IMAGING DEVICE, IMAGING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

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.

1. An imaging device comprising:
an optical system configured to image an object; an imaging element configured to receive light of an object image of the object formed by the optical system and to continuously generate image data of the object; a position changing unit configured to change a relative positional relationship between the optical system and the imaging element relative to a surface orthogonal to an optical axis of the optical system; a display unit configured to display an image corresponding to the image data generated by the imaging element; a touch panel that is provided so as to overlap on a display area of the display unit and is configured to detect a contact position where an external body touches the touch panel and to periodically output a position signal according to the contact position; a position controller configured to control the position changing unit based on a period of time during which the contact position is maintained, and thereby to change the relative positional relationship between the optical system and the imaging element per a predetermined distance; a trimming unit configured to generate a plurality of pieces of trimming image data by sequentially cutting out an area including a touch position corresponding to the position signal from the image corresponding to the image data sequentially generated by the imaging element each time the relative positional relationship between the optical system and the imaging element is changed; and a super-resolution processer configured to perform pixel interpolation using the plurality of pieces of trimming image data sequentially generated by the trimming unit, and thereby to generate super-resolution image data having a higher resolution than a resolution of each trimming image data.
