An information processing device measures a position of the moving object, acquires success or failure information relating to success or failure of the position measurement, acquires at least one of histories, determines to interrupt driving control of the moving object, and decides, if the driving control of the moving object is determined to be interrupted, a restart method. The histories include a history of the position of the moving object, a driving history of the moving object, a history of illuminance around the moving object, and a history of a direction of an imaging element mounted in the moving object. The driving control of the moving object is interrupted on the basis of the success or failure information. The restart method restarts the driving control of the moving object on the basis of at least one of the histories.

In multipass printing, a mask pattern which increases the degree of dot dispersion in each pass is used for a combination of inks for increasing glossiness when printing an image. Contrary, a mask pattern which decreases the degree of dot dispersion in each pass is used for a combination of inks for decreasing glossiness. Thus, an entire image can be made uniformly glossy by suppressing gloss unevenness within the image.

In a high lightness region of a color hue corresponding to a basic color material, the high lightness region ranging from a lightness level corresponding to the maximum color saturation level that is reproducible by the basic color material to the highest lightness level, color separation data corresponding to the basic color material is generated. In an intermediate lightness region whose lightness level is lower than that of the high lightness region, color separation data corresponding to the basic color material and two color materials (one of them is preferably is a particular color material) that have color hues close to that of the basic color material is generated. This provides the advantage of enlarging the color gamut in the low lightness region of a basic color hue.
