Imaging device, imaging device control method, and control program

In the present invention, a video processing unit (5) generates a first video signal, and a video output unit (6) generates a second video signal. When in a first mode, an imaging unit (3) is exposed to light in a corresponding manner to each one-frame period of the second video signal, whereas when in a second mode, the imaging unit is exposed to light under different imaging conditions during multiple sections divided of the one-frame period of the second video signal. When in the first mode, the video processing unit (5) generates frames for the first video signal on the basis of imaging signals that are read in a corresponding manner to the exposures corresponding to the respective one-frame periods, whereas when in the second mode, the video processing unit generates frames for the first video signal on the basis of imaging signals that are read in a corresponding manner to the exposures during the respective sections. The video output unit (6) converts the second video signal into a signal format that i
