Hereinafter, embodiments of the present disclosure will be listed and illustrated.

In the stove system of the present disclosure, the detection unit can detect the user's motion performed within a predetermined range (within the range imaged by the imaging unit) as the motion of a moving object. Then, when the motion of the moving object detected by the detection unit is a candidate motion stored in the storage unit, the control unit executes a control command associated with the candidate motion. That is, if the user performs a predetermined candidate motion and causes the imaging unit to image the candidate motion, the user does not have to perform the operation of touching the gas stove by hand or the operation of touching the gas stove by hand is minimized. , The gas stove can be made to perform the desired control.

In the stove system of the present disclosure, the gas stove may include a plurality of marks provided at different positions within a predetermined range. The detection unit may detect a change in the detection state of a plurality of marks as an operation of a moving object in a plurality of captured images captured by the imaging unit.

In this configuration, when the detection state of a plurality of marks by the detection unit changes based on the movement of the user on the top plate, the change in the detection state of the plurality of marks can be detected as the movement of the moving object. Therefore, the system can be realized with a simple configuration in which a plurality of marks are provided on the gas stove. When trying to detect the movement of an imaged object by analyzing the captured image, the amount of processing during image analysis becomes relatively large. However, the stove system of the present disclosure can detect the movement of a moving object by detecting a change in the detection state of a plurality of marks, requires a relatively small amount of processing during image analysis, and makes a candidate movement more quickly. It is possible to determine whether or not it is.

In the stove system of the present disclosure, the plurality of marks may include a first mark and a second mark different from the first mark. The detection unit operates that the detection state of the second mark has changed before a predetermined time has elapsed after the detection state of the first mark has changed in the plurality of captured images captured by the image pickup unit. May be detected as.

In this configuration, when the state in which a hand or the like is held over the first mark changes to the state in which the hand or the like is held over the second mark within a predetermined time, "after the detection state of the first mark has changed". , The detection state of the second mark has changed before the predetermined time has elapsed. " Therefore, the movement of a moving object such as a hand can be easily detected based on the change in the detection state of the two marks. Further, since it is configured to determine whether or not the detection state of the second mark has changed after the detection state of the first mark has changed and before the predetermined time has elapsed, the detection time of the movement of the moving object is set to a predetermined time. It is possible to limit the time between the two, and it is possible to quickly determine whether or not an action such as a hand has been performed.

In the stove system of the present disclosure, the plurality of marks may include a group of marks composed of a plurality of marks arranged along a predetermined direction. The detection unit detects as the first operation that the detection state of each mark of the mark group changes in the order from one side to the other side in the predetermined direction in the plurality of captured images captured by the image pickup unit, and detects in the predetermined direction. It may be detected as the second operation that the detection state of each mark of the mark group changes in the order from the other side to one side. The storage unit may store the first candidate operation and the first command for increasing the thermal power in a state of being associated with each other, and may store the second candidate operation and the second command for decreasing the thermal power in a state of being associated with each other. good. The control unit executes the first command when the determination unit determines that the first operation detected by the detection unit is the first candidate operation stored in the storage unit, and the first operation detected by the detection unit. When the determination unit determines that the two operations are the second candidate operations stored in the storage unit, the second command may be executed.

In this configuration, the detection unit moves a hand or the like along a predetermined direction (arrangement direction of a plurality of marks) on the mark group, so that the detection state of each mark of the mark group changes in the order along the predetermined direction. Then, it is detected as the first operation that the detection state of each mark of the mark group changes in the order from one side to the other side in the predetermined direction, and each mark of the mark group is detected in the order from the other side to the other side in the predetermined direction. The change in the detection state of is detected as the second operation. The control unit executes the first command (command to increase the thermal power) when the first operation is the first candidate operation stored in the storage unit, and the second operation is the second candidate operation stored in the storage unit. If, the second command (command to reduce the firepower) is executed. Therefore, the user's movement of the image of sliding the operation part such as the heating power adjustment lever can be detected as the first movement or the second movement, and the heating power of the stove part is adjusted based on the intuitive user's movement. can do.

The control unit may determine one or more stove units to be executed by the control unit according to a predetermined determination method. Then, when the motion of the moving object detected by the detection unit is the candidate motion stored in the storage unit, the control unit follows the control command associated with the candidate motion in the storage unit. The control may be performed on the stove unit determined by the above determination method.

In this way, when the user performs the candidate operation, the control associated with the candidate operation can be selectively performed on the stove unit determined according to the determination method.

