Abstract: An image processing method includes: determining chrominance information and luminance information of an input color image; iteratively solving one or more equations to obtain bases of the luminance and modulation weights of a plurality of basis element frames of the input color image based on the luminance information; determining bases of the chrominance of the basis element frames based on the modulation weights and the chrominance information; and converting the bases of the luminance and the bases of the chrominance of the basis element frames into an output image.

Abstract: A video displaying method. The method includes applying a first frequency modulation in time domain on an original video thereby obtaining a first modulated video; applying a second frequency modulation in spatial domain on the first modulated video thereby obtaining a second modulated video including a first invisible-light image; and displaying the second modulating video with a corresponding frame rate. A time-domain frequency of the first invisible-light image is in a first range unrecognizable by a naked eye and recognizable by a video recorder. A spatial-domain frequency of the first invisible-light image is in a second range unrecognizable by the naked eye and recognizable by a video recorder.

Abstract: A display method includes: processing a plurality of images to form base compositions; and presenting the base compositions with different images in a spatial arrangement which as a whole form a composite image viewable to a naked-eye viewer; wherein a subset of the plurality of images are selectively viewable as a modulated view to a user with an optical modulation device.
