An image processing apparatus includes an event acquisition unit that acquires a pen event based on an operation on a screen; a drawing-click determining unit that determines whether the pen event is an event concerning a stroke of a dot image or concerning a click operation; and a countdown timer that starts clocking when the drawing-click determining unit receives a determination-target pen event to determine, wherein the drawing-click determining unit determines that the determination-target pen event is an event concerning a stroke of a dot image when the clocking has ended and the event acquisition unit has acquired a pen event concerning another stroke, or when an elapsed time from an end of a pen event concerning another stroke acquired prior to the determination-target pen event is within a certain period of time.

A liquid discharging apparatus includes: a head having nozzles; and a controller. The controller executes: a first recording processing of discharging liquid from the nozzles with respect to a first area of a recording medium, based on first image data, and a second recording processing of discharging the liquid from the nozzles with respect to a second area, of the recording medium, which overlaps with or is adjacent to the first area based on second image data, after a predetermined time has elapsed since the first recording processing. The controller further executes a determining processing of determining the predetermined time based on color information of the first image data.

A microelectromechanical device includes a body of semiconductor material, which forms a cavity, a mobile structure, and an actuation structure. The actuation structure includes at least one first deformable element which faces the cavity and is mechanically coupled to the body and to the mobile structure, and a piezoelectric-actuation system which can be controlled so as to deform the first deformable element and cause a consequent rotation of the mobile structure. The mobile structure includes a supporting region and at least one first pillar region, the first pillar region being mechanically coupled to the first deformable element, the supporting region being set on the first pillar region and overlying at least part of the first deformable element.
