Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、ビデオカメラ、特に小型ビデオカメラに適する撮像素子に関する。 The present invention relates to an image pickup device suitable for a video camera, particularly a small video camera.

【0002】[0002]

【従来の技術】[Prior Art]

従来、ビデオカメラ、あるいはスチルビデオカメラに組み込まれていた画像信 号を読み出す撮像素子は、MOS形撮像素子でもCCD撮像素子でも撮像面は横長の四 角形の形状をしていた。 Conventionally, the image pickup device for reading image signals, which has been built into a video camera or a still video camera, has a horizontally long rectangular shape on the image pickup surface regardless of whether it is a MOS image pickup device or a CCD image pickup device.

【0003】 そして、ビデオカメラ、あるいはスチルビデオカメラにより撮影された画像は 、モニターテレビにより再生して見ていたが、このモニターテレビに使われてい る画像を映すブラウン管は、既に完成された形として横長の四角形の映像面を持 ち、この映像面に映す様に出来ていたため、撮像素子の形状もこれに適した形と なっていたわけで、むしろ自然の成り行きであった。Then, the image taken by the video camera or the still video camera was reproduced and viewed on the monitor television, and the cathode ray tube for displaying the image used in the monitor television is in a completed form. Since it had a horizontally long rectangular image surface and was designed to be projected on this image surface, the shape of the image sensor was also suitable for this, which was rather natural.

【0004】 また、この様な撮像素子は数ミリ角という非常に小さいものであるため、目立 たない小型の例えば監視用ビデオカメラ、あるいは遠隔操作可能な小型の監視用 ビデオカメラの撮像素子として広く使われる様になっている。しかし、その撮像 素子が横長の四角形の形状であるため、一度に見える範囲が方向によって差があ り、監視の面で必ずしも満足が行くものでは無かった。Further, since such an image pickup device is a very small one such as a few millimeters square, it is used as an image pickup device of an inconspicuous small monitor video camera or a remotely operable small monitor video camera. It has become widely used. However, since the image sensor was in the shape of a horizontally long quadrangle, the range that could be seen at one time varied depending on the direction, which was not always satisfactory in terms of monitoring.

【0005】[0005]

【考案が解決しようとする課題】[Problems to be solved by the device]

この様に、撮像素子の撮像面が横長の四角形の形状をしているため、例えば監 視用ビデオカメラの撮像素子として使った場合、上記の様に一度に見える範囲が 方向によって差が出ることとなった。 In this way, since the image pickup surface of the image pickup element is in the shape of a horizontally long rectangle, when used as an image pickup element of a video camera for monitoring, for example, the range that can be seen at one time may differ depending on the direction. Became.

【0006】 また、全方位にわたって広い範囲が見える必要がある監視カメラは、同時に目 立たず、どこにでも設置可能とするため、可能な限り軽量、小型である必要があ った。In addition, a surveillance camera that needs to see a wide range in all directions must be as light and compact as possible in order to be inconspicuous at the same time and to be installed anywhere.

【0007】 軽量、小型であるということは、壁や天井等にビデオカメラを設置する場合、 それだけ簡単な設置器具で良く、また容易に取り付けられるということである。 更に遠隔操作可能なビデオカメラの場合も、比較的に簡単で軽量構造のパンニン グ、チルティング機能を持っていれば良いことになる。[0007] Light weight and small size means that when a video camera is installed on a wall, a ceiling or the like, a simple installation tool is enough and it can be easily installed. Furthermore, even in the case of a remotely controllable video camera, it would be sufficient if it had a relatively simple and lightweight panning and tilting function.

【0008】 本考案は、上記課題を解決するためになされたものである。The present invention has been made to solve the above problems.

【0009】 すなわち、全方位にわたって円形状に広い範囲が見え、且つ軽量、小型のビデ オカメラが製造可能な撮像素子を提供することを目的としたものである。That is, it is an object of the present invention to provide an image pickup device in which a wide range of a circular shape can be seen in all directions, and a lightweight and compact video camera can be manufactured.

【0010】[0010]

【課題を解決するための手段】[Means for Solving the Problems]

上記目的は、画像信号を読み出す撮像チップ及び該撮像チップを取り付けるパ ッケージが円形であることを特徴とする撮像素子によって達成されるものである 。 The above object is achieved by an image pickup device characterized in that an image pickup chip for reading out an image signal and a package for attaching the image pickup chip are circular.

【実施例】【Example】

図1、図2は本考案の実施例を示した図である。図1は本考案の実施例を拡大 して示した斜視図で、図2は本考案の実施例を、実際にケースに組み込んだ監視 用ビデオカメラの斜視図である。 1 and 2 are views showing an embodiment of the present invention. 1 is an enlarged perspective view showing an embodiment of the present invention, and FIG. 2 is a perspective view of a surveillance video camera in which the embodiment of the present invention is actually incorporated in a case.

