Provided is a driving support system that includes an image recognition unit that performs image recognition processing to recognize if a recognition object associated with any of the support processes is included in image data captured by an on-vehicle camera and a recognition area information storage unit that stores information regarding a set recognition area in the image data that is set depending on a recognition accuracy of the recognition object set for execution of the support process. A candidate process extraction unit is also included for extracting at least one execution candidate support process from the plurality of support processes and a support process execution management unit that allows execution of the extracted execution candidate support process on a condition that a position in the image data of the recognition object recognized by the image recognition processing is included in the set recognition area.
