Tesseract can't recognize simple numbers

enter image description here

$ tesseract pin3.png output
$ cat output.txt

// expect

I think the image is not complicated, but tesseract doesn't recognize the numbers of image. I thought perhaps number's colors are white, so I tried to change number color to black but result is same. How can I make tesseract recognize that kinds of image?

Thanks
