The substrate processing apparatus is provided with a gas-liquid mixing nozzle for generating a gas-liquid mixture by mixing a liquid and a pressurized gas, to discharge the gas-liquid mixture to a substrate at high speeds. In one embodiment, a portable storage device communicates with a first electronic device, and the portable storage device communicates with a second electronic device via a network. Next, data of a second frame predetermined to be displayed on the pixels at a second time later than the first time is determined.
