Description

  Embodiments described herein relate generally to a mask using a function for adjusting luminance and contrast for stereoscopic glasses.

  Television apparatuses using a liquid crystal panel are rapidly spreading. With regard to such a television device, in recent years, a system capable of producing right and left parallax by combining special glasses and a corresponding television device to enable three-dimensional stereoscopic viewing has begun to spread.

  In such a stereoscopic television system, the most representative technique is to display dedicated video frames alternately on the left and right eyes, and to block the field of view with dedicated glasses equipped with a high-speed switchable liquid crystal shutter. Is used, and a method for projecting separate images to the left and right is used.

However, the video brightness is lowered by switching the left and right liquid crystal shutters at high speed. In conventional television devices, the screen brightness is often improved by setting the brightness of the video to be displayed high, but this method still has problems such as a decrease in dynamic range and an increase in power consumption (for example, patents). See reference 1.)

  On the other hand, there is a demand for improving the sensation luminance, but no means for realizing such demand is known.

FIG. 8 is a diagram showing an example of an overview of the stereoscopic video display system 81 in the present embodiment. FIG. 8 shows a stereoscopic video display system 81, a video display device 82, and shutter glasses 83.

  The stereoscopic video display system 81 includes a video display device 82 and shutter glasses 83. The user can recognize the video as a stereoscopic video by wearing the shutter glasses 83 and viewing the video displayed on the video display device 82.

  Humans usually view an object with the left eye and the right eye, which are located at different positions, and there are parallaxes in the images seen with the left eye and the right eye. By synthesizing the image seen with the left eye and the image seen with the right eye in the brain where the parallax exists, a human can recognize the object being viewed as a solid. Therefore, by displaying the left-eye image and the right-eye image having parallax with each eye, it is possible to make the user perceive the video as a three-dimensional image.

  The video display device 82 is, for example, a digital television, and can display a stereoscopic video to a user wearing the shutter glasses 83 by alternately displaying a left-eye image and a right-eye image having parallax with each other. The video display device 82 also has a function of generating a new image based on the received image signal for stereoscopic video display.

  The shutter glasses 83 have a left-eye lens 84 and a right-eye lens 85. The left-eye lens 84 and the right-eye lens 85 are each provided with a light-shieldable shutter, and the user opens and closes the shutter at different timings based on the shutter opening / closing signals received from the video display device 82. 3D images are provided. For example, when a left-eye image is displayed on the video display device 82, the shutter glasses 83 closes the shutter of the right-eye lens 85 and opens the left-eye lens 84 based on an open / close signal from the video display device 82. The left eye image is shown only to the user's left eye. When the right-eye image is displayed, the shutter of the left-eye lens 84 is closed and the right-eye lens 85 is opened, so that the right-eye image is shown only to the user's right eye. By doing so, the user can grasp the image being viewed as a solid. In more detail, the shutter glasses 83 are accompanied by a mask 83a described later.

(Example)
FIG. 1 is a block diagram showing an example of the internal functional configuration of the stereoscopic video display system 81 in the present embodiment.
As shown in FIG. 1, a stereoscopic TV / video display device 12 includes a tuner 11, a cord holding unit 5, a display control unit 2, an L / R open / close signal light emitting unit 4 (corresponding to the infrared transmission unit 24), and a display unit. 3 (corresponding to the display 20), for example, can receive a transmitted broadcast signal and provide a stereoscopic video to the user.

The tuner 11 has a function as input means for decoding the broadcast signal received by the antenna and inputting the decoded signal into the video display device 82.
The display control unit 2 has a function of causing the display unit 3 to display image data obtained by demodulating and digitizing the decoded signal. At this time, the display control unit 2 controls the display time of each image in the image data. It is preferable that the time for displaying one image is a half of the cycle in which the left eye image and the right eye image are taken. For example, if the left-eye imaging and the right-eye imaging are each continuously captured at a 1/60 second period, the video display device 12 switches the displayed image every 1/120 second. Further, the display control unit 2 transmits a signal related to the opening / closing of the shutter glasses 83 to the L / R opening / closing signal light emitting unit 4 as the light emission timing so that the shutter glasses 83 open / close the shutter in synchronization with the switching of the images. .

