摘要:
An image display apparatus has a signal input portion for receiving an image signal, an image compensator for electrically compensating the image signal for distortion so that a left and a right image displayed in an observer's left and right eyes have identical distortion and then outputting a left and right image signal that correspond to the left and right images, a signal switcher for switching between the left and right image signals output from the image compensator so as to output the left and right images alternately chronologically, a single two-dimensional image display device for displaying a two-dimensional image in accordance with the image signal output from the signal switcher, a pair of left and right eyepiece optical systems for directing image light exiting from the two-dimensional image display device to the observer's left and right eyes so that the two-dimensional image is displayed as a virtual image in the observer's eyes, and an optical path switcher for time-divisionally switching optical paths from the two-dimensional image display device to the observer's eyes in synchronism with switching between the left and right image signal output from the signal switcher so that the image light enters either the observer's left or right eye at a time.
摘要:
An image forming optical system according to the present invention is characterized in that, in an image forming optical system having a positive lens group, a negative lens group, and an aperture stop, the positive lens group is disposed at an object side of the aperture stop, the positive lens group has a cemented lens which is formed by cementing a plurality of lenses, in a rectangular coordinate system in which a horizontal axis is let to be Nd and a vertical axis is let to be νd, when a straight line indicated by Nd=α×νd+β (where, α=−0.017) is set, Nd and νd of at least one lens forming the cemented lens is included in both of areas namely, an area which is determined by a line when a lower limit value is in a range of a following conditional expression (1a), and a line when an upper limit value is in a range of the following conditional expression (1a), and of an area determined by following conditional expressions (2a) and (3a). 1.45

摘要:
When one mobile device is activated, the existence of information which other mobile devices hold is also confirmed. There is provided a mobile device system including a plurality of mobile devices, wherein each mobile device includes a communication unit for communicating with other mobile devices, an information storage unit for storing information, a list storage unit for storing a list of information stored in the information storage unit and in the information storage units of the other mobile devices, a display unit, and a control unit. The control unit displays the list stored in the information storage unit on the display unit and, when information stored in the information storage unit of another mobile device is specified, requests transmission of information from the other mobile device using the communication unit and displays information transmitted in response to the request on the display unit.
摘要:
The invention provides a mobile device system and a mobile device that can flexibly respond to situations where the user carries a different combination of mobile devices on different days, and can prevent the mobile devices from being misplaced. The mobile device system includes three or more mobile devices, wherein each mobile device includes a device detection unit for periodically detecting other mobile devices located within a predetermined range of the mobile device, a function-restricting unit for restricting a predetermined function, and a control unit, and when two or more mobile devices of the other mobile devices detected by the device detection unit are no longer detected, the control unit operates the function-restricting unit.

摘要:
An image reproducing apparatus reproduces a still picture recorded on a silver-halide film and a moving picture recorded on a video tape. The image reproducing apparatus also reproduces simultaneous shooting information recorded on both the film and the video tape. The image reproducing apparatus has a controller which controls reproduction of the pictures recorded on the film and the video tape in accordance with the simultaneous shooting information.
