Abstract: A control device serving as a display control device includes a positional information acquisition unit, a determination unit that, based on positional information and speed information, determines whether a time required to travel from the current position of a vehicle to a guide point where the next leading guide is made on a route to a destination that the vehicle travels is equal to or more than a threshold time or whether the current position of the vehicle is within an area of a given distance from the guide point where the next leading guide is made; a display controller that changes a display mode of a display screen based on a result of the determining; and a line-of-sight operation receiver that receives an operation performed using a line of sight of a person on board on the display screen, wherein the display mode includes a first mode in which music information on music that is being reproduced in the vehicle is displayed and a second mode that is different from the first mode and in which inform

Abstract: A print control apparatus includes a print request receiving unit and a print control unit. The print request receiving unit receives a print request, including print target information, to a print apparatus. If a condition is satisfied under which print target information should have information regarding security added thereto for printing, the print control unit adds the information regarding security to the print target information and causes the print apparatus to print the print target information to which the information regarding security is added. If the condition is not satisfied, the print control apparatus stores the print target information included in the print request in a storage unit, and when an operation receiving unit provided in the print apparatus is operated to instruct to print the stored print target information, the print control apparatus causes the print apparatus to print the stored print target information.

Abstract: An image processing device includes a judgement section and a generation section. A latent image, which would be retained or eliminated by photocopying, is to be superposed with machine-readable code images, which are encoded supplementary information, to generate a superposed image. The judgement section judges overlapping of the latent image with the machine-readable code images. The generation section, on the basis of judgement results from the judgement section, determines an arrangement of the machine-readable code images and generates the superposed image.

Abstract: A document management device, which includes: a document receptor that receives a document; a pattern information generator that generates first information on which a first background pattern image is based; an addition section that adds the first information to the document; a setter that sets, to the document, a prohibition on editing the first information; a document storage that stores the document having the first information added thereto; a printing request receptor that receives a printing request; an prohibition lifting section that lifts the prohibition; an edition section that edits the first information to make second information on which a second background pattern image is based; a printing image generator that generates a printing image having the second background pattern image incorporated thereinto; and a sender that sends, to an image formation device, the printing image having the second background pattern image incorporated thereinto.
