How to Analyze Scanner Image Size in Pixels

When you are dealing with images that you have already scanned into your computer, you may notice that the scanner image is a bit distorted. It may either be too big or too small. Or, you may notice that your image is now composed of thousands of squares that are now making your image appear blocky. What you are seeing are pixels.

Step 1: Understanding Pixels

Whenever you scan an image, your computer has to work to change the image that it is seeing into information that the computer will recognize as the same image. The computer will break down your image into a set of columns and rows that have various colors assigned to them. These individual squares are called pixels.

Step 2: Using Pixels

It is important to remember that the larger the number of pixels, the more detailed and image is. This also means that if you want to enlarge an image, it will stay cleaner longer than a small image. When you create images, whether from a photograph or from a computer program, it is important to save the images with highest pixel count possible. 

Step 3: Scanning Your Images

When it comes to scanning you images, be sure that you know the dimensions, in pixels, that you are looking for.  When you scan your images, you can set the scanner to automatically enlarge the image to the proper pixel aspect. If your pixel count is small, say 300 x 300, then you will have a fairly small image, which you will not be able to enlarge. If you do, all of those individual pixels will become visible. It is always best to scan in your images at the highest pixel count, and then you can shrink down from there if need be.
