FIG. 3 is a flowchart of a preferred embodiment of a remote control method based on face detection. The remote control method includes the following steps: as shown in step 310, at first, at least one condition parameter is set. As shown in step 320, according to an operation mode of the multimedia system, at least a part of a human face is detected by a detection device, and a human face image signal is output accordingly. As shown in step 330, according to the face image signal, at least a part of the detected face is analyzed to generate a plurality of corresponding characteristic parameters. As shown in step 340, the characteristic parameters are compared with a condition parameter associated with at least one control operation of the operation mode to generate a comparison result. Next, as shown in step 350, at least one indication signal is generated to the multimedia system according to the comparison result.

In FIG. 3 , step 310 sets at least one condition parameter before step 320 , which is only one implementation manner. Step 310 can also be performed at the same time as or after step 320 is performed. However, in actual operation, the condition parameter in step 310 may be preset data, and does not need to be set during operation. In another practical operation mode, the multimedia system automatically sets or adjusts conditional parameters according to the needs of the operation mode during operation. In addition, the condition parameter can also be set by the user. In summary, the condition parameter is associated with at least one control operation of an operation mode of the multimedia system.

In the following embodiments of the present invention, the multimedia system may have one or more operation modes. Hereinafter, firstly, an embodiment of the remote control method of the present invention is disclosed by taking the operation mode as a playback mode as an example; then, another embodiment of the remote control method of the present invention is disclosed by taking the operation mode as a command option mode. Please note that the setting of the relevant condition parameters can be actually operated in different ways; therefore, the execution sequence of the steps of setting the condition parameters described in the following embodiments can also be actually operated in various orders or ways as described above .

FIG. 4A is a flowchart of an embodiment when a face detection-based remote control method is applied to a playback mode of a multimedia system.

As shown in step 410, the setting condition parameters include: (1) the number of viewers N _a , (2) the delay time T _d and (3) the threshold p% of the audience who did not leave the seat, and are related to the "play" and "stop" of the play mode. ", "Pause" operations are associated. As shown in step 420, according to the playback mode, the detection device detects the existing viewer's face and at least the eyes of the face to output a human face image signal. As shown in step 430, according to the face image signal, the detected face and at least a part of the face are analyzed to generate corresponding characteristic parameters including: (1) the number of faces and (2) the number of open eyes. As shown in step 440, compare the characteristic parameter generated according to the face image signal with the condition parameter related to at least one control operation of the playback mode to generate an indication signal to the multimedia system. In addition, after step 440 is executed, an embodiment of the method may start from step 420, repeatedly perform detection, and continue to generate an indication signal to the multimedia system.

Step 430 of the embodiment of this case takes the characteristic parameters (1) the number of human faces _Nf and (2) the number of open eyes _Ne as an example, and in step 440, different comparison methods can be implemented according to the two characteristic parameters to generate instructions signal to the multimedia system. Please refer to FIG. 4B , which is a flowchart of an embodiment of step 440 . For the convenience of explanation, the number of viewers N _a is 5, the delay time T _d is 10 minutes, and the threshold p% of the audience who has not left the seat is 80% as an example.

In FIG. 4B , as shown in step 441, first compare whether the number of human faces N _f is substantially greater than or equal to a percentage of the number of viewers Na, for example, determine whether the number of human faces _{N f obtained} by analysis (for example, 4) is greater than Or equal to (N _a ×p%), that is, (5×0.8)=4 people. If so, then execute step 442 to determine whether the number of opened eyes _Ne is substantially greater than or equal to another percentage of the number of viewers _Na , for example, whether the number of opened eyes _Ne (such as 8 eyes) obtained by judging analysis is greater than Or equal to (2N _a x p%), ie (2 x 5 x 0.8) = 8 eyes. If the comparison result in step 442 is yes, the generated indication signal represents a “play” operation, as shown in steps 447 and 460 .

In step 441 or 442, if the result is negative, step 443 is executed to determine whether the number N _f of detected faces is 0. If yes, enter step 444 to determine whether the pause has started and the delay time T _d has elapsed. If the judgment result of step 443 or 444 is negative, the generated indication signal represents a “pause” operation, as shown in steps 449 and 460 .

If the result of step 444 is yes (for example, it has been paused for 11 minutes), then the generated indication signal represents the "stop" operation, as shown in steps 448 and 460 .

In FIG. 4A and FIG. 4B mentioned above, the operation behavior of the multimedia system is changed based on the face and its parts according to the natural behavior of the person. For example, when the number of viewers and the number of opened eyes meet the requirements, the multimedia system will automatically start playing, as shown in steps 441 , 442 , 447 and 460 . For another example, when a part of the audience temporarily leaves the seat for some reason, and there are many people leaving the seat, the multimedia system will automatically pause the playback, as shown in steps 443 , 444 , 449 and 460 . However, if the number of viewers N and the number of opened eyes _Ne still do not meet the requirements after a delay time _Td , for example, 10 minutes, the multimedia system stops playing, as shown in steps 444, 448 and 460.

In the embodiment described above in FIG. 4A and FIG. 4B , three conditional parameters and two characteristic parameters are used as an example to illustrate how to change the operation behavior of the multimedia system. However, at least one conditional parameter can also be used to change the operation behavior of the multimedia system based on at least a part of the face or a human face. For example, detect the face of the audience that exists, and judge whether there are two audiences; _If so, then generate an indication signal to the multimedia system to start playing; Whether the number of faces N _f is greater than or equal to 2. For another example, the number of viewers Na of the condition parameter _is 2, and the characteristic parameter is the number of open eyes _Ne of the eyes, and it is judged whether the number of open eyes _Ne of the existing audience is greater than or equal to the number of viewers _Na of the condition parameter, and then Determines whether to instruct the multimedia system to start playback. For other human face parts or various combinations of human face parts, the above method can also be used as the basic source for changing the operation behavior of the multimedia system, so as to achieve the purpose of controlling the multimedia system.

