TV power saving device combined with eye detection

The present invention relates to a television power saving device combined with eye detection, and more particularly to a power saving device for controlling the blinking action of a human body to control the television to automatically turn off.

Nowadays, the pace of social life is fast and busy, and the work pressure is high. Many people spend a lot of time in front of the TV in order to relieve the pressure. Because of the long time watching the screen, and the fatigue after work, they often fall asleep when watching TV, causing the TV to be forgotten. As a result of energy loss and financial loss, it is also easy to reduce the life of the TV.

A method flow diagram for implementing a television sleep mode function as disclosed in U.S. Patent No. 5,894,331, which is characterized in that a user sets a sleep mode time in advance, and the television enters a sleep mode at this time and is on the screen. The remaining time is displayed on the top (eg 60 minutes). The TV will then gradually reduce the remaining time and display it on the screen at a predetermined time interval (eg 10 minutes) (eg 50 minutes, 40 minutes...10 minutes). When the remaining time reaches zero, the system detects whether there is a key input response from the user. If not, the user is considered to have fallen asleep and automatically turns off the TV.

However, this predecessor only implements the TV sleep mode function by timing off. The main disadvantage is that during the sleep mode function of the TV, the user needs to pay attention to the remaining time of the sleep mode displayed on the TV screen, but the user is in a fatigue state. It is often difficult to concentrate and pay attention to the remaining time of the sleep mode displayed on the screen, causing the TV to suddenly turn off without warning.

To this end, a manufacturer has developed a circuit and method for realizing a television smart sleep mode function, such as the Republic of China Patent Publication No. I353784, which is a circuit and method for realizing a television smart sleep mode function, the circuit comprising: A control chip for controlling the output of the television audio and video signals; and an audio amplifier for reducing the intensity of the input audio signal. The control crystal moon further includes a digital signal processor, and a timer, a PWM output port, and an LVDS output port respectively connected to the digital signal processor; and the audio amplifier is connected to the PWM output port. The digital signal processor controls the audio amplifier through the PWM output to achieve sound control, and controls the display device through the LVDS output to achieve brightness control. By using the method of the invention, when the television is performing the sleep mode function, the system gradually reduces the volume and brightness step by step before turning off the television. After several times of volume and brightness decrement, if the system does not detect the user key input, then Will turn off the TV in vain.

There are still deficiencies in the use of the previous case, the reasons are:

1. Although the above predecessor provides the sleep mode, the user can automatically turn off the TV when the user has no button input. However, if the user is watching the channel, there is no button input at this time, causing the system to recognize that no one is watching the TV. Therefore, the television is suddenly turned off without warning, which causes inconvenience to the user.

2. The above judgment of the previous case is based on the use of the user's button end. In order to prevent the TV from automatically turning off the input button from time to time, the user does not disclose the use of the camera to detect the human body image, resulting in practicality. insufficient.

3. The above case requires the sleep mode function or the sleep mode time to be set by the TV to provide the function of automatically turning off the TV. If the user does not set the sleep mode function in advance, the power saving function can not be automatically turned off.

Therefore, in order to further effectively judge whether the user is in a sleep state or leave, thereby solving the problem that it is difficult to effectively control the automatic power-saving shutdown of the television, the creator is devoted to research and proposes a television power-saving device combined with eye detection, which is installed. The power saving device for controlling the television is turned off on a television, and the television power saving device combined with the eye detection includes: a face detection module, the face detection module captures and outputs a first The dynamic image is a dynamic image of the human eye; a processing identification module includes an image comparison unit and a control unit electrically connected to each other, and the image comparison unit signal is coupled to the face detection mode The group is configured to receive the first motion image, where the image comparison unit pre-stores a second motion image of a plurality of eye movements of the eye, and when the first motion image does not conform to the second motion image, the image The comparison unit outputs a control signal to the control unit, and the control unit is electrically connected to the television for controlling the power of the television.

Further, the face detection module includes an infrared camera and an image recording unit electrically connected to each other, the infrared camera captures the first motion image, and the image recording unit outputs the first motion image.

Further, the control unit is provided with a timer, which can set a preset value, and when the control unit receives the control signal, generates a timing value, the timing value reaches the preset value and the control unit continues to receive When the control signal is received, the control unit cuts off the power of the television; and the control signal is interrupted and outputted to the control unit, the timing value is reset to zero, and the face detection module is further executed to capture and output the foregoing. The first motion picture.

This creation has the following effects:

1. The face detection module provided by the creation office has an infrared camera capable of performing dynamic image capture when the indoor light is not bright, and matching the image comparison unit to make a blink comparison, compared with the traditional Timed shutdown and user-side response to shutdown mode are more practical.

2. The television power saving device combined with the eye detection of the present invention captures and outputs a first motion image through the face detection module, and the first motion image is a motion image of the human eye, and then The image comparison unit pre-stores the second dynamic image corresponding to the dynamic blinking action of the human eye to perform image comparison. If the user is tired or falls off the detection range, the device cannot compare the corresponding dynamic image, that is, After the scheduled time arrives, the TV power is automatically turned off, so as to effectively control the TV power off time and save power.

The technical features and the enhancements of the present invention are clearly shown in the following embodiments. First, the embodiment of the present invention is shown in the first figure. The embodiment includes:
