First Claim
1. A display control device comprising:
- an input signal processing section for processing an input signal;
a display section for displaying an image;
a first display control section for processing an output signal from the input signal processing section and outputting a first display signal to be displayed on the display section;
a second display control section operated by an operating system program, the second display control section for processing the first display signal from the first display control section and outputting a second display signal to be displayed on the display section; and

Abstract
A display control device is provided with an input signal processing section for processing an input signal, a display section for displaying an image, a first display control section for processing an output signal from the input signal processing section to be displayed on the display section, a second display control section operated by an operation program for OS, and a signal switching section for outputting the display signal from the second display control section on to the display section at the normal time. The second display control section processes an output signal from the first display control section to be displayed on the display section. The signal switching section outputs the display signal from the first display control section onto the display section when an abnormal condition of the second display control section is detected.

12. A display control device comprising:
-
an input signal processing section for processing an input signal representing a vehicle condition;
a display section for displaying an image;
a first display control section for processing an output signal from the input signal processing section and outputting a first display signal to be displayed on the display section;
a second display control section operated by an operating system program, the second display control section for processing the first display signal from the first display control section and outputting a second display signal to be displayed on the display section; and
a signal switching section for outputting the second display signal from the second display control section on to the display section at the normal time, the signal switching section for outputting the first display signal from the first display control section onto the display section when an abnormal condition of the second display control section is detected, wherein the first and second display signals comprise image data regarding the vehicle condition, and the image data of the display signal from the first display control section has a lower resolution than the image data of the display signal from the second display control section.
