Abstract: Disruptions in the continuity of image frames output from an image capture device due to switching from one image sensor to another image sensor of the device may be reduced or eliminated through controlled timing for switching of the image sensors according to a predefined image sensor configuration. Operation of a multi-sensor image device according to the predefined image sensor configuration may include an appropriate selection of a source for image adjustment during the zoom level transition. The predefined image sensor configuration may define transition parameters for particular zoom ranges of the image capture device.

Abstract: This disclosure provides devices, methods, computer-readable medium, and means for spatial alignment transform. In some aspects, a device may perform operations including capturing a first image of a scene using a first sensor at a first zoom ratio, capturing a second image of the scene using a second sensor at a second zoom ratio, the first image having a different field-of-view (FOV) than the second image, determining a translation matrix based on one or more spatial misalignments between the first image and the second image, determining a confidence associated with the translation matrix, in response to the confidence being greater than a confidence threshold, determining a weighting factor based on the first zoom ratio, the second zoom ratio, and a current zoom ratio of the device, applying the weighting factor to the translation matrix, and warping the first image to the second image using the weighted translation matrix.
