摘要： In an image coding device and method for coding an image signal employing sub-band transforms, an inputted image signal is hierarchically divided into a plurality of frequency bands using sub-band transforms and a plurality of frequency band signals are generated, with each frequency band signal comprising sub-band transform coefficients. The sub-band transform coefficients of each frequency band signal are then coded using zero tree coding and run length coding in a more efficient manner than with related devices and methods.

摘要： The air-fuel ratio of an air-fuel mixture to be supplied to a combustion chamber is controlled in accordance with a feedback control mode or a lean control mode. In the feedback control mode, the air-fuel ratio is feedback-controlled to be maintained around the stoichiometric air-fuel ratio. In the lean control mode, the air-fuel ratio is controlled to be maintained at a leaner side of the stoichiometric air-fuel ratio. Ignition plugs are ignited at a first ignition timing which is comparatively advanced in the lean control mode and at a second ignition timing which is behind the first ignition timing in the feedback control mode.The ignition plugs are ignited at the second ignition timing for a predetermined period of time after switching from the lean control mode to the feedback control mode and at the first ignition timing for a predetermined period of time after switching from the feedback control mode to the lean control mode.
摘要翻译：根据反馈控制模式或精益控制模式来控制供给燃烧室的空气燃料混合物的空燃比。在反馈控制模式中，反馈控制空燃比维持在理论空燃比的周围。在倾斜控制模式中，将空燃比控制为保持在化学计量空燃比的较稀侧。在第一点火正时点燃点火塞，在第一点火正时，在倾斜控制模式和在反馈控制模式中的第一点火正时后面的第二点火正时相比较。在从倾斜控制模式切换到反馈控制模式之后，并且在从反馈控制模式切换到倾斜控制模式之后的预定时间段期间，在第二点火正时点火点火器预定的时间段控制模式。
