IMAGE DATA GENERATOR, LEAN VEHICLE, AND IMAGE DATA GENERATION METHOD

An image data generator is for an assistance system. The assistance assists a driver with driving a lean vehicle. The image data generator can suppress a delay in initiation of rider assistance operation in an assistance system in comparison with conventional assistance systems. The image data generator has an input section, a first data generating section, and a second data generating section. The input section receives an imaging data from an imaging device. The imaging device detects an environment around the lean vehicle. The first data generating section generates a first image data by shifting the imaging data in a vertical direction. The second data generating section generates a second image data by rotating the first image data.
