no. 1 Embodiment approach

[0036] figure 1 It is a figure which shows the structure of the display system 1 of 1st Embodiment. The display system 1 includes a projector 11 (an example of a display device) and a PC (Personal Computer: personal computer) 21 (an example of an image providing device). The projector 11 and the PC 21 can be connected through the first communication and the second communication. In the first communication, the PC 21 displays an image G (refer to figure 2 ) image information GI (refer to Figure 4 ) to the projector 11, and in this second communication, information other than the image information GI is transmitted and received between the PC 21 and the projector 11. The first communication is via, for example, a communication cable such as an RGB (Red Green Blue) cable, a DVI (Digital Visual Interface: Digital Visual Interface) cable, or an HDMI (registered trademark) (High-Definition Multimedia Interface: High-Definition Multimedia Interface) cable. 61 to proceed. The se...

no. 2 Embodiment approach

[0119] In the first embodiment, the determination unit 236 determines whether or not the PC interaction process is being executed based on whether or not a specific application is being activated. On the other hand, in the second embodiment, the storage unit 22 stores information for specifying an application having a program capable of realizing the PJ interaction processing execution unit 142, and the determination unit 236 refers to the storage content of the storage unit 22 to determine the PC interaction Whether processing is in progress. Furthermore, in the second embodiment, when receiving an instruction to cut off the USB communication, the control unit 237 instructs the projector 11 to execute the PJ interactive process. Hereinafter, the second embodiment will be described. In addition, in each form and each modification example illustrated below, the code|symbol used in 1st Embodiment is attached|subjected to the element whose operation|movement or function is the s...

Abstract

An image providing device, a method for controlling the image providing device, and a recording medium are provided. When the display device and the image providing device can execute a predeterminedprocess corresponding to a position of an indicator on a display surface, the possibility that both the display device and the image providing device do not execute the predetermined process can be reduced. The image providing device provides image information to the display device capable of executing the predetermined process and a first process, and a second process and the predetermined process can be executed; the first process displays a first image for executing the predetermined process on the display surface, the second process provides information indicating a second image for executing the predetermined process to the display device, and the image providing device includes: a receiving unit that receives, from the display device, a notification representing that the display device is executing the first process; a determination unit that determines whether or not the image providing device is executing the second process; and a control unit that causes the display device tostop the first process when the receiving unit receives the notification and the determination unit determines that the image providing device is executing the second process.

Description

technical field [0001] The present invention relates to an image providing device, a method of controlling the image providing device, and a recording medium. Background technique [0002] Various display devices have been proposed that perform processing corresponding to the position of a pointer on a display surface (hereinafter, also referred to as “predetermined processing”). In predetermined processing, for example, a line is drawn on the display surface according to the position of the pointer. The display device displays an operation image for executing predetermined processing on the display surface. The operation image is, for example, at least any one of a pointer image showing the position of the tip of the pointer as the position of the pointer, and a menu bar image for assisting execution of predetermined processing. The menu bar image includes, for example, buttons for executing predetermined processing. Patent Document 1 discloses a display device capable o...
