Latest Patents
One of Hitoshi Nozue's latest patents is an optical device designed to prevent degradation in image quality caused by undesirable reflected and transmitted light. This invention focuses on the edge portion of an optical element, which includes an aperture blade or an ND filter. The design features an almost rhombic aperture formed by the cooperation of the aperture edges of two blades. Additionally, small saw-toothed and non-periodic uneven portions are created along the ridgelines of the aperture edge and the ND filter. These uneven portions reflect incident light beams in various directions, enhancing the overall image quality. Another notable patent involves an ND filter and aperture device that utilizes a plurality of darkness distributions. These distributions are designed to correlate with the darkness distribution for ND-filtering transmission light at the position of an aperture blade. This innovative approach allows for the creation of multiple ND filters from a single original photograph.
