This is causing some of the tools and instructions for example, setting the Threshold level for the Wand tool to not function properly. The quickest way to fix this is to reinstall ImageJ to the Documents directory.

This is a grayscale satellite image of the area around Lake Mead, Nevada, taken by one of the Landsat satellites.
An important concept here is that storing all this information in an image file on your computer is much more efficient than it seems. To reconstruct the image correctly, the computer just needs to "know" the number of columns and rows in the image. This kind of grid of rows and columns is also called a raster , which is why this type of digital image is also called a raster image and why ImageJ is called a raster image processor.
So far, you know that a digital image is a string of numbers arranged in rows and columns. How does the computer know what each number should look like when it displays that pixel on your screen? It's pretty simple, really. In addition to a string of numbers, the computer has a "secret decoder ring" called a Lookup Table that it uses in paint-by-number fashion.
In an 8-bit image, the possible values correspond to colors. Okay, we know what you're thinking, but black, white and all those grays ARE colors!
The lookup table can be stored in the file with the data, or you can control it using the software that's displaying the data. This image is an 8-bit image. Each pixel is represented in the computer's memory by an 8-bit binary number, representing possible values from 0 to Another term for the number of binary bits used to describe the value of a pixel is bit depth.
You can think of the bit depth as the 3rd dimension of an image width and height are the other two. Download these versions to play on your computer. Your Account. Show me a movie of a quick tour of ImageJ.
