Abstract: A client terminal (200) acquires a ticket (110) including a scope indicating an authorization condition, collects a context to indicate a state of the client terminal, sets the context in the ticket, and transmits the ticket. The authorization server (400) receives the ticket, determines a condition element other than the context among one or more condition elements indicated in the authorization condition as reinforcement information (111), requests the reinforcement information determined to a context reinforcement device (500), receives the reinforcement information, and verifies the scope based on the context and the reinforcement information.

Abstract: A synthetic image generation apparatus has a digital surface model (DSM) generator, a slope map generator, a curvature map generator and a synthetic image generator. The digital surface model (DSM) generator meshes three-dimensional point group data and generates a DSM including height of a building and vegetation. The slope map generator calculates a slope amount in accordance with the DSM and generates a slope map expressing levels of the slope amounts with shading in two colors. The curvature map generator smooths the DSM, calculates curvature in accordance with the smoothed DSM, and generates a curvature map expressing bumps and dips according to the curvature with shading in two colors. The synthetic image generator generates a synthetic image obtained by superimposing the slope map transmitted at first transmittance, the curvature map transmitted at second transmittance, and an orthochromatic image.

The controller finishes focusing operation without driving the lens when the defocus amount is out a range of a first in-focus determination width, and performs the focusing operation when the defocus amount is out a range of the first in-focus determination width. The controller finishes the focusing operation without performing the focus detection again after completing the drive when the defocus amount is out a range of a second in-focus determination width, and performs the focus detection again after completing the drive when the defocus amount is out a range of the second in-focus determination width. The second in-focus determination width is set to be greater than the first in-focus determination width and be greater than or equal to a drive limit value.