In the configuration using the determination method as described above, in the determination method, when only one of the stove units is in the ignition state, the stove unit in the ignition state is determined as the target for executing the control command. It may be a method of doing.

In this way, when only one stove unit is in the ignition state, the control associated with the candidate operation can be selectively performed on the stove unit.

In the configuration using the determination method as described above, in the determination method, when the operation for designating one or more stove units is performed by the user, the stove unit specified by the user is determined as the target for executing the control command. It may be a method of doing.

In this way, when an operation for designating one or more stove units is performed by the user, the control associated with the candidate operation can be selectively performed for the stove unit.

The cooking container Ta is configured as a bottomed cylindrical pot and stores a liquid (for example, water). The imaging region AR1 is an region imaged by the imaging unit 90, and an image of that portion is a region generated by the imaging unit 90. That is, an image reflecting the imaging region AR1 is generated by the imaging unit 90. In the present specification, the range in which the image pickup unit 90 captures an image is defined as a "predetermined range".

Each of the marks 21 to 27 in the lit state has an invariant position when viewed from the imaging unit 90, has a substantially circular shape, and has a constant brightness. That is, in the captured image obtained by capturing the imaging region AR1 in a normal state without the intrusion of moving objects such as hands and clothes, the images of the marks 21 to 27 have a constant position, a constant shape, and a constant brightness.

Each of the marks 21 to 27 is turned on when a predetermined lighting start condition is satisfied, and is turned off when a predetermined lighting start condition is satisfied. For example, each mark 21 to 27 lights up when the ignition operation is performed while all the stove units are extinguished (when the ignition operation is performed for any of the rotation operation units 6A, 6B, 6C, and 6D). It is possible to configure the stove to be in a state of being turned off when an operation is performed in which all the stove parts are put into a fire extinguishing state. Specifically, when the rotation operation unit 6A is operated to ignite the right stove unit 4A when none of the stove units is in the ignition state, each mark 21 to 27 lights up prior to the ignition of the right stove unit 4A. It is configured to turn off when the rotation operation unit 6A is operated to extinguish the fire of the right stove unit 4A when only the right stove unit 4A is in the ignition state. The marks 21 to 27 are turned on when the power of the system Sy is switched from the off state to the on state by the on / off operation of the predetermined power switch, and are turned off when the power is switched from the on state to the off state.

The communication unit 84 is a device that cooperates with the control circuit 10 to communicate with an external device by a known communication method (for example, a known wireless communication method such as an infrared communication method or a Bluetooth® communication method).

1-3. Command execution control Next, command execution control will be described. The command execution control shown in FIG. 7 is a control executed by the control circuit 10, for example, the control circuit 10 executes the command according to a program stored in the ROM 10B in response to the establishment of a predetermined start condition. The start condition is satisfied, for example, when the power supply of the system Sy is switched to the on state by the on operation of a predetermined power switch (when power can be supplied to each component from the power supply circuit 57). May be good. Further, when the start condition is satisfied, any one of the rotary operation units 6A, 6B, and 6C is used to ignite the gas burners 51, 52, and 53 while none of the gas burners 51, 52, 53 of the gas stove 1 is ignited. It may be when a predetermined ignition operation is performed on the stove. Alternatively, it may be when other conditions are satisfied, such as when a predetermined operation is performed on an operation unit such as an operation button.

In the command execution control according to the present embodiment, the control circuit 10 analyzes the image of the imaging region AR1 in the “predetermined range” captured by the imaging unit 90 after the start condition is satisfied. Specifically, the imaging unit 90 repeatedly images the imaging region AR1 at short time intervals after at least the above start conditions are satisfied, and repeatedly generates images in the predetermined range at short time intervals. On the other hand, the control circuit 10 acquires the captured images intermittently generated by the imaging unit 90 at predetermined intervals (for example, 1 second), and analyzes the captured images each time the captured images are acquired. ..

When the control circuit 10 starts the control of FIG. 7 in response to the satisfaction of the start condition, the control circuit 10 first transmits an imaging instruction to the imaging unit 90 via the communication unit 84 (step S11). Specifically, the control circuit 10 sends an imaging instruction (command signal) to the imaging unit 90 to cause the imaging unit 90 to perform an imaging operation. The imaging instruction is information that becomes a trigger for the imaging unit 90 to execute an imaging process (a process of imaging a predetermined range AR1), and is predetermined information.

