1. Technical Field
The present disclosure relates to televisions, and particularly, to a television with a function of switching television programs and a related method.
2. Description of Related Art
A remote control is usually used to switch television programs of a television. However, televisions in public places, such as a waiting hall, cannot be operated by an audience to select a preferred television program, therefore, the programs currently on those television might be less attractive to certain audience.
Many aspects of the present disclosure should be better understood with reference to the following drawings. The units in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding portions throughout the several views.
Embodiments of the present disclosure are described, with reference to the accompanying drawings.
The setting module 10 classifies television programs of the program table into different types, such as sports programs and news programs, for example. The setting module 10 further classifies audiences according to the number of people, the ratio of men to women, and an average watching time. The average watching time is divided into three time duration. The first time duration is watching 0˜15 minutes, the second time duration is 15˜30 minutes, and the third time duration is more than 30 minutes.
The setting module 10 further defines relationships between different types of audiences and different types of television programs. Each type of audience corresponds to one type of television program. For example, an audience having a large number of people corresponds to a news program, an audience having more men than women corresponds to a sports program, and an audience having more women than men corresponds to an entertainment program. An audience having an average watching time within the first time duration corresponds to a television program having a short program duration, an audience having an average watching time within the second time duration corresponds to a television program having a medium program duration, and an audience having an average watching time within the third time duration corresponds to a television program having a long program duration.
The image capturing control module 11 directs the image capturing unit 23 to capture an image at every preset time interval.
The face recognition module 12 recognizes faces in the captured images to generate a face recognition result. The face recognition result includes the number of audience members, the number of females in the audience, the number of males in the audience, and an average watching time of the audience. A detailed method for computing the average watching time of the audience is described as following: computing a watching time of each person in the audience according to the preset time interval for capturing two adjacent images; and computing the average watching time according to the watching time of each person in the audience.
The determining module 13 determines whether or not a condition for switching television programs is met according to the face recognition result. When a change of the number of audience members is equal to or greater than a first preset value, such as from two people to ten people, the determining module 13 determines that a first condition for switching television programs is met. When a change of a ratio of male-female audience members is equal to or greater than a second preset value, the determining module 13 determines that a second condition for switching television programs is met. When the average watching time of the audience members changes from one average watching time within a time duration to another average watching time within another time duration, the determining module 13 determines that a third condition for switching television programs is met.
When one condition for switching television programs is met, the searching module 14 searches within the program table to find a currently aired television program that is suitable for the current audience according to the defined relationships. In this embodiment, a priority level of the first condition is lower than the second condition but higher than the third condition. That is, when the first condition, the second condition, and the third condition are simultaneously met, the searching module 14 chooses a television program that is suitable for the current audience according to the second condition.
The switching module 15 automatically switches the channel of the television 200 to a channel playing the found television program.
In step S300, the setting module 10 classifies television programs of the program table into different types, classifies audiences into different types, and defines relationships between different types of audiences and different types of television programs.
In step S301, the image capturing control module 11 directs the image capturing unit 23 to capture an image at every preset time interval.
In step S302, the face recognition module 12 recognizes faces in the captured images to generate a face recognition result.
In step S303, the determining module 13 determines whether a condition for switching television programs is met according to the face recognition result. If one condition for switching television programs is met, the procedure goes to step S304. Otherwise, the procedure returns to step S302.
In step S304, the searching module 14 searches within the program table to find a currently aired television program that is suitable for the current audience according to the defined relationships.
In step S305, the switching module 15 switches the channel of the television 200 to a channel playing the found television program.
Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
