Detailed Description
For the purpose of illustrating the technical features of the present invention in detail, the following examples are given and are illustrated in the accompanying drawings.
As shown in fig. 1, the control method provided in the embodiment is applied to a mobile phone 10 (e.g. a smart phone), and the mobile phone 10 includes an operation processing unit 12, and a camera module 13, a flash 14 and a memory 15 electrically connected to the operation processing unit 12. The arithmetic processing unit 12 is in the embodiment a processor of the handset 10. The camera module 13 may be turned on or off under the control of the arithmetic processing unit 12, and the camera module 13 may perform a photographing function when turned on. The flash 14 is disposed adjacent to the camera module 13 (not shown), the flash 14 may also be turned on or off under the control of the arithmetic processing unit 12, and the flash 14 may perform a flash mode (flash mode) or a torch mode (torch mode) when turned on. In the flash mode, the flash 14 will emit light instantaneously, once or at intervals, and in the flashlight mode, the flash 14 will emit light continuously. The memory 15 stores a comparison table (as shown in fig. 3), wherein the contents of the comparison table relate to a set of case temperatures T (i.e., T1, T2, T3, … …), and a set of off times t_off (i.e., A1, A2, A3, … …) and a set of cooling time t_cool (i.e., B1, B2, B3, … …) corresponding to the case temperatures T, which are temperatures of the case 11 of the mobile phone 10.
The control method provided in the embodiment includes the following steps, please refer to fig. 2A and fig. 2B.
Step S1: starting. The handset 10 is turned on and in normal operation so that the camera module 13 can be turned on and the flashlight mode of the flashlight 14 can be turned on.
Step S2 is performed after step S1. In step S2, the user turns on an Application (APP) of the mobile phone 10, so that the mobile phone 10 is ready to turn on the flashlight mode of the camera module 13 and the flashlight 14. In step S2, both the camera module 13 and the flash 14 are not yet turned on.
Step S3 is performed after step S2. In step S3, the arithmetic processing unit 12 determines whether the flash 14 is in the off cooling state, and if so, proceeds to step S16, otherwise proceeds to step S4. In step S16, the arithmetic processing unit 12 prohibits the on-flashlight mode of the flashlight 14, and after step S16, the flow proceeds to step S17, and all steps are ended.
After step S3, step S4 is performed, and the arithmetic processing unit 12 monitors and reads the housing temperature T of the housing 11 of the mobile phone 10, and obtains a temperature monitor on the mobile phone system, thereby continuously monitoring and reading the housing temperature T. When the temperature monitor monitors that the housing temperature T is higher than the urgent temperature, the temperature monitor will send out the urgent temperature too high notification to the arithmetic processing unit 12. In this embodiment, the temperature T of the casing is monitored and read by the mobile phone system, and the temperature T of the casing may also be monitored by hardware (e.g. a temperature sensor).
Step S5 is performed after step S4. In step S5, the arithmetic processing unit 12 refers to the comparison table in the memory 15 according to the case temperature T obtained in step S4, and further obtains the off time t_off and the cooling-required time t_cool corresponding to the case temperature T from the comparison table.
Step S5 is followed by step S6 of turning on the flashlight mode of the flash 14, allowing the user to take a picture or photograph using the camera module 13 and the flash 14.
Step S7 is performed after step S6. In step S7, the arithmetic processing unit 12 calculates the use time of the flash 14, that is, the time when the flash 14 turns on the flashlight mode and maintains the flashlight mode.
Step S8 (see fig. 2B) is performed after step S7. In step S8, the arithmetic processing unit 12 compares the use time of the flash 14 with the off time t_off obtained in step S5, and proceeds to step S12 if the use time of the flash 14 reaches the off time t_off (i.e., the use time is equal to or longer than the off time t_off), and proceeds to step S9 if the use time does not reach the off time t_off (i.e., the use time is shorter than the off time t_off).
In step S9, the operation processing unit 12 determines whether an urgent temperature excessive notification sent by the temperature monitor is received, for example, when the user performs photographing, the user executes other application programs (APP) at the same time to cause the case temperature T of the mobile phone 10 to be higher than the urgent temperature, and since the temperature monitor continuously monitors the case temperature T of the mobile phone 10 from step S4, if the operation processing unit 12 determines that the case temperature T is higher than the urgent temperature, the temperature monitor sends an urgent temperature excessive notification to the operation processing unit 12. If the arithmetic processing unit 12 receives the emergency temperature excessive notification, the process proceeds to step S12 as well, otherwise, the process proceeds to step S10.
In step S10, the arithmetic processing unit 12 determines whether the user actively turns off the flashlight mode of the flashlight 14, if yes, it goes to step S11, and if no, it goes back to step S8.
Step S11: the arithmetic processing unit 12 turns off the flashlight mode of the flashlight 14, and then proceeds to step S17, ending all the steps.
As described in the previous paragraph, if the use time reaches the off time t_off in step S8 or the arithmetic processing unit 12 receives the urgent excessive temperature notification in step S9, step S12 is executed in both cases: the flash 14 is forcibly turned off, so that the mobile phone 10 enters a cooling mode and starts to cool, and the camera module 13 and the flash 14 are prevented from overheating.
Step S13 is performed after step S12. In step S13, the arithmetic processing unit 12 calculates a wait cooling time t_count, which is a time when the flash 14 turns off the flashlight mode and maintains the off state.
Step S14 is performed after step S13. In step S14, the arithmetic processing unit 12 compares the waiting cooling time t_count with the cooling-required time t_cool obtained in step S5, proceeds to step S15 if the waiting cooling time t_count reaches the cooling-required time t_cool (i.e., the waiting cooling time t_count is equal to or greater than the cooling-required time t_cool), and returns to step S13 if the waiting cooling time t_count does not reach the cooling-required time t_cool (i.e., the waiting cooling time t_count is less than the cooling-required time t_cool).
After step S14, the operation processing unit 12 proceeds to step S15 to deactivate the cooling mode, so as to allow the mobile phone 10 to subsequently be able to turn on the flashlight mode of the flashlight 14 again.
Step S17: and (5) ending.
By the control method of the present embodiment, when the user is in the flashlight mode using the flash 14, if the use time of the flash 14 reaches the off time t_off corresponding to the case temperature T, the flash 14 is forcibly turned off, so as to avoid overheating of the flash 14 and the camera module 13, thereby affecting the quality of the image output by the camera module 13, and even the camera module 13 fails.
Finally, it should be understood that the steps disclosed in the above embodiments are only illustrative, and are not intended to limit the scope of the present invention, and other easily conceivable steps are also included in the scope of the present invention.
