Abstract

The invention discloses a safety information display system and a safety information display method based on spatial-domain psycho-visual modulation. A composition basis set is displayed in an spatial-domain arrangement by a display device, and if the composition basis set directly enters human eyes without being subjected to spatial-domain modulation, interference information/images can be fused; but when the composition basis set is viewed by a person via an auxiliary viewing device matched with the display device, the auxiliary viewing device can filter the interference information and display required true information/images, and accordingly, a safety information display function of the auxiliary viewing device is achieved. Due to the fact that resolutions of existing displays are increased increasingly and resolving power of the human eyes is limited within a certain distance, the display device and the auxiliary viewing device matched with the display device are adopted to perform specific spatial-domain psycho-visual modulation on information to be displayed, private information can be displayed to a user wearing the auxiliary viewing device, users with naked eyes can only view interference images on a screen, and practical application of safety information displaying is achieved.

Description

technical field [0001] The invention relates to a system in the technical field of signal and image processing, in particular to an information security display system and method based on airspace psychovisual modulation. Background technique [0002] With the rapid development of display technology, display devices have been popularized from household TVs and computer screens to mobile phones and tablet screens. Information display has been integrated into people's daily work and life and has become an inseparable part. However, the privacy issues posed by information display have raised concerns. In some public places with dense crowds, when using mobile phones, tablet computers, laptops and other devices, due to the large screen, it is very easy for others to see the private information presented on the screen. Therefore, a method for information security display is extremely important. [0003] Existing information security display solutions include WO 2012033583 A1 p...
