DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic camera, and more particularly to an electronic camera on which a plurality of types of recording media for recording image signals can be mounted.

[0002]

2. Description of the Related Art Conventionally, an electronic still camera capable of recording a still image and sound using a magnetic disk as a recording medium has already been commercially available in an electronic camera. An electronic still camera using a memory card having a memory element has already been proposed.

However, the memory card has a limited recording capacity due to the degree of integration of the memory and the number of memory elements that can be mounted.
In addition, since the memory price is higher than other media, it cannot be used as a large-capacity recording medium at present.

On the other hand, if a large-capacity magnetic recording medium represented by a hard disk is used, large-capacity recording can be performed at relatively low cost.

[0005]

However, for example, in the case of an electronic still camera using a hard disk as a recording medium, large-capacity recording can be performed at low cost, but on the other hand, the recording speed is low and the recording medium is weak against vibration and impact.

On the other hand, in the case of an electronic still camera using a memory card as a recording medium, the recording speed is high and the device is resistant to vibrations and shocks, but on the other hand, it is expensive and cannot perform large-capacity recording. .

[0007] Under such a background, an object of the present invention is to provide an electronic camera which has solved the above-mentioned problems.

[0008]

In order to achieve the above object, an image recording apparatus according to the present invention is an image recording apparatus capable of simultaneously mounting a disk-shaped recording medium and a solid-state memory,
Input means for continuously inputting image data, recording means for recording the image data inputted by the recording means on the attached recording medium, and recording the image data on a disc-shaped recording medium or a solid-state memory When a user has a selection means for selecting whether to record image data in the disk, and a vibration detection means for detecting vibration of the image recording apparatus, and intends to record continuously input image data on a disk-shaped recording medium In response to detecting the vibration by the vibration detecting means, the selecting means changes the recording destination of the image data to the solid-state memory,
A continuous input of image data by the input means is continued.

[0009]

With the above arrangement, when the image data is to be recorded on the disk-shaped recording medium, the selecting means changes the recording destination of the image data to the solid-state memory in response to the detection of the vibration by the vibration detecting means. Continuous input of image data by the input means is continued.

The operation control of the electronic still camera configured as described above will be described in detail with reference to FIGS.

When the power is turned on, the system control circuit 32 initializes flags, control variables, and the like (step S1). When the main switch 40 is closed (step S2), the recording medium (the memory card 11 or the memory card 11 in this embodiment) is closed. It is checked whether the hard disk device 12) is mounted on the camera body (step S3).

If the recording medium is not connected to the camera body (step S3), a warning is displayed on the display device 29 (step S12), and the flow returns to step S2.

If the recording medium is connected to the camera body (step S3), and if the management data of the recording medium mounted on the camera body has not been read (step S3).
4) The management data of the mounted recording medium is searched (step S5). The details of this search operation will be described later.

If the management data has already been read and search (step S5) is unnecessary, step S5 is skipped.

In steps S8 and S9, for example, the frame speed in the continuous shooting mode is made faster when the memory card 11 is installed than when the hard disk device 12 is installed. Alternatively, when the memory card 11 is installed, the continuous shooting frame speed is maintained until the recordable area is exhausted, but when the hard disk device 12 is installed, the continuous shooting frame speed is continuously increased up to the number of images that can be recorded in the buffer memory 8. The continuous shooting is stopped when the frame speed is not maintained or when the number of images that can be recorded in the buffer memory 8 is reached. Thereby, continuous shooting according to the access time of the recording medium can be automatically performed.

Further, the compression ratio of the image compression circuit 6 is made lower when the hard disk device 12 is installed than when the memory card 11 is installed.

[0094]

As described above, according to the present invention, when the image data to be continuously input is to be recorded on the disk-shaped recording medium, the vibration is detected by the vibration detecting means. Since the selection unit changes the recording destination of the image data to the solid-state memory and continues the continuous input of the image data by the input unit, a disk-shaped recording medium such as a magnetic disk which is generally susceptible to vibration and shock is used. Even while inputting image data continuously,
It is possible to prevent such a failure in recording the image data on the recording medium. Then, it is possible to prevent continuous input of image data from being interrupted. Furthermore, when a recording medium that is resistant to vibration such as a semiconductor memory is used, it is possible to prevent unnecessary control of access due to the detection of vibration and to prevent photographing. .
