Problems solved by technology

[0004] However, if an operation figure such as a menu screen is displayed, operations such as drawing and the like cannot be performed at the display position, so if the operation figure is displayed unnecessarily, operability may be impaired.
On the other hand, if the graphics for operation are not displayed when the display is required, it will also become an important factor that destroys operability.

Embodiment Construction

[0029] Hereinafter, embodiments to which the present invention is applied will be described with reference to the drawings.

[0030] figure 1 It is a figure which shows the structure of the display system 10 which concerns on an embodiment.

[0031]The display system 10 (image display system) is configured to include a projector 11 that projects an image onto a screen SC, and a PC (Personal Computer) 13 that transmits the image to the projector 11 . Projector 11 and PC 13 are mutually communicably connected via communication network 12 , and multiple PCs 13 are connected to communication network 12 . Each PC 13 can execute the projector control program 13A for controlling the projector 11 and can control the projector 11 independently, but only one PC 13 can control the projector 11 at the same time. Therefore, each PC 13 can start controlling the projector 11 in a state where other PCs 13 are not controlling the projector 11 .

[0032] The communication network 12 is, for ...

Abstract

An image supply device used with an image display device and an operation detection device adapted to detect an indication location in accordance with a position indication operation on a display surface includes a drawing section adapted to generate a superimposition image to be displayed while being superimposed on an original image based on the indication location detected by the operation detection device, a first image generation section adapted to generate a first composite image by superimposing the superimposition image generated by the drawing section on the original image, a second image generation section for generating a second composite image by superimposing an operating image for instructing a process of the superimposition image generated by the drawing section on the first composite image in response to a change in the original image, and an output section adapted to output the second composite image to the image display device.

Description

technical field [0001] The present invention relates to an image supply device that outputs an image to an image display device, an image display system, a control method for the image supply device, an image display device, and a recording medium. Background technique [0002] Conventionally, a system is known that enables handwriting input by manipulating a display surface with a coordinate input device such as a touch pen (for example, refer to Patent Document 1). The system described in Patent Document 1 employs a GUI (Graphical User Interface) using, for example, operational graphics such as a menu screen when drawing or instructing information processing using a coordinate input device. In the system of Patent Document 1, a menu screen serving as an operation graphic is arranged on a display screen, and information input by handwriting can be processed by operating the menu screen. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2009-157448 [0004] However...
