  • Patent number: 10764469
    Abstract: An image processing apparatus includes an obtaining unit to obtain image data and a dynamic range conversion unit to convert an input luminance signal included in the image data into an output luminance signal for an image printing apparatus by using a conversion parameter. A dynamic range of luminance of the converted image data is narrower than that of the unconverted image data before the dynamic range conversion. When the input luminance signal indicates an input black reference luminance value, the output luminance signal indicates an output black reference luminance value, and, when the input luminance signal indicates a predetermined reference input luminance value, the output luminance signal indicates a reference output luminance value, the reference output luminance value being a value calculated based on the predetermined reference input luminance value and the output black reference luminance value for observing a print product to be printed by the printing apparatus.

  • Publication number: 20190276009
    Abstract: A control apparatus for a vehicle includes: a target yaw rate calculator; a primary limit yaw rate calculator; a yaw rate comparator; a secondary limit yaw rate calculator; and a vertical load controller. The target yaw rate calculator calculates a target yaw rate of the vehicle. The primary limit yaw rate calculator calculates a primary limit yaw rate on a basis of a vertical load on a wheel. The yaw rate comparator compares the target yaw rate with the primary limit yaw rate. The secondary limit yaw rate calculator calculates a secondary limit yaw rate in a case where a distribution of the vertical load on the wheel is changed in a case where the target yaw rate exceeds the primary limit yaw rate. The vertical load controller changes the vertical load on a basis of the secondary limit yaw rate.
