The present invention provides an imaging device and a time-lapse imaging method capable of simply realizing time-lapse imaging using a pan and tilt mechanism. In a preferred aspect of the present invention, an imaging device includes a pan and tilt mechanism that rotates an imaging unit in a horizontal direction and a vertical direction relative to a device body, transmits a live view image to a smartphone, displays the live view image on a display and input unit, and receives an instruction input for specifying camerawork in time-lapse imaging using the display and input unit. Accordingly, the instruction input for specifying camerawork for performing time-lapse imaging using the pan and tilt mechanism can be simply input. The imaging device controls at least the pan and tilt mechanism based on the instruction input for specifying camerawork and controls the imaging unit to perform time-lapse imaging.
