Classification: CPC H  G | IPC G  H

Claim 10:
11. An image capture apparatus comprising:
a currently operative lens, wherein the currently operative lens is a primary lens, which is a lens other than a fisheye lens, or an alternate lens, which is a fisheye lens;
an image sensor configured to capture, using the currently operative lens, a current input image, wherein, to obtain the current input image, the processor executes the instructions to obtain the current input image in accordance with a currently configured lens mode, wherein the currently configured lens mode is a primary lens mode or an alternate lens mode; and
a processor configured to execute instructions stored in a memory of the image capture apparatus to perform lens mode auto-detection, wherein to perform lens mode auto-detection the processor executes the instructions to:
obtain predicate lens mode data;
obtain probable lens mode data using the current input image, wherein to obtain the probable lens mode data, the processor executes the instructions to:
obtain, as a current image, a spatially reduced image representative of the current input image, wherein, on a condition that the currently configured lens mode is the alternate lens mode, to generate the spatially reduced image the processor executes the instructions to crop the current input image in accordance with the alternate lens mode;
obtain one or more lens mode detection metrics by analyzing the current image; and
generate the probable lens mode data in accordance with the lens mode detection metrics;

obtain a lens mode score in accordance with the predicate lens mode data and the probable lens mode data;
determine whether the lens mode score is greater than a defined lens mode change threshold; and
in response to a determination that the lens mode score breaches the defined lens mode change threshold, output, for presentation to a user of the image capture apparatus, lens mode data indicating that the currently operative lens and a currently configured lens mode are mismatched.
