Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention stores a digital image signal obtained by converting an optical image signal of an object obtained by an optical system into an electric image signal by an image pickup device and further performing A / D conversion in a memory device. TECHNICAL FIELD The present invention relates to a still video camera that shoots by using a camera, and more particularly, to a technique for downsizing.

[0002]

2. Description of the Related Art In a conventional general camera, a captured optical image is formed on a silver salt film, so that the captured image cannot be viewed unless the film is chemically processed and developed. It is something. On the other hand, in recent years, a captured optical image is converted into an electric image signal, magnetically recorded on a medium such as a floppy disk formed of a magnetic material, and the magnetic signal recorded on this medium is converted into an electric signal. A so-called still image recording / reproducing system has been proposed which reproduces and displays an image signal on a TV monitor or the like. This system, by performing only electrical signal processing,
Because it has the advantage that no complicated chemical treatment is required,
It is gradually becoming popular in the market.

[0003]

By the way, in a still image recording / reproducing system of this type, for example, a still video camera or the like, an IC memory having a built-in semiconductor memory device as a recording medium and detachable from the camera body is provided. By using a card or a built-in memory in which a semiconductor memory element is mounted on the substrate built into the camera body, the image signal is converted into a digital signal and recorded, thereby achieving higher density recording and further reduction in size and weight. However, there is still a lot of room for improvement at the development stage.

For this reason, various improvements have been made, and in particular, there is an interest in reducing the size of the camera body. In the digital recording type still video camera described above, as described above, for example, since an IC memory card having a semiconductor memory element incorporated therein is used as a recording medium, the camera body is relatively thin.

[0005]

However, if additional parts such as a tele-converter for telephoto shooting and a wand converter for wide-angle shooting are attached to the camera body, the thickness of the camera body increases, and the use of an IC memory card or the like causes the camera to be used. The merits of making the main unit thinner are completely lost. In addition, as a conventional technique for reducing the size of a camera body, Japanese Patent Laid-Open No.
As shown in Japanese Patent No. 248767, there has been proposed a structure in which a portion provided with a lens system is formed in a bellows shape and can be folded in two.

However, with this device, the camera body can only be folded in half, so it cannot be said that the advantage of making the camera body thinner by using an IC memory card or the like is sufficiently brought out. In view of the conventional problems described above, the present invention provides a unique improvement in the thin structure of the camera main body, thereby sufficiently reducing the camera main body by using an IC memory card or the like. An object is to provide a still video camera adapted to be pulled out.

[0007]

Therefore, the still video camera of the present invention is obtained by converting an optical image signal of a subject obtained by an optical system into an electric image signal by an image pickup device and further performing A / D conversion. In a still video camera that stores a captured digital image signal in a memory device and shoots,
