Image display device, image display system, image presenting method, and computer program

An image presentation method which separates and presents a plurality of images that are different from each other by an opening/closing operation of a shutter mechanism, the plurality of images being displayed by an image display apparatus having a display section that displays the images and a light source section that illuminates the display section, comprising:

• an image controlling step of switching and displaying the plurality of images that are different from each other every sub-frame period by the display section;
• a backlight controlling step of causing the light source section to alternate between a lighting operation and an extinguishing operation so as to include a lighting period within each sub-frame period;
• and
• a shutter controlling step of switching the shutter mechanism to an, open state in a period during which the light source section is extinguished, and switching the shutter mechanism to a closed state in a period during which the light source section is lit.

A computer program which is described in a computer-readable format so as to execute, on a computer, processing for separating and presenting a plurality of images that are different from each other by an opening/closing operation of a shutter mechanism, the plurality of images being displayed by an image display apparatus having a display section that displays the images and a light source section that illuminates the display section, the computer program causing the computer to function as:

• image controlling means for switching and displaying the plurality of images that are different from each other every sub-frame period;
• backlight controlling means for causing the light source section to alternate between a lighting operation and an extinguishing operation so as to include a lighting period within each sub-frame period during which the display section displays each of the plurality of images by time division;
• and
• shutter controlling means for switching the shutter mechanism to an open state in a period during which the light source section is extinguished, and switching the shutter mechanism to a closed state in a period during which the light source section is lit.

An image display apparatus comprising:

• a display section that switches and displays a plurality of images that are different from each other every sub-frame period;
• a light source section that illuminates the display section while alternating between a lighting operation and an extinguishing operation so as to include a lighting period within each sub-frame period;
• and
• a shutter control section that controls open/close timing with respect to a shutter mechanism for observing the plurality of images while separating the images, so that the shutter mechanism is switched to an open state in a period during which the light source section is lit, and is switched to a closed state in a period during which the light source section is extinguished.

An image display apparatus comprising:

• a display section that switches and displays a plurality of images that are different from each other every sub-frame period, for each of blocks obtained by splitting a screen into a plurality of parts;
• a plurality of light source sections that are provided for each of the blocks in the display section, and provide illumination while alternating between a lighting operation and an extinguishing operation;
• and
• a shutter control section that controls open/close timing with respect to a shutter mechanism for observing the plurality of images while separating the images, so that the shutter mechanism is switched to an open state in a period during which at least one of the plurality of light source sections is lit, and is switched to a closed state in a period during which the at least one light source is extinguished.
