Depth of focus

The imaging depth ( in English Depth of focus) is the region in the image space of an imaging optical system in which a sufficiently sharp image of a focused object is created. It is also called depth of field. In the photograph is with imaging depth and depth of field depth of field called ( in English Depth of field), none of the terms can prevail there.

This means that the image plane (an image sensor, a photographic film ) can be moved in the field of imaging depth, without the image of an object is significantly blurred. The imaging depth is thus the counterpart to the depth of field is, because this is the area in object space, which is mapped with sufficient sharpness to the image plane.
