  • Publication number: 20190371004
    Abstract: The present invention provides a method and system for determining skin color, method for generating an ICC profile and an image capturing device. The method for determining a skin color includes: providing an image capturing device including a light sensing module and a light distributing module, in which the light distributing module includes a light source and a light isolation tube, the light isolation tube has a first end connected to the light sending module and a second end away from the light source, the light source is disposed on the first end, and the second end has an opening; capturing a first image of an area under test of a human body using the image capturing device, wherein the opening adheres to the area under test such that the image capturing device forms a darkroom environment with respect to the area under test.

  • Patent number: 9600880
    Abstract: A method and system for qualifying a surgical clip applier with surgical clips are proposed. After successive firing operations of the surgical clip applier, an image capture unit captures sampling images associated respectively with angularly equidistant radial recesses in a rotatable clip-receiving disk for receiving anything fired from the surgical clip applier. Upon determining that each sampling image contains an individual target image portion showing a single fired surgical clip, a processing unit verifies the qualification of the surgical clip applier based on a predetermined specification and characteristic parameters obtained respectively from the individual target image portions and associated respectively with the surgical clips, which are received respectively in the radial recesses.