When the imaging unit 90 receives an imaging instruction from the gas stove 1, the imaging unit 90 starts imaging, and the above-mentioned "predetermined range" (imaging) is performed at short time intervals every predetermined time (for example, several milliseconds to several seconds) until the imaging end condition is satisfied. Area AR1) is imaged. The imaging end condition may be, for example, that the power of the gas stove 1 is turned off, that a predetermined end operation is performed, or that all the stove parts are in a fire extinguishing state. Often, other conditions may be used. The image pickup unit 90 takes an image of a "predetermined range" (range of the imaging region AR1) every predetermined time (for example, 1 second), and obtains image data (imaging data for representing an image in the predetermined range) or the image data. The processing data and the like processed in the above are transmitted to the gas stove 1. The control circuit 10 acquires the image data or processed data obtained by processing the image data via the communication unit 84. For the processed data, for example, known processing such as noise removal, edge detection, shading adjustment, histogram adjustment, and color correction is performed on the captured image obtained by imaging with the imaging unit 90 by a predetermined known method. It is the data that was done. In addition, such processing data may be generated by the control circuit 10.

The imaging unit 90 can sequentially transmit the image data obtained by imaging every predetermined time (for example, 1 second) after receiving the imaging instruction given in step S11 to the gas stove 1. On the other hand, after step S11, in step S12, the control circuit 10 receives the image data transmitted from the image pickup unit 90 (step S12). Then, the control circuit 10 stores the received image data in the storage unit. As for the reception of the image data in step S12, one image data may be received or a plurality of image data may be received.

After step S12, the control circuit 10 receives a plurality of image data (for example, a plurality of images received within the latest fixed time) in step S13 up to that point (for example, the latest fixed period before the execution of step S13). Data) attempts to detect the movement of the moving object, and it is determined whether or not the movement of the moving body is detected. If the control circuit 10 determines in step S13 that no moving object has been detected from the plurality of image data received so far, the control circuit 10 performs the process of step S12 again. That is, the control circuit 10 repeats the process of step S12 until the motion of the moving object is detected in step S13, and continues to repeatedly acquire the image data transmitted from the imaging unit 90. In this configuration, the control circuit 10 corresponds to an example of a "detection unit".

The moving object is an object (however, an object other than the gas controller system 1) that moves in the region imaged by the imaging unit 90, and here, a plurality of objects in the same imaging range (specifically, the range of the imaging region AR1). In a plurality of captured images taken at different times, an imaged object whose relative position changes is detected as a "moving object". More specifically, in step S13, the control circuit 10 detects a change in the detection state of the marks 21 to 27 as the operation of the moving object in the plurality of image data.

The control circuit 10 analyzes a plurality of captured images accumulated within the most recent fixed time (for example, 5 seconds) of step S13, and determines whether or not the marks 21 to 27 can be recognized in each of the plurality of captured images. .. Whether or not the marks 21 to 27 can be recognized in each of the plurality of captured images can be determined by the same method as in known image analysis. For example, it is determined by known pattern matching whether or not a predetermined reference figure (for example, the same figure as each of the marks 21 to 27) exists in the captured image, and if it exists, the area is defined as the marks 21 to 27. It may be the area of 27. Alternatively, it is determined whether or not a region extending within a certain range is detected by predetermined color information (each numerical value of the three elements of color (RGB)) at a predetermined position in the captured image, and when it is detected. The area may be the area of the marks 21 to 27. Alternatively, it is determined whether or not a region having a certain brightness or higher and within a certain area range is detected at a predetermined position in the captured image, and if detected, that region may be used as a region of marks 21 to 27. good. In any case, it is possible to determine whether or not the marks 21 to 27 can be recognized by analyzing the captured image.

The control circuit 10 is changed from the state in which all the marks 21 to 27 are recognized in any of the plurality of captured images accumulated within the most recent fixed time (for example, 5 seconds) of step S13 (that is, any of them). If the mark is not recognized), it is determined that the movement of the moving body has been detected in step S13. On the other hand, the control circuit 10 detects the movement of the moving object when all the marks 21 to 27 are recognized in any of the plurality of captured images accumulated within the most recent fixed time (for example, 5 seconds) of step S13. Judge that it is not. If the control circuit 10 breaks if the movement of the moving body is not detected in step S13, the process proceeds to No and the process of step S12 is performed again. On the other hand, when the control circuit 10 determines that the movement of the moving body has been detected in step S13, the process proceeds to Yes and the process of step S14 is performed.

