Abstract: An additive manufacturing path generation apparatus includes: a formation path generation unit that divides an additive manufacturing object into layers that are units of formation of the additive manufacturing object such that a formation height of a bead that forms the layers does not exceed an upper limit and generates formation paths that are paths for formation of the divided layers from layer definition information and a formation path surface, the layer definition information defining division of the additive manufacturing object into the layers, the formation path surface being a surface restricting positions of the formation paths; and a formation path correction unit that corrects the formation paths to a formation path that causes a plurality of layers to be partially formed in a collective manner while maintaining the formation height within a range between the upper limit and a lower limit.

Abstract: In an automatic tracking process using an aim color, a technique of allowing an observer to confirm the aim color set in the imaging device with ease is provided. An image display device using this technique has a display control unit 211 configured to input video signals obtained as a result of a tracking process using an aim color and color information showing the aim color, the video signals and the color information being generated from an imaging device, and also configured to combine an image based on the video signals with an image based on the color information, and a tracked object indicating unit 212 configured to accept an indication against an object to be tracked in the tracking process, from an outside.
