Abstract

An image processing device includes multiple image data paths of the same configuration and a test circuit. The test circuit may test the image data paths with a first setting set on each of the image data paths. The test circuit may further test the image data paths in a second state with a second setting set on each of the image data paths. The testing of the image data paths may be based on a comparison of the outputs of the image data paths. One of the image data paths processes a first image data stream with the first setting to provide a first processed image data stream to a first display device, and another of the image data paths processes a second image data stream with the second setting to provide a second processed image data stream to a second display device.

Dependent claims

An image processing device, comprising:

a plurality of image data paths of the same configuration, wherein the plurality of image data paths comprise a first image data path and a second image data path;
and
a test circuit configured to:
test the plurality of image data paths in a first state in which a first setting is set on each of the plurality of image data paths, wherein the testing of the plurality of image data paths in the first state is based on a comparison of respective outputs of the plurality of image data paths;
and
test the plurality of image data paths in a second state in which a second setting is set on each of the plurality of image data paths, wherein the testing of the plurality of image data paths in the second state is based on a comparison of respective outputs of the plurality of image data paths,
wherein the first image data path is configured to process a first image data stream with the first setting to provide a first processed image data stream to a first display device during a display operation;
and
wherein the second image data path is configured to process a second image data stream with the second setting to provide a second processed image data stream to a second display device during the display operation.

A display system, comprising:

a plurality of display devices comprising a first display device and a second display device;
and
an image processing device comprising a plurality of image data paths of the same configuration, wherein the plurality of image data paths comprise a first image data path and a second image data path,
wherein the image processing device is configured to:
test the plurality of image data paths in a first state in which a first setting is set on each of the plurality of image data paths, wherein the testing of the plurality of image data paths in the first state is based on a comparison of respective outputs of the plurality of image data paths;
and
test the plurality of image data paths in a second state in which a second setting is set on each of the plurality of image data paths, wherein the testing of the plurality of image data paths in the second state is based on a comparison of respective outputs of the plurality of image data paths,
wherein the first image data path is configured to process a first image data stream with the first setting to provide a first processed image data stream to the first display device during a display operation;
and
wherein the second image data path is configured to process a second image data stream with the second setting to provide a second processed image data stream to the second display device during the display operation.

7 more elements

A method, comprising:

first testing a plurality of image data paths of the same configuration in a first state in which a first setting is set on each of the plurality of image data paths, wherein the first testing is based on a comparison of respective outputs of the plurality of image data paths;
second testing the plurality of image data paths in a second state in which a second setting is set on each of the plurality of image data paths, wherein the second testing is based on a comparison of respective outputs of the plurality of image data paths;
processing, by a first image processing circuit of the plurality of image data paths, a first image data stream with the first setting set on the first image data path to provide a first processed image data stream to a first display device during a display operation;
and
processing, by a second image data path of the plurality of image data paths, a second image data stream with the second setting set on the second image data path to provide a second processed image data stream to a second display device during the display operation.
