  • Publication number: 20110299070
    Abstract: Methods and apparatus for standardizing quantitative measurements from a microscope system. The process includes a calibration procedure whereby an image of a calibration slide is obtained through the optics of the microscope system. The calibration slide produces a standard response, which can be used to determine a machine intrinsic factor for the particular system. The machine intrinsic factor can be stored for later reference. In use, images are acquired of a target sample and of the excitation light source. The excitation light source sample is obtained using a calibration instrument configured to sample intensity. The calibration instrument has an associated correction factor to compensate its performance to a universally standardized calibration instrument. The machine intrinsic factor, sampled intensity, and calibration instrument correction factor are usable to compensate a quantitative measurement of the target sample in order to normalize the results for comparison with other microscope systems.

  • Publication number: 20110228993
    Abstract: The invention relates to a system for automatically adjusting an exposure time to improve or otherwise optimize a dynamic range of a digital image. The system includes a camera configured to capture an image of a subject within the field of view at a first exposure time. The captured image is composed of multiple pixels, with each pixel having a respective intensity value. The system further includes a shutter or suitable control configured to control an exposure time of the camera. A controller configured to carryout the following steps including: (a) querying a frequency distribution of pixel intensity values; (b) determining an effective “center of mass” of such a distribution, or histogram, to determine an adjusted exposure time; and (c) capturing a second image of the subject at the adjusted exposure time thereby obtaining an image with an improved or optimal dynamic range.
