    • Provided are a display device, a computer program, a storage medium, and an image displaying method, which are capable of adjusting a light intensity of a display panel without using a photometric image. An optical sensor 5 measures the light intensity (tristimulus value) from a partial display area of a display panel (1) (measurement area of the display panel measured by the optical sensor (5)), and the partial display area has multiple pixels. A computation unit (20) computes the luminous intensity (tristimulus value) emanating from the measurement area based on a video level (image data) of each pixel for displaying an image in the measurement area. A comparison unit (19) compares the computed light intensity with the measured light intensity. A control unit (10) adjusts the light intensity (luminance, chromaticity, or the like) of the display panel (1) based on a comparison result by the comparison unit (19).
    • 提供能够在不使用测光图像的情况下调整显示面板的光强度的显示装置,计算机程序,存储介质和图像显示方法。 光学传感器5测量来自显示面板(1)的部分显示区域(由光学传感器(5)测量的显示面板的测量区域))的光强度(三刺激值)),并且部分显示区域具有多个像素。 计算单元(20)基于在测量区域中显示图像的每个像素的视频电平(图像数据)来计算从测量区域发出的发光强度(三刺激值)。 比较单元(19)将计算的光强度与测量的光强度进行比较。 控制单元(10)基于比较单元(19)的比较结果来调整显示面板(1)的光强度(亮度,色度等)。

    • The present invention relates to a display device that measures display characteristics (such as luminance or chromaticity) associated with a display panel. The display device of the present invention has a light sensor (5) provided at a position allowing outgoing light from a screen (1a) of a liquid crystal panel (1), which serves as the display panel, and extraneous light reflected on the screen (1a) to enter the light sensor (5). Since the light sensor (5) is provided at the position, it is possible to measure the characteristics of the display panel and also the characteristics of the extraneous ambient light reflected on the screen. Thus, it is possible to accurately adjust the display characteristics based on the measurement results.
    • 本发明涉及一种测量与显示面板相关联的显示特性(如亮度或色度)的显示装置。 本发明的显示装置具有:光传感器(5),设置在允许来自作为显示面板的液晶面板(1)的屏幕(1a)的出射光的位置以及在屏幕上反射的外来光 (1a)进入光传感器(5)。 由于光传感器(5)设置在该位置,因此可以测量显示面板的特性以及在屏幕上反射的外部环境光的特性。 因此,可以基于测量结果精确地调整显示特性。
