    Abstract: A processor applies a first driving signal having a first driving frequency to a first actuator, applies a second driving signal having a second driving frequency to a second actuator, generates a first angle detection signal by performing first frequency filter processing based on the first driving frequency on an output signal of a first angle detection sensor, generates a second angle detection signal by performing second frequency filter processing based on the second driving frequency on an output signal of a second angle detection sensor, derives a first angle, which is an angle of a mirror portion around a first axis, based on the first angle detection signal, derives a second angle, which is an angle of the mirror portion around a second axis, based on the second angle detection signal, adjusts the first driving signal based on the first angle, and adjusts the second driving signal based on the second angle.

    Abstract: Provided are an information suggestion system, an information suggestion method, a program, and a recording medium capable of suggesting information of interest to many users to a product provider related to the information from an image group of a plurality of users.
    In the information suggestion system, the information suggestion method, the program, and the recording medium, an image group acquisition unit acquires an image group of a plurality of users, and an image analysis unit detects an imaging location of each image and an object appearing in each image. An imaging number count unit counts an imaging number of same-type images which are captured at the same imaging location and in which the same object appears, and an imaging frequency calculation unit calculates an imaging frequency of the same-type images. An information suggestion unit suggests same-type image information related to the same imaging location and the same object of the same-type image of which the imaging number and the imaging frequency satisfy a predetermined condition to a product provider related to the same-type image information.

    Abstract: Provided is a method of manufacturing a structure having a transparent fine uneven structural body formed by hot water treatment, in which a finer uneven structure is formed. Provided is a method of manufacturing a structure, the method being for manufacturing a structure including a substrate, and a transparent fine uneven structural body which is formed on a surface of the substrate by hot water treatment, including: a first step of forming a precursor film of the transparent fine uneven structural body on the substrate; a second step of forming a fine uneven structure on a surface of the precursor film; and a third step of subjecting, to hot water treatment, the precursor film on which the fine uneven structure is formed to form the transparent fine uneven structural body in which a peak value ν0 of space frequency of the unevenness of the fine uneven structure formed in the second step satisfies ν

    Abstract: There are provided an information suggestion system, an information suggestion method, a program, and a recording medium capable of suggesting, to a user, information on a product matching a hobby and the preference of the user from an image group of the user.
    In the information suggestion system, the information suggestion method, the program, and the recording medium, an image group acquisition unit acquires an image group of a user, and an image analysis unit detects an attribute of each image. An imaging number count unit counts an imaging number of same-attribute images, and an imaging frequency calculation unit calculates an imaging frequency of the same-attribute images. An imaging purpose estimation unit estimates an imaging purpose of the same-attribute images. A suggestion decision unit decides whether or not to suggest information on a product related to the imaging purpose of the same-attribute images to the user depending on whether the imaging number and the imaging frequency of the same-attribute images satisfy a predetermined condition, and an information suggestion unit suggests information on a product decided to be suggested to the user.
