FIG. 1 is a block diagram of an information recording / reproducing apparatus and a camera section of an embodiment. The basic configuration is the same as that shown in FIG. 5 described in the conventional example.

A block on the left side surrounded by a broken line in the figure shows the inside of the main body of the information recording / reproducing apparatus corresponding to 1 in FIG. Similarly, the block on the right side corresponds to the camera unit of 7.

Reference numeral 100 is a display block, 101 is a display memory, 102 is a system memory for controlling the information recording / reproducing apparatus main body, 103 is a power supply selection switching means, and 104 is the information recording / reproducing apparatus main body.

The operation of the embodiment having the above configuration will be described with reference to the flowchart of FIG.

In step S1, the system of the main body is initialized. Then, in S2, it is checked whether or not the system restriction condition is satisfied, for example, here, it is necessary to charge the strobe. That is, the brightness of the subject is measured by a photometric means (not shown), and if it is darker than a predetermined amount, the strobe is set to the light emission mode. Then, if the charge amount is insufficient, for example, by measuring the voltage of the main capacitor of the strobe, the process proceeds to S3 to satisfy the charge condition. If the charging is not insufficient, the process proceeds to S4, the normal operation without system limitation is performed, and the process proceeds to S5.

At S3, the system is restricted. For example,
Turn off the display backlight. That is, the microprocessor 104 of FIG. 1 selects the power supply selection circuit,
The supply to the display device 100 is stopped. And strobe 2
09 is charged. After charging to a predetermined amount, a strobe unit (not shown) automatically stops charging.

In step S5, it is checked whether or not a system termination condition, for example, a power OFF switch has been pressed or an auto-shutdown timer has timed out. If it occurs, stop the main operation to stop the whole system. If it has not occurred, the process returns to S2 and the above operation is repeated.

The above operation is performed by the OS of the information recording / reproducing apparatus main body.
It is configured as (OPERATION SYSTEM).

(Other Embodiments) In the above-mentioned embodiment, an example in which the system limiting condition is limited to the item whether or not the strobe needs to be charged has been described in order to simplify the description. Now, the contents of the limitation of the system will be explained with respect to a configuration in which the backlight of the display device is turned off. However, in actual application, a system in which items and contents are added or changed is possible.

First, the system limiting conditions will be described in detail. As a condition item, condition item A Is the camera unit connected?

Condition item B Is the battery level of the main body less than or equal to a predetermined amount?

Condition item C Shooting standby switch is O
N?

Condition item D Shooting trigger switch is ON
Or?

Condition Item E Is it necessary to charge the strobe?

Condition item F Is power supplied to the main body from outside?

And the like.

Here, the connection of the camera section of the condition item A can be easily determined by using the configuration shown in FIG. In addition,
The reference numerals 104, 108, and 200 shown in FIG. 3 correspond to the same numbers shown in FIG.

FIG. 3A shows a state in which the camera section is not connected. The PORT-A of the CPU 104 becomes high level.

FIG. 3B shows a state in which the camera section is connected. The PORT-A of the CPU 104 becomes low level.

FIG. 4 is a flowchart showing a part of the operation of the embodiment in which the present invention is carried out under the condition item A. Figure 4
Replaces the system limiting condition determining step of step S2 of FIG. 2, and will be described with reference to FIGS. 2 and 4.

In step S200, the level of PORT-A is checked. If the level is high, it is determined that no connection has been made and the process proceeds to step S201. If it is at a low level, it is determined that the connection is established and the process proceeds to S202.

In step S201, the storage of the state of being mounted, which is temporarily stored in the storage unit in the main body system, is cleared. Then, in S203, it is checked whether or not the detachment state is already stored in the storage unit in the main body system, and if so, the process proceeds to S4 in FIG. S2 if not stored
Go to 05. In S205, the fact that the vehicle is in the separated state is newly stored, and the process proceeds to S3 in FIG.

In S202, the memory of the disengaged state, which is temporarily stored in the storage unit in the main body system, is cleared. Then, in S204, it is checked whether or not the mounting state is already stored in the storage unit in the main body system, and if so, the process proceeds to S4 in FIG. S if not remembered
Proceed to 206. In S206, the fact that the device is newly mounted is stored, and the process proceeds to S3 in FIG.

As for the condition item B, the information recording / reproducing apparatus main body may measure the battery voltage or the internal resistance of the battery of the camera section, or the CPU in the camera section may measure it and transmit it to the main body by communication.

Since other condition items can be easily realized by a known method, detailed description will be omitted.

Of the items shown above, for example, only item A above may be used as the condition item. In this case, since the judgment is simple, the system of the information recording / reproducing apparatus main body can be easily controlled.

Alternatively, a plurality of AND conditions such as A & B may be used. In this case, since the power source is not carelessly limited, there is also an effect that the operability is less deteriorated. Further, an OR condition may be added as in A & (B or E).

These may be determined according to the power consumption characteristics of the camera section and the power supply capacity from the information recording / reproducing apparatus main body. That is, it depends on how far the information recording / reproducing apparatus main body can supply operation power during the operation of the camera. For example,
If the strobe cannot be charged but other operations and shooting can be sufficiently performed, the condition is only E. And when the battery level is low, the ambient temperature is low, etc.
If the battery performance is not sufficient, change the condition items. As described above, the types and combinations of items can be configured to correspond to various cases.

Similarly, the details of the system limitation will be described below. As the system limitation item, the limitation item a
Turn off at least a part of the power supply of the information recording / reproducing apparatus main body.

Restriction item b The operating frequency of at least part of the information recording / reproducing apparatus main body is restricted.

Restriction item c The weight of the execution of a part of the tasks of the information recording / reproducing apparatus main body is restricted, for example, background processing is stopped. Lower the specific gravity.

And the like.

The restricted item a is to turn off the power of a function which is not used at that time among the plurality of functions of the main body, and has an advantage of not affecting other functions.

The restriction item b has the advantage that even if the response to the display or operation of the main body is slightly delayed, it is possible to take a picture without degrading the performance of the camera.

The limiting item c is, for example, when the main body has a communication function, and when the load of the CPU for communication is not so heavy, the weight of the processing for communication is lowered,
There is an advantage that shooting can be performed without deteriorating the display and other operation performance.

Then, like the above condition item, only the above item, for example, a may be restricted. Alternatively, a
It is also possible to limit a plurality of ANDs such as & b. further,
An OR condition may be added as in a & (b or c). As described above, various types and combinations of items can be configured.

Furthermore, it is also possible to set a level as a condition, apply a limit according to the level, or change the content of the limit.

For example, the above condition items A, B, C, D, E
To set condition level 1 A condition level 2 A & B condition level 3 A & B & C condition level 4 A & C condition level 5 A & B & D condition level 6 A & B & E. Then, in the case of level 1, it is possible to configure restriction items c In the case of level 2 or 4, restriction items a In the case of levels 3 or 5, 6 Restriction items a and c.

These restriction items and condition levels can be appropriately determined by the power consumption characteristics of the camera unit and the power supply capability from the information recording / reproducing apparatus main body, like the above condition items.

As described above, it is needless to say that the condition item, the type of the restriction item, and the combination can be variously configured in addition to the embodiment.

As described above, according to the present invention,
Even when shooting with the camera when the main unit is driven by batteries, sufficient power can be supplied from the main unit, and the main unit and camera can operate stably without the power supply voltage dropping at the moment of shooting. Is.
