In an image processing device, the memory stores conversion characteristic information corresponding to respective recording portions of an image recording device that records an image at a recording medium while moving a recording unit, which is provided with a plurality of the recording portions arrayed in a first direction, relative to the recording medium in a second direction that is perpendicular to the first direction, the conversion characteristic information expressing conversion characteristics for converting image data in units of one pixel. The first processing unit performs conversion processing along the first direction, continuously converting respective sets of pixel data aligned in the second direction, using conversion characteristic information that corresponds to the recording portions. The second processing unit performs image processing in the order of processing by the first processing unit. The output unit outputs the image data to the image recording device as aligned in the first direction.

An ejection element driving device includes a signal selection section and a signal selection control section. The signal selection section selects a drive signal to be applied to each ejection element from among drive signals including a liquid droplet ejection signal for ejecting a liquid droplet from the ejection element and a viscosity increase suppression signal for suppressing increase in a viscosity of liquid to be ejected by each ejection element. The signal selection control section refers to a predetermined parameter for any of the ejection elements for which the liquid droplet ejection signal is not selected. The signal selection control section exercises control over whether or not the signal selection section selects the viscosity increase suppression signal for the ejection elements for which the liquid droplet ejection signal is not selected, at each ejection cycle.

A recording head driving device and driving method are disclosed. At an inkjet recording head, ejector groups, at which ejectors which respectively eject ink drops are disposed two-dimensionally, constitute units. The units are disposed, with respect to one direction, such that partial regions of end portions of ejector groups disposed at adjacent unit structures mutually overlap one another in a direction orthogonal to the one direction. Driving sections, which drive the ejector groups disposed at the corresponding unit structures on the basis of inputted print data, are provided so as to correspond to the units respectively. When the inkjet recording head is driven, print data, for driving the ejector group is inputted to each of the driving sections. The print data driving the ejector group includes only print data driving ejectors included in a mutually-overlapping region of an ejector group at the unit adjacent to that unit.
