Abstract: The optical path changing device of the present disclosure includes an optical member having a parallel plate face for changing an optical path, and first, second, and third actuators. The first, the second, and the third actuators are connected with the optical member at first, second, and third vertices of a triangle imaginarily drawn on a plane parallel to the parallel plate face of the optical member. The first, the second, and the third actuators drive the optical member forward and backward in a normal direction of the parallel plate face at the first, the second, and the third vertices serving as points of load. The optical member has a center of gravity within the triangle when seen from the normal direction.

Abstract: An information processing device is an information processing device that outputs a video stream by using a video captured by an imaging device capable of changing at least one parameter among pan, tilt, and zoom, and includes a parameter controller that controls at least one parameter of the imaging device. The parameter controller instructs the imaging device to change the at least one parameter, and outputs a switching permission signal for permitting switching of the video stream output from the information processing device when the change of the at least one parameter of the imaging device is completed.

Abstract: The projection image display apparatus includes a display element that emits image light generated by modulating light from a light source based, a pixel-shifter that shifts a pixel of a projected image by changing an optical path of the image light, a resampling circuit, a motion-interpolation image processing circuit, and a pixel-shift controller. The resampling circuit generates a plurality of sub-frame image signals having a resolution of the display element, by resampling an image signal having a resolution of the projected image. The motion-interpolation image processing circuit provides a motion-interpolation image process to the sub-frame image signals. The pixel-shift controller receives the sub-frame image signals having undergone the motion-interpolation image process. The pixel-shift controller drives the display element and the pixel shifter at a given timing based on the sub-frame image having undergone the motion-interpolation image process, and then displays the projected image, which involves pixel-shift, on a screen.
