Abstract: A display apparatus includes a first detection section detects the position of a first indicator on the image. A second detection section detects the position of a second indicator on the image. A storage section includes a first storage region corresponding to the first indicator and a second storage region corresponding to the second indicator. The first storage control section stores a first virtual object relating to the first indicator in the first storage region. The second storage control section stores a second virtual object relating to the second indicator in the second storage region. A first pasting section pastes the first virtual object stored in the first storage region to the image according to an operation of the first indicator. A second pasting section pastes the second virtual object stored in the second storage region to the image according to an operation of the second indicator.

Abstract: A client can return a display state of an object to the past. When a point body moves on a screen, a projector draws an object of a line representing a moving trajectory. The projector generates object data representing the object and transmits the generated object data to tablet terminals. The object data contains order information representing generation order of the object. The tablet terminals display the object represented by the transmitted object data on a touch panel. When performing an operation for returning the display, the tablet terminals return the display by object unit based on the order information contained in the object data.

Abstract: A projector includes a coordinate acquiring unit configured to acquire a coordinate of a position pointed by a pointer, a sub-processor configured to render an image on the basis of the coordinate, and a main processor configured to output image data of the image rendered by the sub-processor. The projector performs, according to a predetermined condition, using the main processor, rendering in the same manner as the sub-processor on the basis of the acquired input coordinate, superimposes the rendered image on the rendered image output by the sub-processor to generate a superimposed image, and outputs the superimposed image.
