摘要： A method determines a correction amount of an EGR valve opening degree. A basic correction amount map is generated indicating a correlation between rotating speed, load factor, and the correction amount, while the opening degree is maintained at a reference opening degree and the EGR rate is maintained at a target EGR rate, based on correction amounts obtained for mutually different individual combinations of the rotating speed and the load factor. Estimated values of the correction amounts not contained in the basic map are acquired by estimating the distribution of the amounts not in the basic map based on a distribution trend. An extended correction amount map is generated indicating a correlation between the estimated values of the rotating speed, the load factor, and the correction amount while the opening degree is maintained at a reference opening degree and the EGR rate is maintained at a target rate.

摘要： In a MOS solid-state imaging device, each of a plurality of pixel cells has a charge holding unit 305. In order to reset the signal charge accumulated in the charge holding unit 305 in each pixel cell in an n-th row, the reset pulse supplied to the gate electrode of the reset transistor is switched to the high potential level Hi. Under this state, the reference voltage source VDDCELL is switched to the low potential level Lo. In response, the reset pulse n temporarily drops toward Lo because of the coupling capacity 308. The reset pulse n is switched to Lo after its potential rises back to Hi.
