Claim Text:
1. A liquid ejecting device, comprising: an ejecting unit provided with an electro-thermal conversion element and configured to eject a liquid to a medium by applying electric energy to the electro-thermal conversion element; a determining unit configured to determine whether a region of the medium to which the liquid is ejected by the ejecting unit is a first region or a second region with a number of ejections per unit area smaller than that of the first region; and a control unit configured to control ejection by the ejecting unit by changing magnitude of the electric energy to be applied to the electro-thermal conversion element, wherein the control unit makes the electric energy to be applied to the electro-thermal conversion element relatively larger for the ejection to the region determined by the determining unit to be the first region and makes the electric energy to be applied to the electro-thermal conversion element relatively smaller for the ejection to the region determined by the determining unit to be the second region, and wherein the electric energy to be applied to the electro-thermal conversion element is applied with a pulse-shaped waveform, and the control unit executes control by changing the magnitude of the electric energy by changing a width of the pulse-shaped waveform.
