EDOF – Extended Depth of Field

Clear images outside of normal depth ranges

Extended Depth of Field, also known as focus stacking, is a digital image processing technique which combines multiple images taken at different focus distances to give a resulting image with a greater depth of field (DOF) than any of the individual source images.

Focus stacking can be used in any situation where individual images have a very shallow depth of field. EDOF capture mode can take several pictures at different levels of focus and stack them into a clear image automatically with 1 click of the mouse. The EDOF images maintain the picture quality from its original pictures and can be stored and viewed in the DinoCapture 2.0 software.

*EDOF is only available with EDOF Dino-Lite models and while using DinoCapture 2.0 for Windows

EDOF can do more than Focus Stacking

Refocus Mode: By right-clicking your mouse, you can pick a different focal point in your image. This does not physically move your USB digital microscope out of position.

One-Touch Autofocus: Automatically focus and refocus as long as your subject is within focal range.

DPQ: Acquire depth information with compatible models. Users can acquire depth information from the focus shift between two focal planes during live imaging. Read about the compatible models and how to perform this process here or contact us for more information.
