Abstract
Systems and methods for detecting and mitigating a contaminant on a display are disclosed. In an aspect, a mobile device may scan the display. The mobile device may generate one or more images related to the contaminant based on the scanning. The mobile device may detect the contaminant on the display based on the one or more images. The mobile device may identify the contaminant on the display using the one or more images. The mobile device may perform a mitigation action to mitigate the contaminant based on the identification of the contaminant.
Claims29
A method of mitigating a contaminant on a display of a mobile device, the method comprising:
- scanning the display using a scanner in the mobile device;
- generating one or more images of the contaminant based on the scanning;
- detecting the contaminant on the display based on the one or more images;
- identifying a type of the contaminant on the display using the one or more images;
- and
- performing a mitigation action to mitigate the contaminant based on the identification of the type of the contaminant including highlighting a contaminant area on the display, wherein the contaminant area contains the contaminant.
A mobile device, comprising:
- an ultrasonic scanner;
- a memory;
- and
- at least one processor communicatively coupled to the memory and ultrasonic scanner and configured to mitigate a contaminant on a display of the mobile device, the at least one processor, memory and ultrasonic scanner cooperatively configured to:
- scan the display;
- generate one or more images of the contaminant based on the scan;
- detect the contaminant on the display based on the one or more images;
- identify a type of the contaminant on the display using the one or more images;
- and
- perform a mitigation action to mitigate the contaminant based on the identification of the type of the contaminant including highlighting a contaminant area on the display, wherein the contaminant area contains the contaminant.
A mobile device configured to mitigate a contaminant on a display of the mobile device, comprising:
- means for scanning the display;
- means for generating one or more images of the contaminant based on the scanning;
- means for detecting the contaminant on the display based on the one or more images;
- means for identifying a type of the contaminant on the display using the one or more images;
- and
- means for performing a mitigation action to mitigate the contaminant based on the identification of the type of the contaminant wherein the mitigation action includes highlighting a contaminant area on the display and the contaminant area contains the contaminant.
A non-transitory computer-readable medium storing computer-executable instructions configured to mitigate a contaminant on a display of a mobile device that, when executed by the mobile device, cause the mobile device to:
- scan the display;
- generate one or more images of the contaminant based on the scanning;
- detect the contaminant on the display based on the one or more images;
- identify a type of the contaminant on the display using the one or more images;
- and
- perform a mitigation action to mitigate the contaminant based on the identification of the type of the contaminant including highlighting a contaminant area on the display,
- wherein the contaminant area contains the contaminant.
