DESCRIPTION JP2001016514
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
display device such as a television monitor, and more particularly to a display device having a
function of recognizing an iris of a human eye and performing various operations based on the
recognition result. It was constructed in
[0002]
2. Description of the Related Art Generally, video and audio appearing on a display device such as
a television monitor can be viewed by any person who can view and listen. Therefore, a child or a
minor may view a screen or sound that is undesirable for education. It can be handled by turning
off the display device, changing the channel if it is a television broadcast, or stopping the
playback if it is a video, if the parents are close to them, but always the parents are children and
minors. You can not be with me.
[0003]
Heretofore, the following methods have been proposed as a method for preventing children and
minors from displaying an educationally undesirable screen.
[0004]
Japanese Patent Application Laid-Open No. 8-214278 shows that, among channels of CATV
03-05-2019

broadcasting, channels that are not desired to be shown to children and which are subject to
restriction can not be viewed unless a dedicated IC card is inserted. It is done.
[0005]
In Japanese Patent Application Laid-Open Nos. 10-108149 and 10-117331, video data from a
television broadcasting station and video signals reproduced by a VTR, etc., include regulatory
data, and the regulatory data is It is described that the display device detects and regulates
display, and releases the regulation when a password is input.
[0006]
Japanese Patent Application Laid-Open No. 9-93513 describes that a password is set in the
display device itself so that an image can not be viewed from the display device unless the
password is input.
[0007]
In addition, when an elderly person or a person with a distant ear is watched, the voice output
may be larger than that of a hearing person, which may cause trouble around the user.
In order to cope with such a problem, it is disclosed in Japanese Patent Application Laid-Open
No. 10-234094 that a speaker with high directivity is used to make the sound loud only at a
certain place.
[0008]
In addition, infants and children may watch very close to the display device, and even if they are
careful to leave the display device, they often come close at a while when they become obsessed
with the display screen. .
In order to prevent such a situation, it has been proposed to provide a sensor on the display
device and detect a warning when an infant or child approaches the screen (Japanese Patent
Application Laid-Open No. 8-65599). JP-Hei 9-107508, JP-A 60-103970, JP-A 4-19082).

[Problems to be Solved by the Invention] However, in the conventional method of restricting the
display of harmful images to children and minors by using an IC card or a password, an adult can
control a restricted program or a restricted screen. If, after releasing, the display device is left in
front of the display device for some reason, a child or a minor may watch the display screen.
At this time, if the child or the minor leaves the display device before the adult returns, the adult
will not notice at all that the child or the minor has watched.
[0010]
Also, according to the method of including the control information in the television broadcast
signal and the video signal of the video media, the harmful image is displayed as it is if there is a
video which does not comply with the rule in the provided video. It will be done.
[0011]
Also, the method of using a directional speaker for people with deafness or people who have a
deaf ear decides where to hear well, so when moving a place, you can hear well at the destination
location There is the inconvenience of having to reset to
[0012]
Also, the method of detecting and warning with the sensor that the display device is approaching
too close can be used to adjust the display device because it can not be distinguished whether the
person approaching the display device is an infant or an adult. There is a problem that a warning
is given to adults as well.

Hereinafter, embodiments of the present invention will be described with reference to the
drawings.
[0038]
(First Embodiment) As shown in FIG. 1, the display device of the first embodiment comprises a
display screen 1a, a speaker 1b and a power button 5, and an iris pattern of the eye of the viewer
4 And a central processing unit (CPU) 3 for controlling the display device 1 based on the
information acquired by the iris recognition camera 2.
[0039]
The iris recognition camera 2 comprises, as shown in FIG. 2, a fixed position information camera
2a for detecting the position of the eye of a person in front of the camera, a movable camera 2b
for enlarging and photographing an iris, and a camera illumination 2c. And have.
[0040]
Iris recognition is a method that has recently received attention as personal identification, and a
registered person is identified from an iris pattern formed in the human eye.
03-05-2019
8
The direction of the human eye is detected from the images of the two position detection
cameras 2a arranged on the left and right of the iris recognition camera 2, and the movable
camera 2b is in front of the camera by enlarging and imaging the detected direction. The iris of
the person's eye is photographed.
