Abstract
The magnifying observation apparatus includes an imaging section for photographing an observation image, a display for displaying the observation image based on an image signal acquired with the imaging section, and a controller. The controller performs signal processing on an image signal and detects edge information on an edge contained in the observation image. The controller also extracts an edge section on the periphery of the points indicated with a point indication section and performs predetermined image processing on the edge section extracted. The display displays the resulting edge section over the observation image.
Claims15
A magnifying observation apparatus comprising:
- an imaging section for photographing an observation image;
- a display section for displaying the observation image based on an image signal acquired with said imaging section;
- an edge detection section for performing signal processing on the image signal acquired with said imaging section and detecting edge information on an edge contained in the observation image;
- a point indication section for indicating an arbitrary point in the observation image displayed with said display section;
- an edge extraction section for extracting an edge section on the periphery of the point indicated with said point indication section based on the edge information on the observation image;
- and
- a highlight section for performing predetermined image processing on the edge section extracted with said edge extraction section and displaying the resulting edge section over the observation image.
A method for observing a magnified image which uses a magnifying observation apparatus comprising an imaging section for photographing an observation image and a display section for displaying the observation image based on an image signal acquired with said imaging section, said method comprising:
- performing signal processing the image signal acquired with said imaging section and detecting edge information on an edge contained in the observation image;
- indicating an arbitrary point in the observation image displayed with said display section;
- extracting an edge section on the periphery of the point indicated based on the edge information on the observation image;
- and
- performing predetermined image processing on the edge section extracted and displaying the resulting edge section over the observation image.
A computer-readable medium storing instructions for operating the magnifying observation apparatus an imaging section for photographing an observation image and a display section for displaying the observation image based on an image signal acquired with said imaging section, said instructions comprising;
- performing signal processing the an image signal acquired with said imaging section and detecting edge information on an edge contained in the observation image;
- indicating an arbitrary point in the observation image displayed with said display section;
- extracting an edge section on the periphery of the point indicated based on the edge information on the observation image;
- and
- performing predetermined image processing on the edge section extracted and displaying the resulting edge section over the observation image.
