Abstract
A system for displaying an image converts an input pixel data for output onto a display device of a different resolution. An apparatus outputs a plurality of first pixel data of the input resolution. A converting apparatus assigns at least one of a plurality of weighted values and partially amplifies the plurality of first pixel data to output a plurality of second pixel data. The display device is coupled to the converting apparatus to receive the plurality of second pixel data, and the display device displays the image of a second prescribed resolution based on the plurality of second pixel data.
Claims24
A system for displaying an image, comprising:
- an apparatus that outputs a plurality of first pixel data of a first prescribed resolution;
- a converting apparatus coupled to said system, said converting apparatus assigning a plurality of weighted values to said plurality of pixel data in a first direction and partially amplifying said plurality of first pixel data in a second direction to output a plurality of second pixel data;
- and
- a display device coupled to said converting apparatus to receive the plurality of second pixel data, said display device displaying the image of a second prescribed resolution based on the plurality of second pixel data, wherein the first and second directions are different directions, wherein said converting apparatus comprises:
- a data loading circuit coupled to said apparatus to receive the plurality of first pixel data;
- a conversion circuit coupled to said data loading circuit, which converts the plurality of first pixel data to the plurality of second pixel data;
- and
- a data output circuit coupled to said conversion circuit to receive the plurality of second pixel data for output to said display device, wherein each of said plurality of first and second pixel data comprises a prescribed number of bits, and said conversion circuit comprises:
- a connection circuitry coupled to said data loading circuit, said connection circuitry shifting the bits of corresponding first pixel data;
- and
- an arithmetic unit coupled to said connection circuitry, said arithmetic unit performs a prescribed arithmetic operation on the shifted first pixel data to output the plurality of second pixel data.
A converting apparatus for converting a plurality of pixel data for a first resolution to a plurality of pixel data for a second resolution of a display device, comprising:
- a data loading circuit to receive the plurality of first pixel data;
- a conversion circuit coupled to said data loading circuit, said conversion circuit assigning at least one of a plurality of weighted values and partially amplifying said plurality of first pixel data to output a plurality of second pixel data;
- and
- a data output circuit coupled to said conversion circuit to receive the plurality of second pixel data for output to the display device, wherein each of said plurality of first and second pixel data comprises a prescribed number of bits, and said conversion circuit comprises:
- a connection circuitry coupled to said data loading circuit, said connection circuitry shifting the bits of corresponding first pixel data;
- and
- an arithmetic unit coupled to said connection circuitry, said arithmetic unit performs a prescribed arithmetic operation on the shifted first pixel data to output the plurality of second pixel data.
A method of converting a plurality of pixel data for a first display having a first resolution to a plurality of second pixel data for a second display having a second resolution, the method comprising the steps of:
- (a) assigning a weighted value to the plurality of first pixel data in a first direction to output the plurality of second pixel data in a first direction of the second display;
- and
- (b) partially amplifying the plurality of first pixel data in a second direction to output the plurality of second pixel data in a second direction of the second display, wherein at least one of the steps (a) and (b) is performed by shifting the bits of corresponding first pixel data and wherein at least one of the steps (a) and (b) is performed by performing a prescribed arithmetic operation on the shifted first pixel data.
