  • Patent number: 8625178
    Abstract: An image forming apparatus includes an obtaining unit, an image forming section, and a controller. The obtaining unit obtains color signals containing color components the number of which is n, n being a natural number. The image forming section forms an image on a medium, the image being based on the color signals obtained by the obtaining unit. The controller performs control so that colors in a color gamut that is not reproduced if area coverage modulation, not density modulation, is used for expression are included in the image by expressing densities of the n color components contained in the color signals obtained by the obtaining unit by using density modulation and area coverage modulation.

  • Patent number: 8527152
    Abstract: A vehicle control device has first and second transmission circuits that communicate by radio with a portable unit and also has a control section that, when the portable unit is confirmed to be correct, engages in a permission mode that permits the start of an engine. The first and second transmission circuits transmit first and second request signals from first and second transmission antennas to first and second communicatable areas respectively. When a back door is detected to be open, the control section does not permit the start of the engine even if an ID code signal is returned from the portable unit in response to the second request signal.
