摘要： Disclosed is an image display technique for displaying a high-quality image by an image signal of appropriate color saturation. To this end, in the invention, color histogram information is detected from a color difference signal and average brightness information or brightness histogram information from a brightness signal. Based on the detected color histogram information and average brightness information or brightness histogram information, the demodulation axis of a color difference signal is adjusted, thereby controlling the color saturation (chroma) of an image. This enables display of an image having color intensity suited to the brightness and chroma of an image signal.

摘要： The present invention provides a technique for performing gamma correction processing when there are a plurality of characteristic areas, each of which is characterized by the high frequency in a luminance histogram to improve the impression of contrast. According to the present invention, a luminance characteristic detector (4) detects the luminance of an input image signal and a microcomputer (5) calculates an APL and a luminance histogram of an input image signal. A gamma correction circuit (6) performs the gamma correction processing in response to the luminosity of the input image signal by use of the result of the calculation carried out by the microcomputer (5). Then, if there are a plurality of characteristic areas, each of which is characterized by the high frequency in the luminance histogram, a characteristic emphasis circuit (7) performs grayscale extension processing for the plurality of characteristic areas. This makes it possible to perform the most suitable processing in response to the input image signal so that the impression of contrast is improved.

摘要： A gas-mixture-ignition-time estimation apparatus for an internal combustion engine estimates the temperature of a premixed gas mixture for PCCI combustion (i.e., cylinder interior temperature Tg), while relating it to the angle CA, on the basis of a state quantity of the cylinder interior gas at the time of start of compression (CAin) (heat energy of the cylinder interior gas at the time of start of compression), the amount of a change in the state quantity of the cylinder interior gas attributable to compression in a compression stroke (minute piston work), and the heat generation quantity of a cool flame generated in PCCI combustion prior to autoignition (hot flame) (cool flame heat generation quantity Aqlto). A time when the cylinder interior temperature Tg reaches a predetermined autoignition start temperature Tig is estimated as an autoignition start time (Caig) of the premixed gas mixture related to PCCI combustion. Since the cool flame heat generation quantity Oqlto is taken into consideration, the autoignition start time related to PCCI combustion can be estimated accurately.
摘要翻译：用于内燃机的气体混合燃烧时间估计装置估计用于PCCI燃烧的预混合气体混合物的温度（即气缸内部温度Tg），同时将其与角度CA相关联，基于状态量压缩开始时的气缸内部气体（CAin）（压缩开始时的气缸内部气体的热能），由压缩引起的气缸内部气体的状态量的变化量压缩行程（分钟活塞），以及自燃（热焰）之前的PCCI燃烧产生的冷焰（冷焰产生量Aqlto）的发热量。气缸内部温度Tg达到预定自燃起始温度Tig的时间被估计为与PCCI燃烧相关的预混合气体混合物的自燃起始时间（Caig）。由于考虑了冷焰发热量Oqlto，因此可以准确地估计与PCCI燃烧有关的自燃开始时间。
