【発明の詳細な説明】
ても電子カメラとしても使用し得る一眼レフカメラに関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a single-lens reflex camera that can be used both as an electronic camera and as an electronic camera.
最近になってＣＯＤやＭＯＳ イメージセンサ−等の
固体撮像素子を利用した電子カメラが、省銀の面からま
た撮影直後に再生が可能である等の利点から注目されて
きた。しかしながら、撮像素子の感度，解像度の点では
銀塩フィルムが遥かに優れている。従って、使用する側
から見れば、銀塩フィルムと固体撮像素子の各々固有の
メリットを生かした銀塩フィルム，固体撮像素子兼用カ
メラがあると便利である。Recently, electronic cameras using solid-state image sensors such as COD and MOS image sensors have been attracting attention because of their advantages such as saving money and being able to play back images immediately after taking pictures. However, silver halide film is far superior in terms of sensitivity and resolution of the image sensor. Therefore, from the user's perspective, it would be convenient to have a camera that can be used with both silver halide film and solid-state image pickup devices, which takes advantage of the unique advantages of both silver halide film and solid-state image pickup devices.
本発明は、以上の点に鑑み、銀塩フィルム用一眼レフカ

点板である。In view of the above points, the present invention aims to provide a single-lens reflex camera that can be used both as a silver halide film single-lens reflex camera and as an electronic camera. To explain this, 1 is the photographic lens, 2
3 is a quick return mirror, 3 is a pentaprism, 4 is an eyepiece, 5 is a film surface, 6 is a solid-state image sensor 6a disposed at the position of a focus plate in a general single-lens reflex camera, and a thin display plate 6b. A part of the viewfinder, 7, is a processing circuit to which a signal from the solid-state image sensor 6a is input and outputs an image reproduction signal to the display plate 6b.
is a general focus plate arranged so as to be switchable with the finder part 6.

えずに、そのままファインダ一部６を使用してもよい。The camera according to the present invention is constructed as described above, and when used as an electronic camera, the quick return mirror 2 is fixed in the state shown in the figure, and the finder part 6 is arranged in the finder optical system as shown in the figure. do it. At this time, the image formed on the solid-state image sensor 6a1 is transmitted to the processing circuit 7.
This reproduced image is reproduced on the display board 61) via the pentaprism 3. It can be observed through the eyepiece 4. Furthermore, the image formed on the solid-state image sensor 6a is
The data can be stored in the processing circuit 7 and further sent to a recording device (not shown) for recording and storage. When used as an eye reflex camera for silver halide film, by releasing the fixation of the quick return mirror 2 and switching to the focusing plate 8, a single eye reflex camera similar to the conventional one can be constructed. In this case, the finder portion 6 may be used as is without switching to the focus plate 8.
尚、焦点板８．ファインダ一部６は、従来の交換式焦点

効果的である。As described above, according to the present invention, the mirror can be used as both an eye-reflex camera and an electronic camera with a simple operation of fixing or releasing the mirror and switching to part of the viewfinder or focus plate. It is very effective because it is possible to take advantage of the unique advantages of each method and switch between them as necessary.
