Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an electronic camera comprising an imaging device that converts a subject image into a still image signal corresponding to one frame, and an internal storage device capable of storing a plurality of frames of the still image signal. The present invention relates to a converter that transfers an image signal taken with a camera and stored in the internal storage device to another storage device and stores it again.

Conventionally, this type of camera has been designed to be smaller in order to improve portability. To this end, it is conceivable to reduce the storage capacity of the internal storage device, which requires a relatively large space, to reduce its size. This small-capacity internal storage device has a capacity of, for example, about 20 frames of still images, so
It is desirable to transfer the stored contents to an external large-capacity storage device so that they can be reused. Furthermore, it would be convenient if unnecessary image signals could be erased without being transferred.

SUMMARY OF THE INVENTION An object of the present invention is to provide a converter that removes unnecessary image signals when transferring the stored contents of a small-capacity storage device attached to an electronic camera to a large-capacity storage device.

FIGS. 1 and 2 show the appearance of an embodiment of an electronic camera used in the present invention. The camera includes a photographing unit 1 that photoelectrically converts a subject image into a still image signal;
Memory that stores one frame of still image information
It consists of a storage section 2 containing 20 frames. Both parts are separable as shown in Figures 3a and b.

A photographing lens 10 is attached to the front of the photographing section 1, and as shown in the cross-sectional view of FIG. do. Lens 10 has aperture 1
0a, a mosaic filter 11a for color separation is arranged in front of the image sensor 11. Furthermore, the imaging section 1 is provided with a finder 12 that penetrates from the front surface to the rear surface to define an imaging field of view, and as shown in FIG. An accessory shoe 14 and a release button 15 are provided. When the release button 15 is pressed lightly, a power supply switch inserted into the power supply circuit is turned on, and power is supplied. Along with this, a photometric operation is performed. When the release button 15 is pressed deeply, the power supply switch remains on and the photographing sequence is further started. Once the photographing sequence is started, it does not stop even if the release button 15 is released midway through. Also, the power supply switch remains ON until the shooting sequence ends. In FIG. 2, on the rear surface of the imaging unit 1 is a mode selection lever 16 for selecting one of a mode for automatically accessing memory cell addresses in the storage unit 2, a mode for manual access, and a mode for multiple exposure.
, a push button 17 for manual access, a 7-segment display device 18 such as a liquid crystal display for displaying the currently accessed memory address, and a switch 19 for disabling the audible warning device. . Furthermore, on the side of the imaging unit 1 are mounting screws 1 for attaching external accessories such as a data imprinting device or an electronic monitor device for monitoring the subject image.
00 and a connector 130 for the accessory are respectively provided.

As shown in FIG. 2, on the rear surface of the storage unit 2, there is a display device 201 such as a liquid crystal or electrochromic device for displaying used memory addresses, and a storage capacity (total number of memory cells, i.e., a memorizable frame). A label 202 on which a number) etc. are printed is provided. Further, there is a detachable slider 203 on the side as shown in FIG. 3b. When this is slid to the right, the attachment/detachment key 204 protruding from the top surface of the storage section 2 slides in the same direction, and the locking key 204, which is not shown in the corresponding part of the imaging section 1, is disengaged and the storage section 2 can be removed from the imaging section 1. The storage section 2 is provided with a T-groove 205, which engages with and guides the guide member 131 on the imaging section side during attachment and detachment.

Furthermore, a connector 206 and pins 207 are provided upright on the upper surface of the storage section 2 . The connector 206 is connected to a corresponding connector (not shown) of the imaging unit 1 to mutually transmit electrical signals. The pin 207 mechanically transmits the storage capacity of the storage unit 2 to the imaging unit 1.

FIG. 5 illustrates the internal structure of the imaging element 11 of the imaging section 1. This is a CCD image sensor that uses a so-called interline charge-coupled device (CCD).

Claims (1)

[Claims] 1. A converter having a second storage means connected to a first storage means storing image signals of a plurality of frames photographed and stored with an electronic camera, and storing the image signals transferred from there, Prior to this, means for sequentially reproducing each image signal of the first storage means on a monitor and generating a signal indicating whether or not transfer is necessary for each image signal, and a necessity storage means for storing the necessity signal; The converter is characterized in that, based on the output of the necessity storage means, only the required image signals among the image signals stored in the first storage means are transferred and stored in the second storage means. .
