Abstract
A imaging device includes an imaging element; a memory unit configured to temporarily store pieces of image data captured individually at predetermined timings via the imaging element; a comparator configured to compare the image data recorded in the memory unit to detect whether an image change greater than or equal to a first threshold has occurred; a determining unit configured to determine whether the image change has converged to an amount less than or equal to a second threshold by comparing the image data recorded in the memory unit when an image change greater than or equal to the first threshold has been detected; and a controller configured to exercise control so that image data captured via the imaging element is recorded on a predetermined recording medium when it is determined that the image change has converged to an amount less than or equal to the second threshold.
