Latency-reducing image generating system, device, and method
First Claim
1. A system for generating an image presented on a display unit, such system comprising:
- a navigation system; and
an image processing unit configured to;
receive first navigation data of a first time or second navigation data predicted to occur at a second time, wherethe first navigation data is representative of at least first aircraft position and a plurality of first attitude parameters,the second navigation data is representative of at least second aircraft position and a plurality of second attitude parameters, andthe first navigation data of the first time is used to determine second navigation data predicted to occur at the second time if the first navigation data of the first time is received;
receive third navigation data at the second time from the navigation system, wherethe third navigation data is representative of at least third aircraft position and a plurality of third attitude parameters;
compare the second navigation data predicted to occur at the second time with the third navigation data received at the second time;
receive an image data set generated as a function of the second navigation data and representative of an image of an outside scene;
select a subset of the image data set in response to the comparison; and
provide the subset of the image data set to a display system, wherebyan image represented in the subset of the image data set is presentable to at least one viewer.

Abstract
A present novel and non-trivial system, device, and method for reducing image generating latency of an image presented on a display unit are disclosed. An image processing unit (“IPU”) may receive the image data set; receive (1) first navigation data of a first time from which second navigation data of the second time is determined or (2) second navigation data of a second time; receive third navigation data of the second time; compare the second navigation data with the third navigation data; and select a subset of the image data set in response to the comparison. Differences arising from the comparison, if any, may be used in determining the location and/or rotation of a cropping frame that selects the subset and forms a cropped image which is then provided to a display system, whereby the image represented in the subset is presented to the viewer.