[0041]
Although the configuration of the CPU 3 will be described in detail in the second embodiment,
the CPU 3 is able to register the iris pattern of the person, the age, the auditory information
(whether the ear is distant or not) etc. In addition, an image pattern, a character pattern, and an
audio pattern are stored as control information in order to identify a screen (control screen) to be
controlled, such as a violence scene or a sexual depiction scene.
The CPU compares the image etc. displayed on the display device with the restriction
information, and when they are similar, identifies that the restriction screen is displayed on the
display device.
[0042]
FIG. 3 shows a flow chart of the operation of this display device.
Step 1: When the viewer turns on the power supply 5 of the display device 1, Step 2: The iris
recognition camera 2 is also turned on, and Step 3: Start operation.
[0043]
Step 4: Iris Recognition When the camera 2 acquires information on the iris pattern of the viewer
4, Step 5: The iris pattern information is transmitted to the CPU 3.
Information of a display image is also transmitted to the CPU 3.
03-05-2019
9
[0044]
Step 6: The CPU 3 compares the acquired iris pattern with the iris pattern of the registered
viewer information when the person of the acquired iris pattern is not identified, and the
matched iris pattern Is registered, the corresponding viewer information is obtained.
[0045]
Step 7: The CPU 3 compares the display image with the restriction information to identify
whether the display screen corresponds to the restriction screen, and in the case of the
restriction screen, from the viewer information of the viewer, Check if there is no need to restrict
viewing on the restriction screen.
Then, when there is no need for regulation, Step 8: The display image is displayed on the display
device 1.
[0046]
Also, in step 7, when it is not clear that there is no need to restrict viewing, ie when it is
recognized from the viewer information of the viewer that it is necessary to restrict viewing, and
in step 9, the viewer is not yet If it is registration, step 10: execute viewing restriction, step 11:
operate the channel control device to change the channel, and step 8: display the image of the
changed channel.
[0047]
Thus, in this display device, when the viewer 4 turns on the power button 5 of the display device
1, the iris recognition camera 2 operates to detect the iris pattern of the eye of the person in
front of the camera. Then, based on the iris pattern, information on registered viewers is
obtained.
[0048]
Also, when a harmful regulation screen appears to an infant or the like, whether it is a regulatory
screen or not is identified based on the already registered regulatory information, and viewing
restriction on the regulation screen is not possible from the information on the viewer. Change
the channel unless it is obvious you need it.
03-05-2019
10
[0049]
Therefore, for example, when an infant views a television broadcast on this display device, it is
possible to prevent the infant's eyes from touching a scene having an educational adverse effect,
such as a violent scene or a sexual depiction scene.
[0050]
When a viewer who is not registered in advance turns on the power supply 5 of the display
device 1, there is no iris information, so it is determined that the regulation is necessary, and the
regulation screen can not be viewed.
[0051]
As a method of enforcing the regulation, in addition to changing the channel, a method of
stopping the display or obscuring the display contents may be adopted.
[0052]
FIG. 4 shows the operation flow when this display device is a video reproduction device.
In this video playback apparatus, as compared with the flow chart of FIG. 3, when the power is
turned on and the tape is activated (step 21), the iris recognition camera starts operating and the
video image signal is input to the CPU 3 (step 25) And as a method of enforcing the viewing
restriction of the restriction image, the difference is that the warning display appears on the
display screen (step 31), but the other operations are the same.
[0053]
Further, in this display device, a method of turning off the screen may be adopted as a method of
viewing restriction.
[0054]
Although this display device uses the iris recognition camera to recognize the viewer, it is also
possible to specify the viewer using a device that recognizes voiceprints and fingerprints.
03-05-2019
11
[0055]
Further, by using the illumination 2c of the iris recognition camera 2 as the infrared illumination,
even when the viewer looks at the display device 1 in the late-night darkness, the viewer is
recognized and the viewer is identified with certainty. It is possible to restrict the viewing of the
regulated person.
[0056]
Second Embodiment In the second embodiment, the details of the CPU 3 of FIG. 1 will be
described.
[0057]
As shown in FIG. 5, this CPU uses a memory 8 used for control work, a viewing history storage
unit 8a for storing viewing history, a storage unit 8b for viewer information, and a character
pattern 8c representing restriction information. , A storage unit for storing an image pattern 8d
and an audio pattern 8e, and a regulation determination device 16 for determining the necessity
of viewing restriction, a warning device 12 for giving a warning, and a warning character display
screen 1a , The voice signal unit 14 for outputting warning sound to the speaker 1b, the channel
control device 7 for controlling switching of the channel, the timer 9 for measuring time, and
from the display screen to the viewer Distance sensor 10 detecting that the distance of the
distance is within a predetermined distance and outputting proximity information, and position
information storage device 11 storing proximity information output from distance sensor 10 And
a communication device 17 for transmitting data stored in the viewing history storage unit 8a.
