The image processing device includes a detecting section, an acquiring section, and a generating section. The detecting section detects a difference between a first screen and a second screen. The acquiring section acquires a snapshot of the first screen and a snapshot of the second screen. The detecting section calculates an amount of change between the first screen and the second screen. When the amount of change between the first screen and the second screen is equal to or greater than a threshold, the generating section generates a document of the snapshot of the first screen acquired by the acquiring section. ## Claims ### Claim 1 An image processing device for processing screen data displayed on a display device in a remote conference, comprising: a detecting section configured to compare a first screen displayed on the display device and a second screen displayed on the display device after the first screen, and detect a difference between the first screen and the second screen; an acquiring section configured to acquire a snapshot of a screen displayed on the display device; and a generating section configured to generate a document of the snapshot, wherein the acquiring section acquires a snapshot of the first screen and a snapshot of the second screen, the detecting section calculates an amount of change between the first screen and the second screen based on the difference between the first screen and the second screen, and when a result of calculation by the detecting section is equal to or greater than a threshold, the generating section generates a document of the snapshot of the first screen acquired by the acquiring section, and wherein the acquiring section acquires a snapshot of a specific area within the first screen displayed on the display device and a snapshot of a specific area within the second screen displayed on the display device, the specific area within the first screen and the specific area within the second screen are located at the same location. ### Claim 2 An image processing device for processing screen data displayed on a display device in a remote conference, comprising: a detecting section configured to compare a first screen displayed on the display device and a second screen displayed on the display device after the first screen, and detect a difference between the first screen and the second screen; an acquiring section configured to acquire a snapshot of a screen displayed on the display device; and a generating section configured to generate a document of the snapshot, wherein the acquiring section acquires a snapshot of the first screen and a snapshot of the second screen, the detecting section calculates an amount of change between the first screen and the second screen based on the difference between the first screen and the second screen, and when a result of calculation by the detecting section is equal to or greater than a threshold, the generating section generates a document of the snapshot of the first screen acquired by the acquiring section, and wherein the detecting section calculates an amount of change between a specific area within the first screen displayed on the display device and a specific area within the second screen displayed on the display device, the specific area within the first screen and the specific area within the second screen are located at the same location, and when the result of the calculation by the detecting section is equal to or greater than the threshold, the generating section generates a document of the snapshot of the specific area within the first screen.
