Abstract

A display device and the like which can provide an image showing the status of the past presentation more flexibly is provided. A display device includes an image generating section generating an instruction image which reflects an instruction content based on presentation data obtained by relating image data showing a displayed image to display time data showing a display time of the displayed image and based on instruction information showing the instruction content, a display section displaying the instruction image, and an updating section updating the presentation data based on the instruction, and the image generating section generates a reproduction target time specifying image including a time region which changes as time passes and a specifying region which moves on the time region according to an instruction position and shows a reproduction target time, and the display section displays the reproduction target time specifying image.

Claims

1. A display device comprising:

an image generating section generating an instruction image which reflects an instruction content based on presentation data obtained by relating image data showing a displayed image to display time data showing a display time of the displayed image and based on instruction information showing the instruction content;

a display section displaying the instruction image; and

an updating section updating the presentation data based on information showing the instruction image,

wherein

the image generating section generates a reproduction target time specifying image including a time region which changes as time passes and a specifying region which moves on the time region according to an instruction position shown by the instruction information, the specifying region showing a reproduction target time of the image data, and

the display section displays the reproduction target time specifying image.

2. The display device according to claim 1, wherein

the image generating section generates an image including, as the time region in the reproduction target time specifying image, a first time region whose size changes according to a reproduction time of a presentation before update by the updating section and a second time region whose size changes according to the reproduction time of the presentation after update by the updating section.

3. The display device according to claim 2, wherein

the image generating section generates the reproduction target time specifying image showing the second time region in such a way as to branch off from a position of the first time region, the position indicating a time point at which update was performed.

4. The display device according to claim 1, wherein

the image generating section generates the displayed image from the reproduction target time, and

the display section displays the displayed image.

5. The display device according to claim 1, wherein

the instruction information is information showing an instruction content given by using an instruction tool.

6. The display device according to claim 5, wherein

the image data includes data showing a content of writing performed by the instruction tool in a display region of the instruction image,

the display time data includes data showing a time point at which the content of writing was written, and

the image generating section generates an image showing the content of writing as part of the displayed image from the reproduction target time.

7. A display method comprising allowing a display device to

generate an instruction image which reflects an instruction content based on presentation data obtained by relating image data showing a displayed image to display time data showing a display time of the displayed image and based on instruction information showing the instruction content,

display the instruction image,

update the presentation data based on information showing the instruction image,

generate a reproduction target time specifying image including a time region which changes as time passes and a specifying region which moves on the time region according to an instruction position shown by the instruction information, the specifying region showing a reproduction target time of the image data, and

display the reproduction target time specifying image.
