摘要： A lens shift mechanism includes a projection lens drive unit, a vertical-horizontal limit sensor which detects that a projection lens apparatus reaches a limit in a shift range in vertical and horizontal directions, and a vertically-horizontally central sensor which detects that the projection lens apparatus reaches a central position in the shift range. The vertically-horizontally central sensor has a detection width having a central value at the central position. When a microcomputer automatically returns the projection lens apparatus to the central position within the shift range after a shift operation, the microcomputer shifts the projection lens apparatus in a forward direction directed from a position at a time point when automatic return is started toward the central position, and thereafter shifts the projection lens apparatus again in a backward direction by substantially half the detection width of the vertically-horizontally central sensor.

摘要： A central position detection section has a detection width in which the central position has a median value along one axial direction. When the direction from a position, which is located at the time at which returning is started toward the central position is defined as a go direction, the control section commands that a drive mechanism should sequentially perform following operations: a first operation of driving a projection lens assembly in the go direction; a second operation of allowing the projection lens assembly to travel in a return direction at least by the detection width; and a third operation of allowing the projection lens assembly to travel in the detection width in the go direction by ½ of the detection width traveled in the go direction.

摘要： A projection-type picture display device for displaying an entire OSD image in a state superimposed on a picture without any part of the OSD image overhanging from the picture. An aspect ratio changing unit adjusts the size of the picture by changing an aspect ratio of the picture. An image generation unit generates the OSD image including characters superimposed on the picture. An image synthesizing unit synthesizes the OSD image with the picture of which the aspect ratio has been changed to superimpose the OSD image on the picture. A trapezoidal distortion correction unit performs trapezoidal distortion correction on the picture that has been synthesized with the OSD image in the image synthesizing unit. The image generation unit adjusts the size of the characters in the OSD image in accordance with the size of the picture of which the aspect ratio has been changed.

摘要： An electronic device with an opening/closing door of the present invention includes a device body in which an opening is defined, a shutter system capable of covering and exposing the opening, and a loosely fixing mechanism. The shutter system includes a door capable of moving back and forth between a closed position for covering the opening and an open position for exposing the opening, an arm swingably supported by the device body and having a front end engaging with the door, a motor for opening and closing the door by driving the arm, and a controller for controlling the operation of the motor. The controller is capable of switching the function of the motor between an electric motor and an electric generator. The loosely fixing mechanism is linked to the arm of the shutter system, and loosely fixes the arm when the door is placed at the open position, while loosely fixing the arm when the door is placed at the closed position. The controller causes the motor to function as an electric motor in the process of opening and closing the door, while causing the motor to function as an electric generator when the door is loosely fixed at the open position or at the closed position.
