Embodiment Construction

[0016] In the following, embodiments of the present invention will be described with reference to the drawings. In the embodiment, as the image output device, an image projection display device such as a projector is explained. The image projection display device modulates the light beam emitted from the light source to form an optical image according to an image signal input from an external device connected to it, such as a PC (Personal Computer), USB (Universal Serial Bus) memory, etc. The optical image formed is projected in an enlarged manner on the projection surface. It should be noted that the image projection display device according to the embodiment is configured such that its power state can be switched between a power-on state and a power-off state.

[0017] In the power-on (ON) state, the power is turned on, and operation instructions such as outputting image signals can be immediately executed. Further, the power-on state includes a standby state that can accept ...

Abstract

The invention discloses an image output device capable of switching between a normal state and a low-power state with lower power consumption than the normal state. The image output device includes: an interface for acquiring image signals; a signal detection a controller for detecting a signal at the interface; and a switching controller for switching the state from the low power state to the normal state based on the signal detection result in the low power state.

Description

Technical field [0001] The present invention relates to an image output device. Background technique [0002] Japanese Laid-Open Patent Publication No. 2008-89886 discloses an image projection display device such as a projector. In order to display information to people participating in meetings, lectures, presentations, etc., the image projection display device Image signals input from external devices such as computers), USB (Universal Serial Bus) memory, etc., project the image onto a projection surface such as a screen. [0003] When a user uses such an image projection display device, the user needs to connect an external device to the image projection display device and perform an operation for turning on the image projection display device. Therefore, when a user uses such an image projection display device, there is a problem that the user feels inconvenience because the user needs to separately perform the operation of connecting an external device to the image projection...
