Abstract
A head mounted display includes a first display unit for displaying an image of a center part of a display image and a second display unit for displaying an image of the outside thereof, and the images are combined by a half mirror for visual recognition. On the basis of the chromaticities of the first display unit and the second display unit measured by a chromoscope from a position similar to the viewpoint of a user, a calibration device calculates a color conversion matrix by which colors in a common color gamut are visually recognized, and outputs it in association with the display unit.
Claims12
A calibration device that performs calibration of a display device for individually displaying partial images obtained by dividing a display image into regions and combining them for visual recognition, the device comprising:
- a chromaticity information acquisition unit that acquires information of a chromaticity measured for each of a plurality of display mechanisms that displays the partial images;
- a color conversion matrix acquisition unit that determines a common color gamut included in color gamuts of the plurality of display mechanisms on a basis of the information of the chromaticity and acquires a color conversion matrix for converting pixel values of image data for each of the plurality of display mechanisms such that the partial images are represented by the common color gamut;
- and
- an output unit that outputs the color conversion matrix in association with the display mechanism.
A display device that individually displays partial images obtained by dividing a display image into regions and combining them for visual recognition, the device comprising:
- a color conversion matrix storage unit that stores a color conversion matrix for converting pixel values of image data in association with a display mechanism such that the partial images are represented by a common color gamut included in color gamuts of a plurality of the display mechanisms of display destinations;
- a color conversion unit that converts pixel values of data of the partial image by using the color conversion matrix associated with the display mechanism of the display destination;
- and
- an image output unit that allows the corresponding display mechanism to display the data of the partial image with the pixel values converted.
A calibration method of a calibration device that performs calibration of a display device for individually displaying partial images obtained by dividing a display image into regions and combining them for visual recognition, the method comprising:
- acquiring information of a chromaticity measured for each of a plurality of display mechanisms that displays the partial images;
- determining a common color gamut included in color gamuts of the plurality of display mechanisms on a basis of the information of the chromaticity and acquiring a color conversion matrix for converting pixel values of image data for each of the plurality of display mechanisms such that the partial images are represented by the common color gamut;

- outputting the color conversion matrix in association with the display mechanism.
An image display method of a display device that individually displays partial images obtained by dividing a display image into regions and combining them for visual recognition, the method comprising:
- reading a color conversion matrix associated with a display mechanism of a display destination from a storage unit for storing the color conversion matrix for converting pixel values of image data in association with the display mechanism such that the partial images are represented by a common color gamut included in color gamuts of a plurality of display mechanisms of the display destinations and converting the pixel values of the data of the partial image by using the same;
- and
- allowing the corresponding display mechanism to display the data of the partial image with the pixel values converted.