[0058]
Further, a display image signal is inputted from the display device 1 to the restriction judging
device 16, and an iris pattern photographed from the iris recognition camera 2 is inputted.
[0059]
FIG. 6 shows a flow chart of the operation of the CPU.
Step 41: When the CPU is activated, Step 42: The restriction determination device 16 searches
the display screen, and Step 43: identifies whether or not the display screen has characters
similar to the restriction characters stored in the character pattern storage unit 8c. Do.
03-05-2019
12
[0060]
For example, as shown in FIG. 10, when the character pattern "for adult" is stored in the
character pattern storage unit 8c, when this character is displayed on the display screen 1a, the
display image is displayed on the restriction screen. Identified as applicable.
In addition, as the restriction information of the character pattern, other character patterns such
as slang, slang, etc., and “prohibit under 18 years old” displayed in movies and commercial
videos are included.
[0061]
Step 44: When the restriction information of the character pattern is not applicable, it is
identified whether or not there is an image similar to the image pattern stored in the image
pattern storage section 8d on the display screen.
[0062]
For example, as shown in FIG. 11, when a mask image such as a mosaic pattern is stored in the
image pattern storage section 8d, when the mosaic pattern is detected from the display screen
1a, the display image is displayed on the regulation screen. Identified as applicable.
[0063]
Step 45: When the restriction information of the image pattern is not applicable, the sound signal
outputted simultaneously with the display image from the speaker 1b includes a sound pattern
similar to the restriction sound stored in the sound pattern storage unit 8e. Identify if it is
[0064]
Step 46: When the restriction information of the audio pattern is not applicable, it is identified
whether XDS information representing the restriction information is detected from the video
signal.
[0065]
03-05-2019
13
The XDS information is regulation information that has recently been put on the video signal of
television broadcasting and VTR.
When this XDS information is included in the television broadcast signal 35, as shown in FIG. 13,
the video signal received by the receiver 37 is sent to the display screen of the display device
through the regulation information detection device 34. When the restriction information
detector 34 detects XDS information, it transmits it to the CPU 3.
When the XDS information is included in the video signal of the VTR, the video reproduction
device 38 separates the XDS information from the video signal, and the XDS information is input
to the restriction information detection device 34, and the restriction information detection
device 34 , Tell it to CPU3.
[0066]
Step 47: If no restriction information can be detected, a display image is displayed on the display
unit 1.
[0067]
Step 48: When the regulation information is detected in the steps 43, 44, 45 or 46, the
regulation judging device 16 judges the display screen as a regulation screen.
Then, if it is determined from the viewer information stored in the viewer information storage
unit 8b that viewing restriction is necessary, step 49: the warning device 12 is driven to display
warning characters on the display screen as shown in FIG. And step 50: drive the channel
controller 7 to change channels, and step 47: display an image of the changed channels.
[0068]
As described above, when the viewer is a minor, after displaying the warning, the channel is
switched.
03-05-2019
14
However, when the viewer is an infant, the channel is switched without displaying a warning.
[0069]
By such control, it is possible to identify a regulatory screen that adversely affects education and
make it invisible to infants and minors.
[0070]
It may be difficult to determine whether the display image corresponds to the restriction screen,
so in step 48, recognition of step 43 (character recognition), step 44 (image recognition) and
step 45 (voice recognition) The result may be multiplied to identify whether it is a regulation
screen or not.
[0071]
Also, when the time when viewer 4 starts viewing and the elapsed time are counted by timer 9,
and it can be identified from the viewer information 8b that the viewer is an infant, for example,
viewing after 8 pm It is also possible to restrict the viewing time of the child or to limit the
viewing time for a long time by setting the viewing time limit.
[0072]
When the display device 1 is a television broadcast receiver, the viewing channel and the viewing
time are recorded in the viewing history storage unit 8a in association with the detected viewer
information of the viewer, and the viewing record is recorded. The data is configured to be
transmitted to the broadcast station through the communication device 17.
