DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a camera device according to an embodiment of the present invention will be described with reference to the drawings. FIG.
FIG. 1 is a block diagram illustrating the overall configuration of a camera device according to the present embodiment. FIG. 2 is a control flow showing an example in which the recording speed of the recording device is controlled based on the remaining amount of the battery. FIG. 3 is a control flow showing an example in which the printing speed of the printing apparatus is controlled by the printing resolution.

First, the configuration and operation of the camera device will be described with reference to FIG. A photographing lens 2 is attached to the camera device 1, and a subject is formed as an optical image on the optical axis of the photographing lens 2. This optical image is a photoelectric conversion element CC
D3 performs photoelectric conversion. The A / D circuit 4 converts the photoelectrically converted image data from analog data to digital data. Then, the image data converted into the digital data is temporarily stored in the memory 5. The image data stored in the memory 5 is input to the signal processing circuit 6 and is converted into compressed data.

The mode selection section 7 is an input section for the user to select a mode at the time of photographing. Here, the mode selection means instructing the automatic mode or the manual mode of the recording speed, directly instructing the high-speed recording or the low-speed recording, instructing the size of the recording resolution, and instructing the moving image recording or the still image recording. Or to instruct continuous shooting or intermittent shooting of still images. As for the recording speed, only in the automatic mode,
It is assumed that there are camera devices each having a function of selecting the automatic mode and the manual mode only in the manual mode.

The CPU 8 is a control section that generates various control signals based on the mode information input from the mode selection section 7. That is, the CPU 8 identifies the photographing mode instructed by the mode selection unit, instructs the recording device 9 to record or reproduce image data, and performs recording according to the contents of the mode setting and the power consumption state of the power supply unit 11. It instructs the device 9 to increase or decrease the recording speed. After driving the recording device 9, the CPU 8 instructs the recording device 9 to input the image data compressed by the signal processing circuit 6.
The image data may be uncompressed. Thereafter, the recording device 9 records the input image data on a recording medium.
As the recording device 9, there is an apparatus using a recording medium such as a flash memory, a flexible disk, a magnetic tape (tape recording medium), or a magneto-optical disk (disk recording medium).

The image data recorded on the recording medium is expanded by the signal processing circuit 6 and displayed on the monitor 10. The power supply unit 11 switches to a power supply supplied via a built-in battery 12 and an external power supply terminal 13 and supplies necessary power to the monitor unit 10 and the recording device 9 and other circuits. A remaining battery level detection circuit 14 is provided in the power supply unit 11. The remaining battery level detection circuit 14 monitors the remaining level of the battery 12 and transmits the remaining level to the CPU 8.

Next, a method of controlling the recording speed based on the remaining amount of the battery will be described with reference to FIG. 2 in comparison with FIG. An external power supply is not connected to the external power supply terminal 13, and the camera device 1 operates on the built-in battery 12. In this state, when the user of the camera device 1 selects the shooting start mode with the mode selection unit 7 or when the next shooting is instructed after the end of the shooting, the processing of the recording speed in step a1 starts. In step a2, it is determined whether or not the automatic mode has been selected by the user. If the automatic mode has not been selected, it is determined that the manual mode has been selected, and the flow branches to step a3. In this step a3, it is determined whether or not the low speed mode is selected by the user. If the low speed mode is selected, the process branches to step a5, and the recording speed is set to low speed. In step a3, if the low speed mode is not selected, it is determined that the high speed mode is selected, and the flow branches to step a6 to set the recording speed to high speed.

On the other hand, if the automatic mode is selected in step a2, the flow branches to step a4 to determine whether or not the remaining battery charge is less than a predetermined value A. If the battery level is equal to or higher than A, it is determined that the battery level is sufficient, and the process proceeds to step a6, where the recording speed is set to high. If the remaining battery level is less than A in step a4, it is determined that the remaining battery level is low, and the flow branches to step a5 to set the recording speed to a low speed.

Now, there are cases where the user wants to photograph many still images using the camera device 1. In such a case, the mode selector 7 selects the manual mode and further selects the low-speed mode. In this case, the process proceeds to step a5 according to the determinations in step a2 and step a3. In step a5, the recording speed of the recording device 9 is set to a low speed. As a result, a still image is shot while battery consumption is suppressed, so that a large number of frames can be shot for a long time.

