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:

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.

I ordered mine from projectorpoint. The following websites are slightly cheaper:

Posting pictures is not straight forward, therefore I'll try emailing you tomorrow.

pigro, I have sent pictures to your email address.

many thanks AI - I'm much happier now I can visualise what real world performance is like! I was impressed not only by the clarity of the images on the screen in daylight but by the performance when projecting 52" onto a normal wall. Think I'll take the plunge ... Again, I really appreciate the time you've taken to help me out. One last thing ... did you try it with any video at all? If so, what was your subjective opinion of that?

03/16/06 + AI

Yes, I've tried video in similar way I tested still images. Infact I made three recordings to post but file sizes are very huge. Initial experience is as good as of single images. By the way I forgot to mention, the still images were via USB input. Also tried stand alone DVD player and camera input via composite connection. The quality is equally good.

Don't forget to tell us about your experinece and please update on this link. Thanks.

ordered at 1pm Friday, arrived at 11am Saturday (£12.50 extra charge but well worth it). Fantastic design, vey compact & functional. The reflective screen is very good even in bright daylight & at night in a dark room, the projected imageon a white wall was beter than expeced. Took a LOT of fiddling to manage to get it to display DIVX/DVD output from a Toshiba Sattelite laptop .... got there in the end though, and results very acceptable for such a small unit.

The remote control is not very responsive, I wonder is it the battery? Can other users please report.

03/19/06 + pigro

mine sems fine - even manages to operatemost of the time when usedfrom directly behind the projector. Range does seem a bit limited though ... if operating from ove 10 feet away I did find that it sometimes failed to detect input if not aimed in the general direction of the IR detector (on the front of the projector, near the lens)

03/19/06 + AI

Its working now, I was not pressing the buttons hard enough, they make a slight click while pushing down. How do you manage it to operate behind the projector when the IR senor is located in front, there has to be some kind of reflector?

03/19/06 + AI

Ignore the earlier query, the remote control is working fine even from behind the projector. Its size compliments project's compact design.

For those of you who already have an FF1 in hand, could you do a couple of simple tests to help me decide whether I should get one?

1.) what is the shortest distance from the wall that you can get a focused image at, and what is the horizontal or vertical screen size at this distance?

2.) what is the minimum distance at which you can get a 35-inch diagonal / 28-inch horizontal screen size?

Thanks for the help...

03/19/06 + AI

minimum projection size 11 inches at 40cm distance. For 35 inches projection the projector has to be 128cm away from the screen.

Are there any thin, flexible & small video cable available in the market? The one supplied with the projector is standard thick, rigid & heavy.

Just try google for thin or ultra-thin vga cable and you get a bunch. Like this:

Is that 11 inches horizontal projection size, or diagonal?
