However, if you’re interested in capturing large images then 5MP or more is a benefit and allows printing of larger images and gives the ability to digitally zoom in. As a result most microscopes will default to a lower resolution such as 1.3 megapixel when used for live video imaging. The frame rate also slows down at high resolution making it less convenient in live imaging as large volumes of data are being transferred to the computer. 5 or more megapixels is great for capturing large images but rarely used in live video streaming as many computer monitors display no more than 2 megapixel (Full HD). Going for the highest the resolution (number of megapixels) USB microscope is not always necessary so it is worth considering carefully what resolution your application needs. Image Quality - It's not all about resolution!
