Abstract
A projector includes: a data input section which input the data of an image and/or sound; a data output section which outputs the input data; and a data transfer section which captures the data before being output by the data output section, and transfers the captured data to one or more other projectors, wherein the data output section transfers the data by the data transfer section and then outputs the data input from the data input section.
Claims17
A projector comprising:
- a data input section which input the data of an image and/or sound;
- a data output section which outputs the input data;
- and
- a data transfer section which captures the data before being output by the data output section, and transfers the captured data to one or more other projectors,
- wherein the data output section transfers the data by the data transfer section and then outputs the data input from the data input section.
A projector system comprising a first projector and one or more second projectors which are connected to the first projector,
- the first projector including:
- a data input section which input the data of an image and/or sound;
- a first data output section which outputs the input data;
- and
- a data transfer section which captures the data before being output by the first data output section, and transfers the data to the one or more second projectors,
- the one or more second projectors each including:
- a data receiving section which receives the data transferred from the first projector;
- and
- a second data output section which outputs the data after receiving the data,
- wherein the first data output section transfers the data by the data transfer section and then outputs the data input from the data input section.
A data output method of a projector which can be connected with one or more other projectors, comprising:
- inputting data of an image and/or sound;
- outputting the input data;
- capturing the data before being output in the outputting of the data, and transferring the captured data to the one or more other projectors;
- temporarily storing the input data in a temporary storage section;
- transmitting a synchronization signal for calculating a time taken for the data transmission to the one or more other projectors, and receiving a response signal for the synchronization signal from the one or more other projectors to which the synchronization signal is transmitted;
- obtaining a transmission and reception time from the transmission of the synchronization signal to the reception of the response signal to the one or more other projectors;
- and
- calculating a synchronization adjustment time for synchronizing the data output from the one or more other projectors on the basis of the obtained transmission and reception time,
- wherein the data stored in the temporary storage section is delayed by the maximum time out of all the synchronization adjustment times calculated in the calculating of a synchronization adjustment time, to be output, in the outputting of the input data, and
- when a time obtained by subtracting the synchronization adjustment time of the other projectors which are transfer destinations from the maximum time elapses, at the time of the transfer of the data to the one or more other projectors, the data is transferred to the other projector which are the transfer destinations in the capturing and transferring of the data.
A data output method of a projector system using a first projector and one or more second projectors which are connected with the first projector, comprising:
- in the first projector,
- inputting data of an image and/or sound;
- outputting the input data
- capturing the data before being output in the outputting of the data, and transferring the captured data to the one or more second projectors, and
- in each of the one or more second projectors,
- receiving the data transferred from the first projector;
- and
- outputting the data after the receiving of the data,
- wherein in the outputting of the input data in the first projector, the data input in the inputting of data is output after the data is transferred in the capturing and transferring of the data.
