Abstract
A method of generating a digital representation of a portion of an object from sets of digital data defining the color content of individually stored, overlapping swathes of pixels of an image of the object portion. The method comprises: (a) selecting a portion of the object; (b) determining the swathes which contain pixels within the selected portion; (c) correlating adjacent ones of said swathes; (d) if necessary, adjusting the relative positions of the adjacent swathes in accordance with the results of the correlating step (c); and, (e) generating a digital representation of pixels of the selected portion from the correlated swathes.
Claims21
A method of generating a digital representation of a portion of an object from sets of digital data defining colour content of individually stored, overlapping swathes of pixels of an image of the object portion, the method comprising carrying out the following steps in a substantially continuous sequence:
- (a) receiving user input selecting a portion of the object and in response to the receiving user input performing the following steps:
- (b) determining ones of the swathes which contain pixels within the selected portion;
- (c) after the determining of the swathes at step (b), correlating adjacent ones of said determined swathes;
- (d) adjusting the relative positions of the correlated adjacent swathes in accordance with the results of the correlating step (c);
- (e) generating a digital representation of pixels of the selected portion from the correlated adjacent swathes;
- and
- (f) displaying an image of the selected portion using the digital representation generated in step (e);
- wherein the overlapping swathes of pixels are collected at a high resolution and stored prior to receiving, via user input, the selection of the portion of the object;
- wherein receiving user input selecting a portion of the object of step (a) comprises:
- producing a pre-scan of the object at a resolution lower than the high resolution, the lower resolution pre-scan being performed after collecting the overlapping swathes of pixels at high resolution;
- and
- wherein the correlating in step (c) is based on the high resolution data.
A method of generating a digital representation of a portion of a microscope sample, the method comprising:
- (a) receiving, via user input, a selection of a portion of one or more objects disposed on the microscope sample;
- (b) determining, out of a set of pre-stored swathes, ones of the swathes which contain pixels within the selected portion;
- (c) after the determining of the swathes at step (b), correlating adjacent ones of said determined swathes;
- (d) adjusting relative positions of said correlated adjacent swathes in accordance with the results of the correlating step (c);
- (e) generating a digital representation of pixels of the selected portion from said correlated adjacent swathes;
- and
- (f) displaying an image of the selected portion using the digital representation;
- wherein the pre-stored swathes comprise digital data defining pixel images of a plurality of overlapping regions of the microscope sample and the swathes are individually stored;
- wherein the pre-stored swathes are collected at a high resolution and stored prior to the receiving, via user input, the selection of the portion of one or more objects disposed on the microscope sample;
- wherein receiving user input selecting a portion of the object of step (a) comprises:
- producing a pre-scan of the object at a resolution lower than the high resolution, the lower resolution pre-scan being performed after collecting the overlapping swathes of pixels at high resolution;
- and
- wherein the correlating in step (c) is based on the high resolution data.
