is there a handheld computer, that scans and recognizes chess-positions
by camera from screen or board and analyses them in real time
with Rybka or stockfish or other strong engines ?

maybe ChessOcr https://play.google.com/store/apps/details?id=com.kgroth.chessocr&hl=en

This app utilizes the camera to recognize Chess Diagrams in books using optical character recognition (OCR). It saves each recognized diagram in a pgn file, and also puts the most recent one in the clipboard as a FEN string.

I have not tried this, I noticed it a few months back whilst looking for something else. Maybe its not what your after though.

could you then feed the FEN directly to a strong engine on that handheld computer ?

or submit it via internet to another strong computer and fetch back its analysis (easily)

This app utilizes the camera to recognize Chess Diagrams in books using optical
character recognition (OCR). It saves each recognized diagram in a pgn file,
and also puts the most recent one in the clipboard as a FEN string.
You can then invoke a chess program like DroidFish, or SCIDOnthego directly
to analyze the position or do a data base search for games that contain this position.
For best results the diagram should take up at least half the camera view,
and the book be reasonably flat (there is some compensation for page warp).
It works best for cameras that have autofocus capabilities, and will not work as
well on cameras that can not autofocus. Also, some cameras are not very
sensitive to light and require bright background lighting, while others work well
even in low lighting conditions.
If the chess diagrams are not being recognized, then try setting the video resolution
higher than the default (say to 1280 x 720) and/or setting the ISO to a high value
instead of leaving it on auto. Also remember to keep the page as flat as possible
in reasonably bright light. A green box will appear around the diagram after one
successful recognition. By default two identical recognition of the same diagram
in a sequence are necessary (this can be changed in settings) for a final successful

Impressive & Useful I'm going to pay for the pro key to support this app.
I also have a FEATURE REQUEST to be able to scan an eBook that is
in PDF format and automatically capture and convert all board diagrams
from (start page) to (end page), or (diag x) to (diag y), or (all diagrams)
and place the PGN's in one file, as individual "games."
Each PGN should identify its diagram number and page number.
If possible, combine consecutive board positions into one PGN game.
If combined with Asim Pereira's Chess Book Reader, that would be the
"perfect storm" of a chess app. Can this be done? (I sent you an email.)

A unique and awesome app Been using this for months now. Being able
to capture book diagrams and instantly convert them to pgn files is extremely
useful for study. Thank you so much for creating this incredibly useful app!
-------------------------------------
Really useful app. I had some trouble with using the app and contacted the
support team. They responded promptly and pointed out the right way to
use the app. Sure, the app's user experience could be improved, but the
team's commitment to solving issues trumps that. Hence 5 stars
-----------------------------------
Thank you for improvements It works now on my phone. Thank you for this app.
It was very helpful
