Publication number: 20250014141Abstract: Various factors can degrade the quality of camera images. For example, images can be distorted by rotation, shear, horizontal lens shift, and/or vertical lens shift. Such factors may result in perspective distortion of a subject being captured in a camera image by transforming horizontal and/or vertical lines of the subject and/or subject plane into lines that are at an angle to the horizon and/or the normal to the horizon in the image. Prior techniques that rely on search processes to find a homography for perspective correction in images can be time-consuming and computationally expensive. Moreover, these prior techniques may fail to find a solution that results in a corrected image of sufficient quality. The disclosed techniques overcome these drawbacks by applying fast homography transformations based on deterministic methods to align images that exhibit perspective distortion.Type: ApplicationFiled: November 18, 2022Publication date: January 9, 2025Applicant: Nikon CorporationInventor: Yuuya Takayama

Patent number: 12174355Abstract: A zoom optical system includes, in order from an object, a first lens group, a second lens group, and a third lens group having positive, negative, and positive refractive powers, respectively. The first lens group moves toward the object and air distances between the first to third lens groups vary upon zooming from a wide-angle end state to a tele-photo end state. The first lens group comprises a cemented lens consisting of a negative lens and a positive lens in order from the object. The following conditional expressions are satisfied: 4.40<f1/(?f2)<8.00 0.60<f3/fw<3.50 0.60<(?f2)/f3<1.05 30.00°<?w<80.000 f1, f2, and f3 denoting focal lengths of the first to third lens groups, respectively, and fw and ow denoting a focal length of the zoom optical system and a half angle of view in the wide-angle end state, respectively.Type: GrantFiled: August 2, 2022Date of Patent: December 24, 2024Assignee: Nikon CorporationInventors: Tomoki Ito, Hiroshi Yamamoto
