UNIQUE DIGITAL IMAGING METHOD EMPLOYING KNOWN BACKGROUND

摘要

A method for using an image sensor includes steps that permit the calculation of a resolution of the image that is greater than the designed resolution of the image sensor. A specimen is placed onto a known background within the field of view of an image sensor having multiple pixels. The specimen is focused onto the image sensor in a first position relative thereto such that the known background is also focused on the image sensor. An image is recorded for the specimen and the known background focused on the image sensor in the first position, and a specimen region and background pixels are established from the image recorded. The specimen is moved to a second position relative to the image sensor so as to place a portion of the specimen region within a target background pixel. An image is recorded for the specimen and the known background focused on the image sensor in the second position, and the bit depth is calculated for the portion of the specimen region moved into the background pixel.
