いた。Problems to be Solved by the Invention However, in the configuration in which the color temperature sensor 10 is disposed near the imaging lens 1 as described above, when adjusting the focus adjustment dial 11 and zoom ring 12 during shooting, The color temperature sensor 10 is detected by a part of the user's arm or hand.
The color temperature detection may not be successful and the color reproducibility may deteriorate.
問題点を解決するための手段
本発明は、かかる問題を解決するために、色温度センサ
１ｏに導かれる被写体の光像を、撮像レンズを通過した
光像の一部より得るよう構成したものである。Means for Solving the Problems In order to solve these problems, the present invention is configured such that the optical image of the object guided to the color temperature sensor 1o is obtained from a part of the optical image that has passed through the imaging lens. be.

レンズの操作時に、不用意に使用者の手等により色温度
センサを覆ってしまうというようなことはなくなるもの
である。Effects According to the above configuration, the color temperature sensor is configured to receive light passing through the imaging lens, so when operating the imaging lens as described above, there is no possibility that the color temperature sensor may be inadvertently covered by the user's hand or the like. This will no longer be the case.
実施例
以下本発明のビデオカメラの一実施例を図面を参照して
説明する。Embodiment An embodiment of the video camera of the present invention will be described below with reference to the drawings.
第１図は本発明のビデオカメラの一実施例の要部構成を
示す斜視図であり、撮像レンズ１から入射された光像は
、固体撮像素子等よりなる撮像素子２に照射され画像信
号に変換される。FIG. 1 is a perspective view showing the configuration of essential parts of an embodiment of a video camera according to the present invention. A light image incident from an imaging lens 1 is irradiated onto an imaging device 2 made of a solid-state imaging device or the like and converted into an image signal. converted.
この時、前記撮像レンズ１から入射した光の一部は撮像
素子２の垂直ブランキング区間等の画像信号に直接大き
く関係しない撮像エリアに設けられた反射鏡３によって
反射され、光路を上方へ向けて集光レンズ４，５．６お
よび光ファイバ７゜８．９で中継されて、色温度センサ
１０に導かれている。At this time, a part of the light incident from the imaging lens 1 is reflected by a reflecting mirror 3 provided in an imaging area that is not directly related to the image signal, such as the vertical blanking section of the imaging device 2, and directs the optical path upward. The light is relayed through condensing lenses 4, 5.6 and an optical fiber 7°8.9, and guided to a color temperature sensor 10.
すなわち、撮像レンズ１を通過した光の一部が色温度セ
ンサ１０に導かれるよう構成されている。That is, the configuration is such that a portion of the light that has passed through the imaging lens 1 is guided to the color temperature sensor 10.
発明の効果
以上の−ように本発明によれば、撮像レンズを通過した
光の一部が色温度センサ１ｏに導かれるよう構成しであ
