PURPOSE: A lens system is provided to enable miniaturization and embody high definition. CONSTITUTION: A first lens(L1), a second lens(L2), a third lens(L3), a fourth lens(L4), and a fifth lens(L5) are successively placed on an image from an object. An infrared filter(F) is placed on a path from the lenses to an image sensor(I) and removes unnecessary noise among light sources flowing in the image sensor. The unnecessary noise is removed among the light sources flowing in the image sensor. The image sensor senses the light source incident through the lenses and converts the light source into the electric signals. |
