Thanks for the hint. A little bit of blur and resizing indeed helped.

With tessdata from [1] and oem 0 you can get:
tesseract unnamed.png - --psm 7 --oem 0
09:41 Dm
Otherwise:
tesseract unnamed.png - --psm 7
0%:41 pm
With small preprocessing (blur and resize, so letter have high around 30
points) you can get :
tesseract time.png - --psm 7
09:41 pm

I have this simple image with a date:
[image: test.png]
Tesseract produces the output:
*$ tesseract test.png -*
*Estimating resolution as 233*
*03:41 pm*
In similar images, I have the problem that it misunderstands 1's for 7's
and the other way around. How can I help Tesseract to recognise
