IMAGE PROCESSING METHOD AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2017/045126
Kind Code:
A1
Abstract:
The present invention relates to an image processing method and a terminal. The method comprises: receiving display images frame by frame; determining shielding patterns on the basis of the display images, where each frame of shielding pattern shields a part of the corresponding frame of display image; determining output images by superimposing the corresponding shielding patterns on each frame of the display images, where every pixel of each frame of the display images appear at least once in N-frames of successively outputted output images, in the N-frames of successively outputted output images, the parts of the display images not shielded by the shielding patterns satisfy the principle of persistence of vision, and N is the number of frames of the display images outputted per second. Embodiments of the present invention, by providing the display images with the shielding patterns, are capable, on the basis of the frequency at which a terminal outputs a signal, in combination with the principle of persistence of vision, and insofar that user demand is satisfied, of protecting the display images of the terminal from being photographed unauthorized, thus ensuring the security of a user using the terminal.