  When the L / R opening / closing signal light emitting unit 4 receives the signal related to opening / closing of the shutter glasses 83 from the display control unit 2, the L / R opening / closing signal light emitting unit 4 outputs an opening / closing signal for instructing the shutter glasses 83 to open / close the shutter by infrared rays (code holding unit 5). It has a function as a signal transmission means for transmitting a code held in the. In the present embodiment, it is exemplified that the open / close signal is transmitted by infrared rays. However, the present invention is not limited to this, and other wireless transmission methods may be used as long as the open / close signal can be transmitted. Further, the video display device 82 and the shutter glasses 83 may be connected by a wired cable capable of transmitting and receiving signals.

  As shown in FIG. 1, the shutter glasses 83 have the following configuration. The light receiving unit 6 receives an infrared light emission signal from the TV side and converts it into an electrical signal. The decoding unit 7 compares the code data of the code holding unit 8 with the electrical signal from the light receiving unit 6 and generates a coincidence signal. The shutter control unit 9 controls the opening / closing of the left / right shutter of the glasses based on the timing of the coincidence signal from the decoding unit 7.

The shutter glasses 83 open and close the shutter based on the open / close signal received from the L / R open / close signal light emitting unit 4.
The switching of the display displayed on the display unit 3 and the shutter opening / closing cycle of the left and right lenses of the shutter glasses 83 will be described below.
As a conventional example of a stereoscopic television system using shutter glasses, there is a portion that overlaps with the above description, but there is a method in which infrared light or the like is transmitted from the TV side and the shutter opening / closing timing of the glasses is controlled. FIG. 4 is a diagram schematically showing opening and closing of the shutter of the shutter glasses. For example, in the case of a TV that displays at 120 fps, the image for the left eye and the image for the right eye are displayed alternately every approximately 8.3 mS, and the sync pulse is infrared at the start of the image display for the left eye every Tfrm (16.6 mS = 8.3 + 8.3). Use to send to shutter glasses. The shutter glasses generate a Lopen / Ropen signal from this synchronization pulse. When the Lopen signal is “1”, the right-eye shutter is opened and closed with “0”. When the Ropen signal is “1”, the left-eye shutter is opened and closed with “0”. In this way, stereoscopic display is realized by matching the right / left eye image display on the tv side and the shutter opening / closing timing of the shutter glasses.

FIG. 2 is a block diagram showing another example (mask 83a) of the internal functional configuration of the stereoscopic video display system 81 in the present embodiment. Description of parts common to FIG. 1 is omitted.
As shown in FIG. 2, the stereoscopic TV / video display device 12 includes a tuner 11, a cord holding unit 5 a, a display control unit 2, a mask signal light emitting unit 4 a (corresponding to the infrared transmission unit 24), and a display unit 3 (display). 20).

The tuner 11 has a function as input means for decoding the broadcast signal received by the antenna and inputting the decoded signal into the video display device 82.
The display control unit 2 has a function of causing the display unit 3 to display image data obtained by demodulating and digitizing the decoded signal. At this time, the display control unit 2 controls the display time of each image in the image data.

The display control unit 2 transmits mask information to the mask signal light emitting unit 4a as a signal for the mask 83a at a light emission timing of a signal related to opening / closing of the shutter glasses 83a synchronized with the switching of the image.

  When the mask signal light emitting unit 4a receives the mask information signal from the display control unit 2, the mask signal light emitting unit 4a transmits a signal (a code held in the code holding unit 5a) to instruct the mask 83a with an infrared ray. It has a function as a means. In this embodiment, it is exemplified that signals are transmitted by infrared rays. However, the present invention is not limited to this, and other wireless transmission methods may be used as long as signals can be transmitted. Further, the video display device 82 and the mask 83a may be connected by a wired cable capable of transmitting and receiving signals.

  As shown in FIG. 2, the mask 83a has the following configuration. The light receiving unit 6 receives an infrared light emission signal from the TV side and converts it into an electrical signal. The decoding unit 7 compares the code data of the code holding unit 8a with the electrical signal from the light receiving unit 6, and generates a coincidence signal. The mask control unit 9a controls the mask based on the timing of the coincidence signal from the decoding unit 7.

  FIG. 3 schematically shows how the mask 83a is used. FIG. 3 shows a method for providing a mask function to existing 3D glasses. The function of the present embodiment can be used without changing the function of the existing glasses by simply attaching a mask layer (mask 83a, mask M) prepared separately from the shutter glasses 83 (shutter S).

