Abstract
A display signal conversion apparatus converts a first signal having a first color format and color arrangement into a second signal having a second color format and color arrangement. The display signal conversion apparatus includes a color conversion unit configured to convert the first color format into the second color format, a pattern determination unit configured to determine a signal pattern of the first signal, a unit configured to determine a color arrangement of a pixel position of the second signal corresponding to a pixel position of the first signal, and a sub pixel signal generation unit configured to generate a sub pixel signal having the second color format and color arrangement based on a result of the signal pattern determination and a result of the color arrangement determination.
Claims15
A display signal conversion apparatus for converting a first signal having a first color format and color arrangement into a second signal having a second color format and color arrangement, the display signal conversion apparatus comprising:
- a color conversion unit configured to convert the first color format into the second color format;
- a pattern determination unit configured to determine a signal pattern of the first signal;
- a unit configured to determine a color arrangement of a pixel position of the second signal corresponding to a pixel position of the first signal;
- and
- a sub pixel signal generation unit configured to generate a sub pixel signal having the second color format and color arrangement based on a result of the signal pattern determination and a result of the color arrangement determination.
A display signal conversion apparatus comprising:
- a unit configured to perform color conversion of an input RGB signal into an RGBW signal;
- a unit configured to determine a signal pattern of a two-dimensional position of one of the input RGB signal and the RGBW signal after the color conversion;
- a pattern determination unit configured to determine a sub pixel arrangement corresponding to a pixel position of an input signal;
- and
- a sub pixel signal generation unit configured to generate a sub pixel signal using a predetermined arrangement conversion based on a result of the signal pattern determination and the sub pixel arrangement determination.
