Resolution
With a typical 2 megapixel CCD, a 1600×1200 pixels image is generated. The resolution of the image depends on the field of view of the lens used with the camera. The approximate pixel resolution can be determined by dividing the horizontal field of view (FOV) by 1600.
Increased resolution can be accomplished by creating a sub-pixel image. The Pixel Shift Method uses an actuator to physically move the CCD in order to take multiple overlapping images. By combining the images within the microscope, sub-pixel resolution can be generated. This method provides sub-pixel information, averaging a standard image is also a proven method to provide sub-pixel information.

Famous quotes containing the word resolution:
“We often see malefactors, when they are led to execution, put on resolution and a contempt of death which, in truth, is nothing else but fearing to look it in the face—so that this pretended bravery may very truly be said to do the same good office to their mind that the blindfold does to their eyes.”
—François, Duc De La Rochefoucauld (1613–1680)
“A resolution to avoid an evil is seldom framed till the evil is so far advanced as to make avoidance impossible.”
—Thomas Hardy (1840–1928)
“It is a part of the American character to consider nothing as desperate; to surmount every difficulty by resolution and contrivance.”
—Thomas Jefferson (1743–1826)