By doing this, the broadcast station can count the information sent from each receiver to obtain
the audience rating.
[0073]
In this case, by recording the viewing channel and viewing time in real time, including the age,
gender, residence, occupation, etc., in the viewer information, and sending this viewer
information, viewing channel and viewing time data, More accurate and dense audience rating
can be calculated.
03-05-2019
15
[0074]
Also, by operating the iris recognition camera 2 at all times, it is possible to leave a more
accurate viewing record except when not sitting in the seat and not sleeping and not actually
watching. it can.
Further, by sending recording data in real time from the communication device 17, it is possible
to count the ever-changing rating.
[0075]
Third Embodiment In the third embodiment, the operation of the CPU for preventing the viewer
from coming too close to the display screen will be described.
[0076]
The configuration of the CPU is as shown in FIG.
The distance sensor 10 detects the distance to the viewer, and outputs the proximity information
to the position information storage device 11 when the distance becomes equal to or less than a
predetermined length, and the position information storage device 11 stores the proximity
information.
[0077]
The restriction judging unit 16 checks the position information storage unit 11 and, when
proximity information is recorded, a warning is issued when the viewer specified from the iris
photographed by the iris recognition camera 2 is an infant. The device 12 is controlled to provide
an audible alert to leave the television.
[0078]
FIG. 7 is a flow chart showing the operation at this time.
03-05-2019
16
Step 51: When the viewer turns on the power supply 5 of the display device 1, step 56: The
distance sensor 10 also turns on and starts measuring the distance to the viewer.
[0079]
Step 52: The iris recognition camera 2 is also turned on, and Step 53: The image pickup
operation is started.
[0080]
Step 54: Iris Recognition When the camera 2 obtains the information on the iris pattern of the
viewer 4, the step 55 transmits the iris pattern information to the CPU 3.
Further, the distance sensor 10 outputs proximity information when the distance to the viewer is
equal to or less than a predetermined length, and this information is stored in the position
information storage device 11.
[0081]
Step 57: The CPU 3 compares the acquired iris pattern with the iris pattern of the registered
viewer information and matches the iris pattern when the person of the acquired iris pattern is
not specified. Is registered, the corresponding viewer information is obtained.
[0082]
Step 58: The CPU 3 confirms the data stored in the position information storage unit 11. If the
proximity information is stored, the viewer identified from the iris pattern is an infant or an
unregistered person. If yes, step 61: execute viewing restriction, and step 62: warn the sound
output from the speaker 1b so as to leave the display screen.
[0083]
If it is determined in step 58 that the viewer identified from the iris pattern is a display device
manager, the process proceeds to step 59 where the display is continued and no warning is
issued.
03-05-2019
17
[0084]
Thus, in this device, when the infant looks close to the display screen, it can warn to leave the
screen.
In addition, when the display device manager approaches the display device for adjustment, the
warning can not be issued.
[0085]
Further, in this device, not only the warning to the viewer but also the birthday and the
anniversary are set as the viewer information, for example. If it falls on a day, you can make a
special display on the display screen or play a message.
[0086]
Fourth Embodiment In the fourth embodiment, a case where a display device is used as a device
for transmitting a message or a message to a specific person will be described.
[0087]
This apparatus, as shown in FIG. 9, is provided with a message storage device 19 for storing
messages on the display device 1.
This message storage device 19 has a recording / reproducing mechanism built in the iris
recognition camera shown in FIG. 2, and on its surface, in addition to the position detection
camera 2a of the iris recognition camera and the iris information acquisition camera 2b, A record
button 19e, a play button 19f, a stop button 19g, a microphone 19a, and a message lamp 19d for

03-05-2019
18
presses the record / record button 19e to describe the message.
At this time, when it is confirmed from the iris pattern of the viewer A that the viewer A is
registered, the message storage device 19 records the viewer A and records a message.
When the recording / recording is completed, the viewer A displays a list of registered viewers
on the display screen, and specifies the viewer B to which the message is to be sent.
[0089]
The message storage unit 19 identifies the viewer who is in front of the display device by the iris
pattern in order to convey the message, and confirms the viewer B who is the destination of the
message, and blinks the message lamp 19d. .
When the viewer B presses the play button 19f after noticing the message lamp 19d, the
playback image of the viewer A is displayed on the display screen, and the message of the viewer
A flows from the speaker 1b.
