no. 1 Embodiment approach

[0024] Such as figure 1 As shown, the projector 20 of the first embodiment is a display device that displays the image D by projecting light representing the image D on the screen C. As shown in FIG. The projector 20 is supplied with a video signal representing the image D, for example, from an external device (not shown) having a function of outputting a video signal. The projector 20 may be supplied with a video signal from another medium, or may generate a video signal in the projector 20 .

[0025] Such as figure 2 As shown, the projector 20 has an input device 21 , an interface (I / F) 22 , a power supply circuit 23 , a control circuit 24 , an image generation circuit 27 , and a projection device 30 . The input device 21 accepts user operations, and outputs signals corresponding to the user operations to the control circuit 24 . As the input device 21 , various input devices such as keys, touch sensors, switches such as keyboards, mice, touch panels, digitizers, and poi...

no. 2 Embodiment approach

[0050] Such as Figure 5 As shown, the projector 20A of the second embodiment differs from the first embodiment in that it includes a notification unit 45 that notifies the user of a job that has been set to stop processing, and the like. The configuration, processing, operation, and effects not described in the second embodiment are the same as those in the first embodiment, and thus are omitted.

[0051] The projector 20A has a shutter 41 that opens and closes a window 40 of the casing, and a push button 42 that slides on a rail 43 in conjunction with the shutter 41 . The window 40 exposes the projection lens 33 disposed inside the casing of the projector 20A to the outside. The projection lens 33 is one of the optical systems of the projection device 30 . The projection lens 33 projects the light modulated by the display element 32 as an image D to the outside of the casing. The shutter 41 opens and closes the window 40 by operating integrally with the push button 42 ope...

Abstract

Provided are a projector control method and a projector. A user does not need to wait for a normal state in order to perform a stop operation. A projector control method for controlling a projector having an input device that accepts a start operation instructing start and a stop operation instructing stop by a control circuit, the projector control method including the steps of: after start processing is started in response to the start operation, controlling the input device to receive the start operation instructing start and the stop operation instructing stop by the control circuit; shifting to a preparation state of preparing a normal state; responding to a stop operation in the preparation state, and setting a task of stopping processing; and in response to the end of the preparation state, executing the task.

Description

technical field [0001] The present invention relates to a control method of a projector and the projector. Background technique [0002] Patent Document 1 discloses a projector which, after a power switch is turned on, displays on a display unit how long it will take to complete warm-up based on the progress of warm-up of a light source lamp. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2005-17583 [0004] Generally, the projector cannot be turned off even if the power switch is operated in the standby state preceding the normal state. Therefore, in order to turn off the power, the user needs to wait for the end of the ready state. Contents of the invention [0005] The first aspect is a method for controlling a projector that controls a projector having an input device that accepts a start operation for instructing start and a stop operation for instructing stop through a control circuit. The control method includes the steps of: shifting to a standby stat...
