Patent number: 11971567Abstract: Provided is an optical film that can eliminate rainbow unevenness when viewed with the naked eyes and provide favorable color tone uniformity when viewed at an oblique angle. This optical film has a low-refractive index layer on a plastic film, the plastic film has a slow axis that is an axis with the largest refractive index in a plane, and a fast axis that is an axis orthogonal to the slow axis in the plane of the plastic film, and the low-refractive index layer is located on the surface of the optical film. Linearly polarized light is incident, under predetermined conditions, from a surface on a side opposite to the low-refractive index layer of the optical film, and transmitted light of the linearly polarized light is used to measure the a* value and b* value of the L*a*b* color system at 11 measurement points with different angles.Type: GrantFiled: October 21, 2021Date of Patent: April 30, 2024Assignee: DAI NIPPON PRINTING CO., LTD.Inventors: Shosei Kubota, Hikaru Hotta, Yoshiko Tanaka, Takashi Kuroda, Akinobu Ushiyama

Publication number: 20150244991Abstract: An image processing camera generates movement information on the basis of an omnidirectional image captured at a fixed field angle, and notifies PTZ camera of first movement information through a network. The PTZ camera analyzes the first movement information, changes a field angle to a specific monitoring target area. The image processing camera transmits second movement information to the PTZ camera. The PTZ camera analyzes the second movement information, captures a projected image of the specific monitoring target area when it is recognized that a current field angle is correct on the basis of the second movement information. Accordingly, an image of the specific monitoring target area is captured in a situation where there is no object such as a figure while monitoring a wide range.Type: ApplicationFiled: February 23, 2015Publication date: August 27, 2015Inventors: Junko Noda, Kosuke Hosoi, Akinobu Tanaka, Toshihiro Shimizu
