A method of quickly generating a relationship table of distance to disparity of a camera includes a display displaying a plurality of predetermined pattern groups generated by a host, wherein each predetermined pattern group of the plurality of predetermined pattern groups corresponds to a predetermined distance, at least two image capture units included in the camera executing a disparity generation step on the each predetermined pattern group, and after the at least two image capture units execute the image capture step on the plurality of predetermined pattern groups, the host generating the relationship table according to a plurality of predetermined distances and disparities corresponding to the plurality of predetermined distances.
