Abstract: A display system includes an HMD mounted on a head of a user, and a control device coupled to the HMD, the HMD includes an image display unit, with an outside scene being visible, for displaying a display image overlapping the outside scene, and a main control unit for causing an image display unit to display a display image, and the control device includes a touch panel, and a CO control unit for causing a related image related to a display content of the display image to be displayed on the touch panel.

Abstract: Provided is an image display method for performing drawing in a display region overlapping at least with a part of an external scene in a state in which the external scene is visible. The image display method images a region including the display region, and extracts an operating object from a captured image in which this region is imaged, as a region of a color of the operating object. In accordance with a size of the region of the color thus extracted, a drawing mode of the operating object is changed, and image display in the display region is controlled in accordance with the changed drawing mode. As the control of the image display, for example, performing drawing, and moving or replicating a drawn image is assumed.

Abstract: An operating method of a display system including an HMD including an image display unit, with an outside scene visible, for superimposing and displaying an image on the outside scene, and a DP outer camera mounted on the image display unit, the display device being configured to be mounted on a head of a user, and a control device having a touch panel for accepting operation, the operating method including displaying an operation image for accepting operation by the user on the touch panel, displaying an adjustment image for adjusting a captured image captured by the DP outer camera, in a display region of an image of the image display unit, changing a display position of the adjustment image by operation on the operation image, and causing the DP outer camera to perform imaging by operation on the operation image.

Abstract: Provided are an aberration corrector that reduces irregularity of a magnetic field of a multipole to obtain an image of high resolution and a charged particle beam apparatus using the same. The aberration corrector includes a plurality of magnetic field type poles, a ring that magnetically connects the plurality of poles with one another and an adjustment member disposed between the pole and the ring to adjust a spacing between the pole and the ring per pole.
