ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electronic still camera in which a recording medium having a large storage capacity, such as a hard disk, for example, is mounted.
2. Description of the Related Art
Conventionally, there is known an electronic still camera which uses a hard disk as a recording medium and image data can be recorded in the form of digital signals (Japanese Unexamined Patent Publication No. 6-90423). The storage capacity of a hard disk is considerably larger than that of a recording medium such as a floppy disk, and therefore a hard disk can store a larger amount of image data than a floppy disk.
The hard disk mounted in the conventional electronic still camera is used only for storing image data obtained by photography and information relating to the photography. Namely, the hard disk cannot be used for any other purpose when the electronic still camera is not in use, and thus the utility value of the hard disk is not so high.
SUMMARY OF THE INVENTION
Therefore, an object of the present invention is to provide an electronic still camera which can be used not only for recording image data but also as an external storage device for a computer.
According to the present invention, there is provided an electronic still camera comprising a recording medium, a mode select switch, first control means and second control means.
Reading and writing operations are carried out for a recording medium, while the recording medium is rotated, the recording medium being connected to an external computer. The mode select switch is provided for selecting one of a photographing mode, in which image data is recorded on the recording medium, or an external mode, in which the recording medium is operated as an external storage of the external computer. The first control means is provided for controlling the recording medium in such a manner that, in the photographing mode, a rotation of the recording medium is stopped after recording the image data on the recording medium. The second control means is provided for controlling the recording medium in such a manner that, in the external mode, a rotation of the recording medium is stopped when the recording medium has not been accessed by the external computer for a predetermined time.
Further, according to the present invention, there is provided an electronic still camera using a recording medium for recording image data, the electronic still camera comprising connecting means, a mode select switch, first control means and second control means.
The connecting means connects the recording medium to an external computer so that the external computer can access the recording medium. The mode select switch selects one of a photographing mode, in which image data obtained by the electronic still camera is recorded on the recording medium, or an external mode, in which the recording medium is accessed by the external computer. The first control means controls the recording medium in such a manner that, in the photographing mode, a rotation of the recording medium is stopped after recording the image data on the recording medium. The second control means controls the recording medium in such a manner that, in the external mode, a rotation of the recording medium is stopped when the recording medium has not been accessed by the external computer for a presetermined time.
Furthermore, according to the present invention, there is provided an electronic still camera using a recording medium for recording image data, the electronic still camera comprising connecting means, setting means and a mode select switch.
The connecting means connects the recording medium to an external computer so that the external computer can access the recording medium. The setting means sets a photographing mode so that image data obtained by the electronic still camera is recorded on the recording medium. The setting means sets an external mode so that the recording medium is accessed by the external computer. The mode select switch actuates one of the photographing mode setting means or the external mode setting means. The rotation of the recording medium is stopped after recording the image data on the recording medium in the photographing mode, and is stopped when the recording medium has not been accessed by the external computer for a predetermined time in the external mode.
