Here is the challenge description:

> A creaky old bot is zooming in and out of an eye chart. "Can you read the bottom line?" the doctor asks. "No way, " the bot replies. "At a certain distance my view becomes convoluted. Here, I'll make a screenshot." You and the doctor look at the screenshot. Can you tell what's wrong with the bot's visual processor?

### What are we working with?

We are given a PNG file which shows some distorted imagery for what looks like text:


Assuming that we need to 'deblur' the text to read it, I start looking online.

### Solution

Looking online for CTF image blurred I found [this resource](https://fareedfauzi.gitbook.io/ctf-playbook/steganography).

Scrolling through I found this entry: `13. Use SmartDeblur software to fix blurry on image.`

Downloading [SmartDeblur](http://smartdeblur.net/) I put the image in and try to automatically deblur it...


Well, that didn't work... Lets try some different settings.

I select a portion of the image and drop the size to 10x10.
