Abstract: An electronic still camera is disclosed which adjusts focus to an object image by mechanically moving an electronic sensor within the electronic still camera. The electronic sensor is moved along an optical path of the electronic still camera. In this way, the sensor follows the focal plane of the image, thus tracking a focused image.

Abstract: A color component separation camera is provided with a shutter blade mechanism in which the different color exposing filters are integrated to provide a quick series of succeeding color component exposure intervals. The blade mechanism comprises two overlapping independently driven lightweight shutter blade elements comprising filtered and unfiltered apertures arranged in side-by-side relation for selective movement into the image light path in a manner whereby a plurality of different color component separation exposure intervals may be implemented in rapid succession. In one embodiment, one shutter blade element includes three aligned apertures wherein the middle aperture is unfiltered and the end apertures are filtered at different wavelengths. The other shutter blade element comprises two aligned spaced apart apertures in which one aperture is filtered at still another wavelength and the other aperture is unfiltered.

Abstract: A method and apparatus for exposure control of electronic imaging cameras capable of video and still modes of operation and having an automatic variable aperture diaphragm to control image light passing to a sensor during the video mode of operation. Relatively short exposure time intervals are attained in the still mode of operation by attenuating light passing to the sensor during the video mode so that the aperture to which the variable aperture diaphragm is set is increased over that to which it would normally be adjusted during video operation. Upon conversion to the still mode, the filter attenuation is rapidly removed resulting in a correct aperture setting for the relatively shorter still mode exposure time intervals. In the video mode, electronic shutter operation is effected in the conventional manner. In the still mode of operation, the exposure time interval is established either by a combination of electronic shutter operation and mechanical shutter operation or by mechanical operation alone.

Abstract: Transverse mounting of the arc tube within the lamp jacket is effected through a mount featuring a hinged selflatching attachment of the arc tube to a support rod extending the length of the jacket and serving also as electrical connector to one electrode. A flexible connector makes connection to the other electrode. During manufacture the hinges permit the arc tube to be folded in line with the support rod for passage through the neck and then to be transversely erected in the jacket, and the latch thereupon locks the arc tube in the transverse attitude.

Abstract: Transverse mounting of the arc tube within the lamp jacket is effected through a mount featuring a hinged attachment of the arc tube between divergent support rods which serve also as electrical connectors to the electrodes. During manufacture the hinges permit the arc tube to be folded in line with one support rod attached at the stem leading and the other trailing for passage through the neck, and then allow the arc tube to be transversely erected in the jacket after which the other rod is attached at the stem. Erection of the arc tube simultaneously causes leaf springs to engage the sides of the bulb and centralize the arc tube in its transverse attitude.
