摘要： PROBLEM TO BE SOLVED: To provide a projection type picture display device realizing the display of a picture suitable for observation in accordance with a video scene.
SOLUTION: The projection type picture display device is provided with 1st and 2nd variable diaphragm mechanisms 43 and 44 in a projection unit 14. The mechanisms 43 and 44 are arranged in an illumination optical system and a projection optical system respectively and adjust an effective luminous flux diameter. A diaphragm control part 64 controls the mechanisms 43 and 44 so that the appropriate effective luminous flux diameter may be obtained in accordance with the luminance level of an inputted video signal. The effective luminous flux diameter is adjusted to be large when the luminance level is high and small when the luminance level is low. Since the peripheral light of luminous flux is cut when the effective luminous flux diameter is made small, contrast is made high. Thus, the picture is brightly displayed on the scene where the luminance level of the video is high and is displayed with high contrast on the scene where the luminance level is low.

摘要翻译：要解决的问题：提供实现根据视频场景适合观察的图像的显示的投影型图像显示装置。
解决方案：投影型图像显示装置在投影单元14中设置有第一和第二可变光阑机构43和44.机构43和44分别布置在照明光学系统和投影光学系统中，有效光通量直径。光阑控制部分64控制机构43和44，使得可以根据输入的视频信号的亮度水平获得适当的有效光通量。当亮度水平较低时，有效光束直径被调节为较大，当亮度水平较低时。由于当有效光束直径变小时，光通量的外围光被切断，所以对比度变高。因此，在亮度水平较低的场景下，在视频的亮度水平高的场景下以高对比度显示的场景下，图像被明亮地显示。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive and hardly broken-down light pen which can be safely used as a pointing means for a material presenting device by dispensing with arranging any switch mechanism at the pen top. SOLUTION: In a state that a switch 13 of the light pen 1 is turned on, and an LED 12 is made to always emit light, the top end of the light pen 1 is pressurized to apply a stroke pressure to material D or a monitor 60 on a material placing stand 40 where a virtual screen S is set. Then, a top end cover 21 is elastically deformed, and a slit 11a is split, and the LED 12 is exposed, so that a light emission instructing state is generated. The image of the LED 12 is captured through an imaging part 50 to a control part 42. The control part 42 calculates the coordinates of the LED 12 in the virtual screen S, and synthesizes the point image at the coordinates of the display image of the screen corresponding to the coordinates of the LED 12. When the light pen 2 is released, the LED 12 is shielded by the top end cover 21, and the LED 12 is apparently turned off. COPYRIGHT: (C)2005,JPO&NCIPI
