Methods and apparatus for displaying an image by uttilizing pixel sub-components which form a pixel element of an LCD display as separate luminous intensity elements. By treating the pixel sub-components independently, increased resolution is achieved in the dimension that is perpendicular to the dimension in which the screen is striped. To take advantage of the increased resolution, the image is processed by first scaling the image data in one dimension at a rate that is greater than the scaling of the image data in another dimension. The pixel sub-components are then independently determined from different portions of the scaled image data though scan conversion, which may involve the use of different weights for each color component. Color distortions such as color fringing is compensated by treating eachi pixel sub-component independently. For horizontally flowing text, applications, screens with vertical striping are preferred. |

DETAILED DESCRIPTION As discussed above, the present invention is directed to methods and apparatus for displaying images, e.
g.
, text and/or graphics, on display devices which are capable of utilizing multiple distinct sections of an output device, e.
g.
, the pixel sub-components of a liquid crystal display, to represent a single pixel of an image.
Various methods of the present invention are directed to using each pixel sub-component as a separate independent luminous intensity source as opposed to treating the set of RGB pixel sub-components which comprise a pixel as a single luminous intensity unit.
This allows for a display device with RGB horizontal or vertical striping to be treated as having an effective resolution in the dimension perpendicular to the direction of the striping that is up to 3 times greater than in the dimension of the striping.
Various apparatus of the present invention are directed to display devices and control apparatus which take advantage of the ability to individually control sub-pixel components.
FIG.
4 illustrates a computerized electronic book device 400 implemented in accordance with one embodiment of the present invention.
As illustrated in FIG.
4, the electronic book 400 comprises first and second display screens 402, 404 for displaying odd and even pages of a book, respectively.
The electronic book 400 further comprises an input device, e.
g.
, keypad or keyboard 408 and a data storage device, e.
g.
, CD disk drive 407.
A hinge 406 is provided so that the electronic book 400 can be folded protecting the displays 402, 404 when not in use.
An internal battery may be used to power the electronic book 400.
Similarly, other portable computer embodiments of the present invention may be powered by batteries.
FIG.
5 and the following discussion provide a brief, general description of an exemplary apparatus in which at least some aspects of the present invention may be implemented.
Various methods of the present invention will be described in the general context of computer-executable instructions, e
