| Abstract: | According to the principle of formation image with optics lens. The relationships between images of near and far objects with camera lens and field of view and object distance and the image ratio are researched, and the formulas are obtained. Thus the contrast of near and far images can be controlled in the camera view. |

| Keywords: | camera view lens field of view object distance image ratio |
