Patent ID: 7222927

Claim:
A liquid discharge device comprises: a head wherein deviation of the discharge direction of a liquid droplet, discharged from a liquid discharge portion having a nozzle, can be controlled so as to be selected from a plurality of directions along a predetermined direction, wherein said liquid discharge portion comprises: a liquid chamber for storing liquid which is to be discharged; and a plurality of energy generating devices for generating energy for discharging said liquid stored within said liquid chamber from said nozzle; wherein said plurality of energy generating devices are arrayed within said liquid chamber in said predetermined direction; a discharge control circuit controls the discharge direction of a liquid droplet discharged from said nozzle by controlling the difference in energy occurring between at least two of said plurality of energy generating devices within said liquid chamber, and wherein a plurality of liquid droplets are discharged so as to land on each pixel region for forming a pixel corresponding to said pixel region, and wherein a target landing position of a liquid droplet which is to be discharged on each pixel region is determined at random, and wherein the discharge direction of said liquid droplet which is to be discharged from said liquid discharge portion is controlled such that said liquid droplet lands at said determined target landing position.