In step S14, the control circuit 10 determines whether or not the candidate operation is detected from the plurality of captured images accumulated within the latest fixed time (for example, 5 seconds) of step S13. In this configuration, the control circuit 10 corresponds to an example of a "determination unit". For example, the ROM 10B stores candidate motion specific information (hereinafter, also simply referred to as specific information) for specifying a predetermined candidate motion of a moving body (No. 1 to No. 4 in FIG. 8). The specific information is information that identifies the mode of change in the detection state of the marks 21 to 27. Specifically, the specific information may be character string data representing a change in the detection state of each mark 21 to 27 among a plurality of captured images captured at a plurality of different times, and may be a number or a symbol. It may be data such as. For example, in the ROM 10B, as a mode specified by the specific information, as shown in FIG. 8, "the detection state changes from the detection state to the non-detection state in the order of the mark 21 and the mark 22", and "the detection state in the order of the mark 27 and the mark 26". "Changes from the detection state to the non-detection state", "The detection state changes to the non-detection state in the order of the mark 25, the mark 26, the mark 25, the mark 26", "the mark 22, the mark 23 ... the mark 26, the mark 22, the mark 23 ... The detection state changes in the order of the mark 26 "and the like are stored.

As shown in FIG. 8, the candidate operation No. 1 is an operation in which a hand or the like is held in the order of the mark 21 and the mark 22. When a hand is held over the mark 21, the hand is interposed between the mark 21 and the imaging unit 90, and as shown in FIG. 9A, the mark 21 (mark represented as the imaged object P21 in the captured image). (See FIG. 9B)) is not imaged by the imaging unit 90. As shown in FIGS. 9A and 9B, the hand is represented as the imaged object H in the captured image. Therefore, the mark 21 changes from the detected state to the non-detected state. Subsequently, when the hand is moved to the right and the hand is held over the mark 22, the hand is interposed between the mark 22 and the imaging unit 90. As a result, as shown in FIG. 9B, the marker 22 (the marker represented as the imaged object P22 in the captured image (see FIG. 9A)) is not imaged by the imaging unit 90. Therefore, the mark 22 changes from the detected state to the non-detected state. When this example is adopted, in a plurality of images within the latest fixed time (for example, 5 seconds) of step S13, an image showing a state as shown in FIG. 9 (A) and a state as shown in FIG. 9 (B) are displayed. The images shown are generated in this order, and during the period during which these images are generated, the images are different from the other motion images (images different from the images of FIGS. 9 (A) and 9 (B), and any of them. When the image (the image in which the mark is not captured) is not generated, it is determined that the operation of the candidate operation No. 1 is detected in step S14, and the process proceeds to step S15. In this example, the mark 21 corresponds to the "first mark" of the present invention, and the mark 22 corresponds to the "second mark" of the present invention. Further, the mode specified by the specific information of the candidate operation No. 1 (first candidate operation) is "a marker group in the order from one side (left side) to the other side (right side) in a predetermined direction (direction in which the marks 21 to 27 are lined up). It corresponds to "the detection state of each of the marks 21 and 22 of 20 changes (first operation)". In this example, when a predetermined time (for example, 1 second) has not elapsed from the time when the non-detection state of the mark 21 is detected to the time when the non-detection state of the mark 22 is detected, "mark 21, mark 22". The condition of "changing from the detected state to the non-detected state in the order of" may be satisfied.

As shown in FIG. 8, the candidate operation No. 2 is an operation in which a hand or the like is held in the order of the mark 27 and the mark 26. When a hand is held over the mark 27, the hand is interposed between the mark 27 and the image pickup unit 90, and as shown in FIG. 10 (A), the mark 27 (the mark represented as the imaged object P27 in the captured image). (See FIG. 10B)) is not imaged by the imaging unit 90. Therefore, the mark 27 changes from the detected state to the non-detected state. Subsequently, when the hand is moved to the left and the hand is held over the mark 26, the hand is interposed between the mark 26 and the imaging unit 90. As a result, as shown in FIG. 10 (B), the mark 26 (the mark represented as the imaged object P26 in the captured image (see FIG. 10 (A))) is not imaged by the imaging unit 90. Therefore, the mark 26 changes from the detected state to the non-detected state. In this example, the mark 27 corresponds to the "first mark" of the present invention, and the mark 26 corresponds to the "second mark" of the present invention. Further, the mode specified by the specific information of the candidate operation No. 2 (second candidate operation) is "a marker group in the order from the other side (right side) of the predetermined direction (direction in which the marks 21 to 27 are lined up) to one side (left side). It corresponds to "the detection state of each of the marks 26 and 27 of 20 changes (second operation)". In this example, when a predetermined time (for example, 1 second) has not elapsed from the time when the non-detection state of the mark 27 is detected to the time when the non-detection state of the mark 26 is detected, "mark 27, mark 26". The condition of "changing from the detected state to the non-detected state in the order of" may be satisfied.

