Imaging systems with dynamic image sensor configuration adjustment

A sensor processor for an imaging system, the sensor processor comprising:

• a sensor controller operably couplable to event detection circuitry of the imaging system and to an ambient light monitor of the imaging system, wherein the sensor controller is configured, when coupled to the event detection circuitry and the ambient light monitor, to:
• receive one or more event signals from the event detection circuitry and an ambient light signal from the ambient light monitor,
• determine, based at least in part on the one or more event signals and the ambient light signal, an optimized value for a contrast threshold or another sensor setting of the event detection circuitry that is usable by the imaging system to improve an image quality of one or more images of an external scene, and
• communicate the optimized value to the event detection circuitry.

A method for operating an imaging system, the method comprising:

• generating, using photosensors of a plurality of pixels included in a pixel array, photocurrent in response to incident light received from an external scene;
• outputting, based at least in part on the photocurrent and a contrast threshold, one or more event signals, wherein each of the one or more event signals indicates an event detected in the external scene;
• generating an ambient light signal indicating an ambient light level of the external scene;
• determining, based at least in part on the one or more event signals and the ambient light signal, an optimized value for the contrast threshold or another sensor setting of the imaging system that is usable by the imaging system to improve an image quality of one or more images of the external scene;
• and
• communicating the optimized value to a component of the imaging system for adjustment of the contrast threshold or the other sensor setting.