Thus, the above-mentioned embodiment can be called an intelligent control method, that is to say, the remote control system can automatically send an instruction signal to adjust the operation of the multimedia system according to the actual detection result without the need for the user to give instructions.

Next, another implementation of the remote control method of the present invention is disclosed by taking the operation mode of the multimedia system as a command option mode. Please refer to FIG. 5 , which illustrates an embodiment of a face detection-based remote control system applied to a command option mode of a multimedia system according to the present invention.

When the multimedia system is in the command option mode, the display device 520 displays one or more options for the user to select. The user only needs to focus on one of the objects representing the options, such as an image, a block, or an area on the screen. Or the area of text, if the time that the eye gazes on meets corresponding conditions, for example, when eyeballs gaze on a remote control option for more than or about 3 seconds, the purpose of selecting this option can be realized.

In FIG. 5 , the user is represented by eyes or eyeballs 500 , and the options displayed by the display device 520 are, for example, options 521 and 522 .

Please refer to FIG. 3 and FIG. 5 at the same time to illustrate the remote control method of this embodiment. As shown in step 310, a fixation time threshold T _F0 is set as a condition parameter to be associated with the command selection operation in the command option mode. As shown in step 320, the existing human face and the eye part of the human face are detected, and a human face image signal is output accordingly, wherein eye tracking technology, such as eyeballs tracking and location technology (eyeballs tracking and location) can be used. As shown in step 330, according to the human face image signal, the detected human face and the eye part of the human face are analyzed to generate a plurality of corresponding characteristic parameters. marked), and the fixation time T _f of the direction the eye is looking at.

Then, in step 340, it is first judged whether the direction the eyes are looking at points to the display screen of the display device 520; One represents the option of remote control, such as option 522 in FIG. 5 . If the direction the eyes are looking at corresponds to an option representing the remote control, then it is judged whether the fixation time T _f of the direction the eyes are looking at is greater than or equal to a fixation time threshold T _F0 , such as about 3 seconds, to generate a comparison result.

In step 350, if the comparison result of step 340 is yes, that is to say: the direction that this eye is staring at corresponds to a representative remote control option and the gaze time T _f (such as about 3.7 seconds) of eyes is greater than or equal to a gaze time threshold T _F0 (for example, about 3 seconds), an indication signal is generated to represent the selection of the remote control option.

In the above-mentioned sub-step 340 of this embodiment, the detection device 540 and the image analysis and instruction generation unit 550 can obtain the direction and distance from the detection device 540 to the face or eyes, as shown by arrow 580, and the direction and distance the eyes are looking at. direction, as indicated by arrow 590. In addition, whether the direction the eyes are looking at falls on a certain option of the display screen can be realized by means of table lookup or geometric calculation in space. For example, a look-up table is established in advance, expressing the corresponding relationship between the various directions the eyes are looking at (as shown in angles) and each area on the screen (as shown in numbers), so that through the look-up table Get the image area corresponding to a certain direction the eyes are looking at.

According to the above-mentioned embodiment of the remote control method carried out in the command option mode, various applications of other relevant options can be derived as follows:

For example, when the positioning of the eyeball exceeds the fixation time threshold T _F0 on "next" or "previous", the indication signal means that the currently playing picture, or such as a program or track, will be changed. Continue for the next segment or return to the previous segment until the next playback option starts to execute. When the position of eyeball positioning is no longer on any remote control option, the execution of this function will stop.

When the positioning of the tracking eyeball is in "fast forward" (forward) or "reverse" (backward), as shown in the options 521 and 522 in Figure 5, after exceeding or equal to the fixation time threshold T _F0 time, it will start to fast forward or reverse the picture , and when the eyeball positioning is still on the remote control option when the function starts to execute, speed up the fast forward or reverse speed, and continue the function of the remote control option until the function of the next remote control option starts to execute, or when the eyeball positioning The function stops executing when the position is no longer on any remote control option.

When the positioning of the tracking eyeball exceeds or equals the fixation time threshold T _F0 time on the volume option, such as the option of the "+" sign in Figure 5, it will start to increase (or decrease, corresponding to the option of the "-" sign) to play Volume, continue the function of this remote control option until the function of the next remote control option starts to execute, or stop executing this function when the position of the eyeball is no longer on any remote control option.

Eye tracking technology can also use the selection of different remote control options on the control menu (menu). For example, there are 10 remote control options, but the screen of the display device can only present 5 remote control options at a time, then the technology of eye tracking and positioning can be used for remote control The operation of option page changing, and if the menu that does not need the remote control option appears on the display screen when watching multimedia playback, the menu can also be closed or hidden by using the eye tracking positioning technology.

In addition, in actual operation, in each embodiment of the above-mentioned remote control method, such as steps 330 to 350 or corresponding steps can be actually operated with a software program or program function, and then cooperate with a recording condition parameter and remote control function and The database or data structure of its association relationship is realized. In addition, it can also be implemented in hardware or firmware, or in a mixed manner.

The face detection-based remote control system and its method for use in multimedia systems disclosed in the above-mentioned embodiments of the present invention and the multimedia system, according to the natural behavior of a certain part of the human body, associates with the operation of the remote control multimedia system as a An indication signal is generated to an underlying source of the multimedia system, thereby changing an operational behavior of the multimedia system. In this way, the method of operating the multimedia system will become easier and more direct, and an intelligent control method can be derived based on this, that is to say, the remote control system can automatically issue instructions based on the actual detection results without the need for the user to give instructions in person. Indicating signals to adjust the operation of the multimedia system.

In summary, although the present invention is disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention is therefore defined by the scope of the appended claims.
