Problems solved by technology

That is to say, when calling out the registered parameter set, there is a problem that it is difficult to determine a desired parameter set from a plurality of parameter sets.
Similarly, when registering a parameter set, it is difficult to confirm the contents of the registered parameter set. Therefore, although there is a limit on the number of parameter sets that can be registered due to memory capacity constraints, etc., there is still a possibility of registering too many. questions with the same or similar set of parameters

Embodiment approach 1

[0047] Hereinafter, an image display device according to Embodiment 1 of the present invention will be described with reference to the drawings.

[0048] figure 1 It is a block diagram showing a schematic configuration of a projector as an image display device according to this embodiment.

[0049] The projector 1 modulates light emitted from a light source based on an externally input image signal to form an optical image, and enlarges and projects the formed optical image onto a screen SC.

[0050] Such as figure 1 As shown, the projector 1 includes a projection unit 10 for projecting an image. The projection unit 10 includes: a light source 11 composed of a discharge-type light source lamp such as an ultra-high pressure mercury lamp or a metal halide lamp; a liquid crystal light valve 12 as a light modulation device; a projection lens 13; and a light valve drive unit 14 .

[0051] In the liquid crystal light valve 12, a plurality of pixels are formed, and the liquid crys...

Embodiment approach 2

[0088] Hereinafter, an image display device according to Embodiment 2 of the present invention will be described with reference to the drawings.

[0089] The control unit 20 of the projector 1 as the image display device according to the present embodiment, when registering the parameter set in the storage unit 21, sets the information indicating the input terminal selected by the input source switching unit 24 at that time (input terminal information ) is stored as one of the parameters corresponding to the identifier. In addition, when the registered parameter set is called, the name of the corresponding input terminal is displayed together with the identifier on the menu image for selecting a desired parameter set.

[0090] Figure 9 It is an explanatory diagram showing an OSD image displayed when a parameter set is called in the projector 1 according to the present embodiment.

[0091] When the memory operation menu image Gm4 is displayed (refer to Figure 6 ) state, wh...

Embodiment approach 3

[0101] Hereinafter, an image display device according to Embodiment 3 of the present invention will be described with reference to the drawings.

[0102] The projector 1 as the image display device according to this embodiment can set parameters currently in use in the menu image Gm5 for memory registration and the menu image Gm6 for memory recall when performing memory registration and memory recall. The parameters in are compared with the parameters included in the parameter group registered in the storage unit 21.

[0103] Figure 11 It is an explanatory diagram showing an OSD image displayed when a parameter set is registered in the projector of the present invention.

[0104] When the memory operation menu image Gm4 is displayed (refer to Figure 6 ) state, when "memory registration" is selected, the control unit 20 instructs the OSD processing unit 27 to superimpose and display an OSD image (menu image for memory registration) for registering a parameter set on the inp...

Abstract

The present invention provides an image display device and a projector capable of improving the convenience of selecting a desired parameter set from a plurality of parameter sets when calling a parameter set. In addition, the present invention provides an image display device and a projector capable of easily confirming setting contents of a registered parameter set when registering a parameter set. In the image display device of the present invention, in the memory call menu image Gm6 displayed when a desired set is called out of a plurality of sets of parameter sets stored in the storage unit, parameters indicating the color mode are listed in the vertical direction, and Nine identifiers ("memory 1" to "memory 9") for identifying parameter groups are displayed on the right side of the parameters corresponding to each. That is, nine identifiers are classified into color mode categories.

Description

technical field [0001] The present invention relates to an image display device and a projector capable of adjusting the display state of an image to be displayed. Background technique [0002] Many image display devices that display images based on image signals allow users to adjust image quality by setting parameters indicating brightness, contrast, and hue of the image. The user can appropriately set these parameters according to the category of the image (still image, moving image), its content (movie, sports, news, etc.), or the audio-visual environment such as the brightness of the room. However, since parameter setting work is required every time the image, audio-visual environment, etc. change, the more parameters to be set, the more complicated the work will be. [0003] In order to reduce the complexity of the above-mentioned work, such an image display device (projector) has been proposed, which can store (register) the combination (parameter group) of various p...
