Abstract: An aerial support platform is supported to extend below, and intermediate of, a pair of parallel cables mounted along respective opposite walls of a studio. A carriage rides on each of the parallel cables, and another pair of cables extends to connect the pair of carriages. A third carriage sits on the other pair of cables, and a series of further cables extend vertically from that carriage to the platform. The pair of carriages positioned on the opposite walls of the studio are controlled to move in tandem, and the third carriage has controlled movement between those carriages. The platform may be raised or lowered relative to the third carriage, and thus has three linear axes of motion. The platform has two additional axes of motion, both rotational. One is around a vertical axis and another is around an axis normal to the vertical axis. Cinematographic equipment may be fixed to the platform, which can then be oriented using a computer at a remote location.

In a preferred embodiment, an array of such detectors, each with an imaging surface and a non-uniform spatial sensitivity across the surface, is used to measure the image. In another preferred embodiment, the detector(s) measures the image more than once, each time with the relative position between the image and the detector(s) changed. The measured outputs are interlaced together and deconvolved by an inverted model of the detector(s) to re-construct the image.

Abstract: The present invention provides a color selecting mechanism for a cathode ray tube in which an enough area of an effective screen area of a color selecting electrode can be ensured. A frame (1) is constituted by a pair of opposite long-side frames (3) and a pair of opposite short-side frames (4).

Abstract: A color video projection video system in which a white light source is separated into red, green and blue bands with dark guard bands spaced therebetween. Scanning optics cause the colored bands to be sequentially scanned across a light valve, such as a transmission LCD panel. Prior to each color passing over a given row of on the light panel on the light valve, that row will be addressed, by the display electronics with the appropriate color content of that portion of the image which is being displayed. The image is projected by a projection lens onto a viewing surface, such as a screen. In order to optimize the color purity of the system when used with certain types of light valves, the intervals between each of the three colors is adjusted and scaled to the differing response times of the LCD panel for each of the colors. Additionally, color balance can be adjusted by changing the relative size of each color band with respect to the others.

Abstract: A video camera system for generating a shutter pulse for operating a photo-camera or other still image recording means in response to detecting a predetermined magnitude change in an average level of a pick-up signal representative of an image. As a detecting signal, both level detecting signals for an iris control and an AGC control, for example, are used. When the status of a foreground object zone is changed with movement of a person or an object, the level change of the image pick-up signal becomes a value larger than a predetermined value and a shutter pulse is automatically generated.

According to this mechanical chassis supporting mechanism, it is possible to prevent an external stress from being applied to the mechanical chassis as a twisting deform force.

Abstract: A number of photodiodes are arranged in line and dark output generating diodes are associated with the respective photodiodes. The light incident side of each dark output generating diode is shielded by a metal film.

Alternatively, the charges transferred through the two thin-film transistors are respectively stored in first and second capacitors, and charges corresponding to the difference between the charges of the first and second capacitors are obtained by a differential amplifier and stored in a third capacitor.

Abstract: An image processing apparatus capable of displaying an object on right and left screens so that the object an be visually examined as usually seen by the naked eye. When visual examination positions of right and left displays (1, 2) are detected by eye cameras (3, 4), the visually examined object (WK) on the screens (1, 2) is specified on the basis of the detected visual examination positions. A position of the object (WK) on one screen (1a) is fixed and an entire image including the object (WK) is shifted on the other screen (2a) so that a position of the object (WK) on the other screen (2a) becomes the same to the fixed position on the one screen (1a). A processing is performed to darken a portion of the screen (2a) which is not displayed on the screen (2a) before the image shifting and is displayed on the screen (2a) as a result of the image shifting, and also to darken a portion of the screen (1a) corresponding to the darkened part of the screen (2a) so that the corresponding part is also darkened.