  FIG. 6 is an explanatory diagram illustrating code transmission timing according to the embodiment. The code is sent every Tfrm as shown in FIG. The glasses side opens the left shutter at the timing of receiving the code, and opens / closes the left / right shutter at the predetermined timing.

The processing flow of the shutter control unit 9 is as follows.
ST1: The counter i, the left shutter release signal Lopen, and the right shutter release signal Ropen are initialized to 0. As described above, when the Lopen signal is “1”, the right-eye shutter is opened and closed with “0”. When the Ropen signal is “1”, the left-eye shutter is opened and closed with “0”.

ST2: As a result of comparison in the decoding unit, if the code matches the code, the process proceeds to (ST3), otherwise the process proceeds to (ST4).
ST3: The counter i is initialized with 0, and Lopen = 1 and Ropen = 0 are substituted. (At this point, the left shutter is open and the right shutter is closed)
ST4: The counter i is incremented by 1 (the increment unit may be associated with time or the like).
ST5: The counter i is compared with Tfrm / 2 and if it matches or exceeds (ST6), the process proceeds to (ST7), otherwise.
ST6: Substitute Lopen = 0, Ropen = 1 (At this point, the left shutter is closed and the right shutter is open)
ST7: The counter i is compared with Tfrm, and if it matches or exceeds (ST8), the process returns to (ST2) otherwise.
ST8: The counter i is initialized with 0, Lopen = 1 and Ropen = 0 are substituted (the left shutter is opened and the right shutter is closed at this point), and the process returns to (ST2).

  There is a signal waveform format which is a binary pulse waveform in an infrared remote controller or the like. For example, time transition of voltage level is used. Following the leader code (H section is 4.5 msec, L section is 4.5 msec), there are custom codes, data codes, and the like.

  FIG. 7 is a flowchart of control by the microcomputer (not shown) of the mask 83a. In the self-running state, the microcomputer enters the wait mode waiting for the code arrival by the timer from the sleep mode. Control is performed when it is determined that the signal received from the video display device 82 is an appropriate signal as will be described later.

  In the mask 83a, the microcomputer enters the wait mode for waiting for the arrival of the code by the timer (step S701), the infrared signal is received by the light receiving unit 6 from the mask signal light emitting unit 4a (step S702), and the microcomputer receives the rising edge of the reader code. Is detected (Yes in step S703), the normal mode for measuring the reader code is entered (step S704). The H section and L section of the reader code of the received light signal are measured (step S705), and if the reader code is appropriate (H section is 4.5 msec and L section is 4.5 msec) (Yes in step S706), the microcomputer sends a remote control signal. Judged as received. Subsequent to this determination, the custom code and the data code are decoded (step S707). If the code cannot be decoded (No in step S706), the microcomputer is again set to the sleep mode and the process is terminated. In addition, also when it determines with No by said step S703, a microcomputer is again set to sleep mode and it complete | finishes.

  In step S706, the time from when the leading edge of the leader code is detected until the clock operates stably is usually about 1 msec. Therefore, when measuring the H section of the leader code, this 1 msec is measured in advance. I do.

  Next, when it is determined in step S707 that the data is an appropriate code (Yes in step S708), the microcomputer performs mask control, but if it is not a remote control code (No in step S708), the microcomputer is again set to the sleep mode. To finish.

In the present embodiment, the brightness experienced is improved without manipulating the screen brightness. FIG. 5 is an explanatory diagram for explaining an effect example of the mask of the embodiment. (A) is a case without glasses, and (b) to (f) show a case where normal 3D glasses are attached and a view image by glasses with a mask. The range of effect is adjusted by automatically switching the mask range according to the distance and position of the television, or by manually switching the mask range. In addition, the masking method can be composed of a transparent / black binary method and a gradation method, and the gradation can be adjusted when gradation is applied.

  FIG. 10 is a configuration diagram illustrating a correction amount notification image according to the embodiment. FIG. 10 shows a method of adjusting the mask range by communicating the brightness of the viewing environment detected on the television side. That is, a code representing brightness information is transmitted from the video display device 82 to the mask M. A user who does not view a stereoscopic image may use only the mask M without the shutter S.