When the subject is performing a motion with motion, it is necessary to continuously shoot still images. In such a case, the manual mode may be selected by the mode selection unit 7 and the high-speed mode may be further selected. In this case, the process proceeds to step a6 according to the determinations in step a2 and step a3. In step a6, the recording speed of the recording device 9 is set to a high speed. As a result, high-speed recording becomes possible, and the photographing interval can be shortened.

If the photographer does not care about the recording speed of the recording device 9, the mode selector 7 may select the automatic mode. In such a case, it is determined in step a2 that the mode is the automatic mode, and the process proceeds to step a4. Here, it is determined whether or not the remaining battery level is less than A. If it is not less than A, it is determined that the remaining battery level is sufficient, and the process proceeds to step a6. In step a6, the recording speed is set to a high speed. If it is determined in step a4 that the remaining battery level is less than A, it is determined that the remaining battery level is low, and the process proceeds to step a5. In step a, the recording speed is set to a low speed.

With the above processing, the user of the camera device 1 does not need to worry about the recording speed of the recording device 9, and the battery consumption can be suppressed by automatically lowering the recording device 9 speed. With these control methods, consumption of the battery is suppressed, and a camera device with high user convenience is obtained.

Next, a method of controlling the recording speed based on the magnitude of the recording resolution will be described with reference to FIG. 3 in comparison with FIG. Also in this case, no external power supply is connected to the external power supply terminal 13, and the camera device 1 operates on the built-in battery 12. FIG. 3 shows a control flow in which the printing speed of the printing apparatus is controlled by the printing resolution, but the processing other than step b4 is equivalent to the processing in which step ai in FIG. 2 is replaced with step bi. Therefore, only the supplementary part will be described here.

As one of the modes when the mode is selected by the mode selecting section 7, there is a mode in which the resolution of a still image can be selected. If you select a large resolution, for example, 10
It becomes a still image of 24 * 768 pixels. When the resolution is selected to be small, a still image of, for example, 640 pixels * 480 pixels is obtained. Even when these modes are selected to perform photographing, when the recording speed of the recording device 9 is determined, the operation starts from the processing of the recording speed in step b1. In step b2, it is determined whether or not the automatic mode has been selected by the user.

If the automatic mode has not been selected in step b2, it is determined that the manual mode has been selected, and the flow branches to step b3. Here, it is determined whether or not the low speed mode is selected by the user. If the low speed mode has been selected, the flow branches to step b5, and the recording speed is set to low speed. If it is determined in step b3 that the low-speed mode has not been selected, it is determined that the high-speed mode has been selected, and the flow branches to step b6. Step b
In 6, the recording speed is set to high speed.

If the automatic mode is selected in step b2, the flow branches to step b4. In step b4, it is determined whether or not the resolution at the time of shooting has been selected to be small.
If the resolution is high, the process branches to step b6, where the recording speed is set to high. If the resolution is low in step b4, the flow branches to step b5, and the recording speed is set to low.

There are cases where the user wants to shoot many still images. In such a case, the mode selection section 7 selects the manual mode and further selects the low-speed mode. In this case as well, the photographing is performed while suppressing the consumption of the battery, so that many photographing can be performed without replacing or charging the battery.

When a photographer shoots a moving subject, a still image may be shot continuously. In such a case, the mode selection unit 7 selects the manual mode and further selects the high-speed mode. In this case as well, high-speed recording becomes possible, and the photographing interval can be shortened.
If the photographer does not care about the recording speed of the recording device 9,
The mode selection unit 7 selects an automatic mode. In this case, it is determined in step b2 that the mode is the automatic mode, and the flow branches to step b4. In step b4, it is determined whether the resolution is low. If the resolution is large, the file size becomes large, so the shooting interval becomes large unless the recording speed is increased. Therefore, the process branches to step b6, and the recording speed is set to a high speed. When the resolution is determined to be small in step b4, the file size is reduced. In this case, the process branches to step b5, and the recording speed is set to a low speed.