As shown in FIG. 8, the candidate operation No. 3 is an operation in which a hand or the like is held in the order of the mark 25 → 26 → 25 → 26. When a hand is held over the mark 25, the hand is interposed between the mark 25 and the image pickup unit 90, and the mark 25 is not imaged by the image pickup unit 90. Therefore, the mark 25 changes from the detected state to the non-detected state. Subsequently, when the hand is moved to the right and the hand is held over the mark 26, the hand is interposed between the mark 26 and the imaging unit 90. As a result, the mark 26 is not imaged by the imaging unit 90. Therefore, the mark 26 changes from the detected state to the non-detected state. Subsequently, the same operation (the operation in which the hand is held in the order of the mark 25 and the mark 26) is repeatedly performed, and the state changes from the detected state to the non-detected state in the order of the mark 25 and the mark 26. In this example, the mark for which the non-detection state is detected first corresponds to the "first mark" of the present invention, and the mark for which the non-detection state is detected later corresponds to the "second mark" of the present invention. .. In this example, when the time interval of the detection timing of the non-detection state that is sequentially detected between different marks is within a predetermined time (for example, 1 second), the order is "mark 25-> 26-> 25-> 26". It is assumed that the condition of "changing from the detected state to the non-detected state" is satisfied.

As shown in FIG. 8, the candidate operation No. 4 is an operation in which a hand or the like is held in the order of the mark 22 → 23 → ... 26 → 22 → 23 → ... 26. When a hand is held over the mark 22, the hand is interposed between the mark 22 and the image pickup unit 90, and the mark 22 is not imaged by the image pickup unit 90. Therefore, the mark 22 changes from the detected state to the non-detected state. Subsequently, when the hand is moved to the right and the hand is held in the order of the mark 23, the mark 24, the mark 25, and the mark 26, the mark 23, the mark 24, the mark 25, and the mark 26 are changed from the detected state to the non-detected state in this order. It changes with. Subsequently, the same operation (mark 22, mark 23, mark 24, mark 25, mark 26) is repeatedly performed, and the mark 22, the mark 23, the mark 24, the mark 25, and the mark 26 are changed from the detected state to the non-detected state in this order. Change. In this example, the mark for which the non-detection state is detected first corresponds to the "first mark" of the present invention, and the mark for which the non-detection state is detected later corresponds to the "second mark" of the present invention. .. In this example, when the time interval of the detection timing of the non-detection state that is sequentially detected between different marks is within a predetermined time (for example, 1 second), "mark 21 → 22 → ... 27 →" It is assumed that the condition of "changing from the detected state to the non-detected state in the order of 21 → 22 → ... 27" is satisfied.

When the control circuit 10 determines in step S14 that the motion of the moving body detected in step S13 is not a candidate motion, the process proceeds to No and the process of step S12 is performed again. On the other hand, when the control circuit 10 determines in step S14 that the motion of the moving body detected in step S13 is a candidate motion, the process proceeds to Yes and the process of step S15 is performed.

The control circuit 10 executes a control command in step S15. That is, the control circuit 10 executes the control command corresponding to the candidate operation detected in step S14. As shown in FIG. 8, a control command is associated with each candidate operation and stored in the ROM 10B. For example, the ROM 10B is associated with a candidate operation of "holding a hand or the like in the order of the mark 21 and the mark 22", and a control command of "increasing the thermal power level of the gas burner from" 1 "to" 2 "" (No. 1). 1 command) is stored. The gas burner for increasing the thermal power by this command is, for example, a gas burner for which the ignition operation or the thermal power adjustment was performed immediately before. The ROM 10B is associated with the candidate operation of "holding a hand or the like in the order of the mark 27 and the mark 26", and is associated with a control command (second command) of "reducing the thermal power level of the gas burner from" 7 "to" 6 "". ) Is remembered. The gas burner for increasing the thermal power by this command is, for example, a gas burner for which the ignition operation or the thermal power adjustment was performed immediately before. Further, the ROM 10B stores a control command of "extinguishing the gas burner 51" in association with a candidate operation of "holding a hand or the like in the order of the mark 25, the mark 26, the mark 25, and the mark 26". Further, the ROM 10B stores a control command of "menu setting" in association with a candidate operation of "mark 22, mark 23 ... mark 26, mark 22, mark 23 ... mark 26, etc. are held in this order". ing. For example, when the menu setting is started, operations such as setting the cooking mode (switching between the automatic cooking mode and the normal mode) and setting the temperature of the gas burner 54 (grill burner) become possible. Specifically, when the control command of "menu setting" is executed, the automatic cooking mode is started by setting a predetermined state (for example, the mark 21 is in the non-detection state). When the process of step S15 is completed, the control circuit 10 performs step S11 again.

