Abstract
Various examples are directed to systems and methods for selecting image sensors in a multiple image sensor device. A control circuit may receive a first frame from the first image sensor and a second frame from the second image sensor. The control circuit may receive object data describing an object depicted in the first frame and may turn off the second image sensor.

A system for processing image sensor frames, comprising:
- a panoramic camera comprising:
- a first image sensor having a first field-of-view;
- a second image sensor having a second field-of-view that partially overlaps the first field-of-view;
- and
- a control circuit comprising a control circuit processor and associated control circuit memory, wherein the control circuit is programmed to:
- receive a first frame from the first image sensor, the first frame comprising a first plurality of pixel values and first spatial data describing a two-dimensional arrangement of the first plurality of pixel values;
- receive a second frame from the second image sensor, the second frame comprising a second plurality of pixel values and second spatial data describing a two-dimensional arrangement of the second plurality of pixel values;
- stitch the first frame and the second frame to form a first panoramic frame, wherein the first panoramic frame comprises a third plurality of pixel values and third spatial data describing a two-dimensional arrangement of the third plurality of pixel values;
- receive object data describing an object depicted in the first panoramic frame, wherein the object data comprises an object set of pixel values from the third plurality of pixel values that are contiguous in the two-dimensional arrangement of the third plurality of pixel values;
- identify a second frame object set of pixel values from the second frame that depict the object;
- turn off the first image sensor;
- and
- generate a second panoramic frame, wherein the second panoramic frame comprises first image data captured by the second image sensor and omits any image data from the first image sensor.

A camera, comprising:
- a first image sensor having a first field-of-view;
- a second image sensor having a second field-of-view that partially overlaps the first field-of-view;
- and
- a control circuit comprising a control circuit processor and associated control circuit memory, wherein the control circuit is programmed to:
- receive a first frame from the first image sensor, wherein the first frame comprises a first plurality of pixel values and first spatial data describing a two-dimensional arrangement of the first plurality of pixel values;
- receive a second frame from the second image sensor, wherein the second frame comprises a second plurality of pixel values and second spatial data describing a two-dimensional arrangement of the second plurality of pixel values;
- combine the first frame and the second frame to generate a first output frame of the camera;
- receive object data describing an object depicted in the first frame, wherein the object data comprises an object set of pixel values from the first plurality of pixel values that are contiguous in the two-dimensional arrangement of the first plurality of pixel values;
- and
- generate a second output frame of the camera omitting data from the second image sensor after the second frame and including data from the first image sensor captured after the first frame, wherein the data from the second image sensor after the second frame is omitted from the second output frame based at least in part on omission of the object data from the second frame.
