Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a digital camera for compressing digital image data and recording it on an image recording medium.

[0002]

2. Description of the Related Art Conventionally, as a digital camera for compressing digital image data and recording it on an image recording medium, for example, there has been a digital camera as shown in FIG.

FIG. 6 is a block diagram showing a configuration example of a conventional digital camera.

When the operation is started by operating the release button 12, the light beam from the subject passes through the lens 1 and is controlled to an appropriate amount by the shutter and the aperture 2, and is incident on the CCD 3, which is an image pickup device, and is photoelectrically converted. Thereafter, the signal processing circuit 4 performs a process such as γ correction to obtain an image signal.

This image signal is converted into a digital signal by an A / D conversion circuit 5 and then temporarily stored in a frame memory 20.
After a known data compression process is performed by a compression circuit 6, the data is recorded on a memory card 8 via a card I / F (interface) 7.

The display device 9 displays photographing information such as a shutter speed, an aperture value, the number of photographed frames, and the number of remaining frames. The LED 14 flashes during compression processing of the digital image data and recording on the memory card 8.

Reference numeral 10 denotes a control circuit for controlling each of the above circuits. In addition to a CPU for managing the entire camera, an interface circuit, a timing circuit for supplying a clock signal to each circuit, a power on / off control circuit, and the like are provided. Is included. Reference numeral 13 denotes various operation buttons. When an interlocked switch is operated, a process corresponding to the switch is performed by the control circuit 10. The power supply circuit 11 supplies a power supply voltage from a battery to each of the above circuits.

FIG. 7 is a rear view of the above digital camera, in which the same reference numerals as in FIG. 6 indicate the same functions.

The LED 14 blinks while writing to the memory card 8 to warn the photographer not to destroy the image data, such as disconnecting the memory card 8 or the power supply. The throttle cover 21 can be opened by depressing the lock member 22. Inside the memory card 8, the memory card 8, a throttle for mounting the memory card 8, and an ejection button are arranged. The battery cover 31 covers the battery storage unit, and can be opened by sliding and raising. A battery and a removal button for removing the battery are arranged inside the battery cover 31.

[0010]

However, in the above-described conventional digital camera, during writing to the memory card after the release, the LED 14 is used to operate the image data to be destroyed, such as when the photographer disconnects the memory card 8 or the power supply. Although the user is warned not to do so, the memory card 8 and the battery can be actually removed by operating the lock member 22 and the eject button while the LED is blinking. When these operations are performed, there is a possibility that the image data already written in the memory card 8 may be destroyed as well as the image data currently being written in the memory card 8.

In order to solve these problems, it has been proposed to lock the memory card 8 and the battery cover 31 electrically. However, when these devices run out of batteries, the memory card 8 and the battery cover 31 are locked. And have the drawback that the battery cannot be taken out, and has not been put to practical use.