  FIG. 11 is a flowchart for determining a correction amount on the television side mainly including the microprocessor 10 according to the embodiment. In addition to the following, FIG. 11 shows that a function for adjusting the mask amount can be provided by communicating the distance to the glasses detected on the television side, the current time, and the like.

Step S13: It is determined whether a mask is necessary. If it is not set to mask or dark, it is not necessary.
Step S14: If it is determined in the previous step that a mask is necessary, it is determined whether the mode is a cinema mode.
Step S15: If the cinema mode is determined in the previous step, the mask amount is set brighter in order to make the video appear darker. This includes that there is double information in the frame packet video for side-by-side video such as broadcasting.

Step S16: If it is determined in step S14 that the cinema mode is not set, the mask amount is set to be dark.
Step S17: If it is determined in step S13 that a mask is not necessary, the mask is set to no.
Step S18: (Output) One of the settings from Step S15 to Step S17 is output to the display control unit 2.
Step S19: The display control unit 2 notifies the glasses (mask 83a) of the mask amount via the mask signal light emitting unit 4a, and returns to step S11.
FIG. 12 is a glasses side correction flowchart mainly including the mask control unit 9a of the embodiment.
Step S21: The decoding unit 7 receives information from the television at a predetermined timing.
Step S22: The mask control unit 9a determines whether the decoding unit 7 has received information from the television.
Step S23: If the information from the television cannot be received in step S21, the mask control unit 9a sets the mask release. This is the case when looking away from the TV.

Step S24: If the information from the television can be received in step S21, the mask control unit 9a determines the mask range.
Step S25: The mask controller 9a determines the mask amount.
Step S26: The mask controller 9a sets mask application.
Step S27: (Output) The mask controller 9a outputs the setting of either step S23 or step S26 as a mask, and returns to step S21.
FIG. 13 is a flowchart of mask range control mainly including the mask control unit 9a of the embodiment.
Step S31: A screen range reflected in the field of view of the glasses is measured.
Step S32: It is determined whether the television is in view.

Step S34: If it is not determined in step S32 that the television is in view, the mask is released.
Step S35: (Output) The setting in either step S33 or step S34 is output as a mask, and the process returns to step S31.
In the example of FIG. 13, the self-running process may be performed without using the signal from the television for the timing. Glassless 3D (popular name naked eye 3D) can also be used.
As described above, according to the present embodiment, a pair of stereoscopic TV and a mask share a code transmitted by infrared rays.
In this embodiment, an infrared signal is used, but it is clear that generality is not lost even if it is replaced with a radio signal such as a radio wave or an ultrasonic wave. Further, instead of the shutter glasses, for example, polarized glasses and a mask may be shared.

It is possible to improve the darkness of the image associated with wearing the conventional 3D glasses, and it is possible to correct the image using glasses, and has the following characteristics.
(1) Give 3D stereoscopic glasses a mask function (gradation / 2 values)
(2) Mask the area other than the part where the monitor is visible on the glasses side. (3) Superimpose the brightness information of the room detected on the TV side on the sync signal between the TV and glasses.

(6) If correction is not required, operate as normal 3D glasses (7) If the distance is known, volume control is possible (optional function)
(Effect of embodiment)
In the present embodiment, the brightness experienced is improved without manipulating the screen brightness. In the field of view through the glasses, the area other than the area where the image is reflected is darkened by the liquid crystal mask prepared separately from the shutter. By doing so, the luminance of the television apparatus with respect to the background becomes relatively high, so that it can be felt that the luminance is improved.

Further, the effect can be enhanced by automatically adjusting the mask range and mask amount to some extent according to the distance from the television apparatus, the brightness of the room sent from the television apparatus, and the distance from the glasses. In particular, the mask range may be fixed depending on where the television is in the field of view of the glasses, or a method of detecting the four corners of the television by attaching a small camera to the glasses can be used. It is also possible to narrow the mask range by detecting the user's position on the television side and communicating with the glasses side. The user's position can be detected on the body, face, glasses, mask, and the like.

  In addition, this invention is not limited to the said embodiment, In the range which does not deviate from the summary, it can implement in various modifications. You may comprise a mask and glasses integrally. Further, for example, the mask may be an optional form of glasses, and for example, the output of the decoding unit 7 may be output from the glasses to a terminal, and the output may be input to the mask to simplify the mask configuration.
