Claim 15:
16. A method comprising:
obtaining, from an image sensor of an image capture apparatus, using a currently operative lens, wherein the currently operative lens is a primary lens or an alternate lens, wherein the primary lens is a lens other than a fisheye lens and the alternate lens is a fisheye lens, of the image capture apparatus and in accordance with a currently configured lens mode, wherein the currently configured lens mode is a primary lens mode or an alternate lens mode, a current input image, wherein obtaining the current input image includes obtaining, as the current input 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, generating the spatially reduced image includes cropping in accordance with the alternate lens mode; and
in response to obtaining the current input image, performing lens mode auto-detection by the image capture apparatus, wherein lens mode auto-detection includes:
obtaining predicate lens mode data;
obtaining probable lens mode data, wherein obtaining the probable lens mode data includes obtaining one or more lens mode detection metrics by analyzing the current image, wherein obtaining the lens mode detection metrics includes:
obtaining at least one of a corners mean value, a corners standard deviation value, or a center mean value;
obtaining the probable lens mode data includes:
obtaining one or more lens mode detection metrics by analyzing the current image; and
generating the probable lens mode data in accordance with the lens mode detection metrics;

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