Abstract

An image display control device according to the present invention includes a display control unit, an obtaining unit, a drawing unit, a deleting unit, and an operating unit. The display control unit displays an image on a display device. The obtaining unit obtains contact position information or proximity position information of a drawing device, which is relative to a display area of the display device. The drawing unit generates a drawn image, compose a display image of an information processing apparatus with the drawn image, and displays the composite image on the display device. The deleting unit deletes the drawn image from the displayed image, and display on the display device. The operating unit operates the information processing apparatus. The drawing device switches and specifies a generation and deletion of the drawn image, and an operation of the information processing apparatus.

Dependent claims

A display device, comprising:

a first interface configured to receive a video signal of a display image of an information processing apparatus that is external to the display device;
a second interface configured to send, to the information processing apparatus, control signals based on a coordinate position of a drawing device;
and
processing circuitry configured to
cause display of the display image based on the received video signal, the display image being displayed in a first display area of a display surface;
cause display of user interface elements in a second display area of the display surface different from the first display area;
acquire a contact signal based on a contact position of the drawing device;
determine whether the contact position of the drawing device is in one of the first display area and the second display area;
transmit a first control signal to the information processing apparatus via the second interface when the contact position of the drawing device is determined to be in the first display area;
and
transmit a second control signal different from the first control signal to the display device when the contact position of the drawing device is determined to be in the second display area.

A display method, comprising:

receiving, via a first interface of a display device, a video signal of a display image of an information processing apparatus that is external to the display device;
transmitting, via a second interface of the display device, control signals to the information processing apparatus, the control signals based on a coordinate position of a drawing device;
causing display of the display image based on the received video signal, the display image being displayed in a first display area of a display surface;
causing display of user interface elements in a second display area of the display surface different from the first display area;
acquiring a contact signal based on a contact position of the drawing device;
and
determining whether the contact position of the drawing device is in one of the first display area and the second display area, wherein
the transmitting includes:
transmitting a first control signal to the information processing apparatus via the second interface when the contact position of the drawing device is determined to be in the first display area;
and
transmitting a second control signal different from the first control signal to the display device when the contact position of the drawing device is determined to be in the second display area.
