摘要： A mode control section controls an image generation section to operate in a normal mode or a polarized light component reduction mode on the basis of a mode signal from a mode signal generation section to cause the image generation section to form a normal image or a polarized light component reduced image. When the possibility of occurrence of stray light is high, the imaging device automatically switches to the polarized light component reduction mode and when the possibility of occurrence of the stray light is low, the imaging device automatically switches to the normal mode. The polarized light component reduced image is obtained by reducing or eliminating stray light having a polarized light component, and the normal image is formed without reducing the stray light. Thus, the imaging device is capable of automatically switching between the two modes.
摘要翻译：模式控制部分根据来自模式信号产生部分的模式信号控制图像生成部分以正常模式或偏振光分量降低模式操作，以使图像生成部分形成正常图像或偏振光分量缩小图像。当发生杂散光的可能性高时，成像装置自动切换到偏振光分量降低模式，并且当杂散光的发生的可能性低时，成像装置自动切换到正常模式。通过减少或消除具有偏振光分量的杂散光获得偏振光分量缩小图像，并且形成正常图像而不减少杂散光。因此，成像装置能够在两种模式之间自动切换。
