Abstract

A display control unit (20) includes an input (22) connectable to receive input image data representing an input image (24) comprising a first set (26) and a second set (28) of image elements. The second set of image elements includes security related information. The display control unit further comprises: an output (30) connectable to provide output image data representing an output image (32) comprising at least said security-related information; an image enhancement module (34), when a security mode signal (36) said image enhancement module (34) is arranged to perform an image enhancement process for said first set of image elements when indicating a first mode; and a verification module (38) when said security mode signal indicates a second mode , the verification module (38) is arranged to perform a verification process for the second set of image elements.

Description

technical field [0001] The present invention relates to a display control unit, an image display system and a method for outputting image data. Background technique [0002] Information and entertainment systems and consumer entertainment devices may employ complex graphics schemes to provide users with high-quality images or video. [0003] Today, the system can be used in environments where there are multiple sources of visual information available. For example, in a vehicle, a display can be used to provide both entertainment, video or navigation information or any other non-safety relevant information, as well as safety relevant information, such as the speed of the vehicle and the temperature of the engine, at the same time. [0004] Image enhancement methods can be applied to image data to be displayed, especially when processing digital image data, for improving image quality, reducing noise or visibility errors. The same or similar enhancement methods can be used t...
