摘要： A projector has a liquid crystal display panel for displaying an image, a lamp for illuminating the liquid crystal display panel, and a projection optical system for projecting light modulated by the image displayed. The lamp is held by a member whose position is variable to allow fitting of different types of lamp. The projector acquires data related to the lamp currently fitted and controls the light emission of the lamp on the basis of that data. The data includes the life of the lamp, so that the projector prevents the lamp to be lit longer than its remaining life. The remaining life is updated in accordance with how long the lamp has been lit. In addition to the lamp that is lit, an auxiliary lamp may be fitted so that the lamp that is lit can be switched to the auxiliary lamp as required. The lamp is formed into a single lamp unit together with a reflector or a casing to prevent the user from touching the lamp. The lamp is accessible for replacement only when it is in a predetermined position, where the lamp is never allowed when hot.
摘要翻译：投影仪具有用于显示图像的液晶显示面板，用于照亮液晶显示面板的灯和用于投影由所显示的图像调制的光的投影光学系统。灯由位置可变的构件保持，以允许安装不同类型的灯。投影机获取与当前安装的灯有关的数据，并根据该数据控制灯的发光。数据包括灯的使用寿命，因此投影机可以防止灯泡比其剩余寿命长。剩余寿命根据灯已点亮多长时间进行更新。除了点亮的灯之外，还可以安装辅助灯，使得点亮的灯可以根据需要切换到辅助灯。灯与反射器或壳体一起形成为单个灯单元，以防止使用者接触灯。只有当灯处于预定位置时，才能进行更换，否则灯在热时不允许。

摘要： A structure for holding lenses in which they are inserted into a lens frame in an axial direction thereof for their mounting thereon, and in which a lens that is first inserted into the lens frame is fixed thereto by caulking a part of the lens frame against the lens, so that an enlargement in a radial direction of the lens frame is prevented. The lens frame has three through-holes in a circumferential direction with an equal space therebetween in which the through-holes form around an intermediate position thereof relative to the axial direction, a stepped surface on a first end opposite a second end from which the lens is inserted, and a partial caulking projection which forms inside each hole as a part of the lens frame. After the first lens is inserted from the second end into the lens frame, the partial caulking projection is thermally caulked against a periphery, of the lens, which is downstream relative to the direction in which the lens is inserted, so that the first lens is held between the stepped surface and the partial caulking projection.

摘要： An image playback method is provided which allows the viewer to easily recognize how much time has elapsed and to evoke, with nostalgia, the memories from the time when the image was acquired. This image playback method includes the steps of determining a time elapsed from image acquisition based on an acquisition date and time of image information obtained by the image acquisition and a current date and time; determining a fading rate based on the determined elapsed time; subjecting the image information to image processing in which the image information is faded based on the determined fading rate; and displaying the image-processed image information to play back the image.