【0012】 図1において、11は円形の撮像チップであり、撮像チップ11の撮像表面に結像 された画像の画像信号は、電気信号として読み出される。そして円形の撮像チッ プ11は、CCD撮像素子の様な垂直転送部、蓄積部、読出部等が必要無いMOS形撮像 素子によって作られている。In FIG. 1, reference numeral 11 denotes a circular image pickup chip, and the image signal of the image formed on the image pickup surface of the image pickup chip 11 is read out as an electric signal. The circular image pickup chip 11 is made of a MOS type image pickup device that does not require a vertical transfer unit, a storage unit, a read unit, etc., such as a CCD image pickup device.

【0013】 12は、円形の撮像チップと同様に円形の形状をしたパッケージであり、その前 面には円形の撮像チップ11が取り付けられている。そして撮像チップ11が取り付 けられている反対側の面には、撮像素子10を駆動し、画像信号を電気的信号とし て取り出すピン13が円形に植え込まれている。Reference numeral 12 is a package having a circular shape similar to the circular image pickup chip, and the circular image pickup chip 11 is attached to the front surface thereof. A pin 13 for driving the image pickup device 10 and taking out an image signal as an electrical signal is circularly implanted on the opposite surface to which the image pickup chip 11 is attached.

【0014】 撮像素子10のピン13は、使用する時はもちろん円形のプリント基板A、21に挿 入される。The pin 13 of the image pickup device 10 is of course inserted into the circular printed circuit boards A and 21 when it is used.

【0015】 更に、円形のプリント基板A、21にはプリント基板B、22が図示の様に直角に 取り付けられている。そしてプリント基板B、22には撮像素子10を駆動する駆動 IC、23が取り付けられ、またプリント基板B、22がプリント基板A、21と結合す る側と反対側の端面には、ケーブル24が接続されている。ケーブル24は、撮像素 子10、駆動IC23用の駆動電流を送り込んだり、撮像素子10が読み出した画像信号 を外部に送り出すことになる。Further, printed circuit boards B and 22 are mounted on the circular printed circuit boards A and 21 at right angles as shown in the drawing. A drive IC, 23 for driving the image pickup device 10 is attached to the printed circuit boards B, 22, and a cable 24 is provided on the end surface opposite to the side where the printed circuit boards B, 22 are connected to the printed circuit boards A, 21. It is connected. The cable 24 sends a drive current for the image pickup device 10 and the drive IC 23, and sends an image signal read by the image pickup device 10 to the outside.

【0016】 図2は、既に述べた様に、本考案の実施例を実際にケースに組み込んだ監視用 ビデオカメラの斜視図である。As described above, FIG. 2 is a perspective view of a surveillance video camera in which the embodiment of the present invention is actually incorporated in a case.

【0017】 図2において、ケース15の先端には撮影レンズ14が固定して組み込まれている 。撮影レンズ14は、監視カメラの場合は通常広角レンズが使用されており、また 被写体もある程度の距離以上のものを対象としている。この様な場合は、被写界 深度は充分に大きいので、ピント調整メカが無い固定焦点方式でも実用上問題の 無い鮮鋭な画像が得られる。In FIG. 2, a photographing lens 14 is fixedly incorporated in the front end of the case 15. In the case of a surveillance camera, a wide-angle lens is usually used as the taking lens 14, and the subject is intended to have a certain distance or more. In such a case, since the depth of field is sufficiently large, a sharp image with no practical problems can be obtained even with the fixed focus method without the focus adjustment mechanism.

【0018】 撮像レンズ14の後方には、撮像レンズ14のピント位置に撮像チップの撮像表面 が来る様に、且つ撮像チップの中心が撮像レンズ14の光軸と一致する様に撮像素 子10はケース15に組み込まれている。そして、撮像素子10のピンはプリント基板 20に挿入されプリント基板20とは電気的に接続される。そしてプリント基板20に 接続されているケーブル24はケース15の撮影レンズ14の反対側から引き出されて いる。Behind the image pickup lens 14, the image pickup element 10 is arranged so that the image pickup surface of the image pickup chip comes to the focus position of the image pickup lens 14 and the center of the image pickup chip coincides with the optical axis of the image pickup lens 14. It is built into case 15. Then, the pins of the image pickup device 10 are inserted into the printed circuit board 20 and electrically connected to the printed circuit board 20. The cable 24 connected to the printed circuit board 20 is pulled out from the side of the case 15 opposite to the taking lens 14.