In addition to the control commands shown in FIG. 8, various control commands are stored in the ROM 10B in association with candidate operations. For example, the ROM 10B stores a control command in which the adjustment amount (change amount) of the thermal power of the gas burner is determined based on the type of gesture pattern (displacement amount of the moving body) by the hand to be imaged. That is, in the ROM 10B, the adjustment amount (change amount) of the thermal power of the gas burner is determined according to the number of marks in the non-detection state (state in which a hand or the like is held) and the order of the marks in the non-detection state. .. For example, when a hand or the like is held in order from the mark 21 in a predetermined direction (direction in which the marks 21 to 27 are lined up) to any one of the marks 22 to 27 toward the right, the hand or the like is finally held according to the mark. It is designed to adjust the firepower of the gas burner. Specifically, the ROM 10B is associated with the candidate operation (first candidate operation) that "the detection state changes in the order of the mark 21, the mark 22 ... the mark 24 (first operation)" in addition to the candidate operation No1. Then, a control command (first command) such as "increase the thermal power level of the gas burner to" 4 "" is stored. Similarly, when a hand or the like is held in order from the mark 27 in a predetermined direction (the direction in which the marks 21 to 27 are lined up) to any one of the marks 21 to 26 toward the left, the hand or the like is finally held according to the mark. It is designed to adjust the thermal power of the gas burner. Specifically, the ROM 10B is associated with the candidate operation (second candidate operation) that "the detection state changes in the order of the mark 27, the mark 26 ... the mark 24 (second operation)" in addition to the candidate operation No2. Then, a control command (second command) such as "reduce the thermal power level of the gas burner to" 4 "" is stored.

For example, the ROM 10B stores a control command of "extinguishing the gas burner 52" in association with a candidate operation of "holding a hand or the like in the order of the mark 22, the mark 23, the mark 22, and the mark 23". Similarly, the ROM 10B stores a control command of "extinguishing the gas burner 53" in association with a candidate operation of "holding a hand or the like in the order of the mark 23, the mark 24, the mark 23, and the mark 24".

1-4. Effect of this configuration In the above system Sy, the control circuit 10 can detect the user's operation performed within a predetermined range (within the range imaged by the imaging unit 90) as the operation of a moving object. Then, when the motion of the moving object detected by the control circuit 10 is a candidate motion stored in the ROM 10B, the control circuit 10 executes a control command associated with the candidate motion. Therefore, the user causes the image pickup unit 90 to image the movement on the top plate 5 so that the predetermined candidate movement can be detected without manually touching the gas stove 1. Can be made to perform the desired control.

In the above system Sy, when the detection states of the plurality of marks 21 to 27 by the control circuit 10 change based on the user's operation on the top plate 5, the change of the detection states of the plurality of marks 21 to 27 is moved. Can be detected as the operation of. Therefore, the system can be realized with a simple configuration in which a plurality of marks 21 to 27 are provided on the gas stove 1.

When trying to detect the movement of an imaged object by analyzing the captured image, the amount of processing during image analysis becomes relatively large. However, the system Sy can detect the movement of a moving object by detecting a change in the detection state of a plurality of marks 21 to 27, requires a relatively small amount of processing during image analysis, and is a candidate more quickly. It is possible to determine whether or not it is an operation.

In the above system Sy, the state changed from a state in which a hand or the like was held over the first mark (for example, the mark 21) to a state in which the hand or the like was held over the second mark (for example, the mark 22) within a predetermined time. In the case, "the detection state of the second mark (for example, the mark 22) has changed after the detection state of the first mark (for example, the mark 21) has changed, and before the predetermined time has elapsed." Therefore, the movement of a moving object such as a hand can be easily detected based on the change in the detection state of the two marks. Further, after the detection state of the first mark (for example, the mark 21) has changed, it is determined whether or not the detection state of the second mark (for example, the mark 22) has changed before the predetermined time elapses. be. Therefore, the detection time of the movement of the moving body can be limited to a predetermined time, and it is possible to quickly determine whether or not the movement of the hand or the like has been performed.

