  • Patent number: 9124868
    Abstract: A 3D encoding apparatus encodes an input image and generates and outputs a three dimensional stream including a basic stream and an extended stream including a plurality of image groups. A 3D encoding apparatus includes a setter that sets a specific delay value for each image group based on the a first delay value as a delay value of the basic stream and a second delay value as a delay value of the three dimensional stream. The setter sets the specific delay value to a value not more than smaller one of the first delay value and the second delay value. The first virtual buffer and the second virtual buffer perform the buffer simulation for n+1th image group based on information about the specific delay value of the nth image group set by the setter in the basic stream and three dimensional stream.

  • Publication number: 20150239463
    Abstract: An internal combustion engine of a hybrid drive vehicle includes an exhaust gas purification catalyst in an exhaust passage. An internal combustion engine control device is configured to continuously rotate the internal combustion engine for a predetermined time period after an engine start. The internal combustion engine control device prohibits a fuel-cut within the predetermined time period after the engine start, thereby suppressing the frequent repetition of the start and stop of the internal combustion engine due to an accelerator pedal operation and suppressing oxygen storage in the exhaust gas purification catalyst associated with the fuel-cut. As a result, exhaust gas purification performance at the time of restarting the internal combustion engine is ensured.

  • Patent number: 8934537
    Abstract: A video coding device includes a buffer simulation unit that calculates an occupation amount of a virtual buffer to be used for controlling a coding amount, by using, for each picture, (a) a code length of a code that is an intermediate result of compression coding and (b) a code length of a compressed code that is a final result of the compression coding. This means that, for a picture that has not yet processed by an arithmetic coding unit, an occupation amount of the virtual buffer is calculated by using a code length of codes provided from a binarization unit.

  • Publication number: 20140379239
    Abstract: An internal combustion engine 2 is started by being cranked by an electric motor. An internal combustion engine start control device performs a feedback-control of an intake air amount of the internal combustion engine to a target idle intake air amount, learns a feedback correction amount applied in a feedback control, and performs a learning control using a learnt value in parallel with the feedback control. An engine rotation speed is converged to a target idle rotation speed in an early stage by setting an allowable correction range of a feedback correction amount applied before a start of learning of the intake air amount wider than the allowable correction range of the feedback correction amount applied after the start of the learning of the intake air amount.
