In a liquid discharging method for discharging droplets from a plurality of droplet discharging portions of a liquid discharging head, an actual pattern is created to indicate the discharging states of the droplets from the liquid discharging portions, and information about a defective liquid discharging portion having discharging failure is obtained by checking the discharging states. According to the information, the defective liquid discharging portion is prohibited form discharging, and discharging of droplets from a liquid discharging portion near the defective liquid discharging portion is controlled to reduce the influence of discharging failure of the defective discharging portion, and to correct image information on a recording medium.
