Abstract: The invention relates to a method and an apparatus for generating a depth map from a digital monoscopic color image. The method includes the following general steps: a) obtaining a first color component of the MCI, said first color component corresponding to partial color information of the MCI; and, b) assigning depth values to pixels of the MCI based on values of the first color component of respective pixels for forming the depth map for the MCI. In one embodiment, the depth values are generated by adjusting and/or scaling of pixel values of the Cr chroma component of the monoscopic source color image in the Y?CbCr color system.

Abstract: A sign includes a housing, and at least one symbol plate that provides a visual representation of at least one symbol. A symbol plate attaches to the housing in at least two orientations relative to the housing. Optionally, a symbol plate has at least one cutout that provides the visual representation. Optionally, the housing includes a light source that emits light waves that pass through cutouts to illuminate visual representations. Optionally, a sign includes a sheet, disposable between the housing and a symbol plate, and adapted to filter at least one color from the light waves. The at least two orientations can include a first position, and a second position 90 degrees to the first position. Optionally, a sign includes a cover, or a cover and a deluxe plate, having at least one respective opening that exposes the visual representation.
