Abstract
In a display controller, a standard information acquisition unit acquires at least one of a luminance characteristic and a color gamut of a standard display panel. A luminance information storage unit of an output adjustment unit stores a measurement value of a luminance characteristic of a panel of a displaying destination. A luminance range adjustment unit gradually adjusts a luminance range for an image to be a luminance range same as that of the standard display panel. A color gamut information storage unit stores a measurement value of a color gamut of the panel of the displaying destination. A color adjustment unit adjusts a pixel value of an image on the basis of the color gamut such that the image is displayed in a color same as that on the standard display panel.
Claims22
A display controller that controls data of an image to be outputted to a display panel, comprising:
- a luminance information storage unit that stores a measurement value of a luminance characteristic of the display panel;
- a standard information acquisition unit that acquires a luminance characteristic of a standard display panel;
- a luminance range adjustment unit that gradually changes a luminance range for the image on a basis of the measurement value such that the image is displayed within a luminance range of the standard display panel;
- and
- an outputting unit that outputs data of the image whose luminance range has been adjusted,
- wherein the standard information acquisition unit at least one of:
- (i) acquires a luminance characteristic determined on a basis of measurement values of luminance characteristics of a plurality of display panels, as the luminance characteristic of the standard display panel;
- and (ii) acquires a luminance characteristic of a display panel whose maximum luminance is lowest among a plurality of shipped display panels, as the luminance characteristic of the standard display panel.
A head-mounted display comprising:
- a display controller that controls data of an image to be outputted to a display panel and that includes a luminance information storage unit that stores a measurement value of a luminance characteristic of the display panel,
- a standard information acquisition unit that acquires a luminance characteristic of a standard display panel,
- a luminance range adjustment unit that gradually changes a luminance range for the image on a basis of the measurement value such that the image is displayed within a luminance range of the standard display panel, and

- acquiring a luminance characteristic of a standard display panel;
- gradually changing a luminance range for the image on a basis of the measurement value such that the image is displayed within a luminance range of the standard display panel;
- and
- outputting data of the image whose luminance range has been adjusted,
- wherein the acquiring includes at least one of:
- (i) acquiring a luminance characteristic determined on a basis of measurement values of luminance characteristics of a plurality of display panels, as the luminance characteristic of the standard display panel;
- and (ii) acquiring a luminance characteristic of a display panel whose maximum luminance is lowest among a plurality of shipped display panels, as the luminance characteristic of the standard display panel.
