Abstract: In fixing prisms for a TV camera and solid-state image pickup element packages, two holding plates are fixed at two sides of each of the prisms, each of the holding plates having a wedge-shaped or semicircular tip surface, and an adhesive is provided in a gap formed by a surface of the solid-state image pickup element package and the wedge-shaped or semicircular tip surface of the holding plate, respectively. Then, relative to light axes, X, Y and Z axes and rotational axes ?x, ?y and ?z for the axes X, Y, and Z of the solid-state image pickup element packages are aligned while inclining the holding plates in a front-rear direction simultaneously. The adhesive is cured by applying light or heat to thereby fix the holding plates, the solid-state image pickup elements and the prisms, respectively.

Abstract: A filed sequential color camera system includes a color camera, and an illumination unit. The color camera includes a separation optical system to separate an optical image of a subject incident from a lens in two directions; two solid-state imaging devices to convert into electric signals the respective optical images separated in the two directions; an electronic shutter control device to apply sequential exposure control to the two solid-state imaging devices within a time corresponding to a ½ frame for each one frame and at a non-overlapping interval; and a light-emitting sync signal output device to produce a light-emitting sync signal in sync with the sequential exposure control by the electronic shutter control device. The illumination unit receives the light-emitting sync signal from the color camera to emit multicolor light having different wavelength ranges in sync with exposure control of the solid-state imaging devices and in a sequential switch mode.

Abstract: The invention provides a field sequential color camera system wherein a light-emitting strobe or diode with invisible light such as infrared or ultraviolet light added to red, green and blue visible light is combined with an illumination unit capable of emitting light in a field sequential mode so that high-definition images are finished and obtained at two frames.

Abstract: The present invention provides a visible and infrared light photographing lens system. A color separating prism or the like divides an object light entering a photographing lens and then passing through a focus lens, into an object light in a visible light region and an object light in an infrared light region. A visible light image pickup element and an infrared light image pickup element are used to pick up images of the respective object lights. Further, a compensation lens can be used to adjust a position where an image of the object light in the infrared light region is formed. Consequently, visible light photographing and infrared light photographing can be simultaneously carried out by focusing on an object at the same distance.

Abstract: Conventional methods for fixing a solid-state image pickup element to a color separation prism have a problem in that, if the amount of an applied ultraviolet-curable adhesive is nonuniform and ultraviolet light irradiation is uneven, the ultraviolet-curable adhesive undergoes uneven curing shrinkage, so that the solid-state image pickup element is fixed in a position deviating from an original alignment position.

Abstract: A camera image shake correcting device is provided which employs an image shake correcting system using an optical system to prevent image quality degradation and which uses a mirror (2) to allow improvement of correction response to image shake as well as miniaturization and to achieve a cost reduction. The camera image shake correcting device is characterized by having a mirror (2) disposed in an intermediate portion of an optical path connecting together an image-formation plane of an image pickup optical system of a camera and an imaging lens; mirror driving means (7) for driving the mirror (2) so that the angle of the mirror (2) is changed in correspondence to displacement of an image on the image-formation plane caused by shake of the camera to cancel the displacement of the image on the image-formation plane; and control means (6) for controlling the mirror driving means (7) by detecting the amount of shake of the camera or the amount of displacement of the image on the image-formation plane.

Abstract: In a TV camera main body, a still-image-luminous-flux-decomposing prism is disposed adjacent to a color-decomposing prism of a TV-image-capturing system, whereby still images whose aberration is favorably corrected as with TV images are obtained in a simple and compact configuration. A mechanical shutter is disposed in an optical path of the still-image-capturing system, so as to prevent image blurring and smear from occurring due to temporal shifts between field images. A four-block color-decomposing prism 11A, in which each glass prism has a form identical to a color-decomposing prism of a dual green type, is constituted by a still-image-capturing prism 2d, and a TV-image-capturing three-color-decomposing prism system comprising a prism for blue 2a, a prism for red 2b, and a prism for green 2c. A mechanical shutter 34 is disposed between the light exit end face 7d of the still-image-capturing prism 2d and its cover glass 6d.

Abstract: In a still-image-capturing system, a still-image-capturing lens group having totally the same configuration (the same number of lens sheets, lens form, and lens material) as the lens group used only for a TV-image-capturing system is disposed downstream a half mirror, and a rectangular prism is disposed for providing a luminous flux with an optical path length identical to that within a color-decomposing prism when the luminous flux passes therethrough. In another aspect, a focal length conversion lens group for changing the focal length of zoom lens groups and a total reflection mirror is disposed on the optical axis of the zoom lens groups exclusively from each other. In still another aspect, an electronic still camera is attached to the still-image-capturing system.

The solid state imaging device has a first mode in which the light receiving signals on two adjacent scanning lines arranged in the vertical direction are added to each other and outputted, and a second mode in which the light receiving signals on one scanning line are sequentially outputted in units of scanning lines, the first and second modes being optionally selectable in accordance with a predetermined mode selection signal.
