1. A method for testing a number of display devices, the method comprising:
- receiving images displayed on the number of display devices by a computer system for a platform during a performance of a number of tests at a number of test locations for the platform;
comparing the images to each other to form a comparison, wherein comparing comprises comparing only a number of areas in a first image in the images, the number of areas being less than an entirety of the first image, with a corresponding number of areas in a second image in the images, the corresponding number of areas being less than an entirety of the second image, and wherein the second image is subsequent to the first image;
determining whether any change between the number of areas in the first image and the corresponding number of areas in the second image is sufficient to identify the second image as an image of interest using the policy; and
responsive to a determination that the any change is sufficient, identifying the second image as the image of interest using the policy.

13. A method for testing a display device for an aircraft, the method comprising:
-
displaying information generated by a computer system for the aircraft on the display device; receiving first images from a number of cameras directed at the display device, wherein the first images comprise first timestamps for the first images; changing a parameter in the aircraft at a selected time; responsive to a change in the parameter in the aircraft, receiving second images from the number of cameras, wherein the second images comprise second timestamps for the second images; comparing the second images with corresponding first images to form a comparison, wherein comparing comprises comparing only a number of areas in a first image in the images, the number of areas being less than an entirety of the first image, with a corresponding number of areas in a second image in the images, the corresponding number of areas being less than an entirety of the second image, and wherein the second image is subsequent to the first image; and determining whether any change between the number of areas in the first image and the corresponding number of areas in the second image is sufficient to identify the second image as an image of interest using the policy; and responsive to a determination that the any change is sufficient, identifying the second image as the image of interest using the policy. - View Dependent Claims (14)

15. An apparatus comprising:
-
an image acquisition system configured to obtain images generated for display on a number of display devices for a platform during a performance of a number of tests at a number of test locations for the platform; and a computer system configured to receive the images from the image acquisition system; and
identify a portion of the images as a number of images of interest using a policy, wherein the computer system is further configured to display the number of images of interest on a display device and display a number of graphical indicators on the number of images of interest, wherein a graphical indicator displayed on an image of interest in the number of images of interest is associated with an area on the image of interest in which a change between the area on the image of interest and the area on an image in the images preceding the image of interest meets a number of criteria in the policy;wherein the computer system is further configured to identify the portion of the images by comparing only a number of areas in a first image in the images, the number of areas being less than an entirety of the first image, with a corresponding number of areas in a second image in the images, the corresponding number of areas being less than an entirety of the second image, and wherein the second image is subsequent to the first image; wherein the computer system is further configured to determine whether any change between the number of areas in the first image and the corresponding number of areas in the second image is sufficient to identify the second image of interest using the policy; and wherein the computer system is further configured to identify, responsive to a determination that the any change is sufficient, the second image as the image of interest using the policy. - View Dependent Claims (16, 17, 18)

19. An aircraft display system comprising:
-
a display system associated with an aircraft, wherein the display system comprises a number of display devices; an image acquisition system associated with the aircraft, wherein the image acquisition system is configured to obtain images generated for display on the display system associated with the aircraft during operation of the aircraft; and a testing module associated with the aircraft, wherein the testing module is configured to receive the images from the image acquisition system; wherein the testing module is further configured to identify a portion of the images by comparing only a number of areas in a first image in the images, the number of areas being less than an entirety of the first image, with a corresponding number of areas in a second image in the images, the corresponding number of areas being less than an entirety of the second image, and wherein the second image is subsequent to the first image; wherein the testing module is further configured to determine whether any change between the number of areas in the first image and the corresponding number of areas in the second image is sufficient to identify the second image as an image of interest using the policy; wherein the testing module is further configured to identify, responsive to a determination that the any change is sufficient, the second image as the image of interest using the policy; and wherein the testing module is further configured to display the image of interest on a display device. - View Dependent Claims (20, 21)
