摄像单元
摘要：
提供一种能够降低摄像元件生成的图像信号中所产生的噪声的摄像单元。被设置于内窥镜的前端部(24)的摄像单元(240)具备：摄像元件(242)，其通过接收光并进行光电转换来生成电信号；振荡器(243)，其生成用于驱动摄像元件(242)的时钟信号；光电元件(244)，其将摄像元件(242)所生成的电信号转换为光信号并向外部输出；以及调节器(245)，其将从外部输入的电力转换为与摄像元件(242)、振荡器(243)以及光电元件(244)分别对应的电力并将转换得到的电力分别提供给摄像元件(242)、振荡器(243)以及光电元件(244)，其中，在前端部(24)内摄像元件(242)相距调节器(245)的距离比振荡器(243)和光电元件(244)相距调节器(245)的距离远。
摘要（英）：

Provided is an imaging unit capable of reducing noise that occurs in an image signal generated by an imaging element. An imaging unit (240) provided at a tip portion (24) of an endoscope includes an imaging element (242) that generates an electrical signal by receiving light and performing photoelectric conversion, an oscillator (243) that generates a clock signal for driving the imaging element (242), an photoelectric element (244) that converts the electrical signal generated by the imaging element (242) into an optical signal and outputs it to the outside, and a regulator (245) that converts electric power input from the outside into electric power depending on each of the imaging element (242), the oscillator (243), and the photoelectric element (244) and supplies the converted electric power thereto. At the tip portion (24), the imaging element (242) is spaced farther than the oscillator (243) and the photoelectric element (244) from the regulator (245).
