Abstract
A method for controlling pixel addressing of a pixel display device (10) to drive the display device as an N-view autostereoscopic display when a lenticular screen (15) is overlaid and image pixel data for N discrete views to be interlaced is provided. Based on data defining at least the lenticular screen lenticule pitch (pμ), the number of views N, and the lenticular screen position relative to the display device pixels (12), for each display pixel, a derivation is made as to which of the N views it is to carry. The corresponding pixel data for the assigned view is then selected as the display pixel data.
Claims11
A method for controlling pixel addressing of a pixel display device to drive the display device as an N-view autostereoscopic display when a lenticular screen is overlaid and image pixel data for N discrete views to be interlaced is provided, the method comprising the steps:
- obtaining data defining at least the lenticular screen lenticule pitch, the number of views N, and the lenticular screen position relative to the display device pixels;
- applying a predetermined algorithm to derive, from the obtained data and for each display pixel, which of the N views is to be carried;
- and
- for each display pixel, extracting the corresponding pixel data for the assigned view from the image pixel data provided.
A display configuration utility carried on a removable record carrier to be read by means for controlling display driver circuitry of a pixel display, the utility, when run, controlling pixel addressing to drive the display device as an N-view autostereoscopic display when a lenticular screen is overlaid and image pixel data for N discrete views to be interlaced is provided, the utility effecting the steps of:
- obtaining data defining at least the lenticular screen lenticule pitch, the number of views N, and the lenticular screen position relative to the display device pixels;
- deriving, from the obtained data and for each display pixel, which of the N views is to be carried;
- and
- for each display pixel, extracting the corresponding pixel data for the assigned view from the image pixel data provided.
Driver apparatus for generating a per-pixel drive signal for output to a pixel display device, said apparatus comprising an image data store coupled with display image formatting means, said display image formatting means extracting per-pixel data from the store and format said drive signal;
- characterized in that said apparatus is reconfigurable to drive the display device as an N-view autostereoscopic display when a lenticular screen is overlaid, said image data store holding pixel data for N views to be interlaced, and the display image formatting means having an input for receiving data identifying the lenticule pitch and position relative to the display device pixels, said display image formatting means deriving, for each display pixel, which of the N views is to be carried, and extracting the corresponding pixel data for that view from the data store.
