  • Patent number: 11115670
    Abstract: The present invention relates to specification of a tile capable of being independently processed to process a certain area at high speed in encoding and decoding of tiles resulting from division of an image in hierarchical coding of the image. An image encoding apparatus that performs the hierarchical coding of an input image with multiple layers includes an acquiring unit and an encoding unit. The acquiring unit acquires a first image generated from the input image and a second image having resolution different from that of the first image. In the encoding of a first area in the first image acquired by the acquiring unit, the encoding unit performs the encoding using a second area existing at the relatively same position as that of the first area in the first image in the second image as a reference image.

  • Patent number: 10843681
    Abstract: A vehicle control apparatus selects one of a power-on control and a power-off control for execution of a shift-down action in a transmission of a vehicle, and implements the selected power-on or power-off control. When a running speed of the vehicle is not lower than a predetermined value, the control apparatus selects one of the power-on control and the power-off control, based on a target input torque that is to be inputted to the transmission. When the vehicle running speed is lower than the predetermined value, the control apparatus selects one of the power-on control and the power-off control, based on an actual input torque that is actually inputted to the transmission.
