Description

  The present invention relates to a television receiver, and more particularly to a television receiver having a demonstration function.

  Some television receivers for store display have a demonstration function. There are television receivers with a demonstration function that always operate the demonstration function and those that operate at regular intervals. Since such a demonstration function repeatedly operates the demonstration regardless of whether or not a person is present near the television receiver, there is a problem that the person is not interested.

  As a countermeasure for this problem, there is an electric device that operates a demonstration function only when a person is present in the vicinity of the electric device and is not using the device (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 5-79589

  Television receivers displayed at stores are often viewed in the vicinity of the equipment without operating the equipment to check the quality of the video.

  However, in Patent Document 1, since the human body detection switch is always in an on state while a person is present in the vicinity of the electric device, the demonstration function is repeated unless the device is operated. Therefore, if the demonstration is repeated at all times, there is a problem that it is not possible to see the video during normal operation of the television receiver.

  The present invention has been made to solve these problems, and provides a television receiver that operates normally without repeating the demonstration even if a person is present near the television receiver at the end of the demonstration. The purpose is to do.

  In order to solve the above-described problems, a television receiver according to the present invention has a demonstration function, a demonstration function switch that controls the demonstration function on / off, and a human body motion that detects the motion of the human body by a human body detection sensor. When the human body motion detector detects that the state of the detection area has changed while the demonstration function switch is on, the demonstration function is activated for a predetermined time, and after the demonstration function is activated for the predetermined time. It is characterized by normal operation.

  The present invention is a television receiver having a demonstration function as set forth in claim 1, wherein the demonstration function switch controls the demonstration function on / off, and the human body motion detection unit uses a human body detection sensor to detect the human body. When the motion detection is detected and the human body motion detector detects that the state of the detection area has changed while the demonstration function switch is on, the demonstration function is activated for a predetermined time. Since it operates, even if a person is present near the television receiver at the end of the demonstration, normal operation can be performed without repeating the demonstration.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an external view of a television receiver according to an embodiment of the present invention. As shown in FIG. 1, the television receiver 11 includes a pyroelectric infrared sensor 12 on the front surface. The pyroelectric infrared sensor 12 can detect whether a person exists in the detection range by detecting a temperature change in the detection range.

  FIG. 2 is a control block diagram according to an embodiment of the present invention. The demonstration function switch 21 controls on / off of the demonstration function 25 and can be switched manually. The demonstration function switch 21 is operated on the menu screen of the television receiver 11 or switched according to the type of the B-CAS card. For example, when a B-CAS card is used, the demonstration function switch 21 can be turned on only when a dedicated B-CAS card is inserted. Any operation means may be used as long as the demonstration function 25 can be turned on / off.

  The human body motion detection unit 22 detects the motion of the human body using the human body detection sensor, and when the human body motion detection unit 22 detects that the state of the detection area has changed, that is, the person moves from outside the detection area into the detection area. Turns on when moved and / or moved outside the detection area from within the detection area. Therefore, a state in which a person continues to exist in the detection area is not regarded as a change in the state of the detection area. Although the pyroelectric infrared sensor 12 is used as a human body detection sensor, any sensor may be used as long as it can detect human movements. The device operation detection unit 23 detects whether a key provided on the main body of the television receiver 11 or a remote control key is pressed.

  As shown in FIG. 2, when the demonstration function switch 21 is on and the human body motion detection unit 22 detects that the state of the detection area has changed, the demonstration function 25 is operated by the control unit 24. When the device operation detection unit 23 detects that a key or a remote control key provided on the main body of the television receiver 11 is pressed while the demonstration function 25 is operating, the control unit 24 stops the demonstration function 25. On the other hand, if there is no detection by the device operation detection unit 23 while the demonstration function 25 is operating, the demonstration function 25 is stopped after being performed for a predetermined time. After the demonstration function 25 is stopped, normal operation is performed. The operation contents of the demonstration function 25 include displaying on the television receiver 11 an image that can publicize the features of the product, increasing the volume level, and moving the television receiver 11 left and right by a swivel. .

  FIG. 3 is a diagram illustrating a detection area of the human body motion detection unit 22 in the embodiment of the present invention. As shown in FIG. 3, the detection areas are intermittently arranged at predetermined intervals in the horizontal direction on the front surface of the television receiver 11, and can be arbitrarily determined according to the type of Fresnel lens attached to the pyroelectric infrared sensor 12. It is.

  As shown in FIG. 4, in the television receiver 11 during normal operation, when a person moves from outside the detection area into the detection area, the human body motion detection unit 22 is turned on, and the demonstration is operated for a predetermined time.

  As shown in FIG. 5 and FIG. 6, in the television receiver 11 at the end of the demonstration, when a person is present in the detection area but is stationary or moves only within the detection area, human body motion detection is performed. Since the unit 22 is not turned on, the demonstration does not operate. After the demonstration function 25 is stopped, normal operation is performed.

  As shown in FIG. 7, in the television receiver 11 at the end of the demonstration, when a person moves from the detection area to the outside of the detection area, the human body motion detection unit 22 is turned on, and the demonstration is operated again for a predetermined time.

  As shown in FIG. 8, in the television receiver 11 at the end of the demonstration, the human body motion detection unit 22 is not turned on regardless of whether the person moves or stops outside the detection area, so the demonstration does not operate. After the demonstration function 25 is stopped, normal operation is performed.

  As shown in FIG. 9, in the television receiver 11 at the end of the demonstration, when a person who has been outside the detection area moves again into the detection area, the human body motion detection unit 22 is turned on, and the demonstration is operated again for a predetermined time. To do.

  FIG. 10 is a flowchart of the operation of the television receiver 11 according to the embodiment of the present invention. In step S1, it is determined whether or not the demonstration function switch 21 is on. When the demonstration function switch 21 is off, normal operation is performed (step S9), and when it is on, the process proceeds to step S2. In step S2, whether or not a person has moved from outside the detection area of the pyroelectric infrared sensor 12 into the detection area is determined by the human body motion detection unit 22, and if it has not moved within the detection area, normal operation is performed (step S9). ) When the human body motion detection unit 22 detects that it has moved into the detection area, a demonstration is started (step S3). During the demonstration operation, in step S4, it is determined whether the device operation detection unit 23 is turned on by pressing the main body key or the remote control key of the television receiver 11, and if it is determined to be on, the demonstration is stopped and the normal operation is stopped. When the operation is started (step S9) and it is not determined to be on, the demonstration is ended after a predetermined time of operation (step S5). After the demonstration, in step S6, it is determined whether or not a person is present in the detection area. If there is no person in the detection area, the normal operation is performed (step S9). If there is a person in the detection area, the process proceeds to step S7. In step S7, it is determined whether or not a person existing in the detection area has moved out of the detection area. If it has not moved out of the detection area, normal operation is performed (step S8), and it is determined that the person has moved out of the detection area. The demonstration is started again (step S3).

  From the above, the demonstration starts when a person moves into the detection area of the human body motion detection unit 22, and can attract the attention of the person. Further, after a demonstration operation for a predetermined time, in a state where a person continues to exist in the detection area, the normal operation is performed without repeating the demonstration, so that it is possible to view an image during the normal operation. Furthermore, since the detection area is intermittently arranged at predetermined intervals in the horizontal direction on the front surface of the television receiver 11, when the person moves from the detection area to the outside of the detection area, the demonstration is started again to attract the attention of the person. It is possible to further increase the degree of attention.
