Abstract:
An infrared polarizing filter is attached to an infrared synchronization signal radiator of a stereoscopic image display device which alternately displays right and left images by time-division with polarized light in one direction to radiate the polarized-light infrared synchronization signal. The problem with the occurrence of crosstalk is solved. Stereoscopic image appreciation eyeglasses have polarizing plates, visual field opening/closing liquid crystal cells and tilt correcting liquid crystal cells. The synchronization signal is received by a receiver mounted on an eyeglass frame. The tilt correcting liquid crystal cells are adjusted based on the eyeglass frame tilt angle detected.
Abstract:
To provide a stereoscopic video receiver that generates a stereoscopic video with a sense of stereoscopy and a powerful impression even when a left-eye screen and a right-eye screen are displayed on a small-sized display, a left-eye screen and a right-eye screen shot by a stereo camera to be displayed on a display having a width narrower than that of a virtual display are displayed so as to be displaced in a direction of separating these screens away from each other, and left and right fields of vision are matched with each other at a position away from the display and a distance between left and right corresponding points of an infinite distance subject image is set to be shorter than an interpupillary distance of a viewer.
Abstract:
A problem to be solved is to enhance the charge and discharge characteristics and rate characteristics of a B-type titanium oxide (TiO2(B)) powder by a simple treatment and to provide a B-type titanium oxide powder that can be suitably used as a negative electrode material for a lithium ion battery. A B-type titanium oxide powder is allowed to undergo a reaction under a fluorine-containing gas atmosphere at 0° C. to 200° C. for 1 minute to 10 days to obtain a surface-fluorinated B-type titanium oxide powder. It is preferred that the fluorination treatment is performed at 0.01 atm to 2 atm. It is preferred that a gas containing a fluorine compound selected from a fluorine (F2) gas, a nitrogen trifluoride (NF3) gas, a perfluorotrimethylamine (N(CF3)3) gas, a chlorine trifluoride (ClF3) gas and the like is used as the fluorine-containing gas.
Abstract:
An infrared polarizing filter is attached to an infrared synchronization signal radiator of a stereoscopic image display device which alternately displays right and left images by time-division with polarized light in one direction to radiate the polarized-light infrared synchronization signal. In order to solve the problem with the occurrence of crosstalk, stereoscopic image appreciation eyeglasses (30) are configured in such a manner that polarizing plates (33) are arranged side-by-side in the right and left visual fields, and visual field opening/closing liquid crystal cells (31) and tilt correcting liquid crystal cells (32) are arranged one on another on the front surfaces of the polarizing plates (33), that the polarized-light infrared synchronization signal is received by a synchronization signal receiver (37) mounted on an eyeglass frame, the visual field opening/closing liquid crystal cells (31) are driven in synchronization with each other, the right and left visual fields are alternately opened/closed relative to the display light of the stereoscopic image display device, and the voltage which is controlled by tilt angle data detected by a tilt angle detector mounted on the eyeglass frame according to the tilt of the eyeglasses is applied to the tilt correcting liquid crystal cells (32), and that the rotating light angle of the tilt correcting liquid crystal cells (32) is adjusted, and the shielded state at the time of closing the visual fields is always the maximum.
Abstract:
An image pickup substrate mounted with an image pickup element is pressed against the surface of a camera body frame by a plate spring, and exclusive position adjusting mechanisms that independently move the image pickup substrate to a vertical direction and a lateral direction are provided. The image pickup substrate is provided so that its position can be adjusted and a projected image by means of a photographing lens is imaged on the image pickup element. Vertical lines and lateral lines are displayed as software display on an electronic display, and their positions can be independently adjusted to the lateral direction and the vertical direction. A dustproof plate is fixed between an interchangeable lens section and a camera main body, so as to prevent dust from adhering to the surface of the image pickup element.
Abstract:
An object of the present invention is to perform matching adjustment between left and right screens easily and accurately in a digital stereo camera and/or a digital stereo video camera at a photographing time or after photographing. A stereo viewfinder 3 of a digital stereo camera 1 is constituted of a pair of left and right liquid crystal displays and eyepiece lenses 10. Such a constitution is adopted that aspect ratios of left and right image display regions of the liquid crystal displays is made narrower than aspect ratios of image capture regions of image capture devices and horizontal scrolling is performed symmetrically regarding the left and right. Images on the image capture devices are horizontally scrolled, while finder images are viewed in a stereoscopic manner with both eyes, so that perspective of a stereoscopic image changes and an optimally scrolled image data can be photographed. Scroll adjustment can be performed on image data after photographed, and stereo photographs giving an optimal stereoscopic feeling can be printed from edited image data.
Abstract:
A stereo slide mount can reproduce an accurate stereo effect to facilitate easiness of mounting operation and accurate positioning. Plural types of stereo slide mounts 1 (#1 to #n) that widths W of windows stepwisely decrease have the same pitch Pw of the windows and different width W of the windows and fitting pitches of right and left films. A base film is provided with a positioning pin 6 for engaging perforations of the film, and a cover frame is provided with pin holes 7 to be engaged with the positioning pins 6. The positioning pins 6 and the pin holes 7 are provided at positions that the inner vertical sides of the windows are brought into agreement with the inner edges of the pictures of the film. The stereo slide mount having smaller widths of the windows increases gap width (P.sub.0, P.sub.1, P.sub.2, . . . ) between two sets of right and left positioning pins 6 to extend the pitches of the right and left films, and the outer masking amounts of the right and left films increase.
Abstract:
A stereo slide viewer can appreciate a stereo image without cutting a roll film photographed by a stereo camera. A film feeder 3 for feeding a roll film F is mounted at the rear of a table 2 of the stereo side viewer 1, and a pair of right and left projection lenses 5R and 5L are provided at the intermediate of the table 2. A pair of right and left focal plates 9R and 9L are mounted at the front of the table 2, and eyepieces 11R and 11L are installed oppositely at the focal plates 9R and 9L. The back surface of the film feeder 3 is illuminated by an illuminator, and one set of images are focused on the right and left focal plates 9R and 9L through the windows of the film feeder 3.
Abstract:
The present invention is to improve the visibility of a cutting position of a developed reversal film, and in the invention perforations are provided in upper and lower sides of a photographic film at the same pitch as that of the photographic area of a camera. A V-shaped groove is provided in the perforation at a longitudinally central position. The V-shaped grooves in the upper and lower perforations serve as an accurate target for cutting by taking photos with a camera designed such that the perforations are situated at gap portions G between photographic areas or frames.
