Abstract
A method and apparatus which provides alignment lines adjacent to a lenticular image. The alignment lines are projected through a lenticular overlay and used to align the overlay to the image. The alignment apparatus uses a light sensor and a computer to detect either changes in brightness or changes in a Moire pattern of the lines to effect rotational alignment and to detect either centeredness of the lines or brightness changes in the lines to effect translational alignment as the overlay is rotationally or translationally moved with respect to the print by the computer. An increase in brightness indicates motion toward either rotational or translational alignment. A constant brightness along the lines indicates rotational alignment while a peak in brightness indicates translational alignment.
Claims23
An apparatus, comprising:
- a recording media including an alignment line and an autostereoscopic depth image recorded therein;
- a overlay slidably positioned on said recording media to project the alignment line as a projected image;
- and
- positioning means positioning said overlay responsive to a characteristic of the projected image of the alignment line and aligning the depth image with the overlay.
An apparatus, comprising:
- a recording media including an alignment line and an autostereoscopic depth image recorded therein;
- an overlay slidably positioned on said recording media to project the alignment line as a projected image;
- and
- positioning means positioning said overlay responsive to a characteristic of the projected image of the alignment line and aligning the depth image with the overlay, said positioning means positioning said overlay rotationally and translationally responsive to the brightness of the projected image at two points along the alignment line.
An apparatus, comprising:
- a recording media including an alignment line and an autostereoscopic depth image recorded therein;
- an overlay slidably positioned on said recording media to project the alignment line as a projected image;
- and
- positioning means positioning said overlay responsive to a characteristic of the projected image of the alignment line and aligning the depth image with the overlay, said positioning means positioning said overlay responsive to a brightness curve of the projected image, positioning rotationally responsive to a shape of the brightness curve and positioning translationally responsive to a position of a peak in the brightness curve.
An alignable lenticular apparatus alignable with an overlay, said apparatus comprising:
- a recording media, said recording media including:
- a lenticular image fixed in the media;
- and
- an alignment line fixed in the media and adjacent to said image for aligning said media to the overlay.
An apparatus, comprising:
- a recording media including alignment lines and an autostereoscopic depth image recorded therein;
- a lenticular overlay slidably positioned on said recording media to project the alignment lines as a projected image;
- a light sensor sensing the projected image of the alignment lines;
- a positioning unit coupled to said overlay;
- and
- a computer, connected to said light sensor and said positioning unit, positioning said overlay into alignment with said recording media responsive to the projected image of the alignment lines and aligning the depth image with said overlay, the projected image including a Moire pattern when misalignment exists, the Moire pattern having a higher brightness level at two points along the alignment lines as rotational alignment is increased, the projected image including a continuous line pattern when in rotational alignment, the continuous line pattern having the higher brightness level as translational alignment is increased.
A method of aligning a recording media, including an autostereoscopic depth image, with an overlay, comprising the steps of:
- (a) fixing an alignment line in the recording media to project a projected image of the line through the overlay;
- (b) moving the overlay with respect to the media;
- (c) comparing the projected images of the line before and after moving;
- and
- (d) moving the overlay into alignment responsive to the comparison and aligning the overlay and the depth image.
A method of aligning a recording media, including a lenticular image and alignment lines, with a lenticular overlay producing a projected image of the alignment lines, comprising the steps of:
- (a) rotationally moving the overlay with respect to the recording media;
- (b) determining first brightness changes in the projected image at two points along the alignment lines during the rotational movement;
- (c) rotationally moving the overlay and the recording media image into rotational alignment responsive to the first brightness changes;
- (d) translationally moving the overlay with respect to the projected image;
- (e) determining second brightness changes in the projected image at the two points during the translational movement;
- and
- (f) translationally moving the overlay and the recording media into translational alignment responsive to the second brightness changes aligning the depth image and the overlay.
