Does anyone know any good program for filtering and sharpening pictures so I can zoom in picture and then filter it so i can see the smallest details on that picture. I really need it.

low rez pictures don't have the information you want, the best thing a program can do is guess. All it can do is remove some blending and colour leaks. The 1000x software-zoom and filtering you see in the movies doesn't really exist.

There must be some program that can do that. I guess that NASA have something to do that but probably it's not comercial program(they made it only for their needs).

Most programs have a LancZos algorithm for enlarging images. It's the best you'll get in normal circles. Sorry, I have no contacts at NASA

zoom right into an image so you have 10 or 12 pixels on the screen, then try to think how you would make those pixels into a high res close up of the image they are part of, if you can do that then you can retire right now, thats the sort of software every agency, astronomer, researcher and dreamer has been looking for, you only get it in bad Sci Fi movies, it isn`t possible, not even a bit, all software can do is try to guess, and at that it can be more wrong than a human doing the same thing.

the easiest way is to print it out at a colour print shop at the current resolution you have, then blowing it up on the printers photocopier, finally scanning it back in. you will lose a little bit of information but its the safest way to retain an image thats lost its detail. you really need to save your highest resolution image as a tiff or something thats not lossy.
there are some programs also that will allow you to take a snapshot of the screen at a higher resolution like crappy corel products, thats all there good for .
if your thinking about getting a 600 dpi reflection from someones eyeball from a lowres jpeg then you have been watching too much csi.
nasa does have some software that refines resolution but its hardly in your price range.

If no-one gives your an answer to a question you have asked, consider:- Is your question clear.- Did you ask nicely.- Are you showing any effort to solve the problem yourself 

The only really good program I've found for fixing focus blur and motion blur is Focus Magic.

Compare these two pictures of a spider I took this morning, the first is unprocessed, the second has been through focus magic.

If you know what they have and the name of that program just tell me.

Leave the price to me.

Nasa does have some software that corrects images, it isn`t a mattter of price, it does not do much more than Photoshop can do, but it does it to exact calibrations, so colours come out right and lighting can be corrected for, it`s meant to provide accurate pictures for geologists etc, it isn`t going to get a visible line of text out of a letter in the edge of a blurry webcam image, they send high resolution cameras to Mars for a reason, they want high resolution images, theres nothing in the world will actualy show you real detail where it isn`t, just stick it in photoshop and try edge detect or false colour filters, they often show up stuff you can`t see easily by eye, but you can`t get an image out of 40 blurred pixels, it just doesn`t work like that.

@Sirfire: see attached, same image, sharpen filter in freebie arcsoft photostudio that came with scanner, just does some edge detection and de-blurring by putting larger steps in colour range between pixels, doesn`t actualy add missing detail, just guesses.
