The electric power of the battery 101 is supplied to the functional blocks 121 to 123 of the data processing unit 120 via the DC / DC converter unit 110.
The DC / DC converter unit 110 is a DC / DC (Direct Current / Direct Current) converter that converts the output voltage of the battery 101 into supply voltages VDD1 to VDD3 for the functional blocks 121 to 123 of the data processing unit 120.

Individual DC /

DC converters

111, 113, 115 corresponding to each functional block 121 to 123 are provided in the DC / DC converter unit 110, and a process of converting the supply voltage to the supply voltage VDD1 to VDD3 for each functional block is performed. ing.
Further, each of the DC /

DC converters

111, 113, 115 is provided with individual

current detection units

112, 114, 116, and each functional block 121 is provided via the DC /

DC converters

111, 113, 115. The amount of supply current for ~ 123 is detected.

The functional blocks 121 to 123 of the data processing unit 120 are processing circuits that individually execute various functions executed by the image pickup apparatus 100. The image pickup apparatus 100 includes, for example, image capturing processing, signal processing of captured images, recording processing of images after signal processing in a storage unit, reading of images stored in the storage unit and display processing for the display unit, AF, AE.

Although only three functional blocks are shown in FIG. 1, the number of blocks is an example, and various configurations such as a configuration having only two functional blocks and a configuration having 10 or more functional blocks are available. It is possible.

As shown in FIG. 1, each of the functional blocks 121 to 123 is provided with temperature detection units 131 to 133.
These detect the temperature of each functional block 121-123. In the operating state, each of the functional blocks 121 to 123 generates heat because a current flows through the electric circuit in the block, and the temperature changes.
The temperature detection units 131 to 133 observe this temperature change in units of functional blocks.

The temperature information for each functional block detected by the temperature detection units 131 to 133 is input to the device state transition control unit 142 via the temperature detection unit 141 of the data processing unit 120.

DC converters

DC converters

111, 113, 115 corresponding to each functional block is executed, stop control, output level (voltage) change control, and the like are performed.

That is, it may be configured to record the usage mode corresponding to the user.
By inputting user information (user ID) when using the image pickup apparatus 100, it is possible to record usage history and usage mode information corresponding to each user.

By recording the user-corresponding usage mode in the information storage unit 144 in this way, the device state transition control unit 142 of the data processing unit 120 is based on the user-corresponding usage mode information recorded in the information storage unit 144. It is possible to perform user-specific control.

For example, in the case of a user who rarely uses the display unit, it is possible to set a mode that reduces the power consumption of the display unit. For users who have a long shooting time or who have a large number of shots, it is possible to display the remaining number of shots as soon as possible.

FIG. 2 shows the details of the input signal for the power calculation unit 145.
The current values (analog signals) detected by the

current detection units

112, 114, 116 corresponding to each functional block in the DC / DC converter unit 110 are converted into digital values by the A / D converter, and further, each of them is performed by the multiplexer 117. Sequential data of the current value detected by the current detection unit is generated and input to the power calculation unit 145.

The data input to the power calculation unit 145 is column data of the current value supplied to each functional block. For example

functional blocks

The real-time power consumption (power) of each functional block is calculated by using the input voltage values (VDD1 to 3) of the functional blocks.
The power information for each functional block calculated by the power calculation unit 145 is input to the device state transition control unit 142.

In addition to the power information for each functional block, the device state transition control unit 142 receives information input from each component of the temperature detection unit 141, the number of possible shots / remaining usage time calculation unit 143, and the battery level detection unit 146. Based on this, the optimum state of the imaging device is determined, and the state transition to the optimum state is performed. For this transition process, the device state transition control unit 142 outputs a state transition instruction signal to each function block 121 to 123.

The device state transition control unit 142 inputs the remaining amount information of the battery 101 from the battery remaining amount detecting unit 146, and determines whether or not the input remaining battery value is smaller than the predetermined value.

If the remaining battery level is not smaller than the specified value, the process returns to step S101 and the process of step S101 or less is repeated.
On the other hand, if the remaining battery level is smaller than the specified value, the process proceeds to step S112.
In step S112, the device state transition control unit 142 executes the power reduction process. The power reduction process in this case is executed not as a process according to the user instruction but as a process for optimizing the operation mode.

This determination process is executed for each functional block.

If it is determined in step S142 that there is no functional block in which the abnormal current is detected, the abnormal current detection process of step S141 is continuously executed.
On the other hand, if at least one functional block in which the abnormal current is detected is detected in step S142, the process proceeds to step S143.

When even one functional block in which the abnormal current is detected is detected, the functional state transition control unit 142 displays a device abnormality detection message on the display unit in step S143.

Further, these pieces of information are recorded in the information storage unit 144.

Further, the image pickup apparatus 100 may be configured to execute communication with the server via the communication unit, transmit the acquired information (a) to (d) to the server, and store the acquired information (a) to (d) in the storage unit in the server.
For example, the imaging device 100 transmits time-series device status information corresponding to the user to the server and stores it in a storage unit in the server.

By this process, the server can accumulate usage mode information of many users.
Based on this accumulated information, the server generates a new device operation transition method that suits the usage of many users, and as the operation of the next model to be developed, the operation transition method that is more suitable for the user's usage than before.

For the correction of the abnormal current determination value, a correction allowable system and a correction non-allowable system may be provided for each power supply system.

As it grows larger, there are concerns about safety. In order to eliminate such concerns, a power supply system (functional block) that does not correct the abnormal current determination value may be provided.

(9) Battery level: Battery level at the timing of saving load current information and power consumption information.

All or a combination of multiple items of this information is stored in the information storage unit 144, and by analyzing the stored data, the optimum device operation transition method, the optimum abnormal current value set value, etc. are analyzed and executed. Becomes possible.
