Detailed Description
The embodiment of the invention provides a display device and a working method thereof, which are used for solving the problem that the display device cannot automatically enter a sleep mode and saving energy.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The embodiment of the invention provides a display device, which comprises a display panel, a backlight module, an image acquisition unit and a control unit, wherein the image acquisition unit is used for acquiring images; the image acquisition unit is used for acquiring a user image in real time and transmitting the user image to the control unit; the control unit is used for receiving the user image, determining user state information by analyzing the user image, and controlling the display device to enter a power saving state when the user state information meets a preset condition.
Referring to fig. 2, a display device according to a first embodiment of the present invention includes: the display device comprises a display panel 201, a backlight module 202, an image acquisition unit 203 and a control unit 204;
the display panel 201 is used for displaying images.
The backlight module 202 is configured to provide a backlight source for the display device;
the image acquisition unit 203 is configured to acquire a user image in real time and transmit the user image to the control unit 204;
the control unit 204 is configured to receive the user image from the image acquisition unit 203, determine user status information by analyzing the user image, and control the display device to enter a power saving state when the user status information meets a preset condition.
When the user enters the sleep state or leaves the range capable of watching, the display device can judge according to the detected user state information and automatically enter the power-saving state without user setting, so that the influence on the rest of the user is avoided, and meanwhile, the energy waste can be reduced.
The working modes of the display device comprise: a normal play mode and a sleep mode; in the normal play mode, the display panel 201, the backlight module 202, the image acquisition unit 203 and the control unit 204 are all in a working state; in the sleep mode, the display panel 201 and the backlight module 202 are turned off, and the image acquisition unit 203 and the control unit 204 are still in a working state.
In this embodiment of the present invention, the user state information includes a ratio of a distance between upper and lower eyelids of the user to a length of a face of the user. Generally, when a user watches programs, the user blinks continuously, the ratio of the distance between the upper eyelid and the lower eyelid to the face changes when the user blinks, and the ratio of the distance between the upper eyelid and the lower eyelid to the face does not change or changes little after the user falls asleep. Therefore, by observing the change of the ratio of the distance between the upper eyelid and the lower eyelid of the user to the length of the face of the user, it can be determined whether the user is asleep and thus whether the display device needs to enter a power saving state.
The control unit 204 receives the user image from the image acquisition unit 203 and determines the ratio of the distance between the upper and lower eyelids of the user to the face length of the user. When the ratio of the distance between the upper eyelid and the lower eyelid of the user in the continuous multi-frame images to the face length of the user belongs to a preset range [0, A1], or when the ratio of the distance between the upper eyelid and the lower eyelid of the user in the continuous multi-frame images to the face length of the user belongs to a preset range (A1, A2], the user is considered to be in a sleep state, otherwise, the user is considered to be in a watching state;
for example, in two minutes, the ratio of the distance between the upper and lower eyelids of the user in the acquired image of the user to the face length of the user falls within the preset range [0, a1], or when the ratio of the distance between the upper and lower eyelids of the user in the image of consecutive multiple frames falls within the preset range (a1, a2], the user is considered to have entered the sleep state, whereas if the ratio of the distance between the upper and lower eyelids of the user in the acquired image of the user to the face length of the user falls within the preset range [0, a1] in part and falls within the preset range (a1, a2] in the other part, the user is considered to be in the awake state.
Wherein when the ratio is less than or equal to a1, the user's eyes are considered closed, when the ratio is greater than a1, the user's eyes are considered open, a2 is the ratio of the maximum distance between the user's upper and lower eyelids to the user's face length; generally, the length of a human face is about 20cm, and the distance between eyelids in an open state is about 1cm, so the values of a1 and a2 are 1/100 and 1/20, respectively. In addition, the values of A1 and A2 can be set by the user according to the face condition of the user.
In addition, the user status information may also be other information, such as the distance between the upper and lower eyelids of the user, or the area of the eye region of the user.
For example, the control unit 204 may further determine the eye region area of the user by analyzing the user image, and when the eye region areas of the user in the consecutive multi-frame images all belong to the preset range [0, B1], or when the eye region areas of the user in the consecutive multi-frame images all belong to the preset range (B1, B2), the user is considered to have entered the sleep state, otherwise, the user is considered to be in the watching state;
in three minutes, the eye area areas of the users in the collected user images all belong to a preset range [0, B1], or when the eye area areas of the users in the continuous multi-frame images all belong to a preset range (B1, B2), the users are considered to enter the sleep state, on the contrary, if in two minutes, one part of the eye area areas of the users in the collected user images belong to the preset range [0, B1], and the other part of the eye area areas belong to the preset range (B1, B2), the users are considered to be in the waking state;
wherein when the user's eye region area is less than or equal to B1, the user's eyes are considered closed, and when the user's eye region area is greater than B1, the user's eyes are considered open; b2 is the maximum value of the eye region area of the user; typically, the B1 value is 10-5Square meter, said B2 is 10-4Square meter. In addition, the values of B1 and B2 can be set by the user according to the self condition.
The control unit 204 may further determine current user status information by analyzing the user image to determine a ratio of the eye area of the user to the face area of the user, and control the display device to enter a power saving state when the user status information meets a preset condition. The method for determining the current user state information according to the ratio of the eye area of the user to the face area of the user is the same as the method for determining the current user state information according to the ratio of the distance between the upper eyelid and the lower eyelid of the user to the face length of the user, and details are not repeated here.
When it is determined that the user enters the sleep state, the control unit 204 sends a closing signal to the display panel 201 and the backlight module 202, and closes the display panel 201 and the backlight module 202, so that the display device enters the sleep mode; in the sleep mode, the influence of brightness and sound on the rest of the user can be avoided, and meanwhile, the energy waste can be reduced.
After the display device enters the sleep mode, the image acquisition unit 203 and the control unit 204 are still in a working state, the image acquisition unit 203 continues to acquire user images and transmit the user images to the control unit 204, and the control unit 204 continues to receive the user images from the image acquisition unit 203, analyze the received user images, determine the ratio of the distance between the upper eyelid and the lower eyelid of the user to the face length of the user, and determine the current user state information.
After the display device enters the sleep mode, when the control unit 204 detects that the user state information changes, the control unit 204 is further configured to send a start signal to the display panel 201 and the backlight module 202, and start the display panel 201 and the backlight module 202, so that the display device enters the normal play mode, and the user can see the play state of the current program without any operation after waking up.
When it is detected that the user status information is changed, the control unit 204 is further configured to clear the record of the user status information before the change, so that the control unit 204 is convenient to determine whether the user status information after the change meets the preset condition.
The second embodiment of the present invention further provides another display device, which has the same structure as the display device shown in fig. 2, and the difference between the two embodiments of the present invention is that in the display device provided in the second embodiment of the present invention, when the user status information satisfies the preset condition, the control unit 204 is configured to control the power of the display device to be automatically turned off, so that the entire display device is turned off. The power of the display device is turned off, which means that the display panel 201, the backlight module 202, the image acquisition unit 203 and the control unit 204 are all turned off, so that the display device provided by the second embodiment is more energy-saving than the display device provided by the first embodiment, but the display device cannot continuously detect the user state information after the power is turned off, and cannot realize the function of automatically entering the normal play mode after the user wakes up.
The display devices are respectively provided with an image acquisition unit and a control unit, and the image acquisition units are used for acquiring user images in real time and transmitting the user images to the control unit; the control unit receives the user image from the image acquisition unit, analyzes the received user image to determine user state information, and controls the display device to enter a power saving state when a user meets a preset condition.
