Title:
DETECTION METHOD AND APPARATUS FOR USE WITH DISPLAY SCREEN
Document Type and Number:
WIPO Patent Application WO/2018/187989
Kind Code:
A1
Abstract:
A detection method and apparatus for use with a display screen. The method comprises: configuring the brightness of a display screen to be detected as a preset brightness value, and self-adaptively adjusting a light sensing value of a camera according to the preset brightness value; according to the light sensing value of the camera, collecting images which are displayed on the display screen to be detected to obtain a plurality of collected images; calculating a degree of variation for each image point of the plurality of collected images in the spatial domain to obtain a differential graph of the collected images; detecting at least one detection item in the differential diagram of the plurality of collected images; carrying out determination on a result of at least one detection item by using a fuzzy logic determination method to obtain a detection result for the display screen to be detected. The detection method overcomes the problem in the existing technology wherein efficiency is low when manually carrying out detection on a screen, and increases efficiency in detecting the display effect of an electronic device to be detected.
