5. A display method for displaying a traveling image of a vehicle in a traveling direction on a display device, the traveling image being captured by a camera, the display method comprising:
calculating an estimated stop position indicating a stop position when braking is applied at a reference deceleration indicating a predetermined deceleration from a vehicle speed of the vehicle;
displaying the estimated stop position superimposed on the traveling image on the display device;
recognizing a stop line captured in the traveling image and calculating a position of the stop line; and
varying a display form of the estimated stop position and notifying by a buzzer sound, depending on whether the estimated stop position is before the position of the stop line or the estimated stop position is behind the position of the stop line,
wherein:
the reference deceleration includes a first reference deceleration, a second reference deceleration that is smaller than the first reference deceleration by a predetermined value, and a third reference deceleration that is variable between the first reference deceleration and the second reference deceleration;
the display method further includes
acquiring braking state information of the vehicle,
determining a start of braking of the vehicle based on the braking state information, and
gradually changing, from a time of the start of braking, the third reference deceleration to the first reference deceleration corresponding to an elapsed time or based on the braking state information, with the second reference deceleration as an initial value; and
the calculating the estimated stop position includes
calculating the estimated stop position based on the second reference deceleration until the time of the start of braking,
calculating the estimated stop position based on the third reference deceleration from the time of the start of braking until the third reference deceleration reaches the first reference deceleration, and
calculating the estimated stop position based on the first reference deceleration after the third reference deceleration reaches the first reference deceleration.