In the above system Sy, the control circuit 10 moves a hand or the like along a predetermined direction (arrangement directions of a plurality of marks 21 to 27) on the mark group 20 to move each mark of the mark group 20 in the order along the predetermined direction. The detection states of 21 to 27 change. Then, it is detected as the first operation that the detection states of the marks 21 to 27 of the mark group 20 have changed in the order from one side to the other side in the predetermined direction, and the marks are marked in the order from the other side to the other side in the predetermined direction. The change in the detection state of each mark 21 to 27 in the group 20 is detected as the second operation. The control circuit 10 executes the first command (command to increase the thermal power of the stove units 4A, 4B, 4C) when the first operation is the first candidate operation stored in the ROM 10B. Further, the control circuit 10 executes a second command (a command for reducing the thermal power of the stove units 4A, 4B, 4C) when the second operation is the second candidate operation stored in the ROM 10B. Therefore, the user's operation of the image of sliding the operation unit such as the thermal power adjustment lever can be detected as the first operation or the second operation, and the stove units 4A, 4B, based on the intuitive user's operation, The firepower of 4C can be adjusted.

<Second Embodiment>
2-1. Outline of Gas Stove System The system Sy of the second embodiment will be described with reference to FIG. The system Sy of the second embodiment is different from the first embodiment in that the mark group 20 is not provided, and other configurations and the like are the same as those of the first embodiment. Therefore, the same configuration of the first embodiment will be described using the same reference numerals, and detailed description thereof will be omitted.

The command execution control of the system Sy of the second embodiment is different from that of the first embodiment in step S13 (method of detecting the motion of a moving body) in FIG. In the second embodiment, the control circuit 10 detects a moving object in each captured image based on a plurality of captured images captured at a plurality of different times. As a method for detecting a moving object from a plurality of images, a known method can be used. For example, when the position of a region containing a certain number of pixels whose color information (each numerical value of the three elements of color (RGB)) is a value in a certain range is changed among a plurality of captured images. The area composed of these pixels can be used as a moving object. Further, for example, when a feature point is detected between a plurality of captured images and the position of the feature point is changed, the feature point can be used as a moving object.

The candidate motion identification information used in step S14 of FIG. 7 is information for identifying the detection position of a moving object in the captured image. Then, for example, as the specific information corresponding to the candidate operation No. 1, instead of the information for specifying the non-detection state of the mark 21, the hand H (moving body) is placed on the left front end portion of the top plate 5 as shown in FIG. 11 (A). Adopt information that identifies the state in which it is held over. Further, for example, instead of the information for identifying the non-detection state of the mark 22, the hand H (moving body) is held slightly to the right of the left front end portion of the top plate 5 as shown in FIG. 11 (B). Adopt information that identifies the condition. Similarly, instead of the information that identifies the non-detection state of the marks 23 to 27, the hand H (moving object) is placed at the position corresponding to the marks 23 to 27 (the position where the marks 23 to 27 are omitted with respect to the first embodiment). ) Adopts information that identifies the state in which it is held over.

<Third Embodiment>
3-1. Outline of Gas Stove System The system Sy of the third embodiment will be described with reference to FIG. The system Sy of the third embodiment is different from the first embodiment in the arrangement mode of the mark group, and the other configurations and the like are the same as those of the first embodiment. Therefore, the same configuration of the first embodiment will be described using the same reference numerals, but detailed description thereof will be omitted.

As shown in FIG. 12, the gas stove 1 is provided with marker groups 320, 420, 520. The marker groups 320, 420, and 520 correspond to the stove portions 4A, 4B, and 4C, and are provided so as to surround the stove portions 4A, 4B, and 4C, respectively. Specifically, the mark groups 320, 420, and 520 are arranged along the outer circumferences of the trivets 9A, 9B, and 9C, centering on the gas burners 51, 52, and 53 of the stove portions 4A, 4B, and 4C. ..

The candidate operation identification information regarding the right stove portion 4A can be, for example, information for specifying the mode of the detection state of a plurality of marks (for example, marks 321, 322, 323 shown in FIG. 12) included in the mark group 320. Further, the candidate operation identification information regarding the left stove portion 4B may be, for example, information for specifying the mode of the detection state of a plurality of marks (for example, marks 421, 422, 423 shown in FIG. 12) included in the mark group 420. can. Further, the candidate operation specific information regarding the small stove unit 4C may be, for example, information for specifying the mode of the detection state of a plurality of marks (for example, marks 521, 522, 523 shown in FIG. 12) included in the mark group 520. can.

