Adaptive image sensor systems and methods

A method of operating an electronic device having first and second imaging sensors, the method comprising:

• operating the first imaging sensor in an active mode in which the first imaging sensor captures video of a scene;
• analyzing the captured video of the scene, wherein analyzing the captured video comprises detecting a predefined trigger criterion and detecting ambient light;
• and
• in response to detecting the predefined trigger criterion with the first imaging sensor, activating the second imaging sensor in the electronic device and capturing video, wherein activating the second imaging sensor and capturing video comprises utilizing information obtained from analyzing the captured video from the first imaging sensor to adjust operational parameters of the second imaging sensor, and wherein the information obtained from the analysis of the captured video comprises information describing the speed of at least one object in the scene.

A method, comprising:

• with at least one imaging sensor in an electronic device, imaging a scene at a first framerate;
• with the at least one imaging sensor, detecting a change in the scene;
• and
• after detecting the change in the scene, adjusting the framerate of the at least one imaging sensor to a second framerate based upon the detected change in the scene, wherein imaging the scene at the first framerate with the at least one imaging sensor comprises imaging the scene at the first framerate with a primary imaging sensor, wherein detecting the change in the scene with the at least one imaging sensor comprises detecting the change in the scene with a secondary imaging sensor, and wherein adjusting the framerate of the at least one imaging sensor to the second framerate based upon the detected change in the scene comprises adjusting the framerate of the primary imaging sensor to the second framerate based upon the detected change in the scene.
