Problems solved by technology

Hereinafter, referred to as an image source in a standby state) is skipped as in the case of an unusable image source, so there is a problem that the user cannot select such an image source in a standby state.
[0015] Moreover, these problems are not problems that only occur when searching for image sources in a projector, but are also seen when searching for image sources in an image display device that can connect multiple image sources

Embodiment approach 1

[0099] "Projector Composition"

[0100] figure 1 It is a block diagram showing a schematic configuration of a projector as an image display device of the present invention. Below, use figure 1 A schematic configuration of the projector 100 will be described.

[0101] The projector 100 separates white light emitted by a lamp 51 as a light source into three primary color components of red light, blue light, and green light, and uses liquid crystal light valves 52R and 52G for each color light of the display section for each color light. , 52B is modulated according to the image signal provided from the image source, and the recombined full-color modulated light is enlarged and projected onto the screen SC with the projection lens 65, so-called "liquid crystal 3-panel projector".

[0102] Among them, the liquid crystal light valves 52R, 52G, and 52B are light modulation elements, provided for red light, green light, and blue light, respectively, and included in the configura...

Embodiment approach 2

[0179] "Second Image Source Search Form"

[0180] Figure 11 ~ Figure 13 It is a figure which shows an example of the display screen in Embodiment 2. Figure 11 is the same as in Embodiment 1 image 3 corresponding figure, Figure 12 is the same as in Embodiment 1 Figure 7 corresponding figure, Figure 13 is the same as in Embodiment 1 Figure 9 corresponding figure.

[0181] The image source search support method according to Embodiment 2 is an image source search support method assuming that a search is performed for an image source different from the currently used image source while the projector is being used.

[0182] The configuration of the projector and the control program stored in the storage unit 66 are the same as those of the projector 100 according to the first embodiment.

[0183] Here, with figure 2 Centered, suitable for use figure 1 as well as Figure 11 ~ Figure 13 , and points different from those described in Embodiment 1 will be described. ...

Embodiment approach 3

[0195] "Search Form of the 3rd Image Source"

[0196] Figure 14 It is a flowchart showing the image source search support method according to the third embodiment. Figure 15 It is a figure which shows an example of the display screen in Embodiment 3.

[0197] The configuration of the projector is the same as that of the projector 100 according to the first embodiment.

[0198] Projector 100 according to Embodiment 3 is configured differently from Embodiment 1 only in the "image search program" stored in storage unit 66 .

[0199] Here, with Figure 14 as the center, suitably referring to Figure 13 , Figure 15 A mode of searching for an image source of the projector 100 will be described.

[0200] Since the “power button” of the remote controller 54 has been operated, an operation signal is sent from the operation accepting unit 55 to the control unit 66 . The control unit 66 having received the operation signal activates and initializes each unit. The control unit ...

Abstract

The invention provides a search support method for a video source by which, when the entire video sources are unusable, a user can recognize this state, and a video display device and a projector using the search support method. The search support method for video sources includes: a first step of receiving a video source search start operation by a user when a display based on one video source is performed, and displaying a search screen including a list of video sources that can be displayed in the display device; and a second step of performing a procedure of detecting the presence or absence of video signals in a predetermined order until a video signal is detected as to remaining video sources except for the above video source in the video sources that can be displayed in the display device. In the second step, when a video signal is detected, display based on the video source is started; and when a video signal is not detected even once, information of not detecting a video signal is displayed in a search screen.

Description

technical field [0001] The present invention relates to an image source search support method, an image display device and a projector using the search support method. Background technique [0002] Usually, a plurality of image sources (PC, DVD, VTR, other image devices, Internet, etc.) can be connected to a projector as an image display device. Figure 16 It is a diagram showing a state in which a plurality of image sources are connected to the conventional projector 500 . [0003] Projector 500, such as Figure 16 As shown, image light based on a desired image source is generated among the plurality of image sources PC1, PC2, VTR, and DVD, and is projected on the screen S. FIG. As an input and output interface, in addition to Figure 16 The input and output interfaces shown (I Computer1 , I Computer2 , I Video , IS-Video ), and recently LAN (wireless or wired) interfaces are also used. [0004] However, when using such a projector, in order to select a desired image s...
