An imaging device includes: an optical system; an imaging element that continuously generates image data of an object; a position changing unit that changes a relative positional relationship between the optical system and the imaging element; a touch panel that detects a contact position thereon, and periodically outputs a position signal according to the contact position; a position controller that controls the position changing unit based on duration of maintaining the contact position to change the positional relationship; a trimming unit that generates pieces of trimming image data by sequentially cutting out an area including a touch position corresponding to the position signal from an image corresponding to the image data each time the positional relationship is changed; and a super-resolution processer that performs pixel interpolation using the pieces of trimming image data to generate super-resolution image data having a higher resolution than that of each trimming image data.
