  • Publication number: 20210084268
    Abstract: There is provided an image processing device, an image processing method, a program, and a projection system that reduce processing in a case where images based on an equidistant cylindrical image are projected using a plurality of projectors. The image processing device of an aspect of the present technology generates a second equidistant cylindrical image whose center pixel is equal to a center pixel of each of projection regions of a plurality of projectors in a first equidistant cylindrical image and that includes pixels within an angle range including the each of the projection regions, as an image used to generate each of projection images that are projected from the plurality of projectors. The present technology is applicable to a computer that causes the plurality of projectors to project images.

  • Publication number: 20200307671
    Abstract: A steering shaft according to an aspect of the present invention includes an upper shaft, a lower shaft, and a seal cap. The seal cap includes a seal which comes into close contact with an inner peripheral surface of the upper shaft and a closure which bulges upward with respect to the seal. The closure is plastically deformed downward, and thus, the seal cap is held in an upper end opening portion in a state where the seal is pressed against the inner peripheral surface of the upper shaft.
