摘要： A projector apparatus comprises an image signal processor (2) for generating color drive signals of at least four channels, which correspond to at least four kinds of colors including colors selected according to the spectrum of a light source, from the three primary color image signals; a light-splitting device for splitting the light from the light source into at least four kinds of light according to the colors corresponding to the color drive signals generated in the image signal processor (2); light valves (LB), each of which comprises a liquid crystal element driven by the color drive signal for modulating each light component split from that of the light source by the light-splitting device; and a combining device for combining the light components modulated by the light valves.

摘要： The present invention provides a liquid crystal projector apparatus and a driving method for a liquid crystal projector apparatus, which can display an image with an optimum picture quality free from an influence of a temperature variation of a liquid crystal panel without the necessity to directly measure the temperature of the liquid crystal panel. The liquid crystal projector apparatus includes a temperature sensor for detecting a temperature at a location in the liquid crystal projector apparatus except liquid crystal panels, a memory for storing temperature detection data obtained by the temperature sensor within a period from a power supply starting time to a steady operation entering time of the liquid crystal projector apparatus, arithmetic operation means for estimating a temperature of each of the liquid crystal panels based on the temperature detection data stored in the memory to indirectly obtain the temperatures of the liquid crystal panels, and liquid crystal drive sections for correcting drive voltages for driving the liquid crystal panels with output signals of the arithmetic operation means and applying the corrected drive voltages to the liquid crystal panels.
摘要翻译：本发明提供一种液晶投影仪装置和液晶投影仪装置的驱动方法，其能够显示具有不受液晶面板的温度变化影响的最佳图像质量的图像，而不需要直接测量液晶面板的温度。液晶投影仪装置包括用于检测除了液晶面板之外的液晶投影仪设备中的位置处的温度的温度传感器，用于存储由电源开始时间到期间内由温度传感器获得的温度检测数据的存储器根据存储在存储器中的温度检测数据来估计每个液晶面板的温度的算术运算装置，以间接获得液晶面板的温度，以及液晶驱动器用于通过算术运算装置的输出信号校正用于驱动液晶面板的驱动电压的部分，并将校正的驱动电压施加到液晶面板。
