Classification: CPC H  G | IPC G  H

Claim 10:
11. A computing device comprising:
a support member;
a sensor mechanically coupled to the support member, the sensor comprising an image array of a plurality of pixel cells generating image information for respective regions in a field of view of the sensor;
a processor, operatively coupled to the sensor and configured to process image information from the sensor;
a patch trajectory computing engine coupled to the sensor, the patch trajectory computing engine configured to:
estimate a trajectory of a patch of pixels among the plurality of pixels with respect to coordinates of the image array, the estimating comprising:
constructing a model of an object's motion in a physical world and a model of the image array's motion with respect to the physical world; and
computing the trajectory based on the model of the object's motion within the physical world and the model of the image array's motion with respect to the physical world;

dynamically modify a portion of the plurality of pixel cells included in the patch based on information indicating a position of the patch among the plurality of pixels at a first time and information indicating the trajectory of the patch among the plurality of pixels subsequent to the first time; and
in a time period subsequent to the first time:
control the sensor to selectively provide, to the processor, image information from the portion of the plurality of pixel cells in the patch without providing image information from pixel cells of the plurality of pixel cells that are outside of the patch.
