A scroll control method for aiding works including displaying a partial area of an image of an observation object on a display apparatus and moving a display area within the image to observe the image includes, by a computer, a first calculation step, a second calculation step, and a display control step. The first calculation step calculates a first direction of movement and first movement speed based on information on time and coordinates on a movement selected with a pointing device and instructed to operate. The second calculation step calculates a second direction of movement and a second movement speed from the first direction of movement and first movement speed. The display control step performs scroll control over the display area based on the second direction of movement and movement speed.
