Abstract
A display system includes display terminals (1-1-1-4) that display pictures, a display control apparatus (3) that controls the display of pictures on the display terminals (1-1-1-4), and optical shutters (2-1-2-4) that are provided corresponding to each of the display terminals (1-1-1-4) and that enter a state of transmitting incident light in intervals in which private pictures are displayed on corresponding terminals and enter a state of blocking incident light in other intervals. The display control apparatus (3) controls the display terminals (1-1-1-4) such that private pictures are not simultaneously displayed on display terminals (1-1-1-4).
Claims34
A display system comprising:
- a plurality of terminals that display pictures within subframes of successive frames;
- a control apparatus that controls displaying said pictures, within said subframes of said successive frames, on each of said plurality of terminals;
- and
- a plurality of optical shutters provided respectively corresponding to each of said plurality of terminals, said shutters being placed in a state of transmitting incident light in subframe intervals in which said pictures are displayed on said terminals that correspond to said shutters and in a state of blocking incident light in other subframe intervals in which said pictures are not displayed on said corresponding terminals;
- wherein said plurality of terminals are arranged in proximity to each other, and
- wherein said control apparatus controls said plurality of terminals such that said pictures are non-simultaneously displayed on said plurality of terminals.
A control apparatus, comprising:
- a communication unit that carries out communication with each of a plurality of terminals that display pictures within subframes of successive frames according to display timing signals that are received as input, wherein a plurality of optical shutters are provided respectively corresponding to each of said plurality of terminals, said shutters being placed in a state of transmitting incident light in subframe intervals in which said pictures are displayed on said terminals that correspond to said shutters and in a state of blocking incident light in other subframe intervals in which said pictures are not displayed on said corresponding terminals, wherein said plurality of terminals are arranged in proximity to each other;
- and
- a display control unit that controls the display of said pictures, within said subframes of said successive frames, on each of said plurality of terminals;
- and
- wherein said display control unit determines for each of said plurality of terminals display timings of said pictures such that said pictures are non-simultaneously displayed on said plurality of terminals, and transmits through said communication unit to each of said plurality of terminals a signal that includes the display timing that was determined as said display timing signal.
A display method in a display system that includes a plurality of terminals that display pictures within subframes of successive frames, a control apparatus that carries out communication with said plurality of terminals, and a plurality of optical shutters provided respectively corresponding to each of said plurality of terminals and that carry out communication with corresponding terminals, said shutters being placed in a state of transmitting incident light in subframe intervals in which said pictures are displayed on said terminals that correspond to said shutters and in a state of blocking incident light in other subframe intervals in which said pictures are not displayed on said corresponding terminals, wherein said plurality of terminals are arranged in proximity to each other,;
- said display method comprising:
- determining, by said control apparatus, display timings of said pictures for each of said plurality of terminals such that said pictures are non-simultaneously displayed on each of said plurality of terminals, and transmitting, by said control apparatus, to each of said plurality of terminals a display timing signal that includes the display timing that was determined;
- displaying, by each of said plurality of terminals, said pictures, within said subframes of said successive frames, on each of plurality of terminals, in accordance with said display timing signal that was received from said control apparatus, and transmitting, by each of said plurality of terminals, to a corresponding optical shutter a synchronizing signal that indicates the display interval of the pictures;
- and
- carrying out, by each of said plurality of optical shutters, switching between a state of transmitting incident light during a period corresponding to displaying said pictures and a state of blocking incident light during another period corresponding to not displaying said pictures in accordance with said synchronizing signal that was received from the corresponding terminal.
A non-transitory computer readable medium storing a computer program incorporated in a control apparatus that is capable of communication with each of a plurality of terminals that display pictures within subframes of successive frames, in accordance with display timing signals that are received as input, wherein a plurality of optical shutters are provided respectively corresponding to each of said plurality of terminals, said shutters being placed in a state of transmitting incident light in subframe intervals in which said pictures are displayed on said terminals that correspond to said shutters and in a state of blocking incident light in other subframe intervals in which said pictures are not displayed on said corresponding terminals, wherein said plurality of terminals are arranged in proximity to each other, said program causing a computer of said control apparatus to execute processes of:
- determining the display timings of said pictures for each of said plurality of terminals such that said pictures, within said subframes of said successive frames, on each of said plurality of terminals, are non-simultaneously displayed on each of said plurality of terminals;
- and
- transmitting a signal that includes said display timings that were determined as said display timing signals to each of said plurality of terminals.