Thus, the user does not need to worry about the recording speed of the recording device 9, and can automatically switch the recording device 9 to a low speed or a high speed, so that the consumption of the battery can be suppressed. In this case, a highly convenient camera device with reduced battery consumption can be obtained.

Next, as one of the cases where the mode in which the photographing is performed is selected by the mode selecting unit 7, not the resolution but the continuous photographing mode in which the photographing is continuously performed or the single photographing mode in which the photographing is performed in a single shot. Consider the case of choosing. In this case, the process of step b4 in FIG. 3 may be replaced with a process of determining whether the shooting mode is the single shot mode or the continuous shooting mode. That is, step b
At 4, it is determined whether or not the single-shot mode is set. If the single-shot mode is not set, it is determined that continuous recording is necessary for the continuous shooting mode, and the process branches to step b6. In step b6, the recording speed is set to a high speed.
When the single shot mode is determined in step b4, the process branches to step b5. Since the photographing interval becomes long in the single shot mode, the recording speed is set to low in step b5. By performing such processing, it is possible to obtain a camera device that is highly convenient for the user while suppressing battery consumption.

Next, as one of the cases in which the mode selection unit 7 selects a mode for performing shooting, a case in which a moving image shooting mode or a still image shooting mode is selected instead of the resolution is considered. In this case, the process of step b4 in FIG. 3 may be replaced with a process of determining whether the mode is the still image shooting mode or the moving image shooting mode. That is, it is determined in step b4 whether or not the camera is in the still image shooting mode. If the camera is not in the still image shooting mode, it is determined that continuous recording is necessary since the camera is in the moving image shooting mode, and the process branches to step b6. I do. In step b6, the recording speed is set to high speed. Step b4
If it is determined in step b5 that the camera is in the still image shooting mode, step b5
Branch to Since the shooting interval is long in the still image shooting mode, the recording speed is set to low in step b5. By performing such processing, it is possible to obtain a camera device that is highly convenient for the user while suppressing battery consumption.

In the above-described embodiment, when the recording medium is a disk-shaped recording medium or a tape-shaped recording medium, the power consumption when driving the recording device 9 is larger than that of a semiconductor memory such as a flash memory. In such a case, most of the power consumption of the battery 12 of the camera device is consumed by the recording device 9. The control method that gives priority to the remaining amount of the battery as in the present embodiment provides a camera device that is highly convenient for the photographer when used outdoors where there is little chance of battery replenishment.

[0035]

According to the first aspect of the present invention, when the remaining amount of the battery becomes small, the recording apparatus automatically switches the recording speed to a low speed, so that the consumption of the battery can be reduced. it can. For this reason, more images can be recorded by one charge or exchange of the battery than originally.

According to the second aspect of the present invention, when the user instructs automatic setting, high-speed recording or low-speed recording is automatically set based on the remaining battery power. When the user instructs the manual setting, the subject is photographed at the recording speed instructed by the user. As described above, the camera device can be selectively used depending on the purpose of use, and the consumption of the battery can be reduced as a whole. For this reason, many images can be recorded, and the battery capacity can be effectively used.

According to the third and fourth aspects of the present invention, the recording speed can be automatically changed according to the resolution selected by the user. For this reason, the consumption of the battery can be reduced as a whole, many images can be recorded, and the battery capacity can be used effectively.

According to the fifth and sixth aspects of the present invention, the recording speed can be automatically changed according to the case where the user selects continuous shooting or single shooting. For this reason, the consumption of the battery can be reduced as a whole, many images can be recorded, and the battery capacity can be used effectively.

According to the seventh and eighth aspects of the present invention, the recording speed can be automatically changed according to the case where the user selects moving image shooting or still image shooting. For this reason, the consumption of the battery can be reduced as a whole, many images can be recorded, and the battery capacity can be used effectively.

When the recording medium is a disk-shaped recording medium or a tape-shaped recording medium, generally, the power consumption of the recording device is increased and the battery is quickly consumed. In the case of a camera device having such a recording device, by adopting a control method that considers battery consumption as in the inventions of claims 9 and 10, the photographing time of the camera device can be lengthened and one battery operation can be performed. The camera device can be used many times by charging or exchanging the camera.
