An imaging system (1) includes: plural imaging devices (11) which are mounted on the same moving body, and configured to capture subjects to acquire images; and a controller (12) configured to calculate a target white balance value common to the images acquired by the imaging devices. Each imaging device (11) includes: a white balance calculator (1082) configured to calculate an individual white balance value of the image acquired by the imaging device (11); and a white balance corrector (107) configured to correct the individual white value of the image of the subject taken by the imaging device (11) to the target white balance value. The controller (12) includes a weighting unit (2005) configured to individually weight the individual white balance value given from each imaging device (11).
