A recording mode control circuit controls a first recording mode in which still image data having a first image size corresponding to the number of pixels of an image sensing element is generated and recorded and a second recording mode in which moving image data having a second image size smaller than the first image size is generated and recorded. By way of example, the magnetic induction device can comprise a substrate having trenches formed in a bottom layer of the substrate, and holes formed in the substrate between the trenches and an upper layer of the substrate. Additionally, the identified image is enhanced, utilizing a hyper-clarity transform.
