Problems solved by technology

[0008] Therefore, when the observer adopts a posture with a tilted face, the left and right eyes are tilted relative to the horizontal direction, so the displayed image cannot be stereoscopically observed through the shutter glasses.
In other words, there is a problem of giving the observer a sense of discomfort (discomfort) in the above postures.

no. 1 Embodiment

[0055] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

[0056] 〔Configuration of the image display system〕

[0057] figure 1 It is a perspective view of an example of use of the image display system 1 .

[0058] The image display system 1 enables the observer to observe and display the image stereoscopically, such as figure 1 As shown, a display device 2 and shutter glasses 3 are provided as an image display device.

[0059] 〔Configuration of the display device〕

[0060] figure 2 is a block diagram of the configuration of the display device 2 .

[0061] The display device 2 is on the screen P ( figure 1 ) to display the image.

[0062] The display device 2 such as figure 2 As shown, it includes an input interface unit 21, a signal processing unit 22 as a control unit, a display unit 23, and a light emitting unit 24 as a signal output unit.

[0063] The signal processing unit 22 receives an input signal ( ...

no. 2 Embodiment

[0136] Next, a second embodiment of the present invention will be described with reference to the drawings.

[0137] In the following description, the same configuration and the same components as those of the above-mentioned first embodiment are given the same symbols, and the detailed description thereof will be omitted or simplified.

[0138] Image 6 It is a block diagram of the configuration of the shutter glasses 3 in the second embodiment.

[0139] In this embodiment, with respect to the above-mentioned first embodiment, as Image 6 As shown, only the configuration of the shutter glasses 3 is different.

[0140] Specifically, the shutter glasses 3 in the second embodiment are as compared to the above-mentioned first embodiment, as Image 6 As shown, the signal selection unit 38 and the second signal conversion unit 374 are added as the timing selection unit.

[0141] In addition, other configurations are the same as those of the above-mentioned first embodiment.

...

no. 3 Embodiment

[0161] Next, a third embodiment of the present invention will be described with reference to the drawings.

[0162] In the following description, the same configuration and the same components as those of the above-mentioned second embodiment are given the same symbols, and the detailed description thereof will be omitted or simplified.

[0163] Figure 8 It is a block diagram of the configuration of the shutter glasses 3 in the third embodiment.

[0164] In this embodiment, with respect to the above-mentioned second embodiment, as Figure 8 As shown, only the configuration of the shutter glasses 3 is different.

[0165] Specifically, the shutter glasses 3 in the third embodiment are as compared with the above-mentioned second embodiment, as Figure 8 As shown, the only difference is that the signal selection unit 38 is omitted, and the second signal conversion unit 374 is operated based on the output signal S2 from the tilt state determination unit 36 ​​. Other configurat...

Abstract

Shutter glasses include a left-eye selection part and a right-eye selection part that respectively switch to a transmission state or a blocking state, a tilt detection part that detects a tilt condition of the shutter glasses, a tilt condition determination part that compares an output value of the tilt detection part and a predetermined threshold value, a signal acquisition part that acquires a left switch signal in synchronization with the image for left eye and a right switch signal in synchronization with the image for right eye, and a switching operation part that switches the left-eye selection part and the right-eye selection part to the transmission state or the blocking state. When the output value is equal to or more than the threshold value, the switching operation part switches both the left-eye and the right-eye selection parts in response to one of the left and the right switch signal.

Description

technical field [0001] The invention relates to shutter glasses and an image display system. Background technique [0002] Conventionally, there is known an image display system (stereoscopic image display device) that is equipped with an image display device for displaying an image and shutter glasses worn by an observer, and stereoscopically observes a display image displayed on the image display device through the shutter glasses (for example, refer to Patent No. Literature 1). [0003] In the image display system described in Patent Document 1, the image display device displays an image for the left eye during a first display period, displays an image for the right eye during a second display period, and alternately displays the image for the left eye and the image for the right eye in time-division every display period. Eye image. [0004] In addition, the shutter glasses are composed of so-called liquid crystal shutters, and in synchronization with the above-mentione...
