Abstract

An object of the present invention is to notify an observer who is wearing shutter glasses of information related to the remaining battery capacity or the like of the shutter glasses, through display of a stereoscopic image. To that end, shutter glasses (20) transmit internal information such as the remaining capacity of a battery (22) to a display apparatus (10). On the display apparatus (10) side, notification or warning of the remaining capacity is displayed on the screen by a display section (11). Of course, this notification or warning can be also presented as a time-division stereoscopic image. In such a case, the observer can check a state such as exhaustion of the battery (22) while keeping wearing the shutter glasses (20), that is, while viewing a stereoscopic image.

Claims

1. An image display apparatus comprising:

a display section that switches and displays a plurality of images that are different from each other by time division;

a communication section that communicates with shutter glasses driven by a battery; and

a control section that controls an apparatus operation,

wherein the communication section transmits information related to open/close timing of shutters to the shutter glasses, and receives state information of the battery from the shutter glasses, and

the control section displays a warning in the plurality of images on the display section, upon detecting a decrease in remaining capacity of the battery on a basis of the received state information of the battery.

2. The image display apparatus according to claim 1, wherein:

the communication section is capable of communicating with a plurality of pairs of shutter glasses; and

the control section displays visual information in the plurality of images on the display section, the visual information representing a state of the battery for each of the pairs of shutter glasses.

3. The image display apparatus according to claim 1, wherein:

the communication section is capable of communicating with a plurality of pairs of shutter glasses; and

the control section displays the plurality of images including display of the warning on the display section, only with respect to an observer wearing the shutter glasses for which a decrease in remaining capacity of the battery has been detected among the plurality of pairs of shutter glasses.

4. The image display apparatus according to claim 3, wherein

upon detecting a decrease in remaining capacity of the battery in any one of the plurality of pairs of shutter glasses with which the communication section communicates, the control section

inserts a frame including display of the warning into each of the plurality of images, and

transmits information related to open/close timing of the shutters from the communication section to other pairs of shutter glasses for which a decrease in remaining capacity of the battery is not detected, the information instructing that all of the shutters be kept in a closed state during a period in which the frame including display of the warning is displayed.

5. An image display system comprising:

shutter glasses each having a shutter mechanism provided in a lens, the shutter glasses being driven by a battery; and

a display apparatus that switches and displays a plurality of images that are different from each other by time division,

wherein the display apparatus transmits information related to open/close timing of shutters according to switching of the plurality of images, to the shutter glasses,

the shutter glasses perform an opening/closing operation of the shutters on a basis of the information related to open/close timing of the shutters received from the display apparatus, and transmit state information of the battery to the display apparatus, and

the display apparatus displays a warning in the plurality of images on the display section, upon detecting a decrease in remaining capacity of the battery on a basis of the state information of the battery received from the shutter glasses.

6. An image display method which displays an image on a display apparatus including a display section and a communication section, comprising:

a time-division image displaying step of switching and displaying a plurality of images that are different from each other by time division, by the display section;

a shutter controlling step of transmitting information related to open/close timing of shutters to shutter glasses driven by a battery, from the communication section; and

a controlling step of performing control so as to display a warning in the plurality of images on the display section, upon detecting a decrease in remaining capacity of the battery on a basis of state information of the battery which is received from the shutter glasses by the communication section.

7. A computer program which is described in a computer-readable format so as to execute, on a computer, processing for displaying an image on a display apparatus including a display section and a communication section, the computer program causing the computer to function as:

time-division image displaying means for switching and displaying a plurality of images that are different from each other by time division, by the display section;

shutter controlling means for transmitting information related to open/close timing of shutters to shutter glasses driven by a battery, from the communication section; and

controlling means for performing control so as to display a warning in the plurality of images on the display section, upon detecting a decrease in remaining capacity of the battery on a basis of state information of the battery which is received from the shutter glasses by the communication section.
