  • Publication number: 20210092423
    Abstract: A video encoding device (2) includes a side information determination section (21) and a side information encoding section (22). The side information determination section (21) sets a quantization parameter for each macroblock in such a manner that a difference between quantization parameters for each pair of macroblocks with successive encoding orders is equal to one of n difference values, and transforms the difference into one of n indices with respect to each pair. The side information encoding section (22) generates a binary sequence having a length corresponding to the size of the absolute value of the index. The total of absolute values of the n indices is smaller than the total of absolute values of the n difference values.

  • Patent number: 10850396
    Abstract: A controller includes a storage unit that stores a configuration file in which a tool coordinate system including a coordinate axis extending in the restriction direction of a movement of a hand is set. The controller includes a determination unit that determines whether or not the origin of the tool coordinate system moves in the direction of the coordinate axis extending in the restriction direction. The controller includes a speed limiting unit that limits the motion speed of the robot. The speed limiting unit performs a speed reduction control for reducing the movement speed of the hand or a stop control for stopping the robot if the origin of the tool coordinate system moves in the direction of the coordinate axis extending in the restriction direction.

  • Patent number: 10807240
    Abstract: A robot control device is provided with a display unit for displaying a three-dimensional image of a jog coordinate system and a robot, and an input unit including keys corresponding to coordinate axes of the jog coordinate system. The input unit is formed so that an operator operates an image on the display unit. A display control unit changes the image so that the direction of the jog coordinate system is fixed while the direction of the robot changes in accordance with the operation of the operator in the input unit. When the operator pushes the key, a manual control unit changes the position and orientation of the robot based on the direction of the jog coordinate system with respect to the robot in the image.
