  • Patent number: 11247658
    Abstract: A control apparatus for a vehicle provided, with a step-variable transmission, includes: a feedback control portion; an input torque resetting control portion; a target input torque setting portion operated upon an increase of the accelerator pedal operation amount in the process of the shift-down action in a power-off state of the vehicle, to restrict an amount of increase of the input torque target value with respect to an amount of increase of an operator-required input torque value, so as to keep the target value not larger than an upper limit value until termination of the input torque resetting control; and an actual input torque increasing portion operated upon the increase of the accelerator pedal operation amount prior to initiation of the inertia phase, to implement an input torque increasing control to control the input torque so as to be larger than the target value, prior to the inertia phase initiation.

  • Patent number: 11218714
    Abstract: An image decoding apparatus decodes a bit stream generated by coding an image and decodes coded data included in the bit stream and corresponding to a target block to be decoded in the image. The apparatus includes a first determining unit configured to determine whether the target block is prediction-coded or palette-coded; a second determining unit configured to determine whether or not a pixel in the target block is escape-coded if the first determining unit determines that the target block is palette-coded; and a first decoding unit configured to decode the target block by using a second quantization parameter different from a first quantization parameter if the second determining unit determines that the pixel is escape-coded. The first quantization parameter is used to decode the coded data in a case where the first determining unit determines that the target block is prediction-coded.

  • 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.
