On the very first image of black hole: Part II

Related to the first image of a black hole, I explained my opinion in my first post: On the very first image of black hole: Part I
Here I'll try to expand it with an example.
Assume you are trying to take a photo of a billboard far away. You have the information that there is only one word on the billboard. You are limited to digital cameras. If you use only one digital camera you will be able to only capture a very small area of the billboard. The red box in Fig. 1.

Fig. 1: A billboard far away, divided to 56 sections

It is obvious that if one uses 56 cameras and each pointed towards a specific section in Fig. 1, by combining all the captured photos, the real image of the billboard can be revealed. 

The main challenge in 'Event Horizon' project was that they have tried to capture the image of the billboard in Fig. 1 with only 8 cameras. This the area that has been captured: 

Fig. 2: Captured areas with 8 digital cameras

Consider the image of the black hole as a word. What has been done is that all meaningful words has been added to a database. With the characters obtained in Fig. 3, random words has been generated:
Fig. 3: Obtained characters with 8 cameras
Random words:
- Banejele
Brnersa
Bqnvsdf
Bvnoidas
Banejele
...
...
Bankrupt

Then these words have been tested with the database, and the word with a meaning has been selected as the image of the billboard (black hole). Which in this case the selected word, for instance, can be:
Bankrupt

What I'm tried to say is that the obtained final word, as the real image of the billboard, is completely related to our database. Here, as my database was an English dictionary, the word that obtained was Bankrupt, however the real image of the billboard is:
Fig. 4: The real image of the billboard

In conclusion, if one day you heard that the image of black hole is different from what you have seen today, dont be supersized.
