摘要： Embodiments of the present invention provide for hiding information in an image. A first pixel point and a second pixel point that are adjacent in an image are extracted. A first sub-pixel of the first pixel point and a second sub-pixel of the second pixel point that are to be combined during display on a display device are determined, wherein the display device determines a combined pixel value according to pixel values of the first sub-pixel and the second sub-pixel in a predefined manner. Information is hidden using parity properties of a sum of pixel values of the first sub-pixel and the second sub-pixel while the combined pixel value determined according to pixel values of the first sub-pixel and the second sub-pixel in the predefined manner is kept unchanged. By using unique display characteristics of a display device, information is hidden in an image without changing display effect of the image on the display device.

摘要： A method, system, and computer product for driving a display system in a screen protection mode includes receiving one or more image data, generating a first image signal and a second image signal based on the one or more image data, responsive to receiving an input indicating a screen protection mode, displaying a first image on a display screen of the display system based on the first image signal, displaying a second image on the display screen based on the second image signal, and passing through the first image by a viewing device and blocking the second image by the viewing device, so that a viewer wearing the viewing device indentifies the first image. Left-eye and right-eye lenses of the viewing device are configured to operate in a same manner.

摘要： Removing an embedded barcode in an image. A barcode-embedding area in an image is acquired. Pixels in the barcode-embedding area can be changed from a RGB color space to a color space with a luminance component. The luminance values of the pixels can be determined on a dark side or a light side. The luminance values of the pixels on the dark side or the light side can be mapped to luminance values falling into a whole range of a luminance interval. The pixels in the barcode-embedding area can be changed from the color space with the luminance component to the RGB color space.
