    Abstract: Embodiments provide a smart optical filter capable of dynamically adjusting brightness variations in incident lights in a FOV or an optical field before an image sensor receives the incident lights. The smart optical filter in accordance with the disclosure can be portable and mounted on various imaging devices such as a smart phone or a camera. The smart optical filter may comprises an light adjustment layer made of an adaptive optical materials such liquid crystals. Light intensity distribution can be obtained for an FOV of a device coupled to the smart optical filter. The light intensity distribution can be compared to one or more thresholds to obtain difference values pixels on the light adjustment layer.

  • Patent number: 10473883
    Abstract: There are provided a variable magnification optical system and a control method thereof which are capable of relatively accurately adjusting a positional relationship between a variable magnification optical device and an imaging surface of an imaging device according to a zoom amount. A zoom lens included in the variable magnification optical device is positioned at a telephoto end and a wide angle end, and shift amounts ?S1 and ?S2, tilt angles ?1 and ?2, rotation angles ?1 and ?2, and focusing adjustment amounts ?1 and ?2 of the variable magnification optical device are set by a user and are stored. In a case where a zoom amount of the zoom lens is set to a desired value by the user, a shift amount corresponding to the set zoom amount is calculated by using the stored shift amounts ?S1 and ?S2. The positional relationship between the variable magnification optical device and the imaging surface of the imaging device is adjusted so as to have the calculated shift amount.

  • Patent number: 10473881
    Abstract: A lens unit is provided capable of reducing the shift of the focal position when the temperature rises. The lens unit includes a plurality of lenses and a cylindrical holder configured to internally hold the plurality of lenses. The holder has a smaller coefficient of thermal expansion, compared to single lenses (i.e., the second lens and the third lens) that are meniscus-shaped plastic lenses. The side surfaces of the second lens and the third lens are press-fitted such that the concave side portions corresponding to the positions of the concave lens surfaces abut the inner surface of the holder, the second lens and the third lens including the concave lens surfaces and the convex lens surfaces. Therefore, when the ambient temperature rises, the refractive index of the plastic lens decreases but the convex lens surface deforms such that the curvature radius becomes smaller.
