## Abstract

Provided a display device including a receiving unit that receives image data of a predetermined format for each frame; an additional information detection unit that detects an additional information disposed in a specific position of the image data of one frame received by the receiving unit; a synthesis unit that extracts division images of a still image disposed in the image data of one frame received by the receiving unit, synthesizes the extracted division images based on the additional information and assembles the still image greater than the number of pixels of the image data of one frame; and a display unit that displays the still image synthesized by the synthesis unit.

## Claims

### Claim 1

A display device comprising:
a receiving unit that receives image data of a predetermined format for each frame;
an additional information detection unit that detects additional information disposed in a specific position of the image data of one frame received by the receiving unit;
a synthesis unit that extracts division images of a still image disposed in the image data of one frame received by the receiving unit, synthesizes the extracted division images based on the additional information and assembles the still image greater than the number of pixels of the image data of one frame; and
a display unit that displays the still image synthesized by the synthesis unit.

### Claim 2 (depends on 1)

The display according to claim 1, wherein the image data received by the receiving unit is image data in which the same division images of the still image is repeatedly received in a plurality of frames, and
the additional information detected by the addition information detection unit includes information indicating the number of repetitive transmissions of the division images of the still image.

### Claim 3 (depends on 2)

The display according to claim 2, wherein the synthesis unit includes a memory that synthesizes the division images, and
writing the division images of one dividing area to the memory in the synthesis unit is completed within a period during which the same division images of the still images are repeatedly received in a plurality of frames.

### Claim 4 (depends on 1)

The display device according to claim 1, wherein the display unit does not display the image while the synthesis unit synthesizes the still image and the display unit displays the synthesized still image for each frame after the synthesis of the still image is completed in the synthesis unit

### Claim 5 (depends on 1)

The display device according to claim 1, further comprising:
a mode determination unit that determines a transmission mode of the received image data based on the additional information disposed in a specific position of the image data of one frame received by the receiving units, and
wherein when the transmission mode determined by the mode determination unit is a transmission mode transmitting the division images of the still image, the synthesis unit performs the synthesis of the still image and the display unit displays the synthesized still image.

### Claim 6 (depends on 5)

The display device according to claim 5, wherein the mode determination unit determines information of bits limited within information of a plurality of bits for indicating the transmission mode included in the additional information disposed in the specific position.

### Claim 7 (depends on 6)

The display device according to claim 6, wherein a bit position determined by the mode determination unit is set as a position varied for each frame.

### Claim 8 (depends on 6)

The display device according to claim 6, further comprising:
an image quality processing unit that performs an image quality processing of the image data received by the receiving unit, and
wherein when the transmission mode determined by the mode determination unit is a transmission mode transmitting the division images of the still image, the image quality process in the image quality processing unit is stopped.

### Claim 9

A display method comprising:
receiving image data of a predetermined format for each frame;
detecting an additional information disposed in a specific position of the image data of one frame received in the receiving of the image data;
extracting division image of a still image disposed in the image data of one frame received in the receiving of the image data, synthesizing the extracted division images based on the additional information and assembling the still image greater than the number of pixels of the image data of one frame; and
displaying the still image synthesized in the extracting of the division images.

### Claim 10

A transmitting device comprising:
a division processing unit that obtains data of a plurality of division images by dividing the image data of one still image for each predetermined area and disposing each of the obtained data of the plurality of division images in image data of a predetermined format having the number of pixels less than that of the still image;
an information addition unit that disposes additional information on division images in a specific position within the image data of the predetermined format obtained in the division processing unit; and
a transmitting unit that outputs whole produced frames while the additional information unit outputs repeatedly frames in which the additional information is disposed multiple times for each division image.

### Claim 11

A transmitting method comprising:
obtaining data of a plurality of division images by dividing the image data of one still image for each predetermined area and disposing each of the obtained data of the plurality of division images in image data of a predetermined format having the number of pixels less than that of the still image;
disposing additional information on division images in a specific position within the image data of the predetermined format obtained in the obtaining; and
outputting whole produced frames while repeatedly outputting frames in which the additional information is disposed multiple times for each division image in the disposing.
