BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
[0010]
FIG. 1 is a block diagram showing an example of a camera remaining battery management device according to the present invention.
[0011]
In FIG. 1, reference numeral 1 denotes a battery, which supplies photographing power and display power to a camera.
[0012]
Reference numeral 2 denotes a battery checker for measuring the remaining battery level of the battery 1.
[0013]
Reference numeral 3 denotes a CPU, which has control means 11 for controlling the distribution of the remaining battery power by the remaining battery power distribution means 10 so that the power consumption for photographing and the power consumption for display can be secured.
[0014]
Reference numeral 4 denotes a memory in which average power consumption, power consumption during standby, and display power consumption required for one photographing operation are stored as data. The power consumption in the shooting mode is also stored as data. As the power consumption in the shooting mode, the power consumption is stored as data for each shooting mode.
[0015]
Reference numeral 5 denotes a setting unit for inputting information set by the user. The set information includes the number of images to be photographed, the time to display images, the photographing mode, and the like.
[0016]
Reference numeral 6 denotes a status display unit, which has a function of displaying a camera status such as a current shooting mode, the number of shootable images, and a displayable time.
[0017]
Reference numeral 7 denotes a flash unit that enables flash shooting, 8 denotes a shooting unit that adjusts shooting conditions such as telephoto and focus, and 9 denotes an image display unit that displays a shooting target for shooting.
[0018]
In a preferred first aspect of the present invention, the battery remaining amount of the battery 1 measured by the battery checker 3 by the battery remaining amount distributing means 10 is displayed as “for photographing” from a predetermined number of photographing power and a predetermined time display power. The control means 11 performs control so that the display battery remaining amount and the photographing battery remaining amount distributed by the battery remaining amount distribution means 10 cannot be shared with each other.
[0019]
In order for the battery remaining amount distributing means 10 to pre-allocate the remaining battery amount of the battery 1 for shooting and display, the remaining battery amount of one battery 1 may be allocated in advance for shooting and display, or The two batteries may be used for photography and display in advance. A capacitor or the like can be used to pre-allocate the remaining battery power of one battery 1 for shooting and display.
[0020]
In order for the control means 11 not to share the distributed remaining amount of the display battery and the remaining amount of the photographing battery with each other, a circuit control or the like may be used.
[0021]
According to the present invention, by distributing the display battery remaining amount and the photographing battery remaining amount which are distributed in this way, it is possible to secure the number of recordable images or the display time required by the user.
[0022]
A second preferred embodiment of the present invention will be described with reference to FIGS.
[0023]
After the remaining battery level of the battery 1 is allocated in advance for display and photographing by the remaining battery level distribution means 10, the processing of FIG. 2 is performed.
[0024]
First, a battery check is performed with a battery checker (S1). Next, arithmetic processing 1 is performed (S2). In arithmetic processing 1, the remaining battery level distribution means performs a process of pre-allocating the remaining battery level of the battery for shooting and display.
[0025]
Next, the maximum number of recordable images and the maximum image display time are displayed on the status display section 6 (S3).
[0026]
Next, it is determined whether or not the number of images is set by the setting unit 5 (S4). If it is determined that the number of images is to be set, the number of images is set (S5), and arithmetic processing 2 is performed (S6).
[0027]
The arithmetic processing 2 calculates the power consumption for photographing from the product of the average power consumption required for one photographing and the number of photographed images stored in the memory.
[0028]
For example, assuming that the average power consumption required for one shooting is a milliwatt / time and the number of shots is 20, the shooting power consumption is a × 20.
[0029]
Then, the distribution by the battery remaining amount distribution means is controlled so that the calculated power can be secured as the maximum power consumption for photographing. Such control is performed by the CPU.
[0030]
Next, the number of shootable images (the number of flashes) is displayed on the status display section (S8). Next, the image display time is displayed (S9).
[0031]
A third preferred embodiment of the present invention will be described with reference to FIGS.
[0032]
As shown in FIGS. 2 and 4, after the setting unit determines whether or not to set the number of images to be taken (S4), if it is determined not to set the number of images to be taken, the image display time is set (step S4). S7).
[0033]
Next, arithmetic processing 2 is performed (S8). In arithmetic processing 2, display power consumption is calculated from the product of display power consumption per unit time and display time stored in the memory.
[0034]
For example, if the display power consumption per unit time is b milliwatts / second and the display time is 2 seconds, the display power consumption is b × 2.
[0035]
Then, the distribution by the battery remaining amount distribution means is controlled so that the calculated power can be secured as the maximum power consumption for display. Such control is performed by the CPU.
[0036]
【The invention's effect】
As described above, according to the present invention, since the liquid crystal display time and the number of recordable images can be set and changed, the user can make settings according to his / her own use situation. In addition, since the necessary power is secured, the battery runs out when the user wants to take a picture or displays the taken picture, and the user can take a picture or display the picture with peace of mind.
