Latest Patents
Okajima's latest patents include a zoom lens and imaging apparatus. This innovative design implements four lens groups, including a first lens group with positive refractive power, a second lens group with negative refractive power, a third lens group with positive refractive power, and a fourth lens group with positive refractive power. The design allows for effective movement of the second lens group towards the image side when transitioning from a wide-angle to a telephoto state. Additionally, the fourth lens group compensates for image plane variation caused by this movement. Another notable patent is an exposure control method for imaging apparatuses. This method involves adjusting an ND filter based on the brightness level of an object. When the brightness is below a predetermined level, the ND filter is removed to fully open the iris opening. Conversely, when the brightness exceeds the predetermined level, the ND filter is placed to fully close the iris opening. This innovative approach ensures optimal exposure control in varying lighting conditions.
