Abstract

An on-vehicle instrument panel display system preferably is mounted on an automobile and operative such that a plurality of pieces of information including information relating to an automobile are converted into images and the images are displayed all on a liquid crystal panel. The on-vehicle instrument panel display system has a vehicle system, an amenity system, and a safety system, each of which creates data for displaying the images. Further, the on-vehicle instrument panel display system has an instrument panel image composition/output section which combines data created by the systems and outputs the result as composed image data to the liquid crystal panel. The instrument panel image composition/output section includes an image composition LSI. Composed image data outputted from the image composition LSI is an RBG signal or a YUV signal.

Claims

1. An on-vehicle instrument panel display system, mounted on an automobile, in which images including information relating to the automobile are displayed all on a display device, said system comprising:

a data generating section arranged to generate data for displaying the images; and

an image composing section arranged to combine the data generated by the data generating section so as to obtain composite image data, and output the composite image data to the display device;

wherein

the image composing section includes an image composition LSI (Large Scale Integration) by which the composite image data is outputted; and

the composite image data outputted by the image composition LSI is an RGB (red (R), green (G), and blue (B)) signal or a YUV (luminance (Y), difference between luminance and a red component (U), and difference between luminance and a blue component (V)) signal.

2. The on-vehicle instrument panel display system as set forth in claim 1, wherein the image composing section is arranged so as not to be affected by heat or vibrations generated in an engine of the automobile.

3. The on-vehicle instrument panel display system as set forth in claim 2, wherein the RGB signal or the YUV signal outputted by the image composition LSI is a serial RGB signal or a serial YUV signal, respectively.

4. The on-vehicle instrument panel display system as set forth in claim 1, wherein the image composing section is provided in a space, having a volume of not less than a predetermined volume, in the automobile.

5. The on-vehicle instrument panel display system as set forth in claim 4, wherein the RGB signal or the YUV signal outputted by the image composition LSI is a serial RGB signal or a serial YUV signal, respectively.

6. The on-vehicle instrument panel display system as set forth in claim 1, wherein the image composing section is arranged in the automobile such that the image composing section is positioned further from a front of the automobile than a navigation device which is provided in an interior of the automobile.

7. The on-vehicle instrument panel display system as set forth in claim 6, wherein the RGB signal or the YUV signal outputted by the image composition LSI is a serial RGB signal or a serial YUV signal, respectively.

8. The on-vehicle instrument panel display system as set forth in claim 1, wherein the RGB signal or the YUV signal outputted by the image composition LSI is a serial RGB signal or a serial YUV signal, respectively.

9. An image data output device that converts, into image data, a plurality of pieces of information including information relating to an automobile and outputs the image data to a display device mounted on the automobile, said image data output device comprising:

an image composing section arranged to combine the image data to be outputted to the display device;

the image composing section including an image composition LSI (Large Scale Integration) by which the combined image data is outputted; and

the composite image data outputted by the image composition LSI being an RGB (red (R), green (G), and blue (B)) signal or a YUV (luminance (Y), difference between luminance and a red component (U), and difference between luminance and a blue component (V)) signal.