<Other Embodiments>
The present disclosure is not limited to the embodiments described by the above description and drawings. For example, the features of the embodiments described above or below can be combined in any combination within a consistent range. Further, any of the features of the above-mentioned or later-described embodiments may be omitted unless it is clearly stated as essential. Further, the above-described embodiment may be modified as follows.

In the first embodiment, the imaging region imaged by the imaging unit 90 is a range including all of the stove units 4A, 4B, and 4C (see FIG. 6), but other ranges may be used. For example, the imaging region may be a range that includes the leading edge of the top plate 5 and its periphery. Alternatively, the range may be such that only a part of the stove portions 4A, 4B, and 4C is included.

In the first embodiment, when the start condition of the command execution control shown in FIG. 7 is satisfied, the time when the power of the system Sy is switched to the ON state and the time when the gas burners 51, 52, and 53 are ignited are shown. However, it may be at other timings. For example, when the start condition of the command execution control is satisfied, it may be the time when the operation unit 83 is operated to start the command execution control.

In the first embodiment, as the gas burner whose command is controlled based on the candidate operations Nos. 1 and 2, the gas burner for which the ignition operation or the thermal power adjustment has been performed immediately before is designated, but other designation methods may be adopted. good. For example, the gas burner whose command is controlled based on the candidate operations Nos. 1 and 2 may be predetermined by setting. That is, only the gas burner 51 may be command-controlled, or all of the gas burners 51, 52, and 53 may be command-controlled. Further, for example, the command-controlled gas burner may be determined based on the captured image. That is, in the captured image captured after the candidate operation is executed, the hand is held over the cooking container, and the gas burner on which the cooking container is placed may be command-controlled. Further, for example, after executing the candidate operation, the gas burner corresponding to the mark may be command-controlled by holding a hand over a predetermined mark to put it in the non-detection state.

In the first embodiment, the control command "increase the thermal power level of the gas burner from" 1 "to" 2 "" is adopted as the first command corresponding to the candidate operation No. 1, but the thermal power is increased in other modes. You may let me. For example, control may be performed to raise the level by one level from the thermal power level before the thermal power increase.

In the first embodiment, as a candidate operation corresponding to a control command for reducing the thermal power of the gas burner, an operation of moving a hand from the right side to the left side with respect to the gas stove 1 (candidate operation No. 2) is exemplified. However, even when the thermal power of the gas burner is reduced, the operation of moving the hand from the left side to the right side of the gas stove 1 may be performed as in the candidate operation No. 1. For example, when the firepower level of the gas burner is "3", the firepower level is reduced from "3" to "2" by performing the candidate action of "holding a hand or the like in the order of the mark 21 and the mark 22". May be configured.

In the first embodiment, as a candidate operation corresponding to the control command for increasing the thermal power of the gas burner, an operation of moving the hand from the left side to the right side with respect to the gas stove 1 (candidate operation No. 1) is exemplified. However, the configuration may be such that a control command for increasing the thermal power of the gas burner is executed by another candidate operation. For example, the thermal power of the gas burner may be increased to the thermal power level corresponding to the predetermined mark by setting the predetermined mark in the non-detection state for a predetermined time (for example, 3 seconds).

In the above embodiment, the "predetermined direction" is a linear direction, and it is detected as the first operation that the detection state of each mark of the mark group changes in the order from one side to the other side of the predetermined direction, and the other side. It was detected as the second operation that the detection state of each mark in the mark group changed in the order from to one side. However, it is not limited to this example. For example, the predetermined direction may be a direction along a curved virtual curve, or may be a circumferential direction of a circle or an ellipse. In this case, the plurality of marks may be arranged along a curved virtual curve, or may be arranged along a virtual circle or a virtual ellipse.

In the first and third embodiments, different arrangement configurations of the mark groups are illustrated. However, the number and arrangement layout of the marks constituting the mark group are not limited to these. For example, the number of marks constituting the mark group 20 of the first embodiment may be other than seven.

In the first and third embodiments, the examples in which the marks 21 to 27 are configured as LEDs are shown. However, the marks 21 to 27 may be a light emitting part other than the LED, and may not be a light emitting part. Further, as the shape of the marks 21 to 27, various shapes such as a figure (a figure such as a circle, a triangle, a square, and a star), a pattern, and a symbol can be adopted.
