A multiview imaging part includes a plurality of imaging units. An exposure setting section individually sets an exposure value in each of the plurality of imaging units. The exposure setting section sets, in each of the imaging units, an individual reference exposure value and relative exposure values. The relative exposure values are obtained by changing the reference exposure value in a given number of steps in such a manner that the relative exposure values are centered around the reference exposure value. A panoramic image storage section stores captured images having different exposure values captured by the imaging units whose exposure values have been set by the exposure setting section. An HDR synthesis section synthesizes the captured images having different exposure values so as to generate a captured image having an adjusted dynamic range.
