として得られるようにしたものである。Conventional Structure and Problems Conventionally, as shown in FIG. 1, this type of solid-state camera has a vertical shift register 1 and FETs 2, . A photodiode 3 connected to the same FET 2, a horizontal shift register 4, and an amplifier 6 are formed, and a vertical shift register 4 connects one horizontal
The output of the photodiode 3 is read out to the vertical transmission lines v1 to 4 through the FET 2 connected every 4, and this signal charge is taken out in time series by the horizontal/foot register 4, and then sent through the amplifier 6 to the output terminal 6 for solid-state imaging. This is so that it can be obtained as an element output.
しかしながら、このような固体カメラの場合。However, for solid-state cameras like this.
電子ビームによる走査でないために画像の上下反転がで

するためには光学的なミラー等によ−）て反転を行なう
ことにより諸口的を達成できるが、スペース、コスト上
問題がある。さらに一つのカメラを両用に兼用すること
は機構的に複雑さを増す原因ともなる。Since it is not scanned by an electron beam, it has the disadvantage that the image cannot be flipped upside down. In order to determine this ff:jfl'-11, it is possible to accomplish this by inverting it using an optical mirror or the like, but this poses a problem in terms of space and cost. Furthermore, using one camera for both purposes increases mechanical complexity.
発明の目的
本発明はこのような従来の欠点を除去したもので、上下
反転の画像が容易に得られるようにしたものである。OBJECTS OF THE INVENTION The present invention eliminates these conventional drawbacks and makes it possible to easily obtain a vertically inverted image.

ものである。Structure of the Invention In order to achieve the above object, the present invention provides two vertical shift registers with different scanning directions, and also provides means for selecting one of the shift registers depending on the application.
実施例の説明 以下、本発明の一実施例を第２図を参照して説明する。Description of examples An embodiment of the present invention will be described below with reference to FIG.

トレジスタ４に供給される。In FIG. 2, 1 to 6 have the same functions as 1 to 6 in FIG. 11 is a vertical shift register whose scanning direction is opposite to that of vertical shift register 1; 13 is a switching signal input terminal; 12 is a vertical shift register 1.11
In this switching circuit, for example, if 1" is applied manually, shift register 1 is selected, and if ○" is applied, soft register 11 is selected, and F is selected according to the scanning.
The output of ET2 is supplied to the horizontal shift register 4 through vertical transmission lines v1 to 4.

When 1" is added to , vertical shift register 1 is selected, and the output of photodiode 3 is transferred from horizontal shift register 4 to horizontal scanning lines H1, H2,
The signals are output in the order of H5 and H4.

とか出来る。In addition, 41 (
) When 11 is added, the vertical shift register 11 operates. Since the scanning direction of the vertical shift register 11 is opposite to that of the vertical shift register 1, the horizontal scanning lines H4, H5, H2, H, etc. are outputted from the output terminal 6 in the order of v1v2, . . .
- A signal in the order of v4 is obtained, and it is possible to invert the image downward.
発明の効果

下反転が容易であ一す、実用上有利である。Effects of the Invention As described above with reference to the embodiments, the present invention allows the screen to be easily flipped upside down, which is advantageous in practice.
捷だ光学的手段によるものに比べ小型でがっ安価であり
、しかも精度の向上がはがれる利点を有する。It has the advantage that it is smaller and much cheaper than the method using simple optical means, and it also has the advantage of improving accuracy.
