PROBLEM TO BE SOLVED: To provide an electronic endoscope capable of adjusting the white balance of two imaging devices at once, and to provide a white balance adjustment method, an electronic endoscope system and a white balance adjustment tool.SOLUTION: The electronic endoscope 10 includes: a first imaging part 12 provided on an insertion part distal end 11a; a second imaging part 13 provided on an insertion part side face 11b; and a memory for storing a difference between the gain value of video signals after white balance adjustment of the first imaging part 12 upon shipping and the gain value of video signals after white balance adjustment of the second imaging part 13, as a correction value for the white balance during observation. The white balance adjustment jig 50 includes: a bottom part 51 facing the first imaging part 12; and a wall part (projection part) 52a facing the second imaging part 13. During the observation, a difference between the gain value of the video signals after the white balance adjustment of the first imaging part 12 and the correction value stored in the memory is used as the gain value of the video signals of the second imaging part 13. |
