Abstract: In an image information generation device, based on status information representing statuses of various sections of a mobile unit such as a motor vehicle, image information used to display an image required, for instance, for steering this mobile unit on a display device is generated easily. In order to generate, as the image information, a layout identifier that specifies a layout of an image to be displayed on the liquid crystal display device and a component image identifier that specifies a display mode of each component image in the layout, the DPF controller compares the MEN/SEN judging table that stores an identifier table in which a correlation between the status information and the MEN, a correlation between the status information and the SEN, and a correlation between the MEN and the SEN are defined with the status information collected from the ECUs in the various sections of the mobile unit.

Abstract: A DPF-ECU (1) includes a DPF controller (11) that generates a display identifier for displaying an information image in accordance with the situation of a mobile object on a liquid crystal display device (4) based on the state information acquired from the respective ECUs (3a) to (3d), a drawing controller (13) that generates a layout image showing a layout of the information image and an element image showing at least one of the state of each part of the mobile object based on the display identifier and causes the liquid crystal display device (4) to display the information image, and a write controller (17) that writes the display identifier in a log information storage part (18) as log information together with time information every time the displayed information image changes.

Abstract: A DPF controller (21) easily generates a display identifier and a speech identifier for providing an image and a speech required for driving a mobile body such as an automobile, etc. from state information representing the state of each part of the mobile body.

Abstract: In one embodiment of the present invention, a layout switching device includes: a disregard list storage section for storing, for each of display layouts, a disregard list indicating a type of state information which can be disregarded even when the state information is changed; and a disregard list comparing section for judging, in a case where the state information is changed, whether or not a type of the changed state information is indicated in the disregard list by referring to a disregard list which corresponds to a current display layout and is stored in the disregard list storage section. Further, a layout decision section decides a layout after switching, based on the latest state information and a layout decision rule, only in a case where the disregard list comparing section judges that the type of the changed state information is not included in the disregard list.
