  • Publication number: 20240040247
    Abstract: A method for capturing a subject, using an image capturing device mounted on a mobile apparatus. The image capturing device divides a target area of the subject into a plurality of image capturing areas in a moving direction of the mobile apparatus, and captures the plurality of image capturing areas, while moving with the mobile apparatus. The method includes: setting, as a focusing condition for the image capturing device, a focus distance that is commonly used to capture the plurality of image capturing areas in the target area, such that the plurality of image capturing areas are within depth of field; and capturing, with the image capturing device, the plurality of image capturing areas at the focus distance that is set as the focusing condition.

  • Publication number: 20180264703
    Abstract: Provided is a method for forming resin film capable maximizing the effective width of the resin film while suppressing neck-in and so increasing the material utilization. The method includes: drawing molten resin extruded downward from a die exit by a cooling roll; blowing air to both ends of the molten resin from an air-blowing nozzle to cure the both ends of the molten resin while cooling the molten resin on a surface of the cooling roll for solidification. For an effective width of the resin film to be formed having a thickness in a predetermined thickness range, a target effective width is set. An amount of air to be blown and a distance from the air-blowing nozzle to the molten resin are set to form the resin film having an effective width of the target effective width or more. The resin film is formed while blowing air under the conditions.
