Abstract

An instrument panel display system displays vehicle information, amenity information, and safety information as images. In this instrument panel display system, data (image data, image layout data, and image output control data) for displaying the images are generated in a shared manner by a vehicle system processor, an amenity system processor, and a safety system processor. On account of this, the stability of image display on an instrument panel of a vehicle or the like is improved and hence safety of driving is increased.
