Abstract
The present invention relates to an image display method of displaying an image on a monochrome display having sub-pixel structure in a main pixel comprising the steps of: transferring digital image for displaying, by way of an interface for the digital data, image expressed by a number of steps of gradation of one sub-pixel being different from that of the other sub-pixel, using image data corresponded to the main pixel of the monochrome display; and reproducing the image data corresponded to a number of steps of gradation as same as a number of steps of gradation of said one sub-pixel, using the digital data for displaying the transferred image.
Claims20
An image display method of displaying an image on a monochrome display having sub-pixel structure in a main pixel each sub-pixel of which is capable of expressing multiple steps of gradation, comprising the steps of:
- forming from input monochrome image data for displaying said image on said monochrome display first image data for transfer, expressed by data of a predetermined number of steps of gradation and assigned to one sub-pixel in said main pixel of said monochrome display and second respective image data for transfer, expressed by data of a number of steps of gradation being different from said predetermined number of steps of gradation and assigned to the other sub-pixels in said main pixel;
- transferring all of said first image data for said one sub-pixel and said second respective image data for the other sub-pixels from a digital video card to a digital interface of said monochrome display;
- producing respective digital monochrome image data for display, expressed by data of an identical number of steps of gradation and assigned to each sub-pixel in said main pixel of said monochrome display using said first image data for said one sub-pixel and said second respective image data for the other sub-pixels transferred from said digital video card;
- displaying said image on said monochrome display using the thus produced respective digital monochrome image data assigned to each sub-pixel in said main pixel.
An image display apparatus comprising:
- a monochrome display unit displaying an image using digital monochrome image data and having a sub-pixel structure in a main pixel each sub-pixel of which is capable of expressing multiple steps of gradation;
- a digital interface unit by way of which said image data are input to said monochrome display unit;
- a data transferring unit including:
- a transfer data forming unit for forming from supplied input digital monochrome image data first image data for transfer, expressed by data of a predetermined number of steps of gradation and assigned to one sub-pixel in said main pixel of said monochrome display and second respective image data for transfer, expressed by data of a number of steps of gradation being different from said predetermined number of steps of gradation and assigned to the other sub-pixels in said main pixel;
- and
- a digital video card for transferring all of said first image data for said one sub-pixel and said second respective image data for the other sub-pixels from a digital video card to a digital interface of said monochrome display;
- and
- a display data producing unit for producing respective digital monochrome image data for display, expressed by data of an identical number of steps of gradation and assigned to each sub-pixel in said main pixel of said monochrome display using said first image data for said one sub-pixel and said second respective image data for the other sub-pixels transferred from said digital video card,
- wherein said image is displayed on said monochrome display using the thus produced respective digital monochrome image data assigned to each sub-pixel in said main pixel.
