Image monitoring method and system
First Claim
1. A method for verifying the accuracy of image data generated by a display processor from an initial set of input parameters, the method comprising:
- capturing image data at a correlator;
receiving at least one comparison location including a first symbology within the image data;
receiving a template representing a second symbology;
calculating a correlation value using the comparison location and the template;
comparing the correlation value to a threshold value; and
determining a match between the first symbology appearing in the comparison location and the symbology represented by the template if the correlation value exceeds the threshold value.

Abstract
A system for verifying the accuracy of an image generated by a display processor and rendering engine is disclosed. The system includes a correlator circuit. The correlator circuit is operable to capture image data produced by a rendering engine from a set of input data and determine a correlation value calculated using a comparison location within the image data and a template. The correlator is further operable to compare the correlation value against a threshold value to determine a match between the comparison location within the image data and the template. The system further includes a checking processor coupled to the correlator circuit. The checking processor is operable to receive data representative of the correlation from the correlator and is further operable to initiate a warning in the event of any error in the data representative of the correlation.
