20100177189 | METHOD AND APPARATUS FOR CONTROLLING A MICROSCOPE - In accordance with the present invention there is provided a method for controlling a microscope to scan a microscope slide. By analysing an overview image it is determined quantatively which swathe contains the most image detail and an optimum scanning order can subsequently be determined relative to the swathe determined as having the most detail. By scanning the swathe with the most detail first a good focus characteristic can be established for a dynamic focussing system and prediction errors in the dynamic focus system are likely to be low when scanning subsequent swathes. | 07-15-2010 |
20090185758 | METHOD AND APPARATUS FOR FORMING A MULTIPLE FOCUS STACK IMAGE - A method of producing a multiple focus stack image of a target, the stack image comprising a plurality of images of the target, each image having a corresponding focal range or position, wherein the method comprises causing relative scanning movement between the target and an array of light detectors, the array being used to repeatedly receive image information from the target during the scan in the form of scan lines; and causing the relative focus between the target and the array to be modified between the said focal ranges or positions of the respective images during the scan so as to obtain scan lines corresponding to each focal range or position during the scan, thereby obtaining the images in the stack, wherein each image is formed from the image information obtained as scan lines at the respective focal range or position during the scan. The method is then further characterised in that the relative focus is cycled between two extreme focal ranges or positions during the relative scanning movement and at least one scan line is obtained at a focal range or position located between subsequent extreme focal ranges or positions during the scan, each scan line being used to form one of the images of the target | 07-23-2009 |
20090185167 | IMAGE SCANNING APPARATUS AND METHOD - An image scanning apparatus comprises a time delay integration sensor for obtaining first image information from a target and a scan device for causing relative motion between the time delay integration sensor and the target. The image scanning apparatus is characterized by detector array for obtaining second image information from a target, wherein the first image information corresponds to a first portion of light received from the target and the second image information corresponds to a second portion of light received from the target. | 07-23-2009 |
20090103798 | IMAGE GENERATION - A method of generating a digital representation of a portion of an object from sets of digital data defining the colour content of individually stored, overlapping swathes of pixels of an image of the object portion. The method comprises:
