMini 3D. The RadianceMini 3D joins other members of the Radiance family, which includes the CEA® 2010 Platinum Video Product of the Year, the RadianceXE.

The RadianceMini 3D sports two HDMI® inputs, and one HDMI output, and can be controlled by either the included IR remote, or by RS-232. Control and setup are the same as other units in the Radiance family. In addition, it provides the same exceptional video quality that the Radiance line has become known for. The unit’s case measures in at a diminutive 8.5” by 5” by 1.05” (216mm by 127mm by 27mm) and has mounting tabs so it can be fastened to a shelf, or to the wall behind a flat-panel display.

HDMI 1.4 3D is supported, including scaling and aspect ratio control for 3D Bluray movies for use with an anamorphic lens, such as those produced by Panamorph®. For dual-projector 3D, two units can be used with each receiving 3D and outputting video for either the left-eye or right-eye.

Jim Peterson, Lumagen’s president, stated, “Our customers have been asking us for a new Radiance product optimized for small systems. The RadianceMini 3D fulfills this request, as well as the need for premier video processing when another product, such as an AVR, or HDMI matrix-switch, is being used for source selection.”

As with the other members of the Radiance line, proprietary No-ring™ scaling, linear-Gamma RGB-color-palette CMS, 21-point parametric grayscale calibration, video deinterlacing, MPEG artifact reduction, temporal noise reduction, and other features, combine to provide the best video quality available.

The RadianceMini 3D is currently available, and is priced at $1995 MSRP.

zbroke:

When the Mini is on if you press OK do you see the Info screen? If so, it might actually be HDMI cabling related. We have found that HDMI cables (and connectors) do show age sometimes. If you see the Status Screen look to see if HDCP is On for the input but Off for the output. This would say that an issue developed that the Mini cannot validate the projector HDCP. One thing to try is to (with all power in the theater disconnected) unplug and re-plug all the HDMI connectors a few times each. We have seen that this can help clean the contacts and restore operation in some cases.

If you do not see the status screen when you press OK, then it could be the power supply failing, or it could be the Mini. It takes less voltage from the power supply to light the LED, and it might not be enough to power the unit. You can measure the supply voltage under load by taking the cover off, and measuring from the back pin of the power connector to the case with a DC volt meter. It should measure about 5 VDC. You can purchase a new Power supply from us, or buy a 5 VDC (make sure it is NOT more than 5 VDC) at 4 Amps with a 2.5 mm positive center-pin barrel power connector, if it is the power supply.

It is possible a bit in the Flash ROM has "flipped" which can keep the unit from working. This is not common but can happen. If this is what happened, and the bad bit is not in the Boot Sector, you might be able to recover the unit with a boot-mode update as described in the TechTip that comes with the update.

If the issue is not resolved after trying the above, we would need you to send us the unit for evaluation.

Please continue this conversation by emailing support@lumagen.com so we can discuss further options.

I've never used the chromapure control panel. The Lumagen allows you to throw up any of it's own test patterns for greyscale, ie apl, small, medium windows or full field...or you can use external patterns. The multi-point gamma and greyscale is simple to understand and use. If you do a 10 point then move to 21 the scaler will interpoalte the new points to speed up the next fine tuning run.

You could ask lumagen direct but i don't see one on their site. I think i wrote somethign a few years ago but i can't find the link to it.

MENU 0910 turns on service mode and gets you access to the CMS stuff.

Choose the 10 or 11 point greyscale adjustment. and press OK

You will then see on screen data stating the control level, it's luminance, then R G B values.
If you adjust R G or B levels up or down you will see the Luminance level alter,,,ie add G and luminance goes up...to maintain gamma you then go back and move the luminance back to where you need it to be for your chosen gamma target and when you do that the R G B values will move either up or down relative to each other to maintain the correct greyscale. You may find that due to the non linearity of your display you need to iterate this bit a few times.

to change the pattern used press 4 to cycle through the options.

Sounds simple enough. Thanks!

