Handtops, UMPC - LED Projectors by Mitsubishi, Samsung an

12/21/05 + AI

I posted a reply on the post link
But I thought it be appropriate to post it with a new title.

I have been keenly searching for Mitsubishi PocketProjector for the last six months and as most of us are perhaps aware that official release has also been postponed several times. From July to September, and now 19th Dec 2005. So I called up Mitsubishi and they regretted that it is still delayed.

Mitsubishi Taiwan Asia market is reporting 1Q 2006.

Samsung is also releasing its LED based projector called Pocket Imager (model SP-P300MK), due to be released next month (January 2006)

The Toshiba LED powered micro projector is out in France and it is to be released in UK around Christmas (or early New Year).
Find below the hyperlinks for detail perusal:

The images on this link are detailed however I believe the description in the article quoting 400 ANSI lumens is a mistake. Verify it with product release info from toshiba France website.

Those interested in checking out the projected images by Mitsubishi LED projector (model PK10 or PT10) and by Toshiba LED projector (model FF1) follow the links below:

The projected image by Toshiba FF1 is shown in the penultimate image on the link below. The attached battery is also visible.

The important question is ANSI Lumen and LUX values. Samsung states 23 ANSI Lumens while Mitsubishi and Toshiba indicates 250 and 400 LUX respectively.

Using the formula described on the following hyperkink:
link

My calculations for producing a projected image of 70cm(W) by 50cm(H), approximately 83cm(33inches) diagonal view:

Mitsubishi probably has 102 ANSI Lumens (calculated) and 250 LUX(stated) compared to Samsung having 23 ANSI Lumens(stated) and 55.9LUX(calculated). Whereas Toshiba’s LED projector is rated 400 LUX (stated) and 165 ANSI Lumens(calculated). I could have miscalculated, so verify with the formula! Please note that resolution 800 X 600 is 4:3 ratio or (1.34) therefore I choose screen size 70cmX50cm, ratio (1.4).

All three projectors have SVGA (800X600)native resolution. Weight wise Mitsubishi is the lightest 450 gm (without battery) and Samsung is the heaviest 660gm(perhaps without batter). The Toshiba is 556gm (without battery)

In my assessment Toshiba LED Projector is perhaps the best of the three. I have ordered mine.

Impressive review: it says absolutely nothing new over 4 paragraphs.

I think I know why the Mitsubishi was postponed for so long. The Viewsonic led projector is nothing else but the old Mitsubishi announced model.

Looks excellent, but notice its size and the special screen. The first image diagonal looks even smaller than 11''.

I don't think that the first image is demonstrating any projected image. May be the photo is taken to show projector with its specially designed screen. I am impressed with the second image because with so much ambient light in the environment, the image is bright enough to discern clarity. My understanding is that the designated screen area will give 28" diagonal projected image. If (hopefully) that comes out as bright and clear in that much ambient light I will be happy with my purchase as it will serve my purpose.

I think it is a projected image, probably defocalised though. What else could it be? The projection angle is consistent between the 2 photos.

The image looks good, particularly since it was captured on camera with ambient light. The exposure time was fairly short. It may look even better to the eye.

Even if the brightess would leave more to desire, I guess when the time will come (in 10000h or so) you could already change to better leds available by then. In two years they forecasted around 200lm!

Toshiba UK model's foldable screen looks smaller than the Japanese version. Am I right in my observation?

OQO should work with one of them and put an OQO inside. What a great little sales droid that would be.

I contacted the author of the report on the earlier link with two pictures of projected images by Toshiba LED projector. In his reply, he described that there was plenty of ambient light in the environment at Toshiba booth, light on the table, ceiling lights and daylight in the hall. In his opinion full size images projected on the foldable screen were bright and sharp and would not require the room to be dark. According to him Toshiba displayed projection upto 60” but that by darkening. While taking the photos, he also confirmed that the camera flash was off.

He explained that the projected images were small because there was little space between the projector and the screen, that’s why someone is holding the projector away form the table to increase the size. First projection is blank and second projection is from attached USB pen drive.

There was no information available on screen gain and actual lumen values from Toshiba representatives on the booth.

Has anyone considered the Viewsonic PJ106D ? - this one appears to be HD Ready - wouldn't this model be superior based on this?

The native resolution of Viewsonic PJ106D is also SVGA(800X600), same as PK10(Mitsubishi), SP-P300M(Samsung) and TDP-FF1(Toshiba). They are capable of receiving input signal from NTSC/PAL/SECAM, HDTV (from D-sub 15),VGA/SVGA/XGA/SXGA/UXGA, however the ouput will be SVGA i.e. 800X600 resolution.

Still no projector?

02/24/06 + AI

It is so annoying and I am completely miffed with the retailer in UK. Had I not paid the money I would have ordered it from somewhere else in Europe.

I shall be updating as soon it arrives.
