Definitions

  • the present invention relates to determination of condition of an electronic device comprising a screen, more particularly identification of one or more cracks on a screen of an electronic device.
  • Electronic devices such as mobile phones, smart watches, tablets, etc. have a significant screen component (of size and value) via which a user interacts with the device. Apart from the screen of being of considerable value, it also has an aesthetic factor that plays a major factor in valuation of the device itself, particularly when the user wants to sell or exchange the device. Evaluation of the screen (for cracks), which can deleteriously affect the imputed value of the device is typically done manually, sometimes by trained personnel. However, such valuation when carried out by humans, even if trained, can be highly variable, potentially leading to loss of value and/or opportunity for both seller and buyer. Such valuation also requires physical presence of the user.

Description

CRACKED SCREEN DETECTION SYSTEM AND METHOD
FIELD OF INVENTION
The present invention relates to determination of condition of an electronic device comprising a screen, more particularly identification of one or more cracks on a screen of an electronic device.
BACKGROUND OF THE INVENTION
The following description of related art is intended to provide background information pertaining to the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is to be used only to prepare the mind of a reader with respect to the general art, and not as admission of prior art.
Electronic devices such as mobile phones, smart watches, tablets, etc. have a significant screen component (of size and value) via which a user interacts with the device. Apart from the screen of being of considerable value, it also has an aesthetic factor that plays a major factor in valuation of the device itself, particularly when the user wants to sell or exchange the device. Evaluation of the screen (for cracks), which can deleteriously affect the imputed value of the device is typically done manually, sometimes by trained personnel. However, such valuation when carried out by humans, even if trained, can be highly variable, potentially leading to loss of value and/or opportunity for both seller and buyer. Such valuation also requires physical presence of the user.
There is a need in the art to introduce easy to use, quantitative, accurate, reproduceable and logic-based methods to evaluate the condition of a screen of an electronic device so as to maximize value, enhance efficiency, and which is not only reproducible, but also has a high degree of accuracy and cuts down instances of cheating or gaming the system.
CN1026228548A describes a method of screen crack detection method and device, which depends on a server having prestored images of different screens of various brands of phones. US10127647B2 describes systems and methods for automated visual inspection and evaluation of electronic device screens, which depends upon edge detection algorithms.
CN206440635U describes a device for detecting cell phone screen crack that comprises a LED lamp. SUMMARY OF THE INVENTION
