Abstract
A method for controlling an image capturing device that is operated according to a startup signal includes: configuring an image sensor array of the image capturing device by a first context to output a high-resolution image with a relatively long exposure time to a post-device; switching the first context to a second context based on the high-resolution image and a wide convergence zone; configuring the image sensor array by the second context to output one or more low-resolution images with relatively short exposure times in order to update an exposure value based on the low-resolution images; and updating the exposure value based on a narrow convergence zone to configure the image sensor array.
