1. A display system, comprising:
- an input to receive first image data, representing a first part of an image to be displayed on a display device, and second image data, representing a second part of the image to be displayed;
a display control unit coupled to the input to generate a third image data, based on the first and second image data, representing a combination of the first and second parts of the image, and to generate a display signal, based on the third image data, to be provided to the display device as the image to be; and
an image monitoring unit coupled to the input to receive the second image data and coupled to the display control unit to receive the third image data, the image monitoring unit to compare information based on the second image data with information based on the third image data to verify that the second part of the image to be displayed is represented in the third image data, wherein the information based on the second image data is not based on the third image data.

Abstract
A display controller includes a controller input connectable to receive first image data representing a non-safety relevant part of an image to be displayed on a display and to receive second image data representing a safety relevant part of the image. A merging unit is connected to the controller input, for composing the image from the first image data and second image data. A controller output is connectable to the display, for outputting display data representing the image. An image monitor is connected to the controller output, for comparing a part of the image corresponding to the safety relevant part with an reference for the part.

13. A method, comprising:
-
receiving at a display system first image data representing a first part of an image to be displayed on a display device; receiving at the display system second image data representing a second part of the image to be displayed; generating a third image data, based on the first image data and the second image data, representing a combination of the first and second parts of the image; transmitting a display signal based on the third image data for reception at a display device; and comparing information based on the second image data with information based on the third image data to verify that the second part of the image to be displayed is represented in the third image data, wherein the information based on the second image data is not based on the first image data. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
