Abstract
An autostereoscopic display in which image data, in the form of grey level information for red, green, and blue components of pixels in multiple images representing multiple perspective views of a scene, are recombined into a second set of images generally consisting of parts of all the original multiple perspective images, arranged within the second set of images in such a way that a 3D image is seen when the second set of images are displayed in sequence.
Claims12
A method of displaying time multiplexed autostereoscopic images from a plurality of perspective views, each perspective view being an image of a scene from a position spaced along a line, on an autostereoscopic display of the type comprising an image-forming LCD having pixel elements in rows and columns and diagonal lines and a backlight having a plurality of sets of light lines oriented along the diagonal lines of the pixel elements of LCD, the backlight being arranged such that light from the light lines passes through diagonal lines of pixel elements of the LCD to a viewer, the method comprising the steps of:
- a) disassembling each of the plurality of perspective views into diagonal columns of pixel elements,
- b) reassembling the pixel elements from the views into a plurality of fields, each field comprising diagonals of pixel elements selected from all of the original perspective views;
- c) illuminating the sets of light lines of the backlight in a pattern;
- and
- d) displaying the plurality of fields on the LCD, such that the diagonals of pixel elements of the plurality of fields are displayed in synchronization with the pattern of illumination of the sets of lines of the backlight.
A method of reducing theater marquee effects on an autostereoscopic display of the type comprising an image-forming LCD having rows and columns of pixel elements, the LCD being illuminated by a backlight having a plurality of sets of light lines, each set of light lines being separately controllable, the method comprising:
- a) displaying a plurality of images on the LCD;
- b) illuminating the sets of light lines of the backlight in a pattern, such that the pixel elements of the plurality of images are displayed in synchronization with the pattern of illumination of the sets of lines of the backlight;
- the pattern of illumination of the light lines of the backlight being chosen such that the sets of light lines are illuminated in an order other than sequentially from one side of the display to another.
An autostereoscopic display producing a plurality of perspective views to a viewer at a distance, comprising:
- a) an autostereoscopic display;
- b) a source of a plurality of recorded images, each recorded image comprising a three dimensional image having a depth;
- c) a controller coupled to the source of recorded images and the autostereoscopic display, the controller being programmed to select a three dimensional image having a determined depth from the source of images and to display the three dimensional image on the autostereoscopic display;
- d) a distance detection device, having a sensor for detecting the distance of a viewer in front of the display and a signal output coupled to the controller, such that the controller can determine the distance to the viewer from the signal output of the distance detection device;
- e) the controller being programmed to select a three dimensional image having a depth based upon the distance to the viewer determined by the distance detection device.
A method of adjusting the depth of images displayed upon an autostereoscopic display producing a plurality of perspective views at a distance from a viewer, comprising:
- a) a distance determining device determining the distance from the viewer to the display;
- b) a controller selecting a three dimensional image having a depth from a source of a plurality of recorded images, each recorded image comprising a three dimensional image having a depth, based upon the distance to the viewer determined by the distance detection device.
