摘要： A period of time from a point in time at which pilot injection is executed until an equivalence ratio in fuel spray, after exceeding a combustible equivalence ratio, falls below the combustible equivalence ratio is calculated as a physical ignition delay period. A chemical ignition delay period is calculated from the temperature and pressure inside a combustion chamber at a point in time at which the equivalence ratio in the fuel spray reached the combustible equivalence ratio. A total ignition delay period is calculated from the above-calculated ignition delay periods. The oxygen concentration and temperature inside the combustion chamber are adjusted such that the total ignition delay period matches a target ignition delay period.

摘要： A system provides an image displaying technique that provides stable high contrast even in an area having high brightness. Based on information about an average brightness level of a digital luminance signal, black-correction processing which decreases a brightness level by offsetting the brightness level to the minus side, and increase processing which increases a contrast gain within a dynamic range, are performed for an analog luminance signal or a digital luminance signal, enabling improvement in contrast even where brightness is intense.
