  • Patent number: 11606479
    Abstract: An imaging processing system includes an image pickup device that has circuitry which creates, from raw image data, image data including a first gamut, and compression-codes the image data including the first gamut to generate compression-coded image data. The system also includes an image processing device that has circuitry which decodes the compression-coded image data to generate uncompressed image data, which includes the first gamut. The circuitry of the image processing device also converts the uncompressed image data including the first gamut into image data including a second gamut, where the first gamut encompasses the second gamut.

  • Patent number: 8249773
    Abstract: To provide a vehicle capable of performing a transition between a stable state and an inverted state with a simple structure. A vehicle in accordance with an aspect of the present invention is a vehicle that moves by inverted pendulum control, including a rider seat, a chassis, a right driving wheel, a left driving wheel, motors to rotationally drive the right driving wheel and the left driving wheel, a forward bar protruding forward beyond the chassis, a motor to rotational drive the forward bar, a footstep attached to the forward bar, and a control box to control the motor. The feet of a rider 80 are put on the footstep. The control box changes the vehicle to an inverted state by raising the footstep so that the footstep moves away from a ground, or changes the vehicle to a stable state by lowering the footstep so that the footstep comes into contact with the ground.

  • Patent number: 7697165
    Abstract: A gamut compressing device for compressing video data in a first gamut into video data in a second gamut. The device includes a compression unit compressing a value of color data in the first gamut, not contained in the second gamut, into a value of color data contained in the second gamut through a predetermined compression calculation. A gradation generating unit generates gradation such that a plurality of values of color data having the same value as a result of the compression become different in the second gamut.
