Abstract: 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.

Abstract: 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.