I'm no Calibration Pro, but I find the Lumagen manual controls/menus easy to navigate. I do manual 21-point greyscale/gamma, and then let Chromapure loose to do the 125-point CMS. As Gordon said, it's quicker to do an 11-point initial run, then change to 21-point, and let the Lumagen do the interpolation, then fine tune the 21-point.
You will need to familiarize yourself with the menu structure, and the number values to change patterns, etc.
DON'T forget to Save, Save, Save, your changes.
Also, make use of the extra CMS memories to allow you to retain a previous 'good' cal, while trying something new in a 'clean' memory slot.

Regards, Mike.

I constantly forget to Save in ChromaPure. Wish there was just one save needed, at the end of the session.

need some help with mini

I am having a bit of a time figuring out the mini. My issue is video appears jumpy in some scenes specifically during some fast motion scenes. Do I have something out of sync here or is there a setting I need to look at in particular to avoid this problem?

Disable Signal Generator when operating the Radiance manually, otherwise the Cal SW will keep changing the patterns.

In Chromapure, the Gamma adjustment tab shows Gamma (obviously) but also shows the Reg-Green-Blue balance, so you can adjust Greyscale and Gamma together.

Adjust luminance, trim the RGB, re-adjust luma - repeat at each stimulus point.

I'm familiar with the gamma module in Chromapure, but what about in the Radiance? For example, at point 5 in the grayscale adjustments, the luminance is 40.2. Do I try to keep it there while I balance the RGB values?


EDIT: I notice from 60 to 100 IRE the luminance is 100.00. Should all intensity levels show the same luminance of 100.00?

If you have a Lumagen then i'd set 100 percent stimulus using the rgb gains in the display...If the low stimulus points are miles out you could try doing some small adjustments in the display for them with it's two point controls...but generally i'd just do 100 in display then do the rest with the Lumagen....

That must be my mistake there, I've been using the 10th interval of the panel's 10-pt white balance to set at 100.

Adjusted color points and saved in Lumagen, but post-cal looks identical to pre-cal measurement. The Mini3D was not connected to the laptop since I was using the Lumagen controls and remote. Must the computer still be connected to the vp?

Looks to me like you either didn't Save your settings or you measured the Reference test patterns, not the Adjusted test patterns from the scaler for your post charts.

Need some help!!! Ok so I recently got this lumagen mini and for some reason the only video output I can get is thru my xmbc player. My blu ray player nor western digital player will output ANY video. I can get sound to pass thru with no issues. Anyone have any suggestions Please? I know it is not the cable because when I run the same cable directly to the players I get video just fine..
 
#1,279 ·
ok well I was able to get video from my western digital player if I by-passed my receiver...there must be a setting I am missing in my pre amp.....hmmm

It all depends on the linearity of your display between the calibration points. Some displays will gain very little by going from 5x5x5 to either 9x9x9 or 17x17x17, but others will benefit. I believe Tom Huffman did some testing that gave a reasonable gain in performance going upto the 9x9x9, but the gains were really small going from there upto 17x17x17.

I would be interested in a Mini3D form factor containing the larger FPGA, that would allow for larger LUT calibrations.................................................

I would be interested in a revised firmware that swapped some of the (unused) CMS memories for one larger CMS memory. I mean do we really need 8 memories? I only use one (two if you count no CMS).

Seems my set is not so linear, the inside color points really benefit from 5x5x5 here...

Edit: actually spent about 40 minutes calibrating the grayscale manually in the Lumagen before realizing calibration reset was still active in Auto-Cal, LOL. Had to do it all over again after the LUT calibration was finished. Didn't really mind as my calibrating skills are improving.

How do I keep the Gray Window test patterns the same size in the Lumagen? When I press the 4 button on the remote and select continuous to adjust the grayscale levels, I get a white window, but when I take a single reading a smaller size white window pops up. I noticed using different size windows throws off the gamma setting at the higher end.

AV_Mike, I'm having the same problem as before, namely trying to use the Lumagen controls while the signal generator in ChromaPure is still active. How do you run auto-cal and still make manual adjustments with the Lumagen controls? Do you run 21-point grayscale calibration first? Then activate the signal generator in ChromaPure for auto-cal and 125-point lut?
