Method of tracking source display panel from which illegal copy of image is captured by camera and electronic apparatus for tracking illegal copy of image captured by camera from source display panel of electronic apparatus

An electronic apparatus for tracking an illegal copy of an image captured by a camera from a source display panel of the electronic apparatus, comprising:

• a source display panel;
• an integrated light emitting source;
• a memory;
• and
• one or more processors;
• wherein the memory and the one or more processors are connected with each other;
• and
• the memory stores computer-executable instructions for controlling the one or more processors to:
• generate a content image visible to human eyes using a visible light component integrated in the integrated light emitting source;
• generate a watermark image invisible to the human eyes in real time using an invisible light component integrated in the same integrated light emitting source;
• and
• simultaneously displaying the content image and the watermark image on the source display panel;
• wherein the watermark image comprises an image of an identifier unique to the source display panel;
• the image of the identifier unique to the source display panel is invisible to the human eyes and is recordable by the camera;
• and
• the image of an identifier unique to the source display panel is extracted from the image captured by the camera to identify the source display panel;
• wherein the electronic apparatus further comprises:
• an invisible light patterned film integrated on the source display panel, the invisible light patterned film comprising a first portion blocking the invisible light and a second portion allowing the invisible light to pass through, the first portion and the second portion forming a pattern corresponding to the invisible light emitting pattern;
• and
• a back light for displaying the content image, the back light comprising the visible light component and the invisible light component integrated therein;
• wherein the first portion and the second portion of the invisible light patterned film both allow visible light to pass through;
• and
• the invisible light is blocked by the first portion and passes through the second portion, thereby forming the invisible light emitting pattern containing the image of the identifier unique to the source display panel.
