Abstract
A method for operating a surgical microscope having a camera is described. The method includes the following steps: a code that is able to be captured in a set frequency range is introduced into the field of view of the camera, at least one image which includes the code is captured via the camera, an evaluation device is used to identify the code and compare the latter to set features of a code required to activate at least one function, and if the identified code has the set features, the activation of the function is authorized.
Claims11
A method for operating a surgical microscope having a camera and an evaluation device as integral components of the surgical microscope, the camera being connected to the evaluation device to facilitate data transmission therebetween, the method comprising:
- introducing a code that is able to be captured in a set frequency range of 400 to 1000 nanometers directly into a field of view of the camera;
- capturing at least one image which includes the code via the camera by scanning the image which includes the code;
- identifying the code via the evaluation device;
- comparing the identified code via the evaluation device to set features of an activation code required to activate an operating function of the surgical microscope;
- thereafter, one of the following applies:
- i) if the comparison shows that the identified code has the set features of the activation code, an activation of the operating function of the surgical microscope is authorized via the evaluation device;
- or,
- ii) if the comparison shows that the identified code does not have the set features of the activation code, the activation of the operating function of the surgical microscope is disabled;
- activating the operating function associated with the activation code in response to authorization thereof;
- and,
- wherein the camera for facilitating said data transmission includes a device for text recognition and pattern recognition to facilitate reading out and identifying codes of different configuration including QR codes and/or data matrix codes and/or barcodes and/or serial numbers and passwords.
A surgical microscope comprising:
- a camera defining a field of view and being configured to capture an image including a code which is in said field of view, wherein the code is detectable in a set frequency range;
- an evaluation device connected to said camera to permit data transmission therebetween;
- said evaluation device being configured to identify the code and compare the identified code to set features of an activation code required to activate a function of the surgical microscope;
- and,
- said evaluation device being further configured to authorize an activation of the function of the surgical microscope if the identified code has the set features;
- and,
- wherein the camera facilitates said data transmission and includes a device for text recognition and pattern recognition to permit reading out and identifying codes of different configuration including QR codes and/or data matrix codes and/or barcodes and/or serial numbers and passwords.
