Abstract
The present invention relates to the field of digital pathology and in particular to whole slide scanners. Autofocus imaging can be performed by sampling a first number of pixels of an image sensor and sampling a second number of pixels of the image sensor, wherein the second number is between one quarter and three quarters of the first number. Thus, continuous autofocus for rapid light scanning may be provided using data from a single sensor based on sampling data along a tilt with respect to the optical axis.
