In the example of FIG. 4A, the electronic device 100 stops recording the video when the temperature information measured by the temperature measurement unit 110 becomes equal to or higher than a predetermined threshold value, which is the upper limit temperature Tmax. The system control unit 101 calculates the time (20 minutes) during which the temperature measured by the temperature measurement unit 110 is expected to reach the upper limit temperature Tmax as the operable time.

On the other hand, FIG. 4(b) exemplifies the temperature increase tendency when recording a moving image while the electronic device 100 is being cooled by the accessory device 200.

From among these, temperature rise data in FIG. 4(c), which is different from the temperature rise data in FIG. 4(a), is selected. FIG. 4C illustrates temperature rise data when recording a moving image while the electronic device 100 is being cooled by the accessory device 200. The operable time (40 minutes) according to the temperature increase data in FIG. 4(c) is longer than the operable time (20 minutes) according to the temperature increase data in FIG. 4(a). In this case, when video recording is performed while the electronic device 100 is being cooled by the accessory device 200, as shown in FIG. can be approximated. As a result, it is possible to appropriately calculate the operable time and notify the user.

Note that the temperature rise data stored in the storage unit 107 may be updated by calculating the difference between the temperature during video recording and the temperature rise data, and correcting the selected temperature rise data based on the difference. By doing so, it becomes possible to calculate the operable time with higher precision and notify the user when recording a moving image from next time onwards.

Furthermore, the method of notifying the available operating time is not limited to displaying the time using characters or symbols, but may also display the percentage of the total time using a progress bar, a graph, or the like.

Appropriate temperature rise data is selected from the list and transmitted to the electronic device 100.

Thereby, as shown in FIG. 4(d), it is possible to approximate the temperature rise trend during video recording and the temperature rise data for calculating the operable time. As a result, it is possible to appropriately calculate the operable time and notify the user.

Note that the temperature rise data stored in the storage unit 107 may be updated by calculating the difference between the temperature during video recording and the temperature rise data, and correcting the temperature rise data currently in use based on the difference. Further, the corrected temperature rise data may be transmitted to the accessory device 500 to update the temperature rise data stored in the storage unit 501. By doing so, it becomes possible to calculate the operable time with higher precision and notify the user when recording a moving image from next time onwards.

Furthermore, the method of notifying the available operating time is not limited to displaying the time using characters or symbols, but may also display the percentage of the total time using a progress bar, a graph, or the like.

[Embodiment 4]
Next, a fourth embodiment will be described with reference to FIGS. 9 to 11.

In the first to third embodiments, the electronic device 100 and the accessory devices 200 and 500 were configured separately. On the other hand, in the fourth embodiment, an electronic device 900 has a cooling unit 901, and an appropriate temperature increase is selected from a plurality of temperature increase data stored in a storage unit 107 based on the operating state of the cooling unit 901. This is an example of selecting data.

The configuration of an electronic device 900 according to the fourth embodiment includes a cooling section 901 and a cooling control section 902 in addition to the configuration shown in FIG. The configuration and function of the cooling unit 901 and the cooling control unit 902 are similar to the cooling unit 202 and the cooling control unit 203 of the accessory device 200 in FIG. 1 of the first embodiment.

The storage unit 107 stores a temperature rise data table shown in FIG. FIG. 11 is a diagram illustrating a temperature rise data table stored in the storage unit 107 of the electronic device 900. The temperature rise data table 1100 includes data 21 to 26 depending on the operating state of the cooling unit 901 for each video recording mode. The operating states of the cooling unit 901 include a stopped state and operating states with different cooling capacities, such as a cooling state 1 in which cooling is performed with strong power and a cooling state 2 in which cooling is performed with weak power.

FIG. 10 is a flowchart showing control processing of the electronic device 900 according to the fourth embodiment.

The processing in steps S1001 and S1002 in FIG. 10 is similar to the processing in steps S201 and S202 in FIG. 2(a).

In step S1003, the system control unit 101 determines whether or not the cooling unit 901 is to be operated. If the system control unit 101 determines to operate the cooling unit 901, the process proceeds to step S1004, and if it determines not to operate the cooling unit 901, the process proceeds to step S1005.

In step S1004, the system control unit 101 controls the cooling control unit 902 to start driving the cooling unit 901.

In step S1005, the system control unit 101 controls the cooling control unit 902 to stop driving the cooling unit 901.

In step S1006, the system control unit 101 selects appropriate temperature rise data from among the plurality of temperature rise data stored in the storage unit 107 based on the operating state of the cooling unit 901. When the cooling unit 901 is in operation, the system control unit 101 selects cooling state 1 data 23 from the temperature rise data table 1100 in FIG. , 24 or the data 25 and 26 of the cooling state 2 are selected. In addition, when the cooling unit 901 is stopped, the system control unit 101 selects data 21 or data from the temperature rise data table 1100 in FIG. 22 is selected.

In step S1007, the system control unit 101 calculates the operable time based on the temperature rise data selected in step S1006, and notifies the user via the display unit 109.

In the fourth embodiment, when recording a video while cooling the electronic device 900 with the cooling unit 901 as in FIG. 4(b), the electronic device is cooled with the cooling unit 901 stopped as in FIG. 4(a). Compared to the case where 900 performs video recording, the predicted time for the temperature measured by temperature measurement unit 110 to reach upper limit temperature Tmax is significantly different. In this case, if video recording is stopped after 20 minutes, for example, the user will not be able to obtain the cooling effect, and the user may feel uncomfortable about being able to use the device for a longer time than the notified operating time. There is sex.

Therefore, in the fourth embodiment, when recording a video while cooling the electronic device 900 by the cooling unit 901, based on the operating state of the cooling unit 901, the temperature rise data stored in the storage unit 107 is selected. Temperature rise data when recording a moving image in a state where the electronic device 900 similar to that shown in FIG. 4C is cooled by the cooling unit 901, which is different from the temperature rise data shown in FIG. 4A, is selected from the following. The operable time (40 minutes) according to the temperature increase data in FIG. 4(c) is longer than the operable time (20 minutes) according to the temperature increase data in FIG. 4(a). In this case, when video recording is performed while the electronic device 900 is cooled by the cooling unit 901, as shown in FIG. can be approximated. As a result, it is possible to appropriately calculate the operable time and notify the user.

Note that the temperature rise data stored in the storage unit 107 may be updated by calculating the difference between the temperature during video recording and the temperature rise data, and correcting the selected temperature rise data based on the difference. By doing so, it becomes possible to calculate the operable time with higher precision and notify the user when recording a moving image from next time onwards.

Furthermore, the method of notifying the available operating time is not limited to displaying the time using characters or symbols, but may also display the percentage of the total time using a progress bar, a graph, or the like.
