JPEGs extracted from exe came PIXELATED

Hello,

This is a small 'OCR data editing 2.0.3' software(160kb), but it access a big file VBDL.exe (175mb) ... (some call it virus, but its not).
Its an image database. It contains about 798 jpeg files which is shown in the ocr software. Although, the jpgs are 576x1440 px long, it is shown partially & one has to scroll down.

Now, I was curious ...
So, I extracted the jpegs from that VBDL.exe - and they all came out Pixelated. (chk d scrnshots)

I used 2 software - JPEG Extractor & MultiExtractor, both produced same result.

But in the OCR software they look clean n good.

Why this is happening & how to resolve it ???
(Strangely, Photoshop CS5 can't able to open those extracted pixelate jps)
(Are they missing something? JPGs dont need codecs like videos. But in that case
I also tried to extract them while the software was running. But yielded same result.)

Also tell me what those controls for scrolling the jpg, in the ocr software called ??? (marked by red circle)
What is the difference between a scrolling window & those controls???


THNX in advance ...

That might be what is called PROPRIETARY FORMAT, which means, unless they'll give it to you (or at least the FORMAT DEF'S), you'd have to guess.

You can try using some data carving tools. For example, see: http://www.forensicswiki.org/wiki/Tools:Data_Recovery

I seem to recall having good experiences using Foremost. Give it a try.

Most are linux tools. If you have access to a linux box, great. Otherwise, there are usually binaries compiled to run under Windows using cygwin (link).
