DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to an electronic camera, that is, a camera for electronically recording an optical image and, more particularly, to an electronic camera having a detachable recording section using a memory, such as a disk, as a recording means.
A conventional electronic camera of this type consists of an image pickup section for converting an optical image into an electrical signal and a disk recording section for electronically or magnetically recording the electrical signal.
Alternatively, an electronic camera of this type has a solid-state memory, instead of a disk recording section, as the recording means, in order to eliminate its drawbacks.
However, the art as described above has the following drawbacks.
First, an electronic camera having a disk recording section as the recording means has the following drawbacks:
(1) Since a recording disk and a disk drive for driving the same have predetermined size, miniaturization of the entire camera is limited.
(2) A predetermined time interval is required for a rise time of disk rotation when recording of an image is started, and a shutter release opportunity can be lost.
(3) The power consumption required for a disk servo is comparatively large, and disk servo time not contributing to recording is prolonged.
(4) The camera housing must be water- and dust-proofed due to the necessity of disk change, resulting in a high cost.
Meanwhile, an electronic camera using a solid-state memory as a recording means has the following drawbacks:
(1) It is difficult to increase the memory capacity exceeding a predetermined degree, and a maximum number of photographing frames is smaller than that of an electronic camera which uses a disk.
(2) Since cost reduction of the memory is limited, reduction in photographing cost is also limited.
(3) A semiconductor memory requires power to maintain data of a recorded optical image, and it is difficult to reserve it permanently.
(4) If a replaceable memory pack is used to overcome the problem of the limited maximum number of photographing frames, the camera housing must be water- and dust-proofed, resulting in a high cost.
SUMMARY OF THE INVENTION
Therefore, an electronic camera according to the present invention has an image pickup section including an image pickup element and a solid-state memory for recording at least one-frame of image signals from the image pickup element, and an external recording section including a non solid state memory means are provided separately. The image pickup section and the external recording section are detachable. The invention is characterized by comprising a voice pickup means for obtaining voice data to be recorded on the solid-state memory.

FIG. 1 is a block diagram of an arrangement of an electronic camera according to an embodiment of the present invention.
The electronic camera of this embodiment basically comprises an image pickup section 1 and a disk recording section 2.
The image pickup section 1 has a lens 3 and an image pickup element 4. The image pickup element 4 forms an optical image from the lens 3 and converts the optical image into an electrical signal, i.e., an image signal. The image pickup element 4 comprises a known image pickup means such as CCD, a MOS, an image pickup tube and so on. A signal processing curcuit 5 processes the image signal from the image pickup element.
The image pickup
