Abstract
A system and method that determines a number of scan lines for each image of a view using a resolution of the recording media, a pitch of the lenticules and a number of views needed to minimize angular transitions between views. The viewing range is also increased by allowing the primary visual field to be offset with respect to the projection field of the lenticules such that the image lines can be positioned under lenticules adjacent to the lenticule projecting the image lines as the distance from a central viewing position increases.
Claims12
A method for creating, from image lines to be displayed, a depth display including an overlay having projection fields, comprising the steps of:
- (a) selecting a minimum viewing distance for the display;
- (b) selecting positions of the image lines with respect to corresponding ones of said projection fields responsive to the selected minimum distance wherein the image lines produce visual fields and said visual fields are offset with respect to the corresponding ones of said projection fields;
- (c) fixing the image lines in a recording media responsive to the positions;
- and
- (d) abutting the overlay to the recording media.
A depth image display, comprising:
- an overlay including a projection field;
- and
- a recording media abutting the overlay and including a visual field in which a plurality of image slices are fixed, the visual field being fixedly offset with respect to the projection field.
An apparatus for producing a depth image, comprising:
- image means for producing image lines for the depth images;
- selecting means for fixedly positioning the image lines responsive to a minimum viewing distance;
- and
- display means for displaying the image lines responsive to the fixed positions through a depth image overlay, wherein said display means includes:
- a projection field for projecting the image lines;
- and
- a visual field for fixedly recording the image lines, said visual field being offset with respect to the projection field responsive to the positions.
A method for selecting lenticular pitch for a desired viewing distance of a lenticular image, comprising the steps of:
- (a) selecting a nominal lenticular pitch from a number of views and printer resolution;
- (b) selecting an offset from the nominal lenticular pitch, lenticule thickness and a refracted angle;
- and
- (c) selecting a lenticular pitch from the nominal lenticular pitch and the offset.
