Automated presentation equipment testing
First Claim
1. Apparatus for monitoring a display device in a venue, the apparatus comprising:
- a processor coupled to the display device having a display screen and to a photo sensor that points away from the display screen to capture an image of at least a portion of the venue without capturing an image of the display screen the processor configured to;
cause the display device to display a test sequence of image frames on the display screen;
receive data representing light from the display screen captured by the photo sensor during display of the test sequence of image frames the data including data representing light reflected by the venue and not including an image of the display screen;
compare the received data to data associated with a calibration sequence of expected image frames to detect a mismatch between the received data and the data associated with the calibration sequence of expected image frames to identify an error in the displayed test sequence of image frames;
record the detected error; and
report the detected error to cause servicing of the display device.

Abstract
An apparatus that automatically monitors a display device includes a photo sensor configured to receive light from a display screen of the display device. The photo sensor provides signals representing detected light levels to a processor. The processor is coupled to the display device and is configured to cause the display device to present a test sequence including a plurality of images on the display screen. The processor is configured to capture data from the photo sensor during the presentation of the test sequence and to compare the captured data to an expected sequence corresponding to the test sequence displayed by a well-functioning display. The processor is further configured to report any mismatch between the captured data and the expected sequence as a possible malfunction of the display device.

10. A method for monitoring a display device in a venue comprises:
-
generating a display of a test sequence of image frames on a display screen; receiving data representing light from the display screen during display of the test sequence of image frames, the light being captured by a photo sensor that points away from the display screen to capture an image of at least a portion of the venue without capturing an image of the display screen, the data including data representing light reflected by the venue and not including an image of the display screen; comparing the received data to data associated with a calibration sequence of expected image frames to detect a mismatch between the received data and the data associated with the calibration sequence of expected image frames; recording the detected mismatch; and reporting the detected error to cause servicing of the display device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 20)

18. A non-transitory computer-readable medium, configured for use with a processor coupled to a display device that displays images on a display screen and to a photo sensor pointed away from the display screen to capture an image of the venue without capturing an image of the display screen, the computer readable medium including program instructions configured to configure the processor to:
-
cause the display device to display a test sequence of image frames on the display screen; receive, from the photo sensor pointed away from the display screen, data representing light from the display screen during display of the test sequence of image frames, the data including data representing light reflected by the venue and not including data representing an image of the display screen and not including an image of the display screen; compare the received data to data associated with a calibration sequence of expected image frames to detect a mismatch between the received data and data associated with the calibration sequence of expected image frames; record the detected mismatch; and report the detected error to cause servicing of the display device. - View Dependent Claims (21)
