Abstract: In a vehicle control device for an autonomous driving vehicle that autonomously travels based on an operation command, a gesture image of a person around the autonomous driving vehicle is acquired, and a stored reference gesture image is collated with the acquired gesture image. At this time, when it is discriminated that the gesture of the person around the autonomous driving vehicle is a gesture requesting the autonomous driving vehicle to stop, it is determined whether a disaster has occurred. When it is determined that the disaster has occurred, the autonomous driving vehicle is caused to stop around the person requesting the autonomous driving vehicle to stop.

Abstract: This invention enhances gloss uniformity of a formed image surface by selectively using colorless inks according to dot layouts of colored inks. A dot-layout unit sets colored dot layouts for respective colors of colored ink data. A colorless-dot-layout unit sets a colorless dot layout for one colorless ink with reference to a colorless dot layout table according to the colored ink data. An image is formed according to the colored and colorless dot layouts. In the colorless dot layout table, when a specular glossiness calculated according to the colored dot layouts is high, the colorless dot layout is set to superpose a colorless ink having a low refractive index on a colored ink having a high refractive index. Conversely, when the specular glossiness is low, the colorless dot layout is set to superpose a colorless ink having a high refractive index on a colored ink having a low refractive index.

The number of scans when forming an image by scanning each head is set for each of the inks sorted. Mask data for controlling the number of operations is created.

Abstract: To generate a color separation table for an image forming apparatus which has relatively dark/light color materials with high/low relative densities, a gamut boundary for limiting the use of the relatively dark color material is set. One of relatively dark color materials is selected, and at least a grid point which satisfies a condition that the color material value of the selected relatively dark color material is nonzero and a color value to be reproduced based on color material values set to the grid point exists in a region brighter than the gamut boundary is determined. The color material value of the selected relatively dark color material set to the grid point which satisfies the condition is replaced by the color material value of the relatively light color material.
