Abstract

In order to display selected content as desired by a viewer by performing an easy operation without interrupting current viewing, a display apparatus includes a reception unit for receiving from a remote controller for transmitting an operation instruction to the display apparatus operation information including the amount of operation of a selection member which is detected at the time of selecting content and identification information identifying selected content, a determination unit for determining an output attribute of the selected content identified using the identification information based on the amount of operation, an output image generation unit for generating an output image of the selected content based on the output attribute determined by the determination unit, and a display control unit for displaying the output image generated by the output image generation unit.

Claims

1. A display apparatus comprising:

a reception unit configured to receive from a remote controller for transmitting an operation instruction to the display apparatus operation information including the amount of operation of a selection member which is detected at the time of selecting content and identification information identifying selected content;

a determination unit configured to determine an output attribute of the selected content identified using the identification information based on the amount of operation, the identification information and the amount of operation being included in the operation information received by the reception unit;

an output image generation unit configured to generate an output image of the selected content based on the output attribute determined by the determination unit; and

a display control unit configured to display the output image generated by the output image generation unit.

2. The display apparatus according to claim 1,

wherein the determination unit determines a transparency of the selected content identified using the identification information as the output attribute based on the amount of operation, the identification information and the amount of operation being included in the operation information received by the reception unit, and

wherein the output image generation unit generates the output image of the selected content based on the transparency determined by the determination unit.

3. The display apparatus according to claim 1,

wherein the determination unit determines a display size of the selected content identified using the identification information as the output attribute based on the amount of operation, the identification information and the amount of operation being included in the operation information received by the reception unit, and

wherein the output image generation unit generates the output image of the selected content based on the display size determined by the determination unit.

4. The display apparatus according to claim 1,

wherein the determination unit determines a display position of the selected content identified using the identification information as the output attribute based on the amount of operation, the identification information and the amount of operation being included in the operation information received by the reception unit, and

wherein the output image generation unit generates the output image of the selected content based on the display position determined by the determination unit.

5. The display apparatus according to claim 1 further comprising:

an output sound generation unit configured to generate output sound of the selected content based on output attribute determined by the determination unit; and

a sound output unit configured to output the output sound generated by the output sound generation unit.

6. The display apparatus according to claim 1, wherein the amount of operation is the amount of pressure applied to the selection member, the number of pressing stages of the selection member, or a pressing duration of the selection member.

7. The display apparatus according to claim 1, wherein the display control unit performs display control processing so as to superimpose the output image generated by the output image generation unit on a display screen of content being viewed.

8. A remote controller for transmitting an operation instruction to a display apparatus, comprising:

a content selection unit configured to select a piece of content from among pieces of content displayed by the display apparatus in accordance with a user'"'"'s operation of a selection member;

an operation amount detection unit configured to detect the amount of operation of the selection member; and

a transmission unit configured to transmit to the display apparatus operation information including the amount of operation detected by the operation amount detection unit and identification information identifying content selected by the content selection unit.

9. A display control method of a display apparatus comprising:

receiving from a remote controller for transmitting an operation instruction to the display apparatus operation information including the amount of operation of a selection member which is detected at the time of selecting content and identification information identifying selected content;

determining an output attribute of the selected content identified using the identification information based on the amount of operation, the identification information and the amount of operation being included in the operation information received in the receiving step;

generating an output image of the selected content based on the output attribute determined in the determining step; and
