Remote control device, method and system
According to a remote control device of the present invention, the operation situation according to the transmission of the remote control signal is judged based on a changing brightness of the image, and the information of the content according to the result of judgment is displayed. Thereby, it is possible to investigate a reaction of the apparatus to be controlled to the remote control signal, and visually indicate the reaction to the user.
1. A remote control device comprising:
an acquisition part that acquires continuously an image of an apparatus to be remotely controlled as a subject and an information inherent to the apparatus optically emitted from the apparatus using an image pickup element;
a display part that superimposes and displays the image acquired continuously by the acquisition part and the information inherent to the apparatus;
an instruction accepting part that accepts an instruction of selecting a desired apparatus subject to remote control among the apparatuses from which the inherent information is acquired and selecting a desired control content for the selected apparatus from a user;
a control signal transmission part that transmits a remote control signal to the apparatus;
a remote control part that controls the control signal transmission part to transmit a remote control signal corresponding to the control content of the apparatus selected by the instruction accepting part to the apparatus selected by the instruction accepting part; and
an operation situation judgment part that judges a presence or absence of the operation of the apparatus in accordance with the remote control signal depending on a changing brightness of the image acquired continuously by the acquisition part,
wherein the display part displays information of a content in accordance with a judgment of the operation situation judgment part.
2. The remote control device according to claim 1 , wherein the remote control part transmits the remote control signal again if the operation situation judgment part judges that the apparatus is not operated in accordance with the remote control signal.
3. The remote control device according to claim 2 , wherein the remote control part transmits the remote control signal only by a certain number of times if the operation situation judgment part judges that the apparatus is not operated in accordance with the remote control signal.
4. The remote control device according to claim 3 , wherein the display part displays prescribed information after the remote control part transmits the remote control signal only by the certain number of times if the operation situation judgment part judges that the apparatus is not operated in accordance with the remote control signal.
5. The remote control device according to claim 1 , wherein the operation situation judgment part judges whether or not the power of the apparatus is turned on in accordance with a remote control signal corresponding to the control content that the power of the apparatus is turned on, and the display part displays information concerning the controllable content after the power of the apparatus is turned on if the operation situation judgment part judges that the power of the apparatus is turned on.
6. The remote control device according to claim 2 , wherein the operation situation judgment part judges whether or not the power of the apparatus is turned on in accordance with a remote control signal corresponding to the control content that the power of the apparatus is turned on, and the display part displays information concerning the controllable content after the power of the apparatus is turned on if the operation situation judgment part judges that the power of the apparatus is turned on.
7. The remote control device according to claim 3 , wherein the operation situation judgment part judges whether or not the power of the apparatus is turned on in accordance with a remote control signal corresponding to the control content that the power of the apparatus is turned on, and the display part displays information concerning the controllable content after the power of the apparatus is turned on if the operation situation judgment part judges that the power of the apparatus is turned on.
8. The remote control device according to claim 4 , wherein the operation situation judgment part judges whether or not the power of the apparatus is turned on in accordance with a remote control signal corresponding to the control content that the power of the apparatus is turned on, and the display part displays information concerning the controllable content after the power of the apparatus is turned on if the operation situation judgment part judges that the power of the apparatus is turned on.
9. A remote control method comprising:
a step of acquiring continuously an image of an apparatus to be remotely controlled as a subject and an information inherent to the apparatus optically emitted from the apparatus using an image pickup element;
a step of superposing and displaying the image acquired continuously and the information inherent to the apparatus;
a step of accepting an instruction of selecting a desired apparatus subject to remote control among the apparatuses from which the inherent information is acquired and selecting a desired control content for the selected apparatus from a user;
a step of transmitting a remote control signal corresponding to the control content of the selected apparatus to the selected apparatus;
a step of judging the presence or absence of the operation of the apparatus in accordance with the remote control signal depending on a changing brightness of the image acquired continuously; and
a step of displaying information of the content in accordance with a judgment as to the presence or absence of the operation of the apparatus.
