Abstract

A DPF controller (21) generates, as image information, a layout identifier (MEN) that specifies the layout of an image to be displayed on a liquid crystal display device (11), and an element image identifier (SEN) that specifies the display mode of element images that are being subjected to layout. When an SEN is newly determined and the newly determined SEN is equal to a previously determined SEN, the newly determined SEN is not output to a drawing controller (22).

Claims

1. An image information generation device that receives state information collected from each part of a mobile object, generates image information for displaying an image in accordance with a situation of the mobile object on a dot matrix type display device, and outputs the image information to an image drawing processing device synthesizing an image to be displayed on the displayed device,

the image information containing a layout identifier for specifying a layout of the image to be displayed on the display device and an element image identifier for specifying a display mode of an element image in the layout,

the image information generation device comprising:

an identifier storage portion that stores an identifier table defining a correspondence relationship between the state information and the layout identifier, a correspondence relationship between the state information and the element image identifier, and a correspondence relationship between the layout identifier and the element image identifier;

an identifier determination portion that acquires state information collected from each part of the mobile object, and matches the acquired state information with the identifier table, thereby determining a layout identifier and an element image identifier in accordance with a situation of the mobile object at a time when the state information is collected; and

a display management information storage portion that temporarily stores the element image identifier determined by the identifier determination portion in a partial area containing the element image in the layout,

wherein, when the element image identifier is newly determined by the identifier determination portion and the newly determined element image identifier is the same as the previously determined element image identifier, the newly determined element image identifier is not output to the image drawing processing device.

2. The image information generation device according to claim 1, wherein the display management information storage portion includes an area for storing a completion flag indicating that the element image identifier determined by the identifier determination portion has been output to the image drawing processing device, and

when an element image identifier is newly determined by the identifier determination portion, and it is determined that the previously determined element image identifier has not been output to the image drawing processing device based on the completion flag, the newly determined element image identifier is discarded.

3. The image information generation device according to claim 1, wherein the display management information storage portion includes a queue area capable of storing a plurality of element image identifiers determined by the identifier determination portion, and an area for storing a completion flag indicating that the element image identifiers in the queue area have been output to the image drawing processing device, and

when an element image identifier is newly determined by the identifier determination portion, and it is determined that a previously determined element image identifier has not been output to the image drawing processing device based on the completion flag, the newly determined element image identifier is stored in the queue area.

4. The image information generation device according to claim 1, wherein the partial area is rectangular.

5. A display control device, comprising:

the image information generation device according to claim 1;

an image storage portion that stores a layout image corresponding to each layout identifier and an element image corresponding to each element image identifier; and

an image drawing processing device that acquires a layout identifier and an element image identifier output from the image information generation device, extracts a layout image corresponding to the layout identifier and an element image corresponding to the element image identifier from the image storage portion and synthesizes the layout image and the element image to generate an image to be displayed on the display device.

6. An information display system for a mobile object, comprising the display control device according to claim 5;

and

a display device that displays an image generated by the image drawing processing device of the display control device.

7. An information display system for a mobile object according to claim 6, wherein the display device is a liquid crystal display device.

8. A module for a driver seat to be attached around a driver seat of a mobile object, comprising the information display system for a mobile object according to claim 6.

9. A mobile object comprising the information display system for a mobile body according to claim 6, wherein the display device is attached to a position visibly recognizable at least from a driver seat.

10. The mobile object according to claim 9, wherein the mobile object is an automobile, and

the state information is sent from an ECU provided in each part of the automobile and collected to the image information generation device via an in-car network.
