Abstract
A method includes obtaining, from an image sensor, one or more images that represent an object, and determining a speed of the object based on the one or more images. The method also includes determining that the speed of the object exceeds a threshold speed and, based on determining that the speed of the object exceeds the threshold speed, determining a region of interest (ROI) of the image sensor expected to represent the object. The method further includes causing the image sensor to generate one or more ROI images using the ROI.
Claims20
A method comprising:
- obtaining, from an image sensor, one or more images that represent an object;
- determining a speed of the object based on the one or more images;
- determining that the speed of the object exceeds a threshold speed;
- based on determining that the speed of the object exceeds the threshold speed, determining a region of interest (ROI) of the image sensor expected to represent the object;
- and
- causing the image sensor to generate, using the ROI, one or more ROI images at a first frame rate that is higher than a second frame rate at which the image sensor generated the one or more images.
A system configured to perform operations comprising:
- obtaining, from an image sensor, one or more images that represent an object;
- determining a speed of the object based on the one or more images;
- determining that the speed of the object exceeds a threshold speed;
- based on determining that the speed of the object exceeds the threshold speed, determining a region of interest (ROI) of the image sensor expected to represent the object;
- and
- causing the image sensor to generate, using the ROI, one or more ROI images at a first frame rate that is higher than a second frame rate at which the image sensor generated the one or more images.
A non-transitory computer-readable medium having stored thereon instructions that, when executed by a computing system, cause the computing system to perform operations comprising:
- obtaining, from an image sensor, one or more images that represent an object;
- determining a speed of the object based on the one or more images;
- determining that the speed of the object exceeds a threshold speed;
- based on determining that the speed of the object exceeds the threshold speed, determining a region of interest (ROI) of the image sensor expected to represent the object;
- and
- causing the image sensor to generate, using the ROI, one or more ROI images at a first frame rate that is higher than a second frame rate at which the image sensor generated the one or more images.