【0019】 本考案の、円形の撮像チップが取り付けられた、円形の撮像素子10を組み込ん だ監視用ビデオカメラは、以上の様に構成されており、その形状、外観も図示の 通り非常にコンパクトにまとめられる様になっている。そして、前述の様に撮像 チップの形状が円形で、撮像チップの中心が撮像レンズ14の光軸と一致する様に 、撮像素子10はケース15に組み込まれているので、撮像チップにより読み出され る画像信号は、全方位にわたっての、撮影レンズ14の光軸を中心にした円形状の 広い範囲の画像信号と言うことになる。従って、この画像信号をモニターテレビ に映して見れば、上記と同じ全方位にわたっての、撮像レンズ14の光軸を中心に した円形状の広い範囲を、モニターテレビ上で監視出来ることになる。The surveillance video camera incorporating the circular imaging element 10 with the circular imaging chip attached according to the present invention is configured as described above, and its shape and appearance are very compact as shown in the drawing. It is designed to be summarized in. Then, as described above, the imaging element 10 is built in the case 15 so that the shape of the imaging chip is circular and the center of the imaging chip is aligned with the optical axis of the imaging lens 14. The image signal corresponding to the image signal in a wide range of a circular shape centered on the optical axis of the taking lens 14 in all directions. Therefore, when this image signal is displayed on a monitor television, a wide circular area centered on the optical axis of the imaging lens 14 can be monitored on the monitor television in the same omnidirectional directions as described above.

【0020】 また、撮像チップの面積が、本考案の円形の撮像チップと同じ面積の横長の四 角形の形状であった場合は、撮像素子も撮像チップと同様に横長の四角形となる 。そしてこの横長の四角形の撮像チップの対角線の長さは、当然のことながらこ れと同一面積の円形の撮像チップの直径より大となる。図3はこの状況を示した ものである。S1は直径Dの円の面積であり、S2は横長の四角形の面積であり 、両者の面積S1とS2は等しい。そして横長の四角形の対角線Lは円の直径D より明らかに大きい。従って同じ画角で考えた場合は、円形撮像チップの直径D より、横長四角形の撮像チップの対角線Lの方が長いので、横長四角形の方が焦 点距離の長い撮影レンズを必要とする。また、同じ全開F値の撮影レンズとする とレンズの直径も大きくなり従ってレンズ重量も重くなる。Further, when the area of the image pickup chip is a horizontally long rectangular shape having the same area as the circular image pickup chip of the present invention, the image pickup element also becomes a horizontally long rectangle like the image pickup chip. The length of the diagonal line of the horizontally long rectangular image pickup chip is naturally larger than the diameter of the circular image pickup chip having the same area as this. Figure 3 shows this situation. S1 is the area of a circle of diameter D, S2 is the area of a horizontally long quadrangle, and the areas S1 and S2 of both are equal. The diagonal line L of the horizontally long rectangle is obviously larger than the diameter D of the circle. Therefore, when the same angle of view is considered, the diagonal line L of the horizontally long quadrangular image pickup chip is longer than the diameter D of the circular image pickup chip, so that the horizontally long quadrangular image pickup lens requires a longer focal length. Further, if the same full open F value is used for the taking lens, the diameter of the lens also becomes large and the weight of the lens also becomes heavy.

【0021】 更に、前述の様に撮像チップが横長の四角形であれば、撮像素子も同様に横長 の四角形となるので、ケースも断面形状が横長の四角形となり、前述の撮像レン ズの大形化と相まってビデオカメラは一まわり大きくなることになる。この様に 撮像チップの、従って撮像素子の円形化はビデオカメラの軽量、小型化に重要な 要因となるわけである。Further, as described above, if the image pickup chip is a horizontally long quadrangle, the image pickup element is also a horizontally long quadrangle, so that the case is also a horizontally long quadrangle, and the image pickup lens is large in size. Combined with this, the video camera will become one size larger. Thus, the circularization of the image pickup chip, and hence the image pickup element, is an important factor in reducing the weight and size of the video camera.

【0022】 この様に本考案の円形の撮像素子を使ったビデオカメラは、全方位にわたって 、撮像レンズの光軸を中心にした円形状の広い範囲が見れる円形筒形の軽量、小 型ビデオカメラの製造が容易で、この様なビデオカメラは監視用のみでなく例え ばファイバースコープの代りとして使用する事も出来る。As described above, the video camera using the circular image pickup device of the present invention is a lightweight, small-sized video camera in the shape of a circular cylinder in which a wide circular range centered on the optical axis of the image pickup lens can be seen in all directions. Is easy to manufacture, and such a video camera can be used not only for surveillance but also as an alternative to a fiberscope, for example.
