Abstract: A detection area is set in a three-dimensional space in which a subject exists. When an actual hand enters the detection area, coordinate points (white and black dots) represented by pixels making up a silhouette of the hand in a depth image enter the detection area. In the detection area, a reference vector is set that shows the direction which the hand should face relative to the shoulder as a reference point. Then, an inner product between two vectors, a vector from the reference point to each of coordinate points and the reference vector, is calculated, followed by comparison between the inner products. Positions of coordinate points whose inner products are ranked high are acquired as the position of tips of the hand.

Abstract: A white-plate graphic erosion process is performed on print data subjected to a RIP process in the following procedure. First, an erosion candidate region which is a candidate for a region in which a white-plate graphic is eroded is determined. Then, a region to be applied with an ink of a color other than white is determined. Then, an application target region is determined. Then, a region other than a region obtained by an erosion process out of the application target region is determined to be an erosion allowed region. Then, a region included in the colored region and the erosion allowed region out of the erosion candidate region is determined to be an erosion target region. Finally, the values of data of pixels included in the erosion target region among white-plate data are rewritten such that the amount of white ink applied to the pixels is reduced.

Abstract: A black figure specification part of a data processing apparatus specifies a black figure from among a plurality of figures in original image data that represents each figure in a vector format. When the overprint attribute of the black figure is ON, a data processing part adds a new black figure whose overprint attribute is OFF and that indicates a figure central portion of the black figure excluding an outer edge portion of a predetermined width from the edge, to the original image data. When the black figure overlaps with another figure that includes a color other than black, the density of the other color in the area where the figure central portion and the other figure overlap each other is zero in raster data for image recording. This increases the darkness of color of the black figure and reduces the appearance of white streaks around the black figure.

The superimposing part generates data that includes an instruction to record a combined figure obtained by superimposing the thinned figure and the central line one above the other. Superimposing the thinned figure and the central line enables the target figure to be thinned without line becoming broken. The shape of a rasterized figure can be approximated to the shape of a figure indicated by original data.

First, an erosion candidate region which is a candidate for a region in which a white-plate graphic is eroded is determined. Then, a region to be applied with an ink of a color other than white is determined. Then, an application target region is determined.

Finally, the values of data of pixels included in the erosion target region among white-plate data are rewritten such that the amount of white ink applied to the pixels is reduced.
