1. A liquid discharge apparatus comprising:
a head having multiple nozzles and configured to discharge a liquid from each of the multiple nozzles to an object in a flight direction to form a film on a surface of the object;
a driver configured to move at least one of the head or the object relative to other of the head or the object; and
circuitry configured to:
determine an amount of the liquid discharged from each of the multiple nozzles based on a flight angle between the flight direction and a normal direction of the surface of the object for each of the multiple nozzles; and
cause the head to discharge the liquid from each of the multiple nozzles for the amount of the liquid determined for each of the multiple nozzles, wherein the head includes a plurality of valves, each of the valves being configured to individually open and close a corresponding one of the multiple nozzles to discharge the liquid to the object from the corresponding one of the multiple nozzles, and the amount of the liquid discharged from each of the multiple nozzles is adjusted by changing a length of a liquid discharge period for discharging the liquid.
