It's a software issue with the app you are using to view the images. To check this, use the software to show you the resolution and then compare that to the resolution of the original images; they should be the same.

Now, if you right click on the images that show up pixelated and they have a much lower resolution than that of other images that show up fine, then the camera was set to a low resolution when the image was taken.

Also, check for a setting on previews within your software. Many apps will provide the user with the option to show low, medium or high quality previews. You may have your software set to low.

How did you transfer the images? If you used a program to do that, perhaps the program is set up improperly.

You should use a memory card reader that plugs in to a USB port, or; if your computer has a SD reader slot, use that.

What image viewer are you using? If using a Microsoft product, don't. Microsoft doesn't know how to make multimedia viewing programs. My favorite is JpegView. A bit hard to set up, but one of the better free image viewers for Windows. IrfanView is also a good viewer and easy to set up.

In your camera, you can bring up image information like the pixel dimensions of the image. Since you don't mention what camera you are using, you'll need to suss out if you have the camera set to maximum resolution. I'm pretty sure camera settings isn't the problem.

There could be one other thing, are you trying to view the image at more than 100% size? If so, you will see pixelation.

Consider not using the software provided by the manufacturer to import photos, and just copy the entire folder instead.

That shouldn't have happened if you did a straight-up copy.

Remove the SD card from your camera. Insert it to a USB card reader. Plug card reader to computer. Use Windows Explorer/File Manager or Finder to do the copying MANUALLY. That's it.

If you used an automated program (or script) (or app) to do it for you, there's the problem. Then, when working on the pictures, make copies first on a new directory and work on the copies. Keep also a complete set of copies on an external disk (be it a CD/DVD or a portable hard drive or USB stick).
